NAG Supplement - N-Acetyl Glucosamine for Joint Health

N-Acetyl Glucosamine is a muco-polysaccharide precursor of hyaluronic acid, an essential component of the synovial liquid which lubricates the joints.

What are the benefits of N-Acetyl Glucosamine?

Many studies have shown that NAG helps the organism repair damaged cartilage, reduce inflammation and pain, and help restore mobility in the joints. NAG is much better absorbed by the organism than simple glucosamine sulphate. NAG is used preferably together with Chrondroitin Sulphate.

Why should N-Acetyl Glucosamine be used with Chondroitin Sulphate?

"In itself, each of these two products are effective, but together they can fulfil the expectations of millions of suffering patients: Chondroitin and Glucosamine are effective where other products and surgery fail." To be qualified as chondroprotective (i.e., which protects the cartilage), a substance must:

  1. Favour macro-molecular synthesis of cartilage cells (glycosaminoglucans, proteoglycans, collagen, proteins, ARN and DNA).
  2. Favour hyaluronic acid synthesis (the substance which gives the synovial liquid its viscosity and enables lubrication between the synovial membrane and cartilage).
  3. Inhibit the enzymes responsible for macro-molecular damage of the cartilage cells.
  4. Reinforce the mobility of clots, fibrins, lipids and cholesterol deposits in the articular inter-spaces and the blood vessels of the joints.
  5. Relieve articular pain.
  6. Reduce synovial inflammation.

Clinical studies have shown that Glucosamine enables to attain objectives 1), 2), 5) and 6), whereas Chondroitin Sulphate enables to attain objectives 1), 3), 4), 5) and 6). Alone, no product or nutritional supplement can do all. It is, therefore, because their effects overlap, that their association is so effective against arthrosis.
