Why does one complex contain three components at once — glucosamine, chondroitin and MSM? — Glucosamine + MSM + Chondroitin, 90 Tablets OstroVit

The complex combines three substances, and according to the manufacturer's description together they support joint health and general well-being. Here is what the product page says about each of them:

• Glucosamine sulfate — an organic compound that the body produces in small amounts; its ability to synthesise it decreases with age. OstroVit uses the sulfate form, which the manufacturer considers the most bioavailable.
• Chondroitin sulfate — a substance from the group of mucopolysaccharides. The body produces it naturally, but its level and capacity for synthesis decrease with age.
• MSM (methylsulfonylmethane) — an organic sulfur compound; according to the description, it takes part in the synthesis of collagen and keratin, which are important for the health of hair, skin and nails.

Content per portion (2 tablets): glucosamine sulfate 1000 mg (including glucosamine 590 mg), MSM 600 mg, chondroitin sulfate 400 mg (including chondroitin 360 mg). Taking the three substances in one product is more convenient than buying them separately. This is a food supplement, not a medicine.
