Does Fadogia affect liver or kidneys?
Yes, a recent study conducted by scientists from the University of Jos, Nigeria reported severe inflammation of kidneys and death of liver tissue (necrosis) based on 50 mg/kg, 100 mg/kg and 200 mg/kg of body weight after 40 days.
The animal study on Fadogia’s effect on the liver and kidney confirms the extent of the damage and was conducted as part of a toxicology and safety assessment published in the Scientific African in July 2023.

In the following sections, we shall deep-dive into the extent of the liver and kidney damage caused by Fadogia extract.
Effects of Fadogia on liver
The study showed that the albino rats treated with 50 mg/kg of Fadogia extract showed ballooning necrosis (death of tissue cells), while rats treated with 100 mg/kg extract showed massive tissue degeneration (necrosis), and rats treated with 200 mg/kg of the extract also showed further ballooning necrosis.
The study suggests strong evidence of the damaging side effects of Fadogia on liver at low dosages, causing death of body tissue in liver (i.e necrosis) which cannot be reversed.

Necrosis occurs when too little blood flows to the organ tissue and when large areas are affected, it is known as gangrene. This suggest long term use of Fadogia may cause gangrene, causing liver failure.
Effects of Fadogia on kidney
The same toxicology study conducted in July 2023 showed a massive presence of inflammation of cells in the kidneys of albino rats when treated with 50 mg/kg of Fadogia root extract. This confirms that Fadogia causes damage to the kidneys.
The effects of Fadogia Agrestis as higher dosage of 100 mg/kg also showed massive presence of inflammation red blood cells within the tissue and the reduction in interstitial spaces.

Yes, recent study using 50mg / kg of Fadogia showed strong evidence of degeneration and death of tissue cells in liver of albino rats after 40 days. This suggests long term consumption of Fadogia may cause further deterioration of liver function and possible liver failure.
Is Huberman recommended dosage of Fadogia safe?
Dr. Andrew Huberman’s recommendation of 400 mg of Fadogia Agrestis should not be viewed as safe as a recent study published in the Scientific African journal in 2023 reported that Fadogia caused massive inflammation of the kidneys and death of liver tissues at 50 mg/kg, 100 mg/kg and 200 mg/kg of Fadogia extract.
