Whey isolate is low in purines and has shown potential xanthine oxidase inhibitory activity, similar to allopurinol but milder 1. Unflavored versions (e.g., Isopure Unflavored) contain no sugar, fructose, or alcohol, making them a clean protein source for gout management 1.

Flavored or sweetened whey isolates may contain added sugars or high-fructose corn syrup, which can raise uric acid 2[3]. Always choose unsweetened unflavored isolates to avoid these hidden gout triggers [3].
