Hyaluronic acid (HA) is also known as hyaluronan or hyaluronate. It's a gel-like molecule that holds water and acts as a space filler and cushioning agent in all mammals. Roughly 50% of the Hyaluronic Acid in the body is in the skin. Aging causes levels of hyaluronic acid to fall - perhaps by as much as 50%. Genetics, smoking and deficiencies of magnesium and zinc seem to speed up this loss - though we all experience it to some degree. The result of which is aching joints and sagging skin. Our Hyaluronic acid is the highest quality with molecular weight 1.0-1.5 Million Daltons. Molecular weight of Hyaluronic acid directly influences its bioavailability and absorption, hence our 140mg capsules are in fact stronger than 600mg 500-700 kDa offered by other manufacturers. Suitable for vegetarians and vegans. Manufactured & packed in the UK to GMP standards. Letterbox friendly packaging. Established in 2005, Health4All is a family-owned nutritional supplements brand based in Lancashire. We make our vitamins and supplements to exacting standards.
