Frequently asked questions

What's the difference between whey isolate and whey concentrate?
Gold Standard uses a blend of both, plus peptides — isolate is more filtered and faster-absorbing, concentrate retains slightly more naturally occurring nutrients. The blend gives you a balance of speed and completeness.

When's the best time to take it?
Most people take it post-workout, but it works just as well as a convenient protein top-up at any point in the day when you're short on protein.

Is this suitable if I'm lactose intolerant?
Gold Standard 100% Whey contains milk-derived protein and isn't lactose-free. If you're lactose intolerant, a whey isolate or plant-based protein may suit you better.
