Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This formula has two active ingredients: whey protein concentrate and beef liver powder. Whey protein is a milk-derived protein used to support muscle and athletic performance.

Beef liver powder is included for its nutrient density. The product also contains several inactive ingredients — stearic acid, calcium carbonate, microcrystalline cellulose, croscarmellose sodium, hydroxypropyl methylcellulose, magnesium stearate, and silicon dioxide — which are common tablet binders and fillers.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: liver support and amino acid supplementation.
  • We looked for evidence on: Hepatitis, Nonalcoholic steatohepatitis (NASH), Liver function, Liver detoxification.
  • The closest evidence on file: Whey Protein is rated "Insufficient Reliable Evidence To Rate" for Hepatitis (Natural Medicines).
  • Also on file: Whey Protein is rated "Insufficient Reliable Evidence To Rate" for Nonalcoholic steatohepatitis (NASH).
  • Also on file: Liver Extract is rated "Insufficient Reliable Evidence To Rate" for Hepatitis C.

Whey protein is possibly effective for athletic performance based on available evidence. For other uses listed in our data — osteoporosis, COPD, age-related cognitive decline, and HIV/AIDS-related wasting — either the evidence suggests it's possibly ineffective (osteoporosis and COPD) or there isn't enough reliable data to rate it (cognitive decline and wasting).

We don't have effectiveness data on file for beef liver powder.

The evidence, ingredient by ingredient Whey Protein Liver Extract

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Whey protein is generally well tolerated by healthy adults when used as directed, though concentrated supplement products haven't been studied as thoroughly as whey in food. Most common side effects are dose-related and include acne, bloating, cramps, diarrhea, fatigue, headache, nausea, acid reflux, reduced appetite, and thirst.

Whey protein has been linked to the onset or worsening of acne in case reports; acne typically cleared when people stopped taking it. Because high-dose whey supplements aren't well studied, check with your doctor first.

Pregnancy and lactation data for whey protein isn't on file — talk with your pharmacist or doctor for personalized guidance.

Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Whey Protein, Liver Extract.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; Parkinson's medications.
  • For scale: 56 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take levodopa (Sinemet) for Parkinson disease, check with your pharmacist — this is a Major interaction. Before starting, also verify your exact medications if you're on quinolone antibiotics (like ciprofloxacin), tetracycline antibiotics (like doxycycline), or bisphosphonates (like alendronate) — these are Moderate interactions where timing matters.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.

This product is designed for people looking to support athletic performance with whey protein and beef liver nutrients. If you take levodopa for Parkinson disease or use quinolone or tetracycline antibiotics, or bisphosphonates, this product isn't a good fit without talking to your pharmacist first.

Anyone with a history of acne should be aware that whey can trigger or worsen it.

Each ingredient & the kinds of drugs it affects

For each ingredient in Liver Amino Formula with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Whey Protein Concentrate4 drug types · 53 drugs

Levodopa

Theoretically, whey protein might decrease levodopa absorption.
Small clinical studies show that concomitant ingestion of protein or high doses of leucine or isoleucine (100 mg/kg) and levodopa can exacerbate tremor, rigidity, and the "on-off" syndrome in patients with Parkinson disease.

Likelihood Probable Evidence D
Bisphosphonates

Theoretically, whey protein might reduce the absorption of bisphosphonates.
Whey protein contains minerals such as calcium that bind bisphosphonates in the gut. Advise patients to take bisphosphonates at least 30 minutes before whey protein, but preferably at a different time of day.

Likelihood Probable Evidence D
Quinolone Antibiotics

Theoretically, whey protein might decrease quinolone absorption.
Whey protein contains minerals, such as calcium, that can bind to quinolones in the gut. To avoid this interaction, advise patients to take oral quinolones at least 2 hours before or 4-6 hours after whey protein.

Likelihood Probable Evidence D
Tetracycline Antibiotics

Theoretically, whey protein might decrease tetracycline absorption.
Whey protein contains minerals, such as calcium, that bind to tetracyclines in the gut. To avoid this interaction, advise patients to take oral tetracyclines at least 2 hours before or 4-6 hours after whey protein.

Likelihood Probable Evidence D
Whey Protein Concentrate full monograph & interactions

Beef Liver, Powder2 drug types · 3 drugs

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.

Likelihood Possible Evidence D
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.

Where does this information come from?

Will whey protein make my acne worse?

We don't have safety data on file for whey protein in pregnancy or lactation. Talk with your pharmacist or doctor — they can give you personalized advice based on your situation.
Can I take this with my antibiotics?
It depends on which antibiotic. Quinolone and tetracycline antibiotics bind to minerals in whey protein and won't be absorbed properly. Take them at least 2 hours before or 4–6 hours after this product. Check with your pharmacist about your specific antibiotic.
Does this help build muscle?
Whey protein is possibly effective for athletic performance. It's one of the most studied protein sources for supporting muscle with training, though results vary by individual.
