I noticed an immediate increase in energy taking this product, despite the calming attributes of ashwaganda. I must be sensitive to the ginsengs in this product. There is both Siberian & Asian Ginseng, albeit, very small amounts. I take first thing in morning & it hasn't disrupted my sleep, so that's good. I was looking more for a calming effect from this product(given ashwaganda content). Not everyone responds to ginseng as I do(from what I've read, it can provide relaxation). I'll definitely finish the bottle as I do like the energy boost.
