There are many HA products available now on the market making your shopping choice all the more important. Indeed we expect to see more innovative HA formulas well in the near future. The most absorbable and reliable choice would be a high molecular weight HA, around the 2.4-3 million Daltons range, according to experts writing in 2004 in the Journal of Applied Nutrition who examined the different kinds available. The researchers note, “dietary supplements containing HA are not equivalent due to the inherent properties of the three major types of HA commercially available as dietary supplement materials. Consumers and health care professionals need to be aware of the different types of HA and their very large differences in properties (even before ingestion). One source, hydrolyzed chicken sternal cartilage, is clearly unlike native HA, does not match the biological properties of native HA, and consequently should not be represented as HA to consumers on product labels…” Ultimately, the researchers recommend bio-identical high-molecular weight HA, purified non-animal HA because it most closely resembles the substance found in the body. It is this HA that has powerful anti-aging and lubricating qualities. Now, go out and get young again with HA!
