Optimum Nutrition Gold Standard 100% Whey: 24g protein per scoop
Optimum Nutrition Gold Standard 100% Whey is the brand's flagship protein powder and one of the most-recognised whey formulas in sports nutrition. Each 30g serving delivers 24g of protein at 120 calories, with 1.4g of fat, 3g of carbohydrates and 1g of sugars. The 1.67kg tub provides approximately 56 servings.
The protein blend leads with whey protein isolate as the primary source, supported by whey protein concentrate and whey peptides for a multi-fraction amino acid spread. Each serving delivers approximately 5g of naturally occurring BCAAs and 4g of glutamine and glutamic acid, with leucine at the front of the BCAA ratio for muscle protein synthesis signalling. The hydrolysed peptide component supports faster amino acid delivery post-training versus concentrate alone.
What separates Gold Standard from a value-tier whey is the brand legacy and the blend composition. ON has refined this formula since 1986 with isolate as the lead source rather than concentrate - most value-tier whey leads with concentrate to hit the price point. Third-party-testing credibility and global availability have made Gold Standard the reference daily whey for two generations of lifters.
Gold Standard Whey 1.67kg suits trainees who train 4-6 sessions per week and prefer an established brand over value-tier alternatives, lifters who want isolate-led blends without paying for pure isolate, and athletes who travel internationally and want a globally-available reference product. Contains milk and soy lecithin.
Value alternative: XL Nutrition XTRA Whey 2kg — £34.99 for 66 servings at just £0.53 each (21g protein, 122kcal per 30g scoop). That's roughly 51% less per serving than this product's £1.09/serving cost.
