On 100% performance whey protein

Breakdown

7 ingredients to avoid

Optimum Nutrition On 100% performance whey protein scores 15/100 on Tallow — our avoid band. That number comes from what is on the label: the ingredients, how processed it is, and what it is packaged in. It is not a verdict on your diet — Tallow does not weigh calories, portion size or how often you eat it, so a high score means the ingredients are clean, not that the food is unlimited.

Optimum Nutrition On 100% performance whey protein lists 18 ingredients, starting with Whey Protein Isolate, Whey Protein Concentrate, Whey Peptides, Natural Flavors and Lecithin. Ingredients are listed in descending order by weight, so the first few make up most of what you are eating.

At 15/100 Optimum Nutrition On 100% performance whey protein scores worse than most protein powders we have scored. A higher-scoring option in protein powders is Vital Proteins Collagen Peptides Unflavored Powder at 100/100.
