I've been buying from iherb for over a decade and have roughly calculated that I've spent many thousands of dollars on supplements to help with fatigue.
Its not in question whether this particular supplement is legitimate, good quality, pure and of a good brand. I am open to all that being true. Though, I can only tell you my experience. That is, I didn't notice any difference in my health and well-being as a result of taking this supplement either for a few days or for many weeks.
Actually, one of the very few noticeably effective supplements I've ever bought from iHerb and will continue to buy is Thorne Advanced Nutrients multivitamin. I surprisingly do feel better, more alert, more charged and energised within an hour of taking 2-3 capsules, which is less than half the recommended dose. This is a very rare result for me.
