Product Overview


  • Science-Based Nutrition
  • Helps Maintain Healthy Joints
  • Dietary Supplement
  • Non-GMO / Gluten Free / Soy Free

Doctor's Best Synergistic Glucosamine / MSM Formula supplies several building blocks for healthy joints. Glucosamine sulfate supports joint structure and functions and supplies healthy joints with proteoglycans, which contribute to healthy joints and connective tissues. Methlylsulfonylmethane (MSM, from OptiMSM) supplies bioavailable sulfur needed for joints. OptiMSM is purified via distillation for highest purity and consistency and is an excellent source of sulfur. Vitamin C is essential for the production of collagen, a structural protein.

  • Glucosamine Sulfate helps support normal, healthy joint function and helps maintain healthy joints.
  • MSM helps support organ and joint function by donating sulfur for maintenance of healthy connective tissue.
  • Vitamin C helps in the production of collagen.

Odlican proizvod

Posted by iHerb Customer on February 8 2018 | Verified Purchase

Moji roditelji imaju preko 80 godina, tesko se krecu i imaju bolove u zglobovima. Ovaj proizvod im je mnogo pomogao, odusevljeni su njime i kazu da bolove vise ne osecaju i krecu se mnogo bolje. Skoro da su elasticni kao pre :)

Thanks for your feedback!

Disappointed, different expired date and dented bottle

Posted by iHerb Customer on October 30 2017 | Verified Purchase

Bought 4 bottles, one bottle received with expiration date 06/2018 instead of 06/2019 and with big dents, looks this spoiled one.

Thanks for your feedback!
