Rhodiola has been touted as helping focus during intense exercise. I'm not one of those people. Instead, my bottle of rhodiola lives in my car for my long drives (usu. about 7 hours). After about 5 hours of driving, I'm not as alert and take a tablet. I've found that within a minute or two (not long) after taking it, I feel fresh and alert - not at all jittery or buzzed. The one I use contains rhodiola rosea (root), vit C, green tea extract (leaves), spinach (leaves), and acerola concentrate blend (fruit).
