Common questions

Is Optimum Nutrition Whey protein isolate healthy?

Optimum Nutrition Whey protein isolate scores 100/100 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.

What is in Optimum Nutrition Whey protein isolate?

Optimum Nutrition Whey protein isolate lists 1 ingredient, starting with Sunflower Lecithin. Ingredients are listed in descending order by weight, so the first few make up most of what you are eating.

Does Optimum Nutrition Whey protein isolate contain seed oils?

No. Nothing in Optimum Nutrition Whey protein isolate’s ingredient list matches a seed oil — canola, soybean, corn, cottonseed, grapeseed, sunflower, safflower, rice bran or peanut oil, or an unspecified "vegetable oil".

How processed is Optimum Nutrition Whey protein isolate?
