ask your pharmacist

How do I choose a glucosamine product?

Select a glucosamine product from a reputable company such as >Nature Made, GNC, or Alfexa. This way, you can be more certain that the amount of the active ingredient listed on the product's label is actually in the product.

Also consider using a chondroitin and glucosamine combination. Studies have shown that both glucosamine and chondroitin may be effective in reducing some people’s arthritis pain. Using a combination product may be more convenient, allowing you to take fewer pills each day. Several reliable combination products include Sundown, GNC and >Cosamin DS.

Glucosamine doesn't work for everyone. If you don't notice an improvement in your symptoms after 8 weeks, it is unlikely that glucosamine will work for you. It also isn't intended to replace prescription medications or your doctor’s medical directions. If you do chose to take glucosamine, please let your doctor and pharmacist know.
