Review of Optimum Nutrition Protein Supplements
Optimum Nutrition is a US-based company, part of Glanbia – an international cheese and nutritional ingredients group. Optimum Nutrition was launched in 1986 with the aim to provide active adults a comprehensive line of protein supplements as well as maintain a high standard of quality across its products. The Optimum Nutrition range is available in some health stores across Australia and online. Let’s see what Optimum Nutrition offers in the protein supplements category.
Optimum Nutrition products
There are many different types of proteins available and the Optimum Nutrition range includes whey, casein, egg and blended options.
Whey Protein Powders
The whey protein powders are Optimum Nutrition’s largest range and include:
- Optimum Nutrition Gold Standard 100% Whey: Uses protein isolates as these are said to be the purest form of whey protein available. There is a large selection of flavours, from key lime pie and birthday cake to coffee and double rich chocolate. There is also a naturally flavoured option available. Gold Standard 100% Whey provides 24 grams of protein per serving. Standard sizes are 1lbs (0.45kg), 1.8 lbs (0.82kg), 2lbs (0.91kg), 3lbs (1.36kg), 5lbs (2.27 kg) and 10lbs (4.54kg).
- Optimum Nutrition Gold Standard Gainer: This is used for protein and carb recovery. The carbohydrate blend includes oat, pea and potato and the fats include flax, chia and medium chain triglycerides. The range has four varieties, including colossal chocolate, cinnamon bun, cookies & cream and vanilla ice cream. The Gold Standard Gainer provides 55 grams of protein per serving. Standard sizes are an option between 5lbs (2.27 kg) or 10lbs (4.54kg).
- Optimum Nutrition Isolate: Made from Whey Isolate, these flavours come in vanilla softserve, chocolate shake, smores and snickerdoodle. These provide 25 grams of protein per serving. Standard sizes of the Isolate are 1.65lbs (0.75kg), 3lbs (1.36kg) and 5lbs (2.27 kg).
There are several other whey protein powders available that you may like to consider for your exercise needs.
Casein protein powders
Whey powder is a faster digesting protein and is used immediately before and after exercise, but slow acting protein, such as casein protein, is used at other times of day, including when your body goes for hours without food. For this type of protein, Optimum Nutrition offers the Gold Standard 100% Casein and the Naturally Flavoured 100% Casein protein powder. Both provide 24 grams of protein per serving. Standard sizes are an option between 2lbs (0.91kg) and 4lbs (1.81kg).
Egg protein powders
Eggs contain essential amino acids and are naturally free of lactose, making the egg protein a great alternative to dairy-based protein powders. For this range, Optimum Nutrition offers its Gold Standard 100% Egg protein powder in chocolate or vanilla custard flavour. It provides 24 grams of protein per serving. Standard size is 2lbs (0.91kg).
Blended protein powders
Blended varieties include the Optimum Nutrition Pro Gainer and the Optimum Nutrition Serious Mass. Optimum Nutrition says that everyone is different and some have a harder time putting on muscle than others. So it created the Optimum Nutrition Pro Gainer with a high-protein formula for post-workout recovery, or as a high-protein shake between meals. The Pro Gainer provides 60 grams of protein per serving. There are four flavours and the standard sizes are 5lbs (2.27 kg) and 10lbs (4.54kg).
The Optimum Nutrition Serious Mass protein powder is designed as a high-calorie weight gainer and has five flavour options. The Serious Mass protein provides 50 grams of protein per serving. Standard sizes are 3lbs (1.36kg), 6lbs (2.72kg) and 12lbs (5.44kg). There are other blended mix options available.
Optimum Nutrition Protein Bars
If you’re looking for something to grab and go, as well as fuel muscle recovery, there are two options in the Optimum Nutrition protein bar range. They are Optimum Nutrition Protein Cake Bites and Optimum Nutrition Opti-Bars.
The Optimum Nutrition Protein Cake Bites are individually wrapped and have frosted coating. They are available in the following flavours:
- Birthday Cake

Optimum Nutrition Opti-Bars are available in the following flavours:
