New Chapter has very natural sourcing. I have switched from another brand to this one. Rhodiola seems to work for me as an adaptogen and I feel relaxed after taking it and it seems to boost my strength and performance at the gym.
My 20 year-old daughter has been taking this for about 6-9 months, and I've definitely seen a difference in her overall well-being. She used to have mild depression and moodiness many days out of each month - now I seldom see her down. I credit Rhodiola Force.
