Promix Grass-Fed Whey Isolate and Levels 100% Grass-Fed Whey Protein are both designed to offer a high-quality, grass-fed whey protein source for fitness enthusiasts. They share the common purpose of providing a clean, minimally processed protein that supports muscle recovery and growth. Promix stands out for its use of whey protein isolate, which is a more refined form of protein with less fat and lactose. Levels, on the other hand, uses whey protein concentrate, which retains more of the nutrients found in the whole milk.
Despite the similarities, we lean towards Levels 100% Grass-Fed Whey Protein as the superior product. While both products offer a good amount of protein, Levels' product provides a slightly richer protein content for a concentrate. It also offers excellent mixability and a pleasant taste, which can enhance the overall experience of consuming the protein powder. Although Promix's product uses whey protein isolate, which is typically seen as a higher-quality protein, the lack of digestive enzymes may be a drawback for some users. Levels' product, while using a less refined form of protein, offers a higher protein content, making it our preferred choice.
