Manufactured as three vegan-friendly HPMC capsules per serving, the product is made without artificial fillers or unnecessary additives for easy pre-workout dosing.

Frequently Asked Questions

Got questions? We’ve got answers!

Why does beEnergy contain caffeine?

Caffeine has demonstrated its effectivness at reducing fatigue, time to exhuastion, muscle performance, agility and reducing muscle pain. Put simply, it helps you perform stronger.

Is red spinach extract more potent than beet?

Red spinach extract has a very high concentration of natural nitrates when compared to beet powders or juices.

How long before I see results?

Take beEnergy approximately 45-30 minutes before training or racing to feel the benefits.

Is it safe to take every day?

beEnergy is safe to use every day, but be aware of the high caffeine content. If you are sensitive to caffeine, you could spread the capsules out over a longer period of time.

How much caffeine is in beEnergy?

We have included 235mg of caffeine per dose. One dose consists of 3 capsules.

Why have you included red spinach extract?

Red spinach extract is extremely rich in natural nitrates, which are converted into nitrites and then nitric oxide in the body.

What's so good about red spinach extract?

Red spinach extrcat found in beEnergy has a wealth of benefits for the athlete. These include improved cardiovascular function that leads to better athletic performance, but is also rich in essential nutrients that contribute to muscle repair and growth. It is also rich in antioxidants to fight free radical damage and inflammation.

Other products contain more ingredients, so why doesn't yours?

We align our products with the recommendations issued by the American College of Sports Medicine. They state that nitrates and caffeine improve performance, so that's what we've stuck with.

Isn't a Redbull or Monster better?

Those are fizzy (carbonated) caffeinated drinks. They do not improve nitric oxide production and are not ideal to drink before running due to the gassy effects they can have.
