This smaller molecular size allows for faster and more efficient absorption, which is important for maximizing collagen's skin, joint, and hair benefits (it's actually closer to marine collagen of 4,000 Dalton size!).  Our bovine collagen is also free of:- Growth Hormones- Antibiotics,- BSE & TSE- Ethylene Oxide- Additives- Irradiation- Nitrosamines- Melamine Around the age of 25, your body starts to lose its ability to produce collagen, this super-protein that makes up over 75% of your skin, hair, nails, bones, and muscles.

However, drinking our collagen formula has been clinically proven to reverse those effects on skin & hair by rebuilding stronger cells!
