HelloPharmacist Scorecard of Liver Beef Natural Glandular by Allergy Research Group

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
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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Liver Beef Natural Glandular contains one active ingredient: liver extract, a concentrated form of beef liver tissue. That's it for the active part.

The capsule also holds several inactive ingredients — hydroxypropyl methylcellulose, microcrystalline cellulose, rice hull concentrate, gum arabic, and sunflower oil — which are there to bind and deliver the active ingredient.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Liver Extract product and its label doesn't state a use — see Liver Extract's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for liver extract is thin. For chronic fatigue syndrome, it's rated possibly ineffective — meaning the studies we have don't show it works for that.

For hepatitis C, we simply don't have enough reliable evidence to say whether it helps or doesn't. If you're considering this for either condition, the data we hold won't back up a strong claim.

The evidence, ingredient by ingredient 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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

No adverse reactions have been reported from liver extract itself. That said, a full safety workup hasn't been done, so there are gaps in what we know.

The bigger caution is that liver products can deliver very high levels of vitamin A and iron — both of which can be harmful at high levels, especially if you're pregnant or taking other supplements with those nutrients. There's also a theoretical concern about contamination.

Liver extract comes from raw animal liver from slaughterhouses, and there's a small risk of contamination from sick or diseased animals. Cows in certain countries — including Great Britain, France, The Netherlands, Portugal, Luxembourg, Ireland, Switzerland, Oman, and Belgium — have had bovine spongiform encephalopathy (BSE), a serious brain disease.

While no human BSE cases have been linked to liver extract products to date, until we know more, products sourced from those countries carry that worry.

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Liver Extract.
  • The most serious interaction on file is rated Minor.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 3 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.

Check with your pharmacist before using this product if you take warfarin (Coumadin) — a blood thinner — or iron-containing medications or supplements. The liver extract can interfere with warfarin's effectiveness and add to your iron intake.

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 single-ingredient glandular product with very little evidence it works for the conditions it's marketed for. If you take warfarin or iron supplements, you'll need to talk with your doctor or pharmacist first.

The vitamin A and iron content, plus source-quality concerns, mean it's not a no-brainer for most people. Before you start, check your medications and chat with us.

Liver2 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.

Liver Beef Natural Glandular by Allergy Research Group: Common Questions

Does Liver Beef Natural Glandular by Allergy Research Group interact with any medications?
Yes. Based on its ingredients, Liver Beef Natural Glandular has a known interaction with 3 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Liver Beef Natural Glandular contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm pregnant?
Liver products can carry very high vitamin A, which may harm a developing baby. The data on file doesn't tell us the product is safe in pregnancy. Talk with your doctor before using — don't start it on your own.
Will this help my chronic fatigue?
The evidence doesn't support it. Liver extract is rated possibly ineffective for chronic fatigue syndrome, so there's no solid reason to expect it to help.
What exactly is in this?
One active ingredient: beef liver extract. The rest is the capsule and inactive fillers — things like microcrystalline cellulose and gum arabic that hold it together.
Are there any reported side effects?
No adverse reactions have been formally reported, but a thorough safety study hasn't been done. The main concern is the high vitamin A and iron content, plus the risk of contamination from raw liver tissue sourced from slaughterhouses.
Where does the liver come from?
The product facts don't specify the sourcing. That matters because liver from certain countries carries a theoretical BSE risk. Ask the manufacturer directly where their beef is sourced before you buy.
Can I take this with my iron supplement?
Not without checking first. Liver extract contains iron, so adding it to an iron pill could push your total intake too high — especially over time or at high doses. Talk with your pharmacist to make sure it's safe for you.
