我吃維生素B3時,都是把膠囊外殼給去除後吃下粉末, 這個品牌的粉末過於粗造,應該還再研磨的細小一些。

Bought for reducing cholesterol and blood thinners, take a month, I think the blood has become more liquid and it has reduced the pressure.

I feel like it is too early to tell but my circulation does seem better. I will let you know if my lab results came back within range.
