Eureka Review 2019 – Pros and Cons

EurekaWhat is Eureka

Eureka is a brain supplement designed to improve memory, concentration, and focus. The formula consists of 13 natural ingredients, each having a particular set of benefits for the cognitive function. Eureka is claimed to work by facilitating the synthesis of essential neurotransmitters in the brain and therefore speeding up the neural transmission and information processing for better memory and concentration.

Eureka brain supplement is produced by Eureka Brands, LLC. Sadly we had to revise our initial review, even before publishing it on site. The reason is simple: the company no longer has an official website. The first time when we researched this brain supplement, Eureka Brands, LLC had a beautiful presentation web page, with lots of information regarding their product. But that website is just gone. We invite the company to contact us to update this section of our review.

Eureka Ingredients

Eureka includes the following active ingredients: Vitamin C 50 mg, Thiamin 18 mg, Vitamin B12 300 mcg, Riboflavin 18 mg, Zinc 18 mg, Advanced Nootropic Blend (L-Glycine, DL-Phenylalanine, L-Arginine HCI, Choline Bitartrate, Panax Ginseng Root, Ginkgo Biloba Leaf, Caffeine, L-Glutathione, and GABA) 2326,5 mg.

Other ingredients: Silica, Magnesium stearate, and Cellulose.

Benefits of Eureka

Eureka Brands, LLC claims to have developed this particular formula to meet the everyday cognitive performance needs of modern men and women. The formula is also claimed to be the result of more than five years of research in the fields of nutrients, neurobiology, and herbs, although this looks like a simple marketing message in the absence of concrete information.

The formula falls into a class of drugs known as “Nootropics,” a category of products (be they drugs, dietary supplements, nutraceutical formulations, or functional foods) which work to enhance one or more aspects of the cognitive function, such as memory, motivation, attention, focus, and concentration.

Although the advertising message often refers to the formula as a ground-breaking supplement or as a revolutionary blend, the supplement features rather common ingredients in a combination that is not necessarily unique or original.

Eureka’s ingredients list features two herbal extracts of the popular brain enhancing Ginkgo Biloba and Panax Ginseng, several amino acids such as L-Arginine, L-Glutathione, and GABA, and several minerals and vitamins. Crucial, Eureka also contains caffeine.

So let’s discuss some of these ingredients, starting with GABA (Gamma Amino Butyric Acid), which is an important brain neurotransmitter that naturally acts like a tranquilizer in the central nervous system. Laboratory synthesized GABA is most commonly used to treat a variety of anxiety disorders, sleep disorders, depression and attention deficit disorders such as ADHD. Synthetic GABA, however, does not seem to cross the blood-brain barrier effectively, making it a short-term effect rather than a long-term prerequisite for optimal brain function. Results regarding its effectiveness are therefore contradictory.


Another important ingredient here is the Ginkgo Biloba extract. Traditional Chinese medicine practitioners have been using it for a long time, particularly due to its extremely potent properties for the circulatory system and the brain. Modern research has determined that the plant may indeed help with blood thinning processes, hence improving circulation. Better oxygenation of the organs is hence promoted, making them function better.

Ginkgo Biloba is a powerful antioxidant, and it is sometimes used to fight the adverse effects of oxidative stress – one of the underlying causes of age-related brain damage. Common side effects, although rare, may include a headache, nausea, and digestive discomfort.

We welcome the addition of some amino acids in the formula. Most often, dietary supplements fail to offer the support of these essential substances. L-Glycine, for instance, is known to help regulate processes that trigger depression, ADHD, anxiety, and seizures.

How Much Does Eureka Cost?

Eureka is available in bottles of 90 capsules each, which may cover treatment for a month and a half if the suggested dose of 2 capsules per day is followed.

Eureka is not very expensive compared to other similar brain supplements. The list price for a 90 capsules bottle is $49.99, but many online retailers will sell the product as low as $39.99.

Potential Eureka Side Effects

There are no listed side effects for Eureka. However, we have to point out that the official website was not available at the moment of this review, so the only source of information was what our research team could find online.

General concerns target pregnant or nursing women, people already under treatment with prescription medication, and children under 12 years old who are advised not to use this supplement without a doctor’s clear consent.


  • The formula contains several powerful amino acids
  • Many positive reviews and testimonials online
  • Moderately priced supplement


  • Eureka contains GABA and Caffeine
  • The supplement appears unavailable at this moment
  • The official website is gone
  • The lackluster formulation in some areas

Final Verdict

Eureka Brands LLC is a small company packing a solid brain supplement. With over 130 ratings on Amazon and an overall rating of 4.1 stars, you can’t really go wrong.

In what concerns the overall formula, Eureka seems to be lacking some of the essential ingredients you can usually find in top brain supplements. Vinpocetine and Huperzine A are two common ingredients in brain supplementation, and without powerful ingredients like these, it is hard to compete with the more established names in the brain supplement industry.

On the other hand, Eureka is one of the few supplements targeting the college student market, which is surprising. We expect more products to do this in the future, but for now, Eureka is one of the very few possible options for students who seek to improve their focus, concentration, and overall cognitive abilities.

Eureka looks like a solid supplement with a good combination of all-natural ingredients. The inclusion of amino-acids is more than welcome, but the formula lacks “strong” ingredients. The ingredients in this formulations are cheap, and this is the main reason why Eureka is cheaper than other similar brain supplements.
