Longevity Score

88/100

Food Integrity Score

84/100

Solid Choice

One score is excellent and the other is still solid, so this can fit well with a few tradeoffs to keep in mind.

Quick answer

Solid Choice

Optimum Nutrition chocolate whey isolate protein powder drink mix is rated solid choice overall, with a Longevity Score of 88 out of 100 and a Food Integrity Score of 84 out of 100. High-protein, short ingredient list with low sugar and minimal additives; modest processing from isolate and gums. Strengths include high protein per serving (25g), low added sugar (about 1g), and short ingredient list with recognizable items, while main considerations include isolated protein powder is a processed food, thickener (xanthan gum) and flavor additives, and sweetened with stevia extract rather than whole ingredients.
