Beef Liver Capsules: My Honest Review of Ancestral Supplements
I have always believed real food is the best source of nutrition. A whole-food, animal-based, nutrient-dense way of eating has been the foundation of how I live for years now. But even before I understood anything about nutrition, I was never someone who trusted supplements. I would look at those bottles on a shelf and wonder what was actually inside the capsule.
That has not changed much. I still question most supplements and avoid them unless there is a clear reason to use one. When people ask my opinion, I tell them the same thing every time. If you are going to take a supplement, make sure it is third-party tested for heavy metals, ingredient purity, and proof that it actually delivers what it claims.
So it surprised even me when I decided to try beef liver capsules from Ancestral Supplements. I have tried eating liver more times than I can count. The texture defeats me every time, no matter how I cook it or what I pair it with. But I also know how nutritionally dense liver is, and I did not want to miss out on what it offers just because I cannot get past the taste.
How I found the brand
I came across Ancestral Supplements through Dr. Ken Berry, a board-certified family physician who has built a strong following in the keto, carnivore, and ancestral health space for questioning outdated medical advice and helping people take a more active role in their own health. He is the author of Lies My Doctor Told Me and shares practical, no-nonsense health information through his YouTube channel. Dr. Berry did not found Ancestral Supplements, but he recommends their products often, specifically as a way to get the benefits of organ meats for people who will never eat them regularly. That recommendation is how I found the brand in the first place.
What actually got past my skepticism
Before I tried anything, I checked their testing standards, because that's the only thing that gets a supplement past my skepticism. Ancestral Supplements independently tests for heavy metals including lead, arsenic, mercury, and cadmium. They test for microbial contamination from bacteria, mold, and yeast. They verify the ingredient itself, confirming it's genuinely beef liver rather than a diluted filler blend, and they test for pesticide and herbicide residue as well. The cattle are grass-fed and pasture-raised in New Zealand, and the liver is freeze-dried rather than heat-processed, which preserves nutrients that heat tends to destroy. No fillers, no additives.
Why beef liver earns its reputation
Beef liver earns its reputation as nature's multivitamin honestly. It carries meaningful amounts of vitamin A for immune function, vision, and skin health. It's rich in B vitamins that support energy production, mood, and brain function. The iron in liver is heme iron, the form your body absorbs most efficiently, which matters far more than the iron content of any plant source. It supplies zinc, copper, and selenium, three minerals that quietly run your hormone production, metabolism, and immune response in the background. It also contains choline, which your brain and liver both depend on, and CoQ10, which supports cellular energy production and heart function. There's a reason people who eat organ meats regularly rarely have to think about micronutrient gaps.
What I actually noticed
I started with two capsules in the morning, taken with water. I did not expect much. A few days in, I noticed a real shift. My energy felt steadier through the day, my mood was more even, and I started sleeping deeper than I had in a while. I cannot say with certainty that the capsules alone caused this, since I've also been eating more animal fat and protein lately. It's probably the combination. But the shift was real enough that I noticed it without looking for it.
I'm curious enough now to try the other organ supplements in their line. Heart, kidney, maybe even spleen eventually.
Where I land on this
I still believe food comes first, completely and without exception. But if I had to recommend one supplement, this is the one. It's clean, it does what it says, and the testing behind it is something I can actually verify rather than take on faith. If you want what liver offers but cannot get past eating it, this is a reasonable way to close that gap. Whatever you choose to take, check for transparency and third-party testing first. Your health isn't something to gamble on a mystery capsule.
Frequently Asked Questions
What does third-party testing actually verify in a supplement like this? Independent testing confirms the product is free of heavy metals like lead and arsenic, checks for microbial contamination, verifies the ingredient is genuinely what the label claims rather than a diluted filler, and screens for pesticide and herbicide residue.
Why is beef liver's iron better than iron from plant sources? Beef liver provides heme iron, the form your body absorbs most efficiently. Plant sources provide non-heme iron, which your body absorbs at a much lower rate, especially when compounds like phytates are also present.
Is freeze-drying better than other processing methods for organ supplements? Freeze-drying removes moisture without applying heat, which helps preserve nutrients like B vitamins and CoQ10 that tend to degrade under heat processing.
How much beef liver supplement should I start with? Starting with a lower dose, such as one to two capsules, and adjusting based on how you feel is a reasonable approach. Anyone pregnant, breastfeeding, or managing a liver condition should check with a doctor first given liver's concentrated vitamin A content.
