How To Choose Guarana Supplements?

The most crucial factor to consider when choosing guarana supplements is the brand reputation. This is because guarana is a unique species that only grows in the Amazonian region. Therefore, a good supplement brand would have to ethically source guarana from Brazil while maintaining the quality. 

A brand with a good track record will have well-planned protocols to harvest guarana extracts for manufacturing purposes. Brand reviews and ratings are also a good insight into the brand’s quality.  

Next, consider the guarana supplement dosage. A higher dose may bring more benefits, but it’ll also cause side effects. Therefore, opt for the lowest effective amount if it’s your first time trying out the guarana supplement. If you can tolerate low doses, slowly climb your way up to reach your optimal dosage. 

Finally, consider the cost versus supply amount. You would ideally want products that can last you 2-3 months. This will ensure a consistent supply of the product, which is also worth the money you’re paying. Choosing a guarana energy supplement can be tricky, especially when there’s a wide range of options. So take your time to make the final decision to purchase. 

Happy buying!

Frequently Asked Questions:

How much guarana is safe per day?

In general, the dose of guarana within 37-75 mg effectively improves human cognitive functions [1]. However, the optimal amount to provide an energy boost has a broader range, from 75-1000 mg daily [2]. Taking the wide range into account, it’s best to follow the doses recommended by the brand you’re using, as it’s likely to be safer and more effective. 

Do guarana supplements work?

Yes. For centuries, guarana was used by the native tribes as an energizer long before it was commercialized. This is because guarana seeds contain naturally occurring caffeine, making them an effective energizer for day-to-day use. Considering the long-standing use of guarana, it’s safe to say that guarana supplements are effective when taken as advised. 

Can you take guarana every day?

Yes, guarana is safe to consume daily in low, recommended doses. This is because caffeine content may induce dependence when taken in high amounts. That being so, do remember not to exceed the safety limits of guarana supplements. 

Do not take guarana supplements if you’re pregnant or intend to conceive. You must also consult a healthcare provider before starting guarana when taking other regular medications to ensure there are no potential serious interactions [3]

What are the negative effects of guarana?

Guarana contains caffeine and other compounds similar to caffeine, such as theophylline and theobromine [4]. As a result, guarana acts as a stimulant in the human body. Some side effects you should monitor for include: 

  • Diarrhea 
  • Nervousness 
  • Sleep disturbances
  • Stomach upset 
  • Vomiting 

In most cases, these side effects are transient. However, if they become bothersome to you, please consult your nearest healthcare provider as soon as possible.
