We have been running for almost 20 years now; marathons and countless shorter distance road races. We regularly run every week, anywhere from 2 to 5 days per week. That adds up to tens of thousands of miles, or kilometres for the younger crowd. We have no joint issues. Zilch. Zero. Nada. None. We credit diet for that. A diet that includes some of the best collagen protein that we can buy.
Collagen is also helpful for improving skin tone, growing hair, boosting metabolism, reducing scars and stretch marks, and strengthening teeth and nails. It's similar to bone broth, without the fuss and the mess. Because it's hydrolyzed using natural enzymes, it's pre-digested. This results in a 95% absorption rate.
