1.Does the Hyaluronic acid products safe?
Current available information indicates that our hyaluronic acid products are as safe as taking vitamin C. Using the recommended daily doses provided on our labels should create no problems. We have found that even people who tried taking other glucosamine and chondroitin products and reported intestinal problems tolerate our products very well without any side-effects. Since hyaluronic acid occurs in the body naturally, there is little concern for the supplementation in the small effective amounts in our products 2.How much HA should I take?Our bodies are in a continual state of rebuilding. New skin cells for example replace old ones about every 20 to 30 days. Normally, HA in skin tissue is broken down by an enzyme called Hyaluronidase at a precise rate. The rate of HA degradation can be increased by excess intake of riboflavin (B-2), ultraviolet radiation exposure and viruses. Any long-term overexposure to any of these may result in premature connective tissue destruction.<BR>Considering that 10-150 mgs of HA is a normally metabolized or excreted daily with the higher rate of loss in persons over 50, it may make sense for older adults to begin supplementing with 1- 50mg capsule 3 times daily just to maintain equilibrium

3.Hyaluronic Acid And The Aging Process
Unfortunately, as our age increases, our hylaronic acid production decreases. That is why elderly people complain of being stiff or having joint pain. This stiffness is often associated with arthritis. When hyaluronic acid production slows, it not only affects the joints, it affects every part of the body. Their skin becomes dry; hence, wrinkles. Doctors have been using hyaluronic acid to treat patients with arthritis, eye problems, even cosmetic surgery! There are now many hyaluronic acid products available through your doctor office or online. Hyaluronic acid supplements not only benefit arthritis patients. Others who use these products report having healthier and softer skin, clearer vision, and increased energy

4.HA and Improving Sleep
Sleep is the primary repair time of the body. It has been our experience working with this supplement that sleep is significantly enhanced in terms of restful and restorative quality. Since it is known that HA declines with age, it stands to reason that a lack of HA may be a prime reason why individuals do not sleep deeply or as long as they get older. This means that HA has a place as a general anti wear and tear nutrient of great importance, especially when taken before bed. It is worth a try by anyone who does not sleep well or feel well rested.

5.HA in the skin
Hyaluronic acid plays a vital role in the skin. The dermis of the skin comprises a network of collagen fibers within an interstitial substance composed largely of hyaluronic acid. The elastic properties of hyaluronic acid offer resistance to compression, so that the skin protects underlying structures against damage. At the same time, the non-Newtonian properties of hyaluronic acid allow the collagen fibers to move easily through the interstitial substance. This lubrication by hyaluronic acid allows the skin to accommodate the changes in shape and volume that occur when the underlying bones and joints move.The hyaluronic acid gel in the skin also inhibits movement of foreign particles, such as bacteria. This makes an important contribution to the skin defensive function as a barrier to infection. The barrier also affects the free passage of other exogenous material, such as some drugs. This is the reason why some subcutaneous injections and drugs in creams or ointments include a small amount of the enzyme hyaluronidase. The enzyme degrades the hyaluronic acid gel around it, so that the drug is able to pass more freely through the tissues of the skin.
When we get older, the amount of HA in the skin diminishes as the skin cells lose their ability to produce hyaluronic acid. In addition, the molecular weight of the HA is decreased with age, so that it does not hold water as well as before. This can be demonstrated by squeezing the skin between the fingers. In young people, the skin rapidly restores itself to its original volume. However, as we get older, the skin抯 ability to restore itself is reduced.

6.Content and storage of HA
The content of HA in cosmetic is 0.1-0.3% commonly. Some products having special usage shall have 0.5% HA in them. HA shall be stored at 0-10oC
