NITROSURGE Nutrition & Ingredients

There’s no calorie information, but one scoop has l-citrulline (2g), beta alanine (1.6g), betaine anhydrous (1.25g), theanine (90mg), hordenine HCI (25mg), and BioPerine® or black pepper extract (2.5mg). There’s also 180mg of caffeine per scoop, about as much as you’ll find in two cups of coffee.

The other ingredients are mostly natural and artificial flavors and sweeteners. While the product does have the sweeteners sucralose and acesulfame potassium, which are controversial in some circles, the coloring is natural and made from fruit and vegetable juice.

NITROSURGE Benefits and Effectiveness

What do these ingredients do? Jacked Factory seems to have done their research. They’ve included some of the most common preworkout ingredients and they have a large amount of research supporting their effects.

The beta alanine has a strong link with endurance while the betaine anhydrous is a common supplement for increasing power. The citrulline may also increase power, but it’s more commonly used for increasing blood flow and circulation. The theanine is often included with supplements containing caffeine because it’s known to reduce the jitteriness and lack of focus that can accompany a big caffeine hit. The BioPerine is there because it may help all of the ingredients absorb more effectively.

There’s not a lot of research into the hordenine. It’s a molecule found in a variety of plants and there’s promising evidence that it could increase fat loss and have adrenaline-like effects, thereby improving workout performance. But there haven’t been a ton of studies and there’s no consensus yet on what could constitute an effective dose.

By and large, the dosages used seem pretty well supported by evidence with the exception of the two grams of citrulline, which studies suggest should be dosed at closer to six grams for an acute effect on a workout.


You can pick up 30 servings for $24, so around 80 cents per serving. That’s pretty reasonably priced; most preworkouts are between 80 cents and $1 per serving.


I tried out the Cherry Limeade flavor. It was pretty refreshing, though I can’t say I tasted much of the lime — the flavor was mostly like maraschino cherry.

The Takeaway

It’s reasonably priced, has a solid amount of caffeine, and almost all of the extra ingredients are research-backed and well-dosed. I wasn’t that impressed by the hordenine or the citrulline but for 80 cents a serving, you definitely get your money’s worth with NITROSURGE.

Per Serving: $0.80

I’m a journalist and content producer with over seven years' reporting experience on four continents, with most of that spent covering health-related issues. My resume includes covering cholera outbreaks in Kenya and the clubbing scene in Shanghai, which is also where I wrote my first ever health article for an English language magazine. (It was on diarrhea.)After returning to Australia to finish up degrees in Journalism and International Relations I wound up in New York City where I’ve worked for Men’s Health, VICE, Popular Science and others. I try to keep health relatively simple — it’s mostly vegetables and sweat — but I live to explore the debates, the fringes, the niche, and the nitty gritty.
