I have tried so many adaptogens and never really felt any support. I am pretty sensitive to ginsengs, especially Asian ginseng, so I thought I would try this one with American ginseng. American ginseng is usually milder. One capsule was too much for me to start with, I was getting a little amped up. So I dumped the capsule and divided it into 3 servings. So 1/3 capsule felt great, then I went up to 1/2 capsule and finally now I am at a whole capsule. This definitely works for me. If my adrenals are triggered and I take a capsule, I definitely notice a difference. My system feels totally supported, and stress has been handled. For people that are really sensitive to stimulants, I would recommend this one over Asian Ginseng, as that one really ramps me up. With this product, my body is getting stronger. The ginseng has a building quality. At some point soon, I will work up to 2 a day. One in the morning and one in the early afternoon.
