Glucosamine (Glucosamine Sulfate)

Glucosamine is a substance found naturally in the synovial fluid that lubricates joints and in cartilage tissues that connect joints, acting as a natural shock absorber that helps protect your body from everyday stresses of movement and exercise like walking, jogging and climbing stairs. It’s the second most popular supplement in the United States (after fish oil), and numerous studies have explored glucosamine sulfate’s potential benefits for joints. Glucosamine may be particularly helpful for flexibility of knee joints in men. Glucosamine sulfate supplements are derived from shellfish, so if you have a shellfish allergy choose a vegan glucosamine supplement instead.
