Glucosamine is a popular supplement used to treat joint pain and arthritis. It is typically taken in doses of 300-500mg three times a day, for a total daily dose of 900-1,500mg. Most studies have used 1,500mg per day. If you are taking the glucosamine sulfate salt or the “Rotta” formulation, it should only be taken once a day.
It is important to consult with your doctor before taking any supplement, including glucosamine. Your doctor can help you determine the right dosage for your individual needs.
