NUTRACOLLAGEN. Our new and improved marine collagen uses finer, higher quality, peptides. As a result, you get a product that is truly tasteless and has no smell. The higher quality peptides also mean that you are getting a product that is easier to mix and pair with other ingredients in your smoothie, oats, etc For most weight loss diets, a healthy amount of protein is required. Just one serving of our marine collagen will yield around 20% of the recommended daily value for the average person. For those on the ketogenic diet, collagen makes the perfect ally: extra protein source, without the carbs.
