7.9Overall Score

Optimum Nutrition released Protein Energy, a protein powdered supplement that also includes caffeine from natural sources.

This is an interesting niche to be in, as it blends together post-workout and pre-workout aspects, albeit in smaller doses and fewer ingredients, to offer additional energy and protein amounts throughout the day, regardless of whether it is a training day or not.

We’re going to take a closer look at the information available to see if Protein Energy is indeed something worth trying.

Ingredient Analysis

Optimum Nutrition Protein Energy will provide 10 g protein in the form of whey protein concentrate, isolate, and hydrolysate.

There is also an Energy and Focus Blend of 110 mg that includes caffeine and Green Tea Extract, which are ingredients that are found in energy-boosting supplements.


Protein Energy provides only 1 g carbohydrates and 50 calories per serving, which is great for individuals who looking to consume more protein and are possibly looking for a boost of energy, without consuming a lot of calories.

Flavor Options, Availability & Pricing

Optimum Nutrition Protein Energy is available in 4 flavors:

• Chocolate
• Vanilla Latte
• Cinnamon Bun
• Mocha Cappuccino

My favorite flavors were cinnamon bun and chocolate. Also, for fans of vanilla, the vanilla latte flavor offers a refreshing spin on the traditional flavor.

I had to experiment with optimal liquid amounts to achieve the flavor that I wanted. Overall, Protein Energy had a good taste. There wasn’t any bitter or weird after-taste, which is plus.

A bag of Protein Energy retails for around $29.99 and provides 52 servings.The price-to-serving ratio isn’t terrible. One serving essentially costs about $1.73.

As far as energy goes, I noticed a subtle boost. It was nothing crazy, just a nice little boost. The amount of caffeine in the Energy and Focus Blend, to me, however, isn’t enough to make Protein Energy my sole pre-workout supplement. It’s moderately dosed protein and energy content makes it stackable with other supplements. Just make sure to watch your overall caffeine intake.

While Optimum Nutrition Protein Energy doesn’t offer optimal amounts of protein and energy to make it your sole pre- and post-workout supplement, it does lend itself as a great aid for those looking to step up their day-to-day performance and even workout recovery.
