Optimum Nutrition is one of the most recognized names in sports nutrition, and it remains a staple brand at Fuel Supplements. The lineup here centres on Gold Standard 100% Whey — available in 1.5 lb, 2 lb, 5 lb and 10 lb sizes — alongside Gold Standard Whey Isolate, Amino Energy, ON Creatine Monohydrate, and mass gainers like Serious Mass and Pro Complex Gainer. If you prefer grab-and-go, the Gold Standard ready-to-drink shakes and the 40 g Protein Shake RTD are popular with customers who want protein without mixing.

Optimum Nutrition FAQ & Buying Guide

What are Optimum Nutrition's most popular products at Fuel Supplements?

Gold Standard 100% Whey in the 2 lb and 5 lb tubs is the consistent best seller, followed by the Gold Standard ready-to-drink shakes, Amino Energy, and the mass gainers (Serious Mass and Pro Complex Gainer). ON Creatine Monohydrate is a common add-on since it stacks easily with any protein.

What is Optimum Nutrition known for?

Primarily whey protein — Gold Standard 100% Whey is one of the most widely used protein powders in the world. The brand also covers pre- and intra-workout aminos (Amino Energy), creatine, and calorie-dense gainers, so you can build most of a basic stack from one brand.

Should I choose Gold Standard Whey or Gold Standard Isolate?

The standard 100% Whey is a whey blend with a bit more fat and carbs per scoop and a lower price per serving. The Isolate is filtered further for a leaner macro profile, which some people with sensitive stomachs also find easier to digest. Both support muscle recovery after training.

Is Optimum Nutrition available in Canada?

Yes — Fuel Supplements stocks Optimum Nutrition in Canada and ships Canada-wide from our BC warehouses. Orders over $100 ship free, and same-day pickup is available in Port Coquitlam, BC.
