What should I know about vitamin k3 was du wirklich wissen musst#gesundheitliche risiken von vitamin k3?

Vitamin K3 (menadione) is a synthetic form of vitamin K that is not approved for human supplementation in many countries due to well-documented health risks. Menadione can generate oxidative stress, leading to cellular damage. In newborns, high doses have been linked to hemolytic anemia and liver toxicity. In adults, excessive intake may cause liver damage and allergic reactions. The EU and US have banned menadione in dietary supplements; it is only used in animal feed or trace amounts in some multivitamins. MyBody-X does not offer a test for vitamin K3, as it is not recommended for human consumption. If you are considering a product containing K3, consult a physician first. The evidence for these risks comes from clinical observations and animal studies; the data are moderate but sufficient to advise against self-supplementation.
