That is my only question about this. I heard that the product of this, hyaluronic acid, aids in liquid retention, might be a key in the longevity and health produced by diets based on starches such as potatoes, some report it improves eyesight, skin tone, among other benefits. I think I might have low production because I get a lot of dandruff, the hyaluronic acid inside my eyes is likely breaking down too, hence either I am not producing enough (unlikely), or something is braking it down too fast, might be related to the liver and oxidation (more likely), or to the immune system (just as likely).
