Dymatize ISO100 is one of the highest-quality whey protein isolates on the market. What sets it apart is the hydrolysis process, which pre-breaks down the protein into smaller peptides for faster absorption. Each serving delivers 25g of protein with only 110 calories, 0.5g of fat, and 2g of carbs, making it one of the leanest protein options available.
Levels Grass-Fed Whey is the product that proves you do not have to choose between clean ingredients and good value. At $0.79 per serving from the 5 lb tub, it is one of the most affordable grass-fed proteins available — cheaper than many conventional whey options. The 76-serving container means it lasts over two months of daily use.
Levels Grass-Fed Whey Protein takes the lead with an overall score of 80 vs 79. For value, Levels Grass-Fed Whey Protein wins with a 82/100 value score.
