Is it safe to take a higher dosage of glucosamine?

Question:
According to your scientific insights, what is the maximum allowed dosage of glucosamine a day? Can a woman around their fifties take circa 3000 mg on a daily basis? My mother is using two tablets of 750 mg a day and wants to raise the amount to 4 tablets. I wanted to check the safety of this high dosage with you.

Answer:
We advise against this. A higher dosage of 3000 mg will probably not have any more effect. Moreover, the chance of side effects will become greater. Such a high dosage can have a negative impact on the insulin sensitivity and may lead to problems involving the blood sugar level on the long term.

If glucosamine does not have the wished effect at the recommended amount, it is more safe and effective to start combining glucosamine with chondroitin (1200 mg a day).

Another even better supplement that can replace glucosamine and chondroitin is Arthro-5. It does not only contain glucosamine and chondroitin, but also MSM, ASU and Hyal-Joint.
