Optimum Nutrition Gold Standard Whey for everyday protein

Optimum Nutrition Gold Standard 100% Whey is the brand's flagship protein powder and one of the best-selling whey blends in the world. Every flavour delivers 24g of protein per scoop, alongside roughly 5.5g of naturally occurring BCAAs. Energy and the smaller macros shift slightly between flavours, so check the nutrition panel for the one you are buying.

The protein blend leads with whey protein isolate as the primary source, supported by whey protein concentrate and hydrolysed whey peptides for a multi-fraction amino acid spread. Leucine sits at the front of the BCAA ratio for muscle protein synthesis signalling, and the hydrolysed fraction supports faster amino acid delivery after training than a concentrate-only formula.

Size is the only thing that changes between tubs — the formulation and flavour range are identical. The larger formats simply bring the cost per shake down, which matters most if you are running one to two servings a day across a training block. The per-serving price for the size you have selected is shown next to the price above.

Gold Standard suits lifters who want an established, isolate-led whey they can run daily, anyone who rates consistency and flavour spread over chasing the cheapest per-gram protein, and athletes buying into a formula that has been on shelves since 1986. Contains milk and soy lecithin. May contain traces of gluten, egg, nuts and peanuts.

Value alternative: XL Nutrition XTRA Whey 2kg — £34.99 for 66 servings, just £0.53 per shake (21g protein, 122kcal per 30g scoop). Less protein per serving than Gold Standard, but a materially lower cost per shake if you are buying on value.

When should I drink Optimum Nutrition Gold Standard 100% Whey?

How many servings are in a tub of Optimum Nutrition Gold Standard Whey?

That depends on the tub size. At a 31g scoop the 2kg tub gives around 65 servings, the 768g around 25 and the 4.5kg around 145. On a one-shake-a-day routine the 2kg covers roughly nine weeks; at two shakes a day it lasts a little over a month.
