There is a product I’ve just heard about called Nutriglow that is a drink mix that contains collagen in it which apparently will help prevent wrinkles when injested regularly. Can collagen being injested rather than injected or applied topically also effect the appearance or all out prevent wrinkles?
We found a few studies that look promising. The first one was just a pilot study and it was an open label test which means that it was not blinded or placebo controlled. The researchers had 26 females take a 1 gram of a supplement containing hydrolyzed Type II collagen, hyaluronic acid and chondroitin sulfate daily for 6 weeks. They then measured improvement in several factors including the degree of skin dryness and scaling and the degree of lines and wrinkles. Results showed a statistically significant improvement in each of these. Of course this study is not very conclusive because of its small size, the study design (it was not blinded), and the fact that they mixed collagen with other ingredients so you can’t tell what’s really supplying the benefit. http://www.ncbi.nlm.nih.gov/pubmed/22956862. The second study was a little more robust….This was a larger study (about 200 people) and it evaluated the effect of daily consumption of a specific type of collagen supplement on facial wrinkles. But it was open label too. Not double blinded. or placebo controlled however. http://www.dovepress.com/daily-consumption-of-the-collagen-supplement-pure-gold-collagenreg-red-peer-reviewed-article-CIAA third study we found on hydrolyzed collagen was double-blinded and placebo-controlled. It consisted of 69 women who were randomized to receive 2.5 g or 5.0 g of CH or placebo once daily for 8 weeks. The researchers measured changes to skin elasticity, skin moisture, transepidermal water loss and skin roughness. Their results showed a statistically significant increase in skin elasticity at both collagen dosages for the older women in the study. There were directional improvements but no other statistically significant results. http://www.ncbi.nlm.nih.gov/pubmed/23949208What does all this mean? I wouldn’t say these studies are conclusive but there are data here to indicate that ingested collagen MAY benefit your skin.Tangentially, can you guys point us to a database that lets us know if the vitamins/supplements etc. really contain what they are marketed as containing? I’ll try the collagen – supposed to be good for joints too – but I’d like to be certain I get what I pay for.
Go to consumerlab.com – they are the Consumer Reports of nutritional supplements. They measure what is in the actual supplement on the market and then rate it against others.
They’re the “Supplement Brains” tough not as entertaining as the “Beauty Brains”. : )Ciao,L
