Optimum Nutrition Gold Standard 100% Isolate is a premium isolate with 100% of its protein from whey: hydrolyzed whey protein isolate and whey protein isolate. Extra filtration keeps fat and carbs to a minimum — ideal when cutting or tracking calories closely. Each 30 g serving gives 25 g of protein, 1 g of carbs and only 100 kcal. One tub provides 44 servings. Rich Vanilla is a rich, clean vanilla taste — 0 g fat and only 100 kcal per serving, the leanest option. Gluten free and banned-substance tested. Fast-absorbing hydrolyzed isolate makes it a great post-workout choice, and many find it lighter on the stomach than concentrate.

Mix 1 scoop (about 30 g) with 180–240 ml (6–8 fl oz) of cold water. Shake until dissolved. Use after training or throughout the day to meet your protein needs. Combine with high-protein foods to reach your daily protein target.
