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.
What’s inside
Full disclosure
Perfect Desiccated Liver contains one active ingredient: beef liver that's been dried and powdered. That's it — no other active ingredients.
The inactive ingredient list is empty, so there are no fillers or binders added.
Does it work?
Couldn't assess
The evidence on desiccated liver for chronic fatigue syndrome (CFS) is rated possibly ineffective in our data. For hepatitis C, there isn't enough reliable evidence to rate it one way or the other.
If you're considering this product for either condition, the science doesn't support a strong case yet.
How safe is it?
Well-documented data
No adverse reactions have been reported, though a thorough safety evaluation hasn't been done. The main concerns are that desiccated liver can deliver very high levels of vitamin A and iron — both of which matter if you take it regularly or in large amounts.
There's also a theoretical concern about contamination, since liver is sourced from slaughterhouses and may come from sick or diseased animals. Countries where bovine spongiform encephalopathy (BSE, also called mad cow disease) has been reported include Great Britain, France, The Netherlands, Portugal, Luxembourg, Ireland, Switzerland, Oman, and Belgium.
No cases of BSE transmission to humans from liver extract have been reported, but it's a quality issue to keep in mind. For pregnancy, the high vitamin A content may harm a developing baby, so avoid it unless your doctor advises otherwise.
Safety during breastfeeding hasn't been well studied — talk with your doctor before using.
Meds to double-check
Minor interactions only
If you take warfarin (a blood thinner), check with your pharmacist before adding this product — the vitamin K content could theoretically affect how well it works. If you take iron supplements or iron-containing medications, be aware that combining them with this product may increase your total iron intake and raise the risk of stomach problems or iron overload.
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 a whole-food supplement with minimal processing and no fillers. If you take warfarin or iron supplements, or if you're pregnant, you'll want to talk with your pharmacist or doctor first.
For other people, the main thing is source quality — make sure you know where the liver came from and that it's from a reputable manufacturer.

Perfect Desiccated Liver by Perfect Supplements Drug Interactions
HelloPharmacist Interaction Report
Perfect Desiccated Liver by Perfect Supplements is a single-ingredient beef liver powder with documented interactions affecting three individual medications.
The most serious concern is warfarin (a blood thinner). Liver extract contains small, variable amounts of vitamin K, which theoretically could reduce warfarin's effect and lower your INR if you start, stop, or substantially change how much you take.
That said, this interaction hasn't been directly studied or reported in humans, so the real-world risk is unclear.
Read the full breakdown — every affected drug type, severity by severity
There's also a Minor interaction with iron supplements or iron-containing medications. Because liver extract contains heme iron (an absorbable form), combining it with iron products may raise your total iron intake and increase the risk of stomach upset or iron buildup.
The risk is higher with large doses, long-term use, or if you have a condition that makes your body store too much iron (hemochromatosis).
If you take warfarin or iron supplements, check your exact medications with the search tool on this page before you start.

Beef Liver, Desiccated, Powder
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.
