Pure whey isolate is a low-purine, gout-friendly protein that may help lower uric acid [1].
Good
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].
Bad
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].
