    What’s Inside Rejuva Brain?

The official website did not disclose or explain the ingredients of their product.

These ingredients are listed on the product packaging:

  • Vitamin B12 and Folic Acid
  • L-Glutamine & Taurine
  • Acetyl L-Carnitine
  • DMAE (dimethylethanolamine bitartrate)
  • N-acetyl-L-tyrosine
  • Extract of water hyssop (Bacopa Monnieri) leaf
  • Ginko Biloba Leaf Extract
  • Phosphatidylserine
  • Other ingredients include Gelatin, Rice flour and Magnesium Stearate.

Vitamin B12 and Folic Acid

Vitamin B12, an essential vitamin, is vital for maintaining the health of your blood cells and nerves. BMC Psychiatry published a study that found vitamin B12 levels are linked to a higher chance of recovery from major depressive disorders. Progress in Neuropharmacology and Biological Psychiatry discovered that folic acid can also be used to treat mental health issues.


Phosphatidylserine is a fatty substance that naturally occurs in the body. It protects and covers brain cells. A study in the Journal of Clinical Biochemistry and Nutrition found that six-month supplements of soybean-derived Phosphatidylserine could enhance the memory function of Japanese seniors with memory problems. However, another study in Mental Illness suggested that it may regulate mood swings.


Rejuva Brain contains it as a key ingredient. It may help you in stressful situations. Frontiers Behavioral Science published a study that showed that tyrosine may improve working memory when performing mentally challenging tasks. A second scientific review was published in the Journal of Psychiatric Research. It concluded that supplementing with tyrosine could reverse mental decline and improve cognition when faced with stressful or mentally demanding situations.


It is an amino acid that the body naturally produces, which aids in providing energy. Frontiers in Bioscience published a study that found Acetyl-L-Carnitine supplementation has positive health effects in neuroinflammation. This is a common factor in many neurodegenerative diseases. The above scientific evidence can only be used to treat symptoms associated with certain mental disorders. To rate Acetyl-L-Carnitine’s safety, more evidence is required.


DMAE, a chemical compound, seems to positively affect mood, brain function and memory. However, there have been only a few scientific studies. In 1977, a small study on individuals with aging-related cognitive impairment found that DMAE reduces anxiety, depression and irritability. DMAE was once available under the brand Deanol, a prescription drug for children with learning and behavioral difficulties. However, it was withdrawn in 1983 by Healthline.


Taurine is an amino acids that’s mainly found in the brain and spinal cord. Taurine could have an effect on brain function, according to a research study on the brains of adolescents. A second research study, published in Biomolecules & Therapeutics, suggests that Taurine may play a role in brain development and prevention of birth abnormalities.

Bacopa Monnieri

Bacopa Monnieri, a staple in Ayurvedic medicine may be able to improve brain function. Two-week-long study in Evidence-Based Complementary & Alternative Medicine showed that 600 mg or 300 mg of Bacopa Monnieri extract can increase attention, memory, and ability to process information. It also suppressed Acetylcholinesterase activity.

Gingko Biloba

Human Pyschopharmacology published a study that found supplementing with ginkgo could increase mental performance. However, the data are inconsistent. Comprehensive research revealed that supplementing with Ginkgo Biloba didn’t result in any significant improvements in memory.

Are Rejuva Brain Ingredients Safe & Effective?

The effectiveness of “Rejuva Brain” is based on deep customer reviews. Some people experienced positive results, while others did not experience any changes after the consumption. BBB has determined that this company is unable support the claims it makes on its website regarding the efficacy of “Rejuva Brain” and the results.

It is also common for supplement manufacturers to conceal the exact dosages of each ingredient. This means that you won’t be able to know the exact amount of any element or its overall effectiveness. Their makers claimed that they rely entirely on 100% natural ingredients, but did not disclose their list of ingredients. We can see that the claims of its ingredients are contradictory when we dig deeper. Only one plant was found to be made from natural ingredients. Other chemical compounds could pose dangers. There is very little evidence to support its safety and effectiveness. Therefore, Rejuva Brain will not offer you a safe and effective cognitive enhancement.

Rejuva Brain supplement’s official website mentions only one side effect, the “Stomach Upset.” Based on the ingredients analysis of the supplement, however, we discovered other possible side effects.

  • Insomnia
  • Eye irritations severe
  • Muscle twitching
  • Convulsion
  • Redness and swelling are signs of skin irritation.
  • Drug interactions that could be dangerous

According to European Renal Association, Taurine in high amounts can cause kidney failure.
