Both MET-Rx Natural Whey and Optimum Nutrition Gold Standard 100% Whey are designed to support muscle growth and recovery, making them ideal for fitness enthusiasts and athletes. MET-Rx Natural Whey offers 23g of protein per serving, with a slightly higher carb content due to the use of Whey Protein Concentrate as the primary protein source. On the other hand, Optimum Nutrition Gold Standard provides 24g of protein per serving, with a blend of Whey Isolate, Whey Concentrate, and Hydrolyzed Whey Peptides. This blend offers a more balanced protein supplement, with each form providing unique benefits.
After careful consideration, we believe that Optimum Nutrition Gold Standard 100% Whey is the superior product. It offers a higher protein content and a more balanced blend of protein sources, which can provide a broader range of benefits. Additionally, it includes digestive enzymes to aid in the digestion of the small lactose content, which is a thoughtful addition for those with lactose intolerance. The product also offers excellent mixability and a wide range of flavors, making it a versatile and convenient choice for many. While MET-Rx Natural Whey is a solid option, especially for beginners, Optimum Nutrition Gold Standard's comprehensive formulation and proven performance make it our top pick.
