Visi is offering free provita protein chews for those interested in trying out their protein products. Provita is a collagen based protein product that comes in a chew-able form. Collagen based protein products are great because they occur naturally in the body. This is not an animal based protein like whey. This is suppose to give the product a better delivery than a typical protein. A bag of these products run as high as $75 so this is one heck of a freebie to try. Protein products tend to be very bad tasting and I hope this one has a good taste to it.
