How It Works
Optimum Nutrition Gold Standard 100% Isolate undergoes a rigorous multi-step purification process. It begins with high-grade Whey Protein Isolate, which is then partially broken down through hydrolysis into smaller chains of amino acids (peptides). This enables your digestive system to absorb and utilise the protein at an accelerated rate compared to standard whey protein concentrates.
By rapidly shuttling essential building blocks directly into depleted muscle cells, this formula helps accelerate the recovery window following intense exercise. With zero unnecessary fillers and less than 1g of sugar per serve, it provides pure, clean fuel that fits seamlessly into low-carb, high-protein nutrition plans.
Recommended Use
Mix 1 level scoop (approx. 30g) into 200–250ml of cold water, low-fat milk, or your preferred beverage in a shaker cup. Shake or stir for 20–30 seconds until fully dissolved.
-
Post-Workout: Consume within 30–60 minutes following your workout to accelerate muscle repair.
-
Daily Protein Supplementation: Take first thing in the morning or between main meals to help satisfy daily protein requirements.
Optimum Nutrition Gold Standard 100% Isolate Frequently Asked Questions
What is the difference between Gold Standard 100% Whey and Gold Standard 100% Isolate?
While Gold Standard 100% Whey uses a blend of Whey Protein Concentrate (WPC), Whey Protein Isolate (WPI), and Whey Peptides, Gold Standard 100% Isolate uses strictly WPI and Hydrolysed WPI. This results in a higher protein percentage per serve with lower fat, carbohydrate, and lactose levels.
Is Optimum Nutrition Gold Standard 100% Isolate suitable for people with lactose sensitivity?
Because whey protein isolate undergoes extensive filtration to strip out nearly all fats and sugars, the lactose content is extremely minimal (less than 1g of sugar per serve). Many individuals who experience mild stomach discomfort from standard whey concentrates find this isolate far easier to digest.
How many servings are in the different container sizes?
Depending on your training frequency and budget, Sprint Fit stocks three distinct sizes:
720g (1.58lb) Tub: Provides 24 full servings (perfect for trying out premium flavors).
1.36kg (3lb) Tub: Provides 44 full servings.
2.28kg (5.02lb) Tub: Provides a massive 76 full servings (offering the best cost-per-serve value for daily trainers).
Is this protein powder safe for drug-tested, competitive athletes?
Absolutely. Optimum Nutrition Gold Standard 100% Isolate is proudly Informed-Choice certified. Every single production batch is independently screened and tested for banned substances, ensuring elite competitive athletes across NZ can trust its safety and complete label accuracy.
Can I mix Gold Standard Isolate without a shaker bottle?
Yes, the powder is fully instantized. This means it dissolves effortlessly into cold water, milk, or a smoothie base with a simple stir of a spoon, leaving absolutely zero gritty residue, lumps, or chalky texture behind.

Rich Vanilla
Love this product. Not heavy at all and doesn't give you that bloated feeling a lot of protein powders give. I've been having it in my daily smoothies and ive lost 9KGs, its the only part of my diet and exercise routine that ive changed so its definitely works well as a part of a balanced diet. Very smooth, dissolves easily and doesn't leave a milky taste. Vanilla is definitely my favorite and goes with everything - unfortunately it was out of stock so had to try the chocolate, took a while to get used to the taste but otherwise great as well. Definitely recommend.

Really clean tasting shake. Not too sweet, the chocolate is more of a creamy icecream flavour rather than a rich style chocolate taste. Sits on my tummy well and has definitely boosted my weight loss while maintaining my muscle mass already after one week of daily shakes
