Is Optimum Nutrition halal?
Optimum Nutrition says its Gold Standard 100% Whey is not halal certified, and that the gelatin it uses in its products comes from bovine and porcine sources.
The longer answer
Optimum Nutrition's US support site (checked October 2026) has an article on exactly this question. It says: "Our Optimum Nutrition Gold Standard 100% Whey is not Halal-certified." It adds that the Double Rich Chocolate flavor "is specially formulated to be alcohol free". It does not say the same of other flavors.
A related support article on vegetarian suitability says the powders are generally suitable for lacto-vegetarians because they contain milk-sourced ingredients. On gelatin it says: "All the gelatine we use is derived from bovine and porcine sources." That matters mainly for capsule and softgel products, not for the whey powder, whose ingredients are milk-based.
The statement is about the lack of certification. The company does not say the whey contains a non-halal ingredient.
What to check before you order
The whey powder is not halal certified, so decide whether an uncertified milk-based powder meets your standard. Avoid ON capsules or softgels that list gelatin, since the company says its gelatin is bovine and porcine.
