N-Acetylglucosamine (NAG) (GreeNAG)
N-Acetylglucosamine (NAG) is a naturally occurring amino sugar that plays a vital role in joint health, skin hydration, gut lining integrity, and immune function. As a building block of hyaluronic acid and glycosaminoglycans (GAGs), NAG contributes to cartilage repair, skin elasticity, and gastrointestinal protection, making it beneficial for conditions like osteoarthritis, inflammatory bowel disease (IBD), and skin aging.
What is N-Acetylglucosamine (NAG)?
NAG is a derivative of glucosamine, an essential component of connective tissues, cartilage, and the extracellular matrix. Unlike standard glucosamine, NAG has enhanced bioavailability and absorption, making it more effective for joint lubrication, gut barrier support, and skin hydration.
Health Benefits of NAG
- Supports Joint Health and Cartilage Repair
NAG helps maintain joint flexibility and cartilage structure by promoting the synthesis of hyaluronic acid and glycosaminoglycans (GAGs). This can be particularly beneficial for individuals with osteoarthritis, joint pain, and stiffness. - Enhances Skin Hydration and Anti-Aging
As a precursor to hyaluronic acid, NAG helps retain moisture, improve skin elasticity, and reduce fine lines. It also supports collagen production, making it a valuable ingredient in anti-aging skincare. - Promotes Gut Health and Intestinal Barrier Function
NAG plays a crucial role in maintaining the integrity of the gut lining. It has been studied for its potential in managing inflammatory bowel diseases (IBD) like Crohn’s disease and ulcerative colitis, as it helps repair damaged intestinal mucosa and reduce inflammation. - Regulates Immune Function and Inflammation
NAG has immunomodulatory effects, helping to regulate excessive immune responses and inflammation. It has been investigated for its role in autoimmune disorders and chronic inflammatory conditions. - May Support Blood Sugar Metabolism
Some research suggests that NAG may help regulate glucose metabolism and improve insulin sensitivity, though more studies are needed to confirm its effects on diabetes and metabolic health.
