LONGECITY

Does anyone know about Hyaluronic Acid? It seems like a joint supplement, what life-extension properties does it have?

It helps the cells retain fluid, and as people get older we tend to be more dehydrated.

Here is a link to some more info on HLA:

Cosmos,

I assume you saw the thread on...sci.life-extension about it a while back?

Sorry to revive such a long-dead topic, but I am curious if anyone is taking HA orally. What have you noticed if anything? Any comment on why Sardi is taking it? Thanks in advance, any info/stories would be much appreciated.

I take 100mg of HA per day. My bad knees have improved since I started taking it last Fall, about the same time I started taking resveratrol, Omega-3 fish oil, the Alcar R-lipoic acid combo and numerous other supplements.

Thanks for the input steelheader. Good to know.

The debate about hyaluronic acid, seems to be whether or not it can absorbed by the body if taken orally.

Some people say its molecular weight is too heavy to be absorbed as an oral supplement.

Other people say that the low molecular weight forms of hyaluronic acid, can be absorbed, though it is questionable how helpful at building collagen and cartiledge these lower-weight forms would be.

A third group says even the higher-weight forms would be partially-absorbed through the stomach and intestines.

Bill Sardi seems to be taken a position between the second and third groups mentioned. He feels that hyaluronic acid is much more effective than the glucosamine/chondroitin supplements that many people take for their joint health.

Sounds like placebo effect to me.

I have taken it before. It did seem to help my knees, but not more than glucosamine. I liked it but it cost a lot.

I've taken the Purity Products HA for several years. I have no idea whether it helps, but my joints are all in perfect condition still, AFAIK. I hope to prevent damage in the first place rather than try to repair it.

The marketing by purity and sardi sounds enticing. And HA may do all they say that it does.

However, I have not seen enough studies that would support its use for me so far. Other supplements like resveratrol, fish oil, pomegranate, vitamin D as well as other substances seem to have numerous studies that indicate possible benefit. I look for numerous studies before adding supplements to my regimen.

If someone knows of multiple references to HA studies, I would be interested in seeing them.

what is so good about vitamin D?

Here are some vitamin d references. I just did a quick google cut and paste. Too much vitamin d(as with many things) can be detrimental and even life threatening.
