ISOPURE

Breakdown

1 ingredient to avoid

ISOPURE scores 79/100 on Tallow — our clean 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.

ISOPURE lists 7 ingredients, starting with Whey Protein Isolate, Vitamin and Mineral Blend, Dicalcium Phosphate, Potassium Chloride and Magnesium Oxide. Ingredients are listed in descending order by weight, so the first few make up most of what you are eating.

At 79/100 ISOPURE sits in our top band, among the better protein powders we have scored. A higher-scoring option in protein powders is Truvani Plant Based Protein, Unflavored & Unsweetened, 19.75 oz at 100/100.
