How to choose
If you are dairy-intolerant, select Orgain Organic Vegan Protein, which is free from dairy, lactose, and soy. Whey options like Optimum Nutrition contain dairy and are unsuitable for this group.
For daily use, Optimum Nutrition offers the best value at approximately $1.20 per serving. Momentous Whey costs approximately $2.50 per serving, making it less sustainable for daily consumption.
If your goal is maximum protein intake, Dymatize ISO100 provides 25g per serving, slightly higher than the 24g in Optimum Nutrition or Momentous.
Choose Orgain Organic Vegan Protein if you require 6g of prebiotic fiber for gut support, a feature absent in standard whey isolates.
Our verdict
Optimum Nutrition Gold Standard 100% Whey is the top pick for most active women due to its $1.20 per serving cost and 24g protein content. Vegans and those with dairy intolerance should select Orgain Organic Vegan Protein for its 21g plant protein and 6g prebiotic fiber.
