The best libido supplements have small, early studies behind them. Maca showed modest effects on sexual desire in a systematic review of small trials. Ginseng and fenugreek have limited evidence. Low desire often has causes worth addressing first: stress, fatigue, relationship issues, medication side effects, hormones or depression.
