FlexAble Glucosamine Sulfate is a sodium-free formula for joint and cartilage support. It stimulates the formation of key components of cartilage, reduces joint pain, and protects against the deterioration of cartilage from chronic joint diseases. This is an ideal product for people with osteoarthritis who are on low-sodium diets.
Glucosamine sulfate is a natural joint support found in the fluid around joints. When digested, it stimulates the production of key building blocks that form the cartilage needed for repairing joints. It also protects the existing cartilage and connective tissue of joints and increases cushioning to improve mobility and function. This makes glucosamine sulfate very useful for relieving the painful symptoms of degenerative joint conditions, such as osteoarthritis, and can help slow the progression of joint degeneration. Natural Factors FlexAble Glucosamine Sulfate is made with potassium instead of sodium, making it an ideal glucosamine sulfate formula for people who wish to reduce their sodium intake or those with hypertension. Each easy-to-swallow capsule delivers 500 mg of glucosamine sulfate and is taken multiple times per day to achieve an optimal daily intake of 1500 mg. Supplementing the diet with glucosamine sulfate is an effective and natural way to optimize joint health and reduce the need for non-steroidal anti-inflammatory drugs (NSAIDs). It is an extremely well-tolerated, time-tested nutrient. Healthy joints are a key factor in physical mobility, comfort, and maintaining a quality active lifestyle.
