Rhodiola Supplements: Benefits, Dosage and Safety
Rhodiola supplements are taken for stress-related fatigue and mental tiredness. Some small trials found less fatigue and better concentration, but overall the evidence is weak and inconsistent. It may be mildly stimulating, so it's usually taken in the morning.
