Two supplements at the same shelf price rarely cost the same to use. Enter price, servings, and dose to compare what you actually pay per day and per gram of active ingredient.
Pure arithmetic on the numbers you enter: price divided by servings gives cost per serving, and dose per serving converts that into cost per gram of active ingredient. Cost per gram is the figure to compare across brands, because serving sizes differ.
Protein powder is convenient, not magic. Comparing a scoop against ordinary food is the fastest way to judge whether a supplement earns its price.
Typical values from USDA food data and standard product labels. Brands vary, and the Daily Value reference for protein is 50 g.
