Tag: Menadione risks

According to extensive research dating back to the 1980s and 1990s, the synthetic vitamin K3 (menadione) is toxic and harmful to humans. This starkly contrasts with the natural forms, vitamin K1 and K2, which are not associated with toxicity in humans, even at high doses.

Research from the 1980s and 1990s showed that Vitamin K3 (menadione), a synthetic form of Vitamin K, is harmful to humans, causing liver damage and the destruction of red blood cells. Given these dangers, it is critical to understand precisely **what does K3 do to the body?** and why it is not an acceptable dietary supplement for people.
