HelloPharmacist Scorecard of Grassfed Beef Eye by Ancestral Supplements
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product has 2 active ingredients: liver extract and eye. Liver extract is included for its nutrient profile, though the evidence for its effectiveness in specific conditions is limited or mixed.
We hold no interaction data for the eye component. The capsules also contain gelatin as an inactive ingredient.
Does it work?
Couldn't assess
The data we have on liver extract shows it is possibly ineffective for chronic fatigue syndrome (CFS). For hepatitis C, there isn't enough reliable evidence to know whether it works.
The evidence for eye as an ingredient is not established in the data we hold.
How safe is it?
Well-documented data
No adverse reactions have been formally reported, but a complete safety evaluation hasn't been done. Liver extract can deliver very high levels of vitamin A and iron, which is a concern if you take it long-term or in high amounts.
There's also concern about contamination: liver extract comes from raw animal liver sourced from slaughterhouses, potentially from sick or diseased animals. Products made from cows in countries where bovine spongiform encephalopathy (BSE, a brain disease in cattle) has been reported—including Great Britain, France, The Netherlands, Portugal, Luxembourg, Ireland, Switzerland, Oman, and Belgium—may carry a contamination risk, though no human cases from contaminated liver extract have been reported to date.
The safety data advises against use in pregnancy because of the high vitamin A content, which may harm a developing baby. We don't have pregnancy or breastfeeding safety information on file for the eye ingredient.
Meds to double-check
Minor interactions only
If you take warfarin (Coumadin) or iron supplements or medications, check with your pharmacist before using this product. The liver extract may affect how warfarin works and could increase iron levels in your body.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Only minor medication interactions are documented, and safety information is well characterized.
This is a whole-food supplement aimed at people interested in ancestral nutrition. If you take warfarin or iron supplements, talk with your pharmacist before starting it.
Anyone pregnant should avoid it unless their doctor approves. Check where the liver is sourced, and consider discussing the contamination risk and overall safety with your doctor first.

General Statements
For most of human history, we consumed the whole animal (nose-to-tail) with deep respect and profound purpose. For instance, Native Americans and early ancestral healers believed that eating the organs from a healthy animal would strengthen and support the health of the corresponding organ of the individual - also known as "like supports like." The traditional way of treating a person with a weak heart was to feed the person the heart of a healthy animal. Since we've abandoned these ways, the modern world has left us malnourished with an epidemic of declining health. The solution is to find ways to recreate our ancestral environment (sleep, nourishment, movement, sunshine, etc.). It's time we honor our ancestors by putting back in, what the modern world has left out (to return our people back to strength, health and happiness). We walk our talk and we offer a one-of-a-kind "guided" experience. Learn more at www.ancestralsupplements.com Brian Johnson "Liver King"

Grassfed Beef Eye by Ancestral Supplements Drug Interactions
HelloPharmacist Interaction Report
Grassfed Beef Eye by Ancestral Supplements contains liver extract, which has documented interactions with a small number of medications.
The main concern is warfarin (Coumadin), a blood thinner. Liver extract may contain variable amounts of vitamin K, which could theoretically reduce warfarin's effectiveness and lower your INR (a measure of how well the drug is working).
However, this interaction hasn't been directly studied in humans, so the real-world risk is unclear.
Read the full breakdown — every affected drug type, severity by severity
Liver extract can also contain heme iron. If you're taking iron supplements or iron-containing medications, combining them with this product might increase your total iron intake and raise the risk of stomach upset or iron buildup in your body—especially with high doses, long-term use, or if you have a condition like hemochromatosis (excess iron storage).
Altogether, these interactions span 3 individual medications.
The second ingredient, eye, was not checked—we hold no interaction data for it. Before you start this product, run your exact medications through the search tool on this page, especially if you take warfarin or iron supplements.

For each ingredient in Grassfed Beef Eye with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Liver
Iron
Liver extract can contain heme iron. Taking liver extract with iron-containing medications or supplements may increase total iron intake and could increase the risk of gastrointestinal adverse effects or excessive iron accumulation. The risk is greater with high doses, prolonged use, or in individuals with hemochromatosis or another iron-overload disorder. Review the iron content of the liver extract and the total elemental iron dose. Avoid unnecessary duplicate iron supplementation and consider monitoring ferritin and transferrin saturation when clinically appropriate.
Warfarin (Coumadin)
Liver extract products may contain small and variable amounts of vitamin K. Theoretically, starting, stopping, or substantially changing the amount of liver extract used could reduce the anticoagulant effect of warfarin and lower the INR. However, this interaction has not been directly studied or reported in humans, and the vitamin K content of liver extract products is generally not standardized. Consider monitoring the INR after a meaningful change in liver extract use.
