Understanding common misspellings of “guarana”
People often search for guaranna, guaranaaa, guarana seed, garana, guarana drink. We use “guarana powder drink” in our pages to help you find the right info.
How much caffeine is in Mana Rush? Is 200 mg a lot?
About ~200 mg per 5 g scoop. Many health guidelines suggest healthy adults stay around ≤ ~400 mg/day from all sources. Sensitivity varies—start with ½ scoop if you’re new to guarana or caffeine.
How do I mix it? When do I take it? How long does it last?
- Add 5 g (1 scoop) to 12–16 oz cold water.
- Stir or shake; wait 2–3 minutes; add ice. Optional: citrus or sparkling water.
- Timing: many people use it in the morning, mid-afternoon, or 20–30 min before training.
Most feel alert within 10–20 minutes; duration varies by person, sleep, and nutrition. See more ideas on our recipes page.
Do I get the jitters? Will I crash? How does it make you feel?
Caffeine can cause jitters or sleep disruption for some, especially at higher doses. Powder lets you control the dose (½ scoop is a great start). Many customers describe a clean, steady lift with no heavy syrups or artificial sweeteners.
Guarana vs coffee & energy drinks • Shots vs powder
- Coffee vs guarana: similar alertness. Guarana powder is portable and easy to dose (½ or full scoop).
- Canned energy drinks: convenient but fixed sugars/sweeteners. With powder, you pick the strength and liquid.
- Shots vs powder: shots are “situational”; powder is the flexible daily driver. See our comparison.
- SRG vs Red Bull: SRG relied on guarana extract; RB uses taurine + sugar/sweeteners. Taste and format differ.
Working out, bodybuilding & nootropic questions
Pre-workout: ½–1 scoop in water 20–30 minutes before activity is common. People use guarana for perceived effort, consistency, and focus.
Nootropic intent: caffeine can support alertness/attention. Pair with sleep, hydration, and nutrition for best results.
What’s inside? Flavors, storage, sourcing

Storage: keep sealed in a cool, dry place away from heat/sun.
