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.
NOW Sports Whey Protein Isolate combines two things that rarely go together: Informed Sport certification and budget-friendly pricing. At $64.99 for 78 servings, it delivers 25g of protein per scoop at just $0.033 per gram of protein — an exceptional value for a sport-certified product. NOW Foods has been a trusted supplement manufacturer since 1968, bringing over five decades of quality assurance to every batch.
NOW Sports Whey Protein Isolate takes the lead with an overall score of 88 vs 80. For value, NOW Sports Whey Protein Isolate wins with a 85/100 value score.
