Optimum Nutrition FAQs
What’s the difference between Gold Standard Whey and Gold Standard Isolate?

Gold Standard Whey is a blend of whey protein concentrate and isolate, offering a balance of taste, mixability, and value. Gold Standard Isolate is more refined, using only isolate for maximum purity — perfect if you’re watching carbs or lactose.

Can I stack ON supplements together?

Absolutely. A popular stack is Gold Standard Whey post-workout, Amino Energy Sparkling for daily energy and hydration, and Creatine to support strength and recovery.

Where are Optimum Nutrition products made?

ON products are manufactured in state-of-the-art, GMP-compliant facilities owned and operated by Glanbia Performance Nutrition in the USA. Quality is tested at every stage.

Are ON supplements Informed Choice certified?

Many Optimum Nutrition products — including Gold Standard Whey and Creatine — are Informed Choice certified, meaning they’re tested for banned substances and safe for sport.

Can I take Gold Standard Whey even if I’m not bodybuilding?

Yes — Gold Standard Whey is great for anyone wanting to support daily protein intake, recovery, and overall wellness. It’s not just for bodybuilders.

Is Amino Energy Sparkling suitable for everyday use?

Yes — it contains natural caffeine from green tea and green coffee, plus essential amino acids. It’s a clean, sugar-free option for energy, focus, and recovery.

How should I take Micronised Creatine Powder?

Mix one rounded teaspoon (5g) with water or your post-workout shake daily. No need to load or cycle. Consistency is key for results.
