Random, interesting studies

Topical Oxidized Vitamin C (DHA) permeates through skin 12x faster than ascorbic acid.

Even though the human study below is from a company that produced the product with DHA, it seems to be very carefully done with practical considerations.

Topical Dehydroascorbic Acid (Oxidized Vitamin C) Permeates Stratum Corneum More Rapidly Than Ascorbic Acid

@Lejeboca yes I saw that one too but hadn't clicked on it. Thanks for sharing.

Sorbitol

I'd be careful with sorbitol. The issue with sorbitol is that it is often made with a nickel catalyst, which leaches into the endproduct.

" The Cr/Fe promoted system exhibits the highest activity but the Fe leaches from the catalyst into the reaction mixture. Moreover, this catalyst deactivates after successive runs. For all Raney-type Ni catalysts leaching of Ni in the product mixture occurs."

Although Ray said a little is ok:

Me: Is sorbitol o.k. to eat? I got some gummy bears that have it in them.

Peat: A little is o.k.

Papaya/Papain

Papain reverses the effects of a high fat diet in mice. The mice getting Papain, did not gain more weight than the mice on a normal control diet.
Papain even lowered visceral fat content slightly below the control group.
It lowered liver enzymes, triglycerides, adipogenic and inflammatory Markers.
It also drastically upregulated AMPK, similarly to aspirin, biotin or infrared light.

@Mauritio Seems to be an affordable experiment to try: a kg costs only 90 dollars

@alfredoolivas why would you want a KG of it to experiment with it ??

alfredoolivas

@Mauritio I don't want to experiment with it, I was just pointing it out because

1.) Animal studies often use large doses, that aren't feasable with dosages found in OTC supplements
2.) Raw materials are rarely food / USP grade, and this was food grade. They also can be expensive and not sold to private individuals.

So I was letting you know about it, incase you wanted to try it.
