Directions for use

Mix 1 scoop of Optimum Nutrition Gold Standard 100% Whey protein in 200ml of chilled water or milk and consume immediately after a workout and/or throughout the day as a high-protein snack.

We recommend consuming whey protein as part of a well-balanced, healthy diet. For optimal results, spread your protein allotment throughout the day and ensure you're getting a protein source from each meal.

Taste and mix

No matter how beneficial a whey protein supplement is for your health, if it tastes bad or if the textures just not quite right - you're not going to want to drink it.

That's why Optimum Nutrition took their time curating this exclusive blend.

Gold Standard 100% Whey protein is a truly sensational formula, with flavours that are simply to-die-for. Our most popular flavours in ON Gold Standard 100% Whey are french vanilla ice-cream, rocky-road, peanut butter, double-rich chocolate, milk chocolate, salted caramel and white chocolate.

Plus, Gold Standard 100% Whey protein can be mixed super-easily. Simply stirring your protein with a spoon will do the trick - no bits, clumps or a gritty texture (like most whey protein powders that require a blender).

Gold Standard Whey is also low in lactose. This makes it much safer for people suffering from lactose intolerance (however, we do recommend using a plant-based protein if this is an issue for you). 

Why is whey protein important?

Whey protein is the most important nutrient for both gaining and maintaining muscle. 

Proteins are the building blocks in the body. They're in charge of building and repairing tissue in the muscle, bone, cartilage, blood and skin. Protein is considered a macronutrient, which means the body needs to consume large quantities of it.

If you're exercising regularly, you're going to need extra nutrients to support your body when recovering - otherwise, your muscles won't heal and repair properly and they simply will not get any bigger or stronger.

However, relying on food alone isn't enough. It's nearly impossible to consume the right amount of protein-rich foods to sufficiently fuel the muscle-building process.

Gold Standard Whey protein, on the other hand, is an excellent supplement you can add to your dietary regime, to enhance growth and recovery. Whey protein is commonly consumed in a 'shake' formula, but you can also add whey protein powders to food such as pancake batter, oats, or rolled into bliss balls - yum!

Optimum Nutrition Gold Standard 100% Whey protein has an impressive protein content and is perfect for anyone looking to pack on lean muscle mass. With 24 grams of protein and 5.5 grams of BCAA's in every scoop, this formula has everything you need to accomplish your goals.

Optimum Nutrition Gold Standard 100% Whey protein is fast-absorbing and can be digested pretty quickly (thanks to the high amount of whey protein isolates for maximum absorption) - this makes it the ultimate pairing for post-workout consumption.

The science behind Gold Standard Whey

Optimum Nutrition Gold Standard is made using ion-exchange whey protein. 

This is a common filtration process used by manufacturers when creating whey protein powder supplements. Milk protein starts off as a combination of 80% casein and 20% whey, which then needs to be separated to make an end-product which is made of entirely pure ingredients.

There are a few different ways to process the milk, but ion exchange is ideal for developing a form of whey protein which is low in fat and lactose and incredibly high in whey proteins.

The experts at Optimum nutrition have used a mixture of whey protein isolates and whey protein concentrates - two high-quality and fast-absorbing forms of protein.

Optimum Nutrition ensures the proteins are measured carefully within each batch for a consistent and powerful protein blend providing you with lean muscle growth and muscle recovery.

What are the benefits of whey protein?


Not only will whey protein help you gain muscle, but it'll also help to reduce any soreness the next day, after an intense gym session. Helping your muscles recover quicker, means you can get back to the gym the following day without the nasty aches and pains getting in the way.

Hunger and cravings 

Taking Optimum Nutrition Gold Standard Whey protein will also help to satiate your hunger and keep you feeling fuller for longer throughout the day - which will also help prevent snacking in-between-meals. If you workout first things in the morning, we recommend having a protein shake right before bed to reduce that empty feeling in your stomach when you first wake-up - so that you can power through your training session without feeling starved!

Can whey protein make you gain weight?

When used as a part of a well-balanced and healthy diet, Gold Standard 100% Whey protein won't make you gain weight. However, if you're on a calorie surplus (consuming more calories than you're burning as energy) then you will gain weight over time.

Simply put, depending on what your goal is, you need to make adjustments to your calorie intake.

If you're looking to gain mass, you can bump-up the calories in your Gold Standard Whey protein shake by using dairy-based milk, adding banana, oats, nut butter, avocado or even honey.

If you're looking to lose weight, look at counting your calories throughout the day (we recommend using the MyFitnessPal app) to ensure you're not exceeding your recommended daily macros and you should see a weight reduction over time.
