One of the biggest differences is in the amino acids: Collagen is high in glycine – an anti-inflammatory amino acid that heals your body. Yet unlike even the highest-quality whey, it’s also low in cysteine – the part that normally sabotages your performance if you get too much of it.
That means you can safely consume another four tablespoons (25 grams) or more worth of supplemental protein from collagen each day without the typical inflammation and digestive problems. While getting this extra dose of protein from collagen can help you build or maintain muscle if you’re working out – you don’t have to pump iron to benefit.
In fact, most people who try collagen enjoy it the most for its other benefits like faster recovery after exercise, boosting energy and mental clarity, and even upgrading your skin with a radiant, healthy ‘glow’.
