FAQs
Optimum Nutrition Gold Standard 100% Isolate Frequently Asked Questions
What makes Gold Standard 100% Isolate different from standard Gold Standard Whey?
The main difference is the level of purity and digestion speed. While standard Gold Standard Whey is a blend of isolate, concentrate, and peptides, Gold Standard 100% Isolate undergoes a series of sophisticated filtration processes to "strip away" excess fats, cholesterol, and sugars. The result is a highly purified, ultra-fast digesting formula composed strictly of premium Whey Protein Isolate.
How many grams of protein, carbs, and fats are in a serving? Every standard 30g scoop delivers an ultra-clean macronutrient profile designed for lean muscle goals:
Protein: 25g of pure hydrolyzed and filtered Whey Protein Isolate.
Carbohydrates: Less than 1g (including less than 1g of sugar).
Fats: Less than 1g per serving.
Amino Acids: 5.5g of naturally occurring Branched-Chain Amino Acids (BCAAs) to kickstart recovery.
Is Gold Standard Isolate suitable for people with lactose sensitivity?
Yes. Because it goes through advanced microfiltration steps to isolate the pure protein, the vast majority of lactose and fat is removed. If you experience regular bloating or a sensitive stomach from standard dairy-based protein blends, this clean isolate formula is an exceptional alternative that digests incredibly smoothly.
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.
What are the top-rated Gold Standard Isolate flavors in NZ?
Because it is a highly filtered isolate, the consistency is lighter and thinner than traditional shakes. The top-rated flavors among Kiwi fitness enthusiasts include Chocolate Bliss (which mixes perfectly like a smooth chocolate milkshake), Chocolate Honeycomb, and Rich Vanilla.
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.
