Ascent Native Fuel Whey sets itself apart with a process most consumers do not know about: native whey. While most whey protein is a byproduct of cheese manufacturing, Ascent produces their whey directly from fresh milk using a proprietary cold filtration process. This preserves the protein in its most natural state with higher leucine content and better bioavailability.
Optimum Nutrition Gold Standard 100% Whey is the best-selling whey protein powder in the world, and for good reason. With 24g of protein per scoop from a tri-blend of whey isolate, concentrate, and peptides, it delivers a well-rounded amino acid profile including 5.5g of BCAAs and 11g of EAAs per serving. The Double Rich Chocolate flavor is consistently praised as one of the best-tasting protein powders on the market.
Ascent Native Fuel Whey Protein edges ahead with an overall score of 78 vs 76. For value, Optimum Nutrition Gold Standard 100% Whey wins with a 78/100 value score.
