Every Optimum Nutrition and Dymatize protein product in our catalog is included below, compared on protein concentration (grams of protein per gram of serving).

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:
- A fast-digesting whey for general daily protein.
- Why it stands out:
- Gold Standard Double Rich Chocolate has the highest concentration in this comparison: 0.80 g protein per g of serving, 24g in one 30g scoop.
- Trade-off:
- Concentration varies by flavor. The Extreme Milk Chocolate and Strawberry versions are 0.75 and Cookies & Cream is 0.73, so check the exact flavor you are buying.
Dymatize
Dymatize Elite Casein, Vanilla (4 lb)- Best for:
- Anyone specifically looking for a slow-digesting casein instead of whey.
- Why it stands out:
- Dymatize Elite Casein (Vanilla, 4 lb) has the highest concentration of the Dymatize products here: 0.76, with 25g of protein per 33g serving for 120 calories.
- Trade-off:
- It is casein, not whey, and one serving is two scoops. Every Dymatize product in this comparison is casein, so this is not a like-for-like whey match-up.
