Why Organ Meats? The Ancestral Case {#why-organs}

For most of human history, muscle meat was not the prized cut. The liver, heart, kidneys, and other organs were the first parts consumed after a kill — the most nutritionally dense, the most valued. In traditional cultures across every continent, nose-to-tail eating was not a philosophy. It was just how people ate.

The shift away from organ meats is recent, largely Western, and driven by industrial food systems that defaulted to muscle meat because it scales better, ships better, and sits better on a supermarket shelf. The ancestral wisdom was not replaced with something nutritionally superior. It was simply abandoned.

The consequence — documented in successive Australian Bureau of Statistics nutrition surveys — is a population that chronically under-consumes several of the nutrients most concentrated in organ meats: preformed vitamin A, heme iron, vitamin B12, selenium, copper, and CoQ10. The same nutrients that are hardest to obtain in adequate quantities from muscle meat, fortified foods, or plant sources alone.

This guide covers each of the five organ types used in Vital Origin's supplement range: what the USDA nutrient data shows for each, what makes each one nutritionally distinctive, and how they fit together in a complete nose-to-tail approach.

A note on freeze-drying

All Vital Origin organ supplements are raw freeze-dried (lyophilised). This matters for two reasons. First, freeze-drying removes moisture at low temperatures — below the thresholds that degrade heat-sensitive nutrients like B vitamins, CoQ10, and naturally occurring enzymes. Second, freeze-drying from raw means the nutrient profile of the finished capsule is comparable to raw organ meat — the closest match to whole food. Heat-based desiccation, the alternative processing method, introduces temperatures that measurably reduce certain heat-sensitive compounds.

Beef Liver: Nutrient-Density Leader {#liver}

No organ comes close to beef liver on raw nutrient concentration. It is, by any reasonable measure, the most nutrient-dense food in the human food supply — a statement backed by USDA FoodData Central reference data, not marketing.

What the USDA data shows

Per 100g raw beef liver (USDA FDC entry 169451 [1]):

• Vitamin A (retinol): 4,970 µg RAE — approximately 710% of the adult women's RDI
• Vitamin B12: 59.3 µg — approximately 2,471% of the adult RDI
• Copper: 9.76 mg — approximately 813% of the adult RDI
• Folate (food-folate): 290 µg — approximately 73% of the adult RDI
• Riboflavin (B2): 2.76 mg — approximately 251% of the adult women's RDI
• Selenium: 39.7 µg — approximately 66% of the adult RDI
• Iron (heme): 4.90 mg — in the most bioavailable form

Per-serve breakdown — Vital Origin Beef Liver Capsules

A standard 6-capsule daily serving is equivalent to approximately 15g of raw beef liver. Based on USDA FDC 169451 reference data, that delivers approximately:

Vitamin A and copper are the headline figures — both exceeding the adult RDI in a single daily serve. B12 lands at over three times the RDI, in its natural whole-food form rather than the synthetic cyanocobalamin found in most supplements.

Vitamin A: context and safety

Beef liver's vitamin A concentration warrants a clear explanation, not avoidance. Vitamin A is fat-soluble and accumulates in the body. The Australian NHMRC sets the Tolerable Upper Intake Level (UL) for adults at 3,000 µg RAE per day [2]. A 6-capsule serve of Vital Origin Beef Liver Capsules provides approximately 745 µg RAE — about 25% of that UL, and broadly in line with the adult RDI of 700 µg. It sits comfortably within safe ranges for most healthy adults.

The main consideration is for pregnant women: Australian and international guidelines advise being mindful of total preformed vitamin A intake during pregnancy. If you are pregnant or planning to become pregnant, consult your healthcare practitioner before taking this product. Avoid combining liver supplements with separate high-dose vitamin A products or cod liver oil.

The food form of vitamin A — retinol as it occurs in liver — is also categorically different from high-dose synthetic retinol supplements. Food-matrix retinol is the form humans have consumed throughout history. The safety concern associated with vitamin A toxicity relates primarily to isolated, high-dose retinol supplementation at levels well above what whole-food sources deliver.

Iron — heme form matters

Beef liver's iron content (~4.9 mg/100g, heme form) is worth noting in its context. Heme iron — the form in animal foods — is absorbed at an estimated 15–35%, compared with 2–20% for non-heme iron from plant foods and most synthetic supplements [3]. That absorption is also far less affected by dietary inhibitors like phytic acid or tannins. For iron-focused buyers, though, liver is not the most iron-dense organ in the range. Spleen — and by extension, products that combine liver, spleen, and whole blood — deliver meaningfully more heme iron per serving. See the Beef Spleen section below and our Ancestral Woman product page.

Beef Heart: The CoQ10 Organ {#heart}

Beef heart is nutritionally distinct from liver in a way that is easy to misunderstand. It is not "just like liver but different flavour." It brings a different set of nutrients — most notably, CoQ10 — that liver does not provide in meaningful amounts.

What the USDA data shows

Per 100g raw beef heart (USDA FDC entry 168625 [4]):

• Vitamin B12: 8.55 µg — approximately 356% of the adult RDI
• Iron (heme): 4.31 mg — bioavailable form
• Selenium: 21.8 µg — approximately 36% of the adult RDI
• Riboflavin (B2): 0.91 mg — approximately 83% of the adult women's RDI
• Niacin (B3): 3.65 mg — approximately 26% of the adult women's RDI
• Vitamin A: 0 µg — beef heart contains no detectable vitamin A per USDA reference

CoQ10: the headline nutrient

CoQ10 is not tracked in the standard USDA nutrient panel, but the peer-reviewed literature is consistent on one point: beef heart is the richest natural dietary source of CoQ10 in any commonly eaten food. Pravst et al. (2010) [5] — the most cited reference on CoQ10 in foods — places raw beef heart at approximately 11 mg of CoQ10 per 100g. Beef liver, by comparison, runs approximately 3.9 mg/100g. Skeletal muscle falls substantially below that. No plant food comes close.

CoQ10 is a fat-soluble compound present in virtually every cell. It plays a role in the mitochondrial electron transport chain — the cellular process by which ATP is produced. The body synthesises CoQ10 endogenously, so it is not classified as an essential nutrient and carries no established NHMRC RDI. Dietary CoQ10 from whole-food sources can contribute to overall intake.

A 6-capsule serve of Vital Origin Beef Heart Capsules (approximately 15g raw equivalent) delivers approximately 1.65 mg of CoQ10 — modest in absolute milligrams, but sourced from the richest natural food form available. Beef heart also provides taurine and carnitine — conditionally essential amino acids found almost exclusively in animal foods, and which many people on plant-predominant diets obtain in very limited quantity.

Per-serve breakdown — Vital Origin Beef Heart Capsules

The absence of vitamin A in beef heart is practically significant: heart and liver are nutritionally complementary, not redundant. Heart brings CoQ10, taurine, and carnitine; liver brings vitamin A, copper, folate, and concentrated B12. Together they cover more ground than either does alone.

Beef Kidney: Selenium, B12, and DAO {#kidney}

Beef kidney sits in a distinct nutritional category — not because it duplicates liver or heart, but because it brings two things that neither of those organs provides in meaningful quantity: exceptional selenium density, and DAO.

What the USDA data shows

Per 100g raw beef kidney (USDA FDC entry 169449 [6]):

• Selenium: 141 µg — approximately 235% of the adult RDI
• Vitamin B12: 27.5 µg — approximately 1,146% of the adult RDI
• Riboflavin (B2): 2.84 mg — approximately 258% of the adult women's RDI
• Iron (heme): 4.60 mg — bioavailable form
• Vitamin A: 419 µg RAE — present but substantially lower than liver's 4,970 µg

Per-serve breakdown — Vital Origin Beef Kidney Capsules

Selenium is the standout figure. Beef kidney is among the most selenium-dense foods in the human food supply. Selenium is a trace mineral involved in antioxidant enzyme activity, thyroid function, and immune support — a nutrient where deficiency is more common than many realise, particularly in regions with selenium-depleted soils. The NHMRC adult Tolerable UL for selenium is 400 µg/day [2]; a standard kidney capsule serve delivers approximately 21 µg, well within safe ranges even combined with dietary sources.

DAO: the most misunderstood kidney nutrient

DAO (Diamine Oxidase) is an enzyme that occurs naturally in several body tissues. Its role involves metabolising histamine — a compound involved in several physiological processes including digestion. Beef kidney is one of the only meaningful dietary sources of DAO in the human food supply.

The correct framing, per TGA guidelines for food products: beef kidney is a source of DAO, an enzyme involved in histamine metabolism. We will not say this product "treats" histamine intolerance or functions as a "natural antihistamine" — those are therapeutic claims that fall outside our regulatory position as a food product. The factual statement is about a nutrient that occurs naturally in the food.

DAO, like all enzymes, is heat-sensitive. This is a specific reason why raw freeze-drying matters for kidney supplements: processing at low temperatures — rather than heat-based desiccation — is the method best suited to preserving enzyme activity in the finished product.

Beef Spleen: The Iron Powerhouse — and the Vitamin A Gap {#spleen}

Beef spleen is underrepresented in public nutrition conversations about organ meats, despite containing the highest iron concentration of any organ in the food supply. It is also the organ that illustrates — most concretely — why multi-organ blends exist.

What the USDA data shows

Per 100g raw beef spleen (USDA FDC entry 169454 [7]):

• Iron (heme): 44.6 mg — the highest of any organ or food in the standard USDA reference database
• Selenium: 62.2 µg — approximately 104% of the adult RDI
• Vitamin C: 45.5 mg — approximately 61% of the adult RDI (an unusually high figure for an animal food)
• Vitamin A: 0 µg — beef spleen contains no detectable vitamin A per USDA reference

That last data point is the most strategically important in this entire guide.

The spleen-vitamin A gap: why it matters for supplement buyers

Spleen has zero detectable vitamin A per USDA FDC 169454. This is not a minor footnote — it directly determines what a single-organ spleen supplement can and cannot deliver.

A standalone spleen supplement provides exceptional heme iron, meaningful selenium, and vitamin C in an animal food. What it cannot provide is vitamin A in any meaningful amount. Buyers who select a spleen-only product for iron density will not receive the vitamin A that is so central to the full nose-to-tail nutritional profile.

This is why multi-organ blends that combine spleen and liver — like Nature's Multi and Ancestral Woman — are nutritionally more complete than either organ alone. The liver component supplies vitamin A; the spleen component amplifies the iron contribution that liver provides only moderately. This is not a marketing arrangement. It is a direct consequence of what each organ's USDA nutrient profile shows.

Vital Origin does not sell a standalone beef spleen product. Spleen is included as a key component in both Nature's Multi (at 20% of the blend) and Ancestral Woman (at 15% of the blend). Both products are described in full in the blend-advantage section below.

Beef Pancreas: Digestive Enzymes and B12 {#pancreas}

Beef pancreas is the least-known organ in the supplement market — and the one that most organ blend competitors simply do not include. That gap exists not because pancreas is nutritionally unimportant, but because it is harder to source at supplement quality.

What the USDA data shows

Per 100g raw beef pancreas (USDA FDC entry 169452 [8]):

• Vitamin B12: 14.0 µg — approximately 583% of the adult RDI
• Iron (heme): 2.22 mg — present but modest
• Selenium: 24.7 µg — approximately 41% of the adult RDI
• Zinc: 2.58 mg — approximately 32% of the adult women's RDI
• Vitamin A: 0 µg — no detectable vitamin A

Naturally occurring digestive enzymes

The nutritional profile of pancreas, while solid, is not the primary reason it appears in Nature's Multi. The more significant attribute is that pancreas tissue naturally contains digestive enzymes — specifically protease, lipase, and amylase. These are the enzymes the pancreas produces in living tissue to facilitate protein, fat, and carbohydrate digestion. In a raw freeze-dried supplement, they are present in the whole tissue as naturally occurring compounds.

To be precise about what we can and cannot say: beef pancreas tissue is a natural source of digestive enzymes — protease, lipase, and amylase — in the context of a whole-food ingredient. We will not claim that these enzymes "improve digestion," "treat enzyme insufficiency," or "boost digestive function." Vital Origin products are food, not therapeutic goods. The factual framing is that pancreatic tissue naturally contains these enzyme proteins.

Most organ blend competitors source four organs: liver, heart, kidney, and spleen. Pancreas does not appear in most blends. Its inclusion in Nature's Multi — alongside the sourcing infrastructure required to supply it — is a genuine point of nutritional difference, not a marketing label.

The Blend Advantage: What No Single-Organ Product Can Match {#blend-advantage}

The case for multi-organ blends is not about convenience. It is about nutritional coverage — and the USDA per-100g reference data for all five organs makes the case without ambiguity.

Here is the per-component reference data that underpins this section (USDA FDC entries 169451, 168625, 169449, 169454, 169452):

*CoQ10 from Pravst et al. (2010) [5] — not tracked in standard USDA nutrient panel.

What the table makes explicit:

Spleen has zero detectable vitamin A. A single-organ spleen supplement cannot deliver vitamin A in any meaningful quantity. If you take a standalone spleen product for its iron density, you are not receiving the vitamin A that a liver-containing blend provides. The NM and AW formulas address this directly — their liver components supply vitamin A; their spleen components amplify iron beyond what liver alone could deliver.

Liver is a moderate iron source relative to spleen. Liver's 4.9 mg/100g is substantive, but spleen's 44.6 mg/100g is in a different category entirely — nearly ten times the concentration. Multi-organ blends that include both get iron density that neither single-organ product could replicate on its own.

Heart is the only meaningful natural source of CoQ10. No plant food, and no other organ, delivers CoQ10 at the concentration of raw beef heart (~11 mg/100g). A blend without heart simply does not carry CoQ10 in any meaningful amount.

Kidney delivers nearly half the selenium in a five-organ formula. Single-organ liver products contribute selenium at much lower density. If selenium is a priority — relevant for thyroid health, antioxidant enzyme function, and regions with selenium-depleted soils — a kidney-containing blend addresses a gap that liver alone cannot.

Pancreas is the only contributor of naturally occurring digestive enzymes. No other organ in the standard supplement range contains these enzyme proteins in concentrated form.

The practical conclusion: a single-organ supplement gives you what that organ has — and explicitly does not give you what the other four organs would have provided. Multi-organ blends are built on the direct consequence of this nutrient data. They are not more of the same thing. They are different things — nutritionally non-overlapping profiles assembled into a more complete whole-food package.

For the full per-serve calculated breakdown of Nature's Multi — with per-component USDA attribution and dominant-contributor percentages — see Nature's Multi FAQ Q3.

Ancestral Woman: the iron-dense blend with a unique addition

Ancestral Woman takes the blend logic further by combining the three richest heme-iron sources in any food — beef liver, beef spleen, and whole blood — in a single formula. At 15% spleen (providing the densest iron concentration per gram of any organ) and 10% whole blood (a gram-for-gram heme iron source rarely available from mass-manufacturer supply chains), Ancestral Woman provides approximately 6–10 mg of heme iron per serving [9] — far greater than any product that relies on liver alone.

The fourth differentiator for AW is reproductive organ tissue (ovary, uterus, fallopian tubes — 40% of the formula). No competitor blend in the Australian market includes all three reproductive organs alongside three heme-iron sources. This is a supply chain story: Vital Origin sources through Provenir, Australia's only on-farm, high-welfare processor. Whole blood and reproductive organs require on-farm processing to source at supplement quality. Mass-manufacturer-dependent brands cannot access them.

Choosing Between Single-Organ and Blended Products {#choosing}

The choice is not single-organ versus blended as a quality distinction. Both have clear use cases.

When a single-organ product makes sense

Beef Liver Capsules are the right choice when vitamin A and copper are the priority. No blend delivers these at the concentration that a dedicated liver product does — because blends dilute the liver component across multiple organs. At full daily serving, Beef Liver Capsules provide approximately 745 µg RAE of vitamin A (~106% of adult women's RDI) and ~1.5 mg of copper (~122% RDI). Nature's Multi, at 20% liver, delivers approximately 160 µg RAE and ~0.31 mg copper. The dilution is real and intentional — NM trades vitamin A density for broader spectrum coverage. If vitamin A specifically is your nutritional focus, single-organ liver is the more targeted tool.

Beef Heart Capsules are the right choice when CoQ10 is the focus, or when stacking onto a liver or blend protocol to add the heart-specific nutrients (taurine, carnitine, higher B12) without vitamin A overlap. Heart contains zero vitamin A — it adds to a protocol without adding to the fat-soluble vitamin load.

Beef Kidney Capsules are the right choice for targeted selenium density or for the DAO angle. Kidney at full 6-cap serving delivers approximately 21 µg of selenium (~35% of adult RDI) — a more concentrated kidney contribution than any blend at 20% kidney content. Buyers who want kidney's specific profile in a higher daily dose are better served by the standalone product, with or without stacking on a blend.

When a blend makes sense

Nature's Multi is the broadest-spectrum option in the range — suited to anyone who wants a genuine whole-food multi-organ protocol in a single daily product. It is the natural starting point for new customers who are not yet sure which single organ addresses their primary nutritional gap. It covers CoQ10 (heart), iron (spleen as dominant contributor), vitamin A (liver), selenium (kidney), DAO (kidney), and digestive enzymes (pancreas) in one serving.

Ancestral Woman is the iron-density product — built specifically for women whose nutritional priority is heme iron from multiple whole-food sources. Its formula (liver, spleen, whole blood, reproductive organs, kidney) is purpose-built for that outcome in a way that no broad-spectrum blend replicates.

Stacking logic

Beef Liver + Nature's Multi: compatible and not redundant. NM includes liver at 20% — a moderate broad-context serving. Adding dedicated Beef Liver Capsules raises the vitamin A and copper contribution substantially. Combined daily vitamin A at full serving of both is approximately 895 µg RAE — approximately 30% of the adult NHMRC UL of 3,000 µg/day [2], well within safe ranges for most healthy adults. Worth noting if you also use cod liver oil or separate vitamin A supplements.

Beef Heart or Beef Kidney + Nature's Multi: increases the concentration of those organs' specific nutrients above the 20% blend contribution. A reasonable approach if CoQ10 (heart) or selenium/DAO (kidney) is a higher priority alongside the broader multi-organ base.

Beef Organ Bundle (Liver + Heart + Kidney): covers the three most established single-organ use cases in one purchase. Does not include spleen or pancreas — for those, Nature's Multi is the complement.

For the complete stacking guide, see Nature's Multi FAQ Q15 and the Beef Kidney FAQ Q15.

What to Look for in a Quality Organ Supplement {#quality-checklist}

Not all organ supplements are equivalent. The nutrient data above reflects high-quality raw whole-food organ tissue. What reaches that standard in a finished supplement product depends on several processing and sourcing decisions that vary considerably across the market.

100% grass-fed and grass-finished

Grass-fed means the animal grazed on pasture for some or all of its life. Grass-finished means it was on pasture for the entirety of its life — no grain finishing in a feedlot at the end. This distinction matters for the fatty acid profile of the organ tissue: grass-finished cattle have more favourable omega-3 to omega-6 ratios and different fat-soluble vitamin concentrations than grain-finished counterparts.

Many products that say "grass-fed" are not grass-finished. Vital Origin specifies both — 100% grass-fed and grass-finished, verified through Provenir traceability.

On-farm processing

Provenir is Australia's only on-farm, high-welfare processor. Processing happens at the farm rather than at a remote industrial facility — reducing animal transport stress, improving traceability, and shortening the handling chain between slaughter and freeze-drying. For enzyme-containing organs like kidney (DAO) and pancreas, shorter time to processing improves enzyme preservation. For whole blood — included in Ancestral Woman — on-farm processing is not a preference but a requirement: whole blood cannot be sourced at supplement quality through standard industrial supply chains.

Most organ supplement brands — including some well-known international names — source raw materials through large-scale manufacturers who aggregate from multiple farms. Provenir is a meaningful structural difference, not a marketing claim.

Raw freeze-dried, not heat-desiccated

The processing method determines how much of the raw tissue's nutritional profile survives into the finished capsule. Raw freeze-drying (lyophilisation) removes moisture at low temperatures by freezing the tissue and reducing surrounding pressure so frozen water sublimates directly from solid to gas. Heat-sensitive nutrients — B vitamins, CoQ10, vitamin A, and naturally occurring enzymes — are better preserved through this process.

Heat-based desiccation involves applying elevated temperatures to remove moisture. For most stable nutrients the difference is modest; for heat-sensitive compounds and enzymes, it is more significant.

Single-ingredient capsules — no fillers or flow agents

Some organ supplement manufacturers add magnesium stearate, rice flour, maltodextrin, or silicon dioxide to organ capsules — not for your benefit, but to aid their production process. Vital Origin capsules contain the organ ingredient and bovine gelatin capsule shell. Nothing else.

Australian sourcing, glass or recyclable tin packaging

All Vital Origin organ supplements come from Australian cattle. The tallow range uses glass jars — appropriate for cooking fat where plastic poses risks at high temperatures. The organ capsule range uses recyclable metal tins — more sustainable than glass on freight emissions and without glass breakage risk.

Free from GMOs, hormones, antibiotics, Bovaer, and mRNA interventions.

Frequently Asked Questions {#faq}

Schema note for IT: FAQPage JSON-LD block. 8 Q&A pairs below. Each maps to a Question/Answer node. Implement per the same pattern as PDP FAQ blocks.

Q: Are beef organ supplements safe to take every day?

For most healthy adults, daily use is appropriate and consistent with how traditional cultures consumed organ meats — regularly and as a matter of course, not as an occasional addition. The main nutrient to be mindful of with daily liver use is vitamin A, which is fat-soluble and accumulates in the body. At standard servings of Vital Origin products, vitamin A intake sits comfortably within the NHMRC adult Tolerable Upper Intake Level of 3,000 µg RAE/day [2]. Avoid combining liver products with separate high-dose vitamin A supplements or cod liver oil. If you have a pre-existing health condition, are pregnant, or are taking prescribed medications, consult your healthcare practitioner.

Q: Do organ supplement capsules taste like organ meat?

No. The freeze-drying process and capsule encapsulation together mean there is no detectable taste or smell when taking the capsules. You can take them with water like any other supplement. This is one of the main reasons people choose the capsule format — particularly for kidney and spleen, which have distinctive flavours when cooked.

Q: How long until I notice a difference?

Organ supplements are food, not pharmaceuticals. Results from food-based nutrition are cumulative and individual — they depend on your starting nutritional status, diet, consistency of use, and what nutrient gaps you are addressing. Most people who take organ supplements consistently describe noticing changes over weeks, not days. Consistency matters far more than timing or dose optimisation.

Q: Are beef organ supplements suitable for vegetarians or vegans?

No. All Vital Origin organ supplements are made from 100% grass-fed Australian beef organs. They are fully animal-based. The capsule shell is bovine gelatin. There is no plant-based equivalent of organ meat nutrition — the specific compounds (heme iron, preformed retinol, CoQ10, carnitine, taurine, DAO) are either absent from plant foods or present at a fraction of the concentration found in organ tissue.

Q: Can I take organ supplements alongside a synthetic multivitamin?

Yes, in most cases — but it is worth thinking through nutrient overlap. The most relevant consideration is vitamin A: if your synthetic multivitamin contains preformed retinol (listed as retinyl acetate or retinyl palmitate), and you are also taking Beef Liver Capsules at full dose, review the combined intake against the NHMRC adult UL of 3,000 µg RAE/day. At moderate intakes the overlap is unlikely to be a concern, but it is worth calculating for your specific products.

Q: Are organ supplements safe during pregnancy?

Please consult your healthcare practitioner before taking any organ supplement during pregnancy. The primary consideration is vitamin A: liver-containing products provide preformed retinol, and total vitamin A intake during pregnancy warrants attention (the NHMRC pregnancy UL is the same as the adult UL: 3,000 µg RAE/day [2]). Products that do not contain liver — such as standalone Beef Heart Capsules — do not carry a vitamin A consideration. Products with a reproductive organ component (Ancestral Woman) include a separate discussion around bovine reproductive tissue during pregnancy — see the Ancestral Woman FAQ Q6 for the full context.

Q: Are organ supplements safe for children?

Consult your healthcare practitioner before giving organ supplements to children. Children's nutrient requirements and Tolerable Upper Intake Levels differ from adults — particularly for fat-soluble vitamins like vitamin A [2]. Organ meats have historically been part of children's diets in traditional cultures, but the concentrated capsule format differs from eating whole food, and a practitioner familiar with your child's diet and health is the right person to advise.

Q: How should I store organ supplement capsules?

Store in a cool, dry place away from direct sunlight and heat. Do not refrigerate unless the label specifies this — condensation from refrigeration can degrade the product. Each tin has a 2-year shelf life from the manufacturing date. Keep the lid sealed when not in use.

Where to Start with Vital Origin {#where-to-start}

The right entry point depends on your primary nutritional focus:

If heme iron is the priority — particularly for women with elevated iron requirements, menstruating women, or postpartum recovery — start with Ancestral Woman. It combines liver, spleen, and whole blood for heme iron from three distinct whole-food sources, delivering approximately 6–10 mg of heme iron per serving. No other product in the AU market includes whole blood.

If you want broad whole-food multi-organ coverage — the nearest equivalent to a whole-food multivitamin — start with Nature's Multi. Five organs (liver, heart, kidney, spleen, pancreas) in one daily serving. The broadest-spectrum product in the range.

If vitamin A, copper, and B12 are the focus — or if you want to start with the hero single-organ product — start with Beef Liver Capsules. The most nutrient-dense food in the human food supply, by any reasonable metric.

If CoQ10, taurine, and carnitine are the focus — or if you want to build on a liver or blend protocol — add Beef Heart Capsules.

If selenium density or the DAO angle is the focus — Beef Kidney Capsules are the most targeted single-organ option for that outcome.

For an all-in-one stack — the Beef Organ Bundle (Liver + Heart + Kidney) covers the three most established single-organ use cases in one purchase. The Animal-Based Fuel Bundle (Liver + Heart + Tallow) adds cooking fat to the capsule protocol.

About Vital Origin {#about}

Vital Origin is an Australian brand making 100% grass-fed beef organ supplements and tallow. Founded on the principle that the most nutrient-dense foods in the human food supply are the organs our great-grandparents ate without thinking — and that modern convenience should not require abandoning that.

Every Vital Origin product is sourced from 100% grass-fed and grass-finished Australian cattle, processed through Provenir (Australia's only on-farm, high-welfare processor), and raw freeze-dried with no fillers, flow agents, or synthetic additions. The capsule shell is bovine gelatin. The packaging is recyclable tin (capsules) or glass (tallow). Nothing hidden; nothing synthetic.
