Re: Cured of hepatitis C

The plant-based source of vitamin K (K1, or phylloquinone) seems to have no toxic effects in most any reasonable dose. But the synthetic form (K3, or menadione) has caused some liver toxicity and, rarely, a form of anaemia when taken in high doses. Theres also K2 (or menaquinones), but K1 and K2 are fine. As usual, it seems best to avoid synthetic forms, if possible. If the individual is on coumadin (blood thinner), he needs to talk with his doctor, as vitamin K can interfere with its effect.
