HelloPharmacist Scorecard of Perfect Desiccated Liver by Perfect 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.

From our pharmacy team — supplement deep dive

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.

Perfect Desiccated Liver is a single-ingredient supplement: desiccated beef liver powder—freeze-dried and powdered liver from cattle. The capsule itself is made from vegetable material and contains no other active ingredients.

Desiccated liver is meant to deliver the nutrient profile of whole liver in concentrated form.

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 we hold does not establish that desiccated liver works for chronic fatigue syndrome—the data rates it possibly ineffective for that use. For hepatitis C, there is insufficient reliable evidence to rate whether it helps.

If you're considering this supplement for a specific health concern, talk with your pharmacist or doctor about what the current evidence actually shows for your situation.

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 in the safety data we hold, but a thorough evaluation of safety outcomes has not been conducted. The bigger concern is the source: beef liver can contain very high levels of vitamin A and iron.

Vitamin A at high levels may harm a developing baby, so pregnant people should avoid this product unless their doctor advises otherwise. There is also a theoretical risk of contamination, since liver is sourced from slaughterhouses and could come from sick or diseased animals.

Countries where bovine spongiform encephalitis (BSE, also called mad cow disease) has been reported include Great Britain, France, The Netherlands, Portugal, Luxembourg, Ireland, Switzerland, Oman, and Belgium; however, no cases of BSE transfer to humans from liver extract products have been documented. Until more is known, check the country of origin with the manufacturer.

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.

If you take warfarin (Coumadin) or iron-containing medications or supplements, check them with the tool on this page before adding this product. The minor interactions with warfarin and iron are documented but have not been directly studied in humans.

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.

Desiccated liver is generally low-risk for healthy adults eating food amounts, but this supplement can deliver high doses of vitamin A and iron. If you take warfarin or iron supplements, or if you're pregnant, breastfeeding, or have an iron-overload condition, talk with your pharmacist before starting.

Verify the product's country of origin if BSE contamination is a concern for you.

Desiccated 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.

Perfect Desiccated Liver by Perfect Supplements: Common Questions

Does Perfect Desiccated Liver by Perfect Supplements interact with any medications?
Yes. Based on its ingredients, Perfect Desiccated Liver 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?
Perfect Desiccated Liver 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.
Is desiccated liver safe during pregnancy?
Liver products can contain very high vitamin A, which may harm a developing baby. The safety data we hold advises against use in pregnancy unless your doctor advises otherwise. Talk with your doctor or pharmacist before taking this if you're pregnant or planning to become pregnant.
Does this product actually work for chronic fatigue?
The evidence we hold rates desiccated liver possibly ineffective for chronic fatigue syndrome. That means the studies don't support its use for that purpose. If you're considering it for fatigue, ask your pharmacist or doctor what evidence-based options exist.
What exactly is desiccated liver?
It's freeze-dried and powdered beef liver—whole liver tissue that's had the water removed and been concentrated into powder form, so you're getting liver nutrients in a capsule.
Could this product have BSE (mad cow disease) contamination?
BSE has been reported in cattle in several countries, including Great Britain and France. There have been no documented cases of BSE transfer to humans from liver extract products, but until more is known, check where this product's beef liver came from—ask the manufacturer or look at the label.
What if I'm already taking iron supplements?
Liver extract contains heme iron, the form your body absorbs well. Taking it with iron supplements could increase your total iron intake and raise the risk of stomach upset or iron buildup—especially at high doses or with long-term use. Check with your pharmacist before combining them.
