Our Ratings and Key Information

Overall Rating

Overall Optimum Nutrition Essential AmiN.O. Energy is more of a mild/beginner friendly pre-workout supplement that brings in essential ingredients but in very low doses.


Ingredients: Citric Acid, Malic Acid, Natural & Artificial Flavors, Inulin, Beet Powder, Tartaric Acid, Energy Blend (Caffeine, Green Tea Extract, Green Coffee Extract), Silicon Dioxide, Calcium Silicate, Sucralose, Gum Blend (Cellulose Gum, Xanthan Gum, Carrageenan), Lecithin, FD&C Yellow #5&6.


The dosages on a lot of the ingredients are on the lower side per serving. Best suited for those looking for something less intense than the usual product on the market.


Optimum Nutrition is a good supplement brand that provides a lot to the community. However this product has too many extra ingredients that we are not fans of.

Things like Sucralose, Gum Blend (Cellulose Gum, Xanthan Gum, Carrageenan), Lecithin, and FD&C Yellow #5&6 limit this products overall quality rating when compared to products that don’t use these types of ingredients.
