Is Gold Standard Whey a complete protein?

Yes. Whey is a naturally complete protein containing all nine essential amino acids and it scores high on both PDCAAS and DIAAS. For more detail on what these scores mean, see our guide on PDCAAS vs DIAAS.

When should I take Gold Standard Whey?

Most people take it within 30 to 60 minutes after a workout to support recovery and muscle protein synthesis. It also works as a between-meal shake on busy days, or blended into oats or smoothies in the morning.

Is Gold Standard Whey gluten-free?

The product itself is gluten-free, but the label states it is produced in a facility that also handles wheat, soy, and egg. It is not certified gluten-free for those with celiac disease, so always check the latest label before buying.

Does Gold Standard Whey cause bloating?

Because it contains whey concentrate plus small amounts of lactose, people with lactose intolerance may experience mild bloating. If that happens, switch to a whey isolate or a plant-based option like OWYN Pro Elite, which is lactose-free.
