If you are here, you already know the benefits of collagen to the body. So I'll just say it goes GREAT in my coffee every morning after a workout. Fast shipment, rewards system, and loyalty discounts. Nuff said!
The best Collagen by far!
We love these products. They are the best available hands down. We feel good about having our teenager take these products!
Love it. Put it in coffee, no taste all the benefits
