Made by Gabe + Wendi · Kāneʻohe, Oʻahu
I discovered guarana while traveling, and it changed how I thought about convenient caffeine. I came home to Hawaiʻi and began developing a water-mixable guarana powder with my partner Wendi.
Mana Rush is still made in small batches on Oʻahu with a short, clearly labeled ingredient list. We track the guarana lots used in production.

I got the Lemon Grass and the Lemon Lilikoi. Both were great, and noticed the caffeine immediately. Nothing crazy, just a bit more alert. Excited to try the Lime next! Great product!

Mangosteen tastes great
Mangosteen tastes great, I’m usually on the go. Still worth the price since this batch lasted a lot longer than the shots. Thanks Wendy

Mana Rush Guarana Mangosteen – Exotic Fruit Energy
Best long lasting energy
Best energy and focus without the crash that caffeine has. One drink last all day and is far less expensive than buying energy drinks.

See the flavor guide →Common questions about Mana Rush energy powder
What is a natural energy drink powder?
A natural energy drink powder is a concentrated mix that you add to water yourself. Mana Rush uses guarana as its caffeine source, fruit-based flavor ingredients, and stevia. Because it is a powder, you are not paying to ship water in a can and you can choose how much water to use.
How does Mana Rush compare with canned energy drinks?
Mana Rush is a zero-sugar powder with caffeine from guarana. Many canned energy drinks use a different combination of caffeine, sweeteners, flavors, and other ingredients. The best choice depends on your caffeine tolerance, preferred ingredients, taste, and serving size.
How much caffeine is in one serving?
A full Mana Rush serving contains about 200 mg of caffeine. Caffeine sensitivity varies, so begin with less than a full serving when appropriate, do not combine it with other high-caffeine products, and avoid taking it close to bedtime.
Did Mana Rush used to come as a guarana shot?
Yes. The earlier product was a ready-to-use guarana shot. Mana Rush is now sold as a powder because it is easier to ship, store, and mix with the amount of water you prefer. For a smaller drink, mix the recommended serving with less water; the caffeine amount does not change unless the amount of powder changes.
Who should limit or avoid Mana Rush?
Mana Rush is intended for adults who already tolerate caffeine. Children, people who are pregnant or nursing, people who are sensitive to caffeine, and anyone advised to limit stimulants should avoid it or ask a qualified healthcare professional first.
Hawaiʻi-made guarana energy powder
Mana Rush is a zero-sugar energy drink powder for adults looking for a portable alternative to coffee and canned energy drinks. Guarana supplies the caffeine, fruit-based ingredients provide flavor, and the powder mixes with cold water in about 30 seconds.
A full 5 g serving contains about 200 mg of caffeine. That is a substantial amount, so serving size and timing matter. People who are new to the product or sensitive to caffeine should begin with less, avoid combining it with other high-caffeine products, and keep caffeine away from bedtime.
Use Mana Rush with cold water, sparkling water, smoothies, or lemonade. The amount of water changes the flavor strength, while the amount of powder determines the caffeine dose. Each 8 oz pouch provides approximately 45 full servings.
Explore the available flavors, compare guarana and coffee, read the energy powder guide, review the guarana FAQ, or use the flavor guide.
Mana Rush developed from an earlier ready-to-use guarana shot into a powder format. The current format is easier to store and ship, and it lets customers choose the amount of water they prefer while following the labeled powder serving.
