Glucosamine, as one of the raw materials of nutritional supplements, is widely used in the fields of pharmaceutical, cosmetics and health products. Our company can currently provide two kinds of production process sources, one is extracted from shell, crab shell, and the other is extracted from corn fermentation production technology. Compared with animal-derived products, plant-derived products are safer, cleaner, and can effectively avoid seafood allergies and other reasons. Our two sources have the same effect, which can provide a variety of choices for customers with different needs.
