Collagen is central to your skin health because it makes up about 70% of its dry weight. Supplementing with collagen is important because you decrease collagen production in your skin by about 1% per year after the age of 18.
In a randomized placebo-controlled clinical trial of 69 women ages 35-55, skin elasticity increased by an average of 7% after four weeks of consuming 2.5 grams of collagen. Interestingly, doubling the collagen intake to 5 grams gave the same result. As you might image, skin elasticity was more pronounced in women over 50 years compared to younger women.

I’ve been taking hydrolyzed collagen for about six weeks. I take 7 grams per day and noticed about 3-4 days in that my skin looked healthier. I had less wrinkles around my eyes, most noticeably when I wake up in the morning. I get mine on Amazon from Great Lakes Gelatin Co because it’s from grass-fed cows.
