Frequently Asked Questions

Optimum Nutrition is a global sports nutrition brand known for whey protein, mass gainers, pre-workouts, creatine and vitamins.

Who are Optimum Nutrition?

Optimum Nutrition is one of the biggest names in sports nutrition, best known for Gold Standard 100% Whey Protein. The brand also produces mass gainers, pre-workouts, creatine, amino acids and vitamins, making it a genuine all-round supplement range rather than just a protein specialist.

What is Optimum Nutrition best known for?

Optimum Nutrition is best known for Gold Standard 100% Whey, one of the most widely used whey proteins in the world. It is also well known for Serious Mass, a high calorie gainer used by people looking to bulk up, and for its Opti-Men multivitamin range.

What is the best Optimum Nutrition protein powder?

The best choice depends on your goal. Gold Standard 100% Whey is the classic all-rounder for building and maintaining muscle, Gold Standard 100% Isolate suits those wanting a leaner protein with less fat and carbs, and Serious Mass is aimed at people trying to add size and calories. Clear Whey Isolate + Collagen is a lighter, juice-style option for those who find shakes too heavy.

Does Optimum Nutrition make pre-workout supplements?

Yes, Optimum Nutrition offers Gold Standard Pre-Workout and Platinum Pre Workout Pump for training energy and focus, alongside Amino Energy for a lighter energy and recovery boost. Gold Standard BCAA is also popular for supporting recovery around training.

Are Optimum Nutrition products suitable for vegans?

Most Optimum Nutrition products contain dairy or animal derived ingredients, but the brand does cater for plant based diets. Clear Plant Protein Isolate and the Vegan Stack are formulated without animal ingredients, giving vegan customers a genuine Optimum Nutrition option.
