Nutrition & ingredients
According to the label, each 30 g scoop provides 24 g of protein, 1 g of fat and 3 g of carbohydrates, of which 1 g is sugar. The formula combines whey protein isolate, concentrate and hydrolysed whey peptides, offering a range of digestion speeds.
Other ingredients include lecithin for mixability and small amounts of sucralose and acesulfame K for sweetness. The product is gluten‑free but contains lactose. Those with severe lactose intolerance may prefer an isolate or a plant‑based alternative.
The profile includes 5.5 g of BCAAs (2.5 g leucine), plus glutamine and glutamic acid. These amino acids are commonly noted in the nutrition community for their role in supporting protein intake.
Taste & mixability
Taste is subjective, but customer feedback consistently rates Gold Standard Whey highly for flavour and mixability. Popular flavours include Double Rich Chocolate, Vanilla Ice Cream and Strawberry Banana. According to reviews, it mixes smoothly in water or milk alternatives with minimal clumping or foam, and many users find it versatile for adding to smoothies, oats or baking.
Use cases
Gold Standard Whey is marketed as suitable for post‑exercise recovery or daily protein supplementation. Customer experiences suggest it works well as a convenient shake after workouts, between meals or in recipes.
Because it contains whey concentrate, it is not completely lactose‑free. Individuals with mild intolerance may tolerate it, but those with severe lactose intolerance often choose whey isolate or plant‑based proteins.
