It comes from the Amazon and looks like an eyeball, but what is guarana? And what can it do for your health?
6 REASONS WHY YOU WANNA EAT GUARANA
Updated: 2026-01-29
GUARANA THE ENERGIZING SUPERFOOD WITH AMAZING HEALTH BENEFITS
Have you heard of guarana?
If you haven’t, and you’ve had at least one energy drink in your life, there’s a good chance you’ve consumed it.
While guarana is predominantly used in the beverage industry for its caffeine content, there’s a lot more to this eyeball-looking superfood than you may think!
WHAT IS GUARANA?
Guarana or Paullinia cupana is a climbing plant native to the Amazon. It belongs to the soapberry family, which includes lychee.
The word guarana comes from the Tupi-Guarani word warana, which means “fruit like the eyes of the people.” That’s because the plant produces coffee bean-sized fruit that contains a black seed surrounded by white flesh, which gives it the appearance of an eyeball.
When it comes to the taste of guarana seeds, they’re extremely bitter. This is why we add lucuma and banana to our Energy Bomb mix to balance out the bitterness from the guarana.
GUARANA: A NATURAL SOURCE OF CAFFEINE
This Amazonian fruit has been used for centuries by Brazilian tribes for its healing and energy-boosting properties.
When it comes to its antioxidant profile, guarana is similar to green tea: it’s rich in catechins, saponins, theobromine and tannins.
What makes guarana so popular is its natural caffeine content. Up to 6% of the seed contains caffeine and it’s 4-6 times more potent than coffee beans.
Because of this, guarana is a common ingredient in sports and energy drinks. In fact, 70% of guarana is used by the beverage industry. The other 30% is used to make guarana powder.
6 REASONS WHY YOU WANNA EAT GUARANA
Here’s why you should be eyeing this berry and incorporating it into your diet.
GUARANA IS A NATURAL ENERGY BOOSTER
Feeling tired? Don’t reach for coffee — reach for guarana instead!
The caffeine in guarana works similarly to other caffeinated beverages by blocking adenosine, a neurotransmitter that relaxes the brain and makes you feel tired.
However, unlike coffee, guarana is released slowly, giving you long-lasting energy.
On top of reducing physical fatigue, one study showed guarana also improves mental fatigue.
GUARANA MAY PROTECT AGAINST CANCER
While more research is needed, there are some promising studies that show guarana’s anti-cancer effects.
So far, studies show guarana protects against DNA damage, suppresses cancer cell growth and induces cancer cell death.
Why is this? Researchers hypothesize its due to the xanthines in guarana, which are compounds that are similar to caffeine and theobromine.
GUARANA IMPROVES YOUR ABILITY TO LEARN
Like matcha, guarana has some serious brain-boosting benefits.
A 2007 study published in the “Journal of Psychopharmacology” tested the behavioral effects of guarana on humans. The results showed participants who received 37.5mg or 75mg of guarana “produced more positive cognitive effects.” However, while caffeine may play a role, researchers don’t think it’s the only reason why participants did better.
A slightly earlier study published in 2004 also showed participants who received guarana extract paid more attention to their tasks and completed them faster.
GUARANA’S GOOD FOR YOUR HEART
If you’re looking for a heart-healthy food, look no further than guarana. This Brazilian berry benefits the heart in two ways.
First, guarana can reduce the risk of heart attack and stroke by preventing blood clots. Research points to the caffeine and catechins for the “anti-platelet aggregatory activity.”
The second way guarana can benefits the heart is reducing plaque build-up in the arteries by decreasing the oxidation of bad cholesterol.
GUARANA MAY BE GOOD FOR YOUR SKIN
We all know wearing sunscreen is a great way to protect our skin from harmful UV rays, but caffeine can help too!
Studies show caffeine’s antioxidant properties protect cells against the UV radiation and shows anti-aging properties by slowing down the process of photoaging of the skin.
GUARANA MAY PROVIDE PAIN RELIEF
Did you know most over the counter pain medicines contain caffeine? It also improves their effectiveness by 40%!
How is that possible? Because caffeine binds and blocks adenosine receptors (remember those?), two of which are responsible for stimulating the feelings of pain.
Due to guarana’s high caffeine content, it could be beneficial when it comes to pain relief.
HOW TO START ADDING GUARANA TO YOUR DIET
As we mentioned before, a majority of the guarana used today is in energy and sports drinks. But have you ever read the ingredients on an energy drink? It’s nothing but hard to pronounce words and questionable (chemicals and synthetic) ingredients that were sourced from who knows where.
If you’re looking for a safer and cleaner way to enjoy guarana, we suggest trying our Mana Rush Guarana Shots! It’s a healthier alternative to coffee — in fact, 1 serving is the same as a cup of coffee! I also like taking Energy Bomb before a workout.
We source our organic guarana powder from Brazil where the guarana seeds are sun-dried and roasted at low temperatures.
Not only will you get all that natural guarana goodness, you’ll also get the added benefit of all other benefits from this superfood!

Adenosine, Caffeine, and Sleep: The Science of When to Start — and When to Stop
If caffeine sometimes “stops working,” keeps you up too late, or makes you crash at the wrong time — adenosine is usually the missing piece. This is a scientific, educational guide to: When you understand adenosine, you can make caffeine work with your body instead of against it. Adenosine is a molecule your body produces naturally as part of energy metabolism. As you stay awake and use energy throughout the day, adenosine gradually accumulates in the brain. As adenosine levels rise, they bind to adenosine receptors (often described as A1 and A2A receptors), which increases the feeling we call sleep pressure — that heavy, foggy sense that builds when you’ve been awake for a long time. In simple terms: Adenosine isn’t a “bad thing.” It’s part of the system that helps your brain track how long you’ve been awake and pushes you toward recovery. That’s why you often feel: Sleep clears adenosine pressure, which is one reason good sleep can restore morning alertness. Caffeine doesn’t “create energy.” The core mechanism is that it blocks adenosine receptors. Think of it like this: So you feel more awake, not because adenosine disappeared, but because the brain can’t read the signal as strongly. Because caffeine blocks receptors temporarily, adenosine can continue accumulating behind the scenes. When caffeine wears off, you may suddenly feel the full weight of your accumulated sleep pressure — which people describe as a crash, fog, or slump. This is one reason timing and dosing matter more than people realize. Many people do best by waiting a little after waking before taking caffeine. Early morning alertness is often supported by your natural circadian hormones, and delaying caffeine can reduce the “need” to keep escalating later. Practical approach: consider caffeine after you’ve been awake for a bit, once your morning routine is underway. If you’re using caffeine continuously from morning until evening, you’re often fighting a rising adenosine load. A healthier strategy is to set a “support window” for caffeine (work block, workout block, long drive) rather than constant intake. Sleep quality strongly influences tomorrow’s adenosine pressure and alertness. Many people benefit from a firm caffeine cut-off time earlier in the day so caffeine is less likely to interfere with falling asleep. Practical approach: choose a cut-off that protects your bedtime and stick with it consistently. When energy dips, the instinct is to add more caffeine. But that can push your cut-off later and disrupt sleep — which increases the next day’s adenosine pressure and repeats the cycle. Better approach: use smaller, intentional servings and pair them with hydration, movement, and food timing. This keeps caffeine aligned with adenosine biology rather than battling it. When people talk about “clean energy,” they often mean: Understanding adenosine helps you get there — because timing caffeine well is often more important than simply increasing the dose. Adenosine is a molecule that builds up in the brain the longer you’re awake. It creates sleep pressure and helps signal when it’s time to rest. No. Caffeine blocks adenosine receptors temporarily, which reduces the feeling of sleepiness without removing adenosine itself. As adenosine continues to build up, blocking the signal becomes less effective. When caffeine wears off, the accumulated sleep pressure can feel like a crash. Many people benefit from waiting until they’re fully awake and beginning their main work or training block rather than taking caffeine immediately upon waking. Stopping caffeine early enough to protect sleep is critical. Sleep is what resets adenosine pressure for the next day. Not always less, but more intentional. Smaller, well-timed doses often work better than chasing fatigue throughout the day. Guarana releases caffeine more gradually, which many people find easier to time and integrate into a daily routine without sharp spikes.
