Highest-Protein Whey Powders, Ranked
This list is limited to products with "whey" in their own product name — we're not classifying formulas ourselves, just filtering to what the label already claims. They're ranked by protein concentration (grams of protein per gram of serving), the number that shows how much of each scoop is actually protein versus filler.

Quick picks
Our read of the label data below. Each pick comes with its trade-off.
Optimum Nutrition
Gold Standard 100% Whey - Double Rich Chocolate (2 lb)- Best for:
- First-time buyers who want a standard 2 lb tub of a widely sold whey.
- Why it stands out:
- Ties for the top protein concentration in this ranking: 24g of protein in a 30g scoop (0.80 g per g of serving) for 120 calories.
- Trade-off:
- It is a traditional whey, not a clear isolate, so it carries 5.0 calories per gram of protein versus 4.0 for the Myprotein clear isolate below.
Myprotein
Myprotein Clear Whey Isolate, Peach Mango (1.1 lb, 20 Servings)- Best for:
- Shoppers who want the fewest calories per gram of protein.
- Why it stands out:
- Also 0.80 g protein per g of serving, with 20g of protein for 80 calories (4.0 calories per gram of protein).
- Trade-off:
- The 25g scoop delivers 20g of protein, 4g less than a Gold Standard scoop, and clear isolates are built to drink like juice rather than a thick shake.
Optimum Nutrition
Gold Standard 100% Whey - Double Rich Chocolate (5 lb)- Best for:
- Regular users who would rather buy a bigger tub than reorder often.
- Why it stands out:
- The same label as the 2 lb tub (24g protein, 120 calories per scoop) in a 74-serving 5 lb size.
- Trade-off:
- A bigger commitment to one flavor. Try the 2 lb size first if you have not used this product before.
