Guarana vs. caffeine from coffee: Is there a difference? Another interesting property of guarana is the fact that it contributes to improving our sexual relationships.

This is due to the fact that it increases the libido since it is an aphrodisiac and invigorating element. Consequently, this means that it can increase the energy and stamina, improving the sexual activity overall, even though it will not improve the erection.

Caffeine is an allowed ergogenic support. This means that we can consume it without any issue regarding an anti-doping test.

Moreover, it has been observed that it can increase both the strength and the resistance of the muscles. This will reduce the onset of physical and mental fatigue , which is related to more intense and longer workouts or events. The main difference between a Guarana and Caffeine supplement anhydrous is that lies on the fact that the latter acts faster, apart from having a shorter effect.

On the other hand, the caffeine from Guarana will produce a progressive effect that will last a lot longer. It is important to take this into account depending on the activity that we are going to practice.

They can also be combined. These seeds are an effective way of increasing the energy progressively. This is the reason why it is perfect for those who want to improve their performance without the effects of caffeine nor energy drinks.

Pregnant women should not take supplements with high doses of stimulants. Some of the risks and side effects of guarana are the same ones that we can find in caffeine and, depending on the dose, the sensitivity, and tolerance of the person.

Pregnancy : Guarana is a plant with a high caffeine content. Generally, caffeine may raise your heart rate, blood pressure, and the amount of urine you make. Other potential effects are tremors, indigestion , light-headedness, nausea , and sleeping problems.

While pregnant , you might be more sensitive to these effects. As for the impact on the unborn fetus, there is conflicting information about caffeine's effects on miscarriages , preterm births , and low birth weights.

But adverse effects are unlikely with daily caffeine amounts of milligrams mg or less than one to two cups of coffee daily. Since additional research on guarana is needed, contact a healthcare provider to discuss the benefits and risks before using guarana during pregnancy.

Breastfeeding : Guarana is a source of caffeine. For this reason, guarana will likely have similar effects as caffeine on nursing infants. For example, 10 cups of coffee per day from a breastfeeding parent might be too much for a nursing infant.

The breastfeeding infant may experience fussiness, tremors, and sleeping problems at these high amounts of caffeine. And more than milliliters mL of coffee per day can reduce iron levels in breast milk, increasing the chances of low iron levels and anemia in nursing infants.

In general, try to limit the amount of coffee to a maximum of to mg, or five cups of coffee per day. These amounts are likely safe for babies at least 3 weeks old. But preterm and newborn infants tend to clear out caffeine slower.

Symptoms may include:. Before using guarana in animals, you can contact a veterinarian to talk about the benefits and risks. Heart conditions : High doses of guarana may be similar to caffeine overdose symptoms, such as abnormal heart rhythm and rate. Therefore, a healthcare provider may want to monitor you and make any necessary medication adjustments closely.

Liver problems : Guarana has some similar plant substances as green tea. And these substances might have a role in liver toxicity associated with green tea use. While there are no reports of liver injury with guarana, long-term guarana use at high doses isn't recommended in people with liver problems.

Seizures : Guarana may work against anti-seizure medications and increase your risk of seizures. A healthcare provider may want to monitor you closely and make any necessary medication adjustments if you have seizures. Always speak with a healthcare provider before taking a supplement to ensure that the supplement and dosage are appropriate for your individual needs.

While some studies on guarana in humans exist, more research with high-quality clinical trials is still necessary. For this reason, there are no guidelines on the appropriate dosage to use of guarana for any condition.

The specific dose may vary based on the dosage form and any medical conditions you may have. If you use guarana, follow a healthcare provider's recommendations or product label instructions. More information about the safety, toxicity, and overdose of guarana in humans is needed.

However, guarana toxicity likely resembles that of a caffeine overdose. Signs of a potential overdose include:. Per a systematic review, side effects might be less of an issue with maximum daily guarana doses of between and 1, mg. But in another review, clinical trials studied daily guarana doses of 3, mg.

If you suspect you're experiencing life-threatening side effects, seek immediate medical attention. Guarana might interact with the following medications:.

When it comes to antioxidants , guarana doesn't disappoint. The Amazonian berry offers antioxidant compounds like theobromine, tannins, saponin, catechins, and caffeine, according to Paula Doebrich, MPH, RDN , registered dietitian and founder of Happea Nutrition.

These antioxidants help the body fight off free radicals, Naidoo tells mbg, ultimately protecting cells, tissue, and organs from oxidative stress. If guarana had a claim to fame, this would be it. As Naidoo notes, "Guarana [promotes] energy due to its caffeine content, which is stimulating for both the body and mind.

As you can imagine, this can be a lifesaver when you need to shake off physical and mental tiredness. The high content of antioxidants in guarana also lends a hand to these cognitive benefits, says Naidoo.

These compounds help support brain health, which is key for optimal focus and mental clarity. According to Pasquariello, the caffeine in guarana nurtures cognitive function and performance, including important processes like memory, learning, processing, and attention.

Case in point: According to a scientific review in the journal Global Psychiatry , caffeine is considered to be a nootropic—i.

The same review found that guarana improved reaction time and accuracy of task performance in young, healthy adults, further bolstering this botanical's cognitive benefits. Moreover, in a Pharmacology Biochemistry and Behavior study, guarana was clinically shown to work synergistically 4 with Panax ginseng to promote cognitive performance.

As a source of caffeine, guarana may also help promote digestive function, notes Doebrich. What's more, the tannins in guarana may support the formation of stool by regulating water secretion 6 in your GI tract, as indicated in a scientific review in the International Journal of Molecular Sciences.

Over time, free radicals and oxidative stress can reduce skin elasticity and speed up signs of skin aging 7 , such as fine lines. However, consuming plenty of antioxidants can help protect skin tissue against these effects, especially as we get older.

As sources of antioxidants, guarana tea and supplements can aid your skin by supporting your body's natural antioxidant defenses. Additionally, a review from Skin Pharmacology and Physiology states the caffeine in guarana can enhance blood flow to the skin 8 , helping it look healthier and more youthful.

Due to the rich antioxidant content of guarana, the ingredient may have cardioprotective effects, according to a scientific review in Comprehensive Reviews in Food Science and Food Safety.

Specifically, the antioxidants in guarana have been found to protect lipid levels , which is crucial for maintaining cardiometabolic health.

Interestingly, guarana might benefit the very body part it resembles. According to a compelling study 9 in the Journal of Functional Foods , the antioxidants in guarana can help nurture eye health and vision. Needless to say, it's a guarana benefit you probably didn't see coming pun intended.

Guarana, like other sources of caffeine e. Although complications and complaints are rare, side effects are possible in some cases. For example, guarana can affect blood pressure, so it may have a negative impact if you're sensitive to caffeine or have blood pressure concerns.

Additionally, ingesting too much of the ingredient can cause jitters and contribute to caffeine crashes , while taking it too late in the day can mess with your beauty sleep. As Naidoo notes, we all react to caffeine differently, largely due to the uniqueness of our liver metabolism genetics, as well as our individualized gut microbiomes.
