Vital Proteins believes that whole-food-based nutrition containing collagen is beneficial for looking and feeling your best. Compared to our ancestors, our diets today contain less collagen, and this natural protein has been removed by modern food processing. We are committed to providing products that help add collagen to your diet. Vital Proteins Collagen Peptides - Unflavored are sourced from grass-fed, pasture-raised bovine hides to ensure a high-quality source of this ancient nutrient. Collagen is the most abundant protein in the body supporting the health and vitality of your skin, hair, nails, bones and joints. Collagen helps to maintain healthy joints and supports bone strength. It also enhances skin hydration, can improve skin elasticity, and helps to maintain firm skin. Vital Proteins peptides are easily digestible and soluble in cold or hot liquids.
