Ancestral Supplements is a real company that sells freeze-dried organ meat capsules sourced from New Zealand grass-fed cattle. Whether it’s “legit” depends on what you’re asking: the products contain real ingredients and the sourcing standards are verifiable, but the brand carries significant baggage from its founder’s steroid scandal, and it lacks the independent third-party certifications that set top-tier supplement brands apart.
What the Company Actually Sells
Ancestral Supplements produces capsules filled with freeze-dried organs and tissues from cattle, including liver, bone marrow, thymus, and others. The idea is simple: ancestral humans ate the whole animal, organs included, and these capsules offer a convenient way to get those nutrients without cooking liver yourself. Freeze-drying is the processing method, which preserves the nutrient profile and biological activity of the raw tissue better than heat-based drying.
The product labels, confirmed through the NIH’s Dietary Supplement Label Database, state that the ingredients are sourced from New Zealand, from cattle that are grass-fed, grass-finished, and raised without hormones, pesticides, or antibiotics. New Zealand does maintain one of the strictest livestock biosecurity systems in the world, with government licensing, auditing, and certification for animal products. That sourcing claim is a genuine point in the brand’s favor. The company also states its products contain no fillers or flow agents, meaning no magnesium stearate, silica, or other common inactive additives that many supplement brands use to speed up manufacturing.
The Liver King Controversy
The elephant in the room is Brian Johnson, better known as “Liver King,” who founded and promoted Ancestral Supplements. Johnson built a massive social media following by showcasing his muscular physique and attributing it to eating raw organs, intense outdoor workouts, and following what he called the nine “Ancestral Tenets.” He positioned himself as living proof that the ancestral lifestyle, and by extension his supplement line, could transform your body.
In 2022, leaked emails revealed Johnson had been spending roughly $11,000 per month on anabolic steroids. The physique he credited to raw liver and primal living was largely pharmaceutical. A class action lawsuit followed, accusing Johnson and his companies (Ancestral Supplements and The Fittest Ever LLC) of orchestrating what the suit called a “cult-like, extreme and implausible regimented lifestyle” designed to funnel followers toward buying his products. The lawsuit argued that customers purchased and repurchased supplements specifically because they believed Johnson’s body was proof the products worked, and that the steroid revelation demonstrated “the ineffectiveness of the Ancestral Tenets, namely the Eat Tenet.”
This doesn’t necessarily mean the supplements themselves are fake or dangerous. Beef liver capsules contain real nutrients regardless of who sells them. But it does mean the brand’s most visible marketing claims were built on a lie, which is a legitimate reason to question the company’s honesty more broadly.
Third-Party Testing Is the Missing Piece
One of the clearest ways to evaluate any supplement brand is whether its products carry independent third-party certifications. The gold standard is NSF International certification, which tests supplements against the only American National Standard for dietary supplement ingredients (NSF/ANSI 173). NSF conducts testing in its own accredited labs to confirm that what’s on the label matches what’s in the bottle, and screens for over 280 banned substances including steroids, stimulants, and undeclared ingredients.
Ancestral Supplements does not appear to carry NSF certification, nor does it display Informed Sport, USP, or other widely recognized third-party seals. The company references New Zealand’s government inspection systems for its raw materials, which is meaningful for sourcing quality, but that’s not the same as having the finished capsules independently verified for potency, purity, and label accuracy. Without third-party testing, you’re relying on the company’s own claims about what’s in each capsule and how much.
Do Organ Meat Supplements Actually Work?
Organ meats are genuinely nutrient-dense foods. Beef liver, for example, is one of the richest natural sources of vitamin A, B12, iron, and copper. Bone marrow contains collagen, fatty acids, and minerals. The nutritional value of these tissues isn’t in dispute.
The real question is whether freeze-dried capsules deliver meaningful amounts of those nutrients compared to simply eating organ meats or taking standard vitamin supplements. Most organ capsule products provide relatively small servings (a few grams of dried tissue per daily dose), which is far less than eating a serving of liver with dinner. They can help fill gaps if you’d never otherwise eat organs, but they’re not a replacement for a balanced diet and shouldn’t be expected to produce dramatic physical transformations on their own.
Vitamin A Toxicity Risk With Liver Capsules
One practical safety concern with liver-based supplements is vitamin A. Beef liver is extremely high in preformed vitamin A, and unlike the plant-based form (beta-carotene), preformed vitamin A from animal sources can accumulate to toxic levels. The tolerable upper intake for adults is 3,000 micrograms RAE per day. Chronic toxicity develops when intake regularly exceeds about 8,000 micrograms RAE per day over time, causing symptoms like headaches, nausea, blurred vision, joint pain, and in severe cases, liver damage.
If you’re taking liver capsules alongside a diet that already includes eggs, butter, fortified foods, or a multivitamin with vitamin A, the total can add up. This isn’t unique to Ancestral Supplements. It applies to any concentrated liver product. But it’s worth calculating your total daily intake, especially if you’re taking multiple organ-based supplements simultaneously or giving them to children, who have lower toxicity thresholds.
The Bottom Line on Legitimacy
Ancestral Supplements sells real organ meat products from a reputable sourcing region, uses a clean ingredient list without common fillers, and provides a product category (freeze-dried organs) that has genuine nutritional value. On those basic measures, it’s a legitimate product.
Where the brand falls short is trust. Its founder built the company’s reputation on fraudulent personal claims, it faces class action litigation over those marketing practices, and its products lack the independent third-party certifications that would let you verify quality without relying on the company’s word. If you want organ meat capsules, the products likely contain what they say they do, but you’d be making that purchase on faith rather than verified evidence. Competitors that carry NSF or USP certification offer a higher level of accountability for roughly the same type of product.
