The unique ingredients in ProFlex avoids this by nutritionally supporting the systems involved in the long term health of the horse.About the Ingredients Glucosamine is found in tendons, ligaments, synovial fluid, muscle membranes and several structures in the eye, blood vessels and heart valves. Methylsulphonylmethane (MSM) is a source of sulphur that is converted into an important component of connective tissue. It may have a role in supporting normal osteo and oxidative function. Lysine is an amino acid that when fed along side vitamin C, is extremely important in the structure of cartilage tissue and protein synthesis. Gelatin and Spirulina: Collagen is a fibrous protein that connects to muscles, bones and skin - making them stronger. Gelatin is pure collagen that has been processed into a powder. Spirulina is 65% amino acids and is one of the world’s most nutrient rich ingredients. Spirulina and gelatin form a powerful relationship to support the horse’s natural process of producing collagen for healthy muscles, bones and skin. Vitamin C is an essential element for the formulation of the hydroxyl groups needed in cartilage synthesis. Vitamin C deficiency may result in reduced production of collagen - the protein based structure in tendons and ligaments. Zinc is required by over 70 different enzymes to function. In this instance zinc is used in the hydrolysis and cross linking needed for collagen formation. The citrus bioflavenoid hesperidin in ProFlex may support antioxidant function. Gotu kola is a herb that may support the production of chondroitin sulphate and hyaluronic acid.
