As a supplement
Talk to your doctor or pharmacist.
Roll Call does not check drug interactions or assess personal safety.
A dried, powdered preparation made from animal kidney tissue, typically bovine, sold as a "glandular" supplement or as a nutrient-dense organ meat concentrate.
Why it’s used
Taken by some under the traditional glandular-supplement idea that eating an organ supports the corresponding organ in the body, and sometimes simply as a source of organ-meat nutrients such as B vitamins and minerals.
What the evidence says
There is no established clinical evidence that eating animal kidney tissue in supplement form affects human kidney function. Kidney tissue does supply nutrients found generally in organ meats, but supplement-specific dosing and effects have not been studied in controlled trials.
