Hmm how much k2 is too much? Would .5mg per day be beneficial enough for aspirin? Im trying to not lower my estrogen too much because of crackling joints and tiredness.
Peat said 1mg vitamin K can offset the bleeding risks of 325mg aspirin. I don't think there is an upper (NOAEL) dose discovered for vitamin K2. The studies with rats showed that even a HED did no harm and the organs kept gobbling up the vitamin K, which shows the body likes to get as much as it can. However, like anything else it can probably cause imbalance in the sense that it could increase the need for vitamin A, and D. So, I think for long term preventive use maybe 1mg-2mg daily are OK, especially when taken with aspirin.
