I've recently started taking herbs. The last ones I've added are Rhodiola Rosea Root, 400 mg. and Kava, 200 mg.. Kava can be very potent. The kava capsules I purchased was 200 mg. That was too much. I remove half of the Kava and take it at bedtime. The Rhodiola I take in the afternoon. Usually after lunch.
2 times a day I take 100mg. of niacin with 400mg. of Turmeric.
I suggest you look into these supplements. The internet is flooded with information regarding them.
I do notice days when I miss them. I hustle to go take them.
