Desiccated organ supplements

What the evidence says

Liver is a legitimately extraordinary source of vitamin A, B12, copper, iron and folate, and freeze-drying preserves much of that — so as a whole-food nutrient source the premise holds. What has no controlled evidence is the "like supports like" claim underneath organ-specific products: that taking desiccated heart, kidney or testicle supports your own. That idea is traditional, not tested.

What studies used

Published human trials have not established a dose or a clinical benefit. Published studies had not established a preferred timing.

Reported from published studies and product labelling — a record of what was used in research, not a recommendation. What is right for you is a conversation with a clinician.

Watch out for

• Vitamin A from liver is preformed retinol and accumulates — combining several organ products, or adding a multivitamin, can approach toxic intakes over time
• Copper and iron also accumulate; this is not a supplement to stack casually
• Sourcing and pathogen control matter more here than in almost any other supplement category
