For ANYONE with bad circulation in legs ....(i have very bad vericose veins that are very painful if i dont take anything...) i HIGHLY recommend vitamin k1 and k2. =) I used to have to take 2 capsules of an herbal vein supplement containing diosmin, horse chestnut extract, which was pricy. But with 1 vitamin k capsule im good. vitamin k is important for everyone anyway and people are just realizing its so important for bones, etc.
