Description

inforgraphic about Gold Standard Isolate

Gold Standard 100% Isolate by Optimum Nutrition is a premium whey protein isolate built for fast, clean recovery. Each serve delivers 25g of protein at around 80% purity, drawn entirely from whey protein isolate that has been ultra-filtered to strip out excess fat, cholesterol and sugar. A portion is then hydrolysed, broken into smaller amino acid chains for faster digestion, making this one of the leanest, fastest-absorbing proteins Optimum Nutrition makes. Explore all of our Whey Protein Isolate options here.

With less than 1g of fat and just 1g of carbs per serve, it is a low-calorie, high-purity protein suited to lean nutrition plans and anyone wanting maximum protein with minimal extras. Like the rest of the Gold Standard range, it is instantised for easy mixing, Informed Choice certified and banned-substance tested on every batch. Compared with Gold Standard 100% Whey, the Isolate is more highly filtered, so it is purer, leaner and lower in lactose. For a complete routine, pair it with daily Creatine Supplements, Pre-Workout Supplements before training, and Glutamine or EAAs on harder or fasted sessions.

Benefits of Gold Standard 100% Isolate:

25g of protein per serve at approximately 80% purity
Made entirely from ultra-filtered whey protein isolate, with a portion hydrolysed for faster absorption
Less than 1g of fat and 1g of carbs per serve
5.5g of naturally occurring BCAAs and 4.3g of naturally occurring glutamine and glutamic acid per serve
Instantised for easy mixing
Informed Choice certified, banned-substance tested and gluten free

When you want the cleanest, fastest-digesting protein in the Gold Standard range, Gold Standard 100% Isolate delivers exactly that. Shop now at Nutrition Warehouse.

FAQs

What's the difference between Gold Standard 100% Isolate and Gold Standard 100% Whey?

<a href='https://www.nutritionwarehouse.com.au/products/gold-standard-100-whey-by-optimum-nutrition' title='Shop Gold Standard 100% Whey'>Gold Standard 100% Whey</a> is a whey blend led by whey protein isolate and supported by whey protein concentrate, making it a great-value everyday protein. Gold Standard 100% Isolate is made entirely from isolate and is more highly filtered, so it is purer, leaner and lower in fat, carbs and lactose. Choose the Isolate for the leanest, fastest-digesting option, and the Whey for a quality all-rounder at a more accessible price.

Is Gold Standard 100% Isolate good for fast absorption?

Yes. Because it is made from ultra-filtered isolate with a portion hydrolysed into smaller amino acid chains, it digests quickly, which makes it well suited to the period straight after training when fast protein delivery is useful.

How do you use Gold Standard 100% Isolate?

Add one scoop to 180 to 240ml of cold water or milk and shake for around 30 seconds until mixed. Have it within 30 to 60 minutes of training, or any time of day to help reach your protein target. Most people use one to two serves daily depending on their goals and how much protein they get from food.

Is Gold Standard 100% Isolate gluten free?

Yes, it is gluten free. It does contain milk and soy (soy lecithin), so it is not suitable if you need to avoid dairy or soy.

What does Gold Standard 100% Isolate stack well with?

<a href='https://www.nutritionwarehouse.com.au/collections/creatine' title='Shop Creatine Supplements'>Creatine supplements</a> are one of the most researched pairings for strength and size goals and work through a different mechanism to protein. A <a href='https://www.nutritionwarehouse.com.au/collections/pre-workout' title='Shop Pre-Workout Supplements'>pre-workout</a> taken around an hour before training covers energy, focus and pumps, while standalone <a href='https://www.nutritionwarehouse.com.au/collections/amino-acids' title='Shop Glutamine and EAAs'>glutamine or EAAs</a> can be useful intra-workout or during fasted training on harder days.

What sizes does Gold Standard 100% Isolate come in?

It is available in three tub sizes: around 720g to 744g (24 serves), 1.32kg to 1.41kg (44 serves) and 2.28kg to 2.36kg (76 serves). Exact tub weights vary slightly by flavour. Compare it with other <a href='https://www.nutritionwarehouse.com.au/collections/whey-protein-isolate' title='Shop Whey Protein Isolate'>whey protein isolate</a> options in our range.

Directions

Mix one scoop of Gold Standard 100% Isolate with 180–240mL of cold water or beverage of choice. Consume immediately after training or as needed to meet your protein requirements. This product is intended for healthy adults; always read the label, use only as directed, and seek medical advice if unsure.
