Glucosamine Dosage

The usual recommended dose of glucosamine for the treatment of arthritis in adults is 1500 mg once daily or 500 mg three times daily. Clinical studies show that it typically takes at least four to eight weeks before any significant benefits are seen. Unlike other dietary supplements (in which not much dosing information is available), glucosamine dosing has been clearly established.

An Introduction to Glucosamine Dosages

Glucosamine is a dietary supplement most often taken for arthritis treatment. Unlike most dietary supplements, glucosamine actually has well-established dosing guidelines.

Glucosamine Dose for Arthritis

For the treatment of arthritis, a glucosamine dosage of 1500 mg once daily (or 500 mg three times daily) taken by mouth is usually recommended. It is not clear if glucosamine products with additional active ingredients, such as chondroitin or MSM, provide any additional benefits. Also, it is not clear if there are any important differences between the different types of glucosamine (glucosamine sulfate, glucosamine hydrochloride, or N-acetyl glucosamine).
Keep in mind that studies have shown that it often takes at least four to eight weeks of use before significant benefit is seen.

General Information on Dosing With Glucosamine

Some considerations for people taking glucosamine include the following:
  • Since the manufacturing of supplements is not closely regulated, it is important to choose a trustworthy manufacturer for glucosamine supplements. Your pharmacist can help you find a supplement from a good manufacturer.
  • If you have any chronic health problems or take any prescription medications, it is a good idea to check with your healthcare provider before taking glucosamine.
  • If you are unsure about anything related to your dosage or glucosamine dosing in general, please talk with your healthcare provider or pharmacist.
