Most instructions for the use of Maca suggests to take 2-3 capsules daily. Since Maca is considered a food and not really a supplement, its been reported its safe to take. Personally from my experience with Maca Root, start with two pills for 2 weeks. Research includes to not take Maca for long periods of time. Some suggest consuming Maca for four weeks then take break for one week. Other reports say to take it for 90 days then stop for 30 days and once you get to your desired weight goals, you can stop use completely.
