How We Compare Protein Powders

Instantly compare protein powders by price per gram of protein, serving size, and total cost. Find the cheapest, most cost-effective protein powder for your needs—whether you're looking for whey, plant-based, or vegan options. Our data is updated regularly and sourced directly from Amazon for accuracy.

We calculate price per gram of protein for every product using the formula:

Price per gram = Total Price ÷ (Number of Servings × Protein per Serving)

This lets you see which protein powder gives you the most protein for your money, regardless of container size or marketing claims. We only use real, up-to-date prices and product info from Amazon to ensure fair comparisons.
