About Manufacturer

The official website doesn't disclose Contact Us and Our Company pages, so we couldn't find a bit of history on this one.

But, here are a few facts about this company which we extracted from their BBB's profile (Better Business Bureau):

Rejuva Brain is not accredited by the Better Business Bureau, and this company has 79 total complaints in the last three years, 53 of which were closed in the last twelve months. The complaints focused on unauthorized and unexpected charges with unresolved refund disputes. Most of the consumers' protest include signing up for what they thought was a free trial and later discovered unauthorized charges to their credit cards for additional amounts.

Moreover, BBB stated that the business is using fake celebrity endorsements in its advertising, specifically Dr. Elon Musk, Ben Carson, and Twitter. Also, this business is unable to substantiate the claims made on its official website about the efficacy and results of using the company's product "Rejuva Brain."

Rejuva Brain Ingredients Analysis

The official site did not mention nor explain their product’s ingredients openly.

The ingredients mentioned on the product package include:

  • Vitamin B12 & Folic Acid
  • L-Glutamine & Taurine
  • Acetyl L-Carnitine
  • DMAE (dimethylethanolamine bitartrate)
  • N-acetyl-L-tyrosine
  • Water Hyssop (Bacopa monnieri) leaf extract
  • Ginko Biloba leaf extract
  • Phosphatidylserine

Other ingredients are Gelatin, Rice flour, Magnesium stearate, and Silicon dioxide.

Vitamin B12 & Folic Acid

Vitamin B12 is an essential vitamin that keeps your body’s nerves and blood cells healthy.

A study published in BMC Psychiatry found that vitamin B12 levels have been linked to an increased probability of recovery from a major depressive disorder.

Progress in Neuropharmacology & Biological Psychiatry found that folic acid is also used to treat several mental health problems.


A fatty substance produced naturally in the body, Phosphatidylserine covers and protects brain cells.

While a study published in the Journal of Clinical Biochemistry and Nutrition reported that six-month supplementation of soybean-derived phosphatidylserine could improve the memory functions of the Japanese elderly with memory complaints, another study published in Mental Illness suggests that it regulates mood swings.


It's a significant ingredient of Rejuva Brain, which may improve your mental performance in stressful situations.

A study published in Frontiers Behavioral Science demonstrated that tyrosine might improve working memory during a mentally demanding task.

Another scientific review published in the Journal of Psychiatric Research concluded that supplementing with tyrosine can reverse mental decline and improve cognition in short-term, stressful, or mentally demanding situations.


It's an amino acid naturally produced by the body, which helps in providing energy.

A study published in Frontiers in Bioscience suggests that supplementation with Acetyl-L-Carnitine has shown positive health benefits in neuroinflammation, a common denominator in a host of neurodegenerative diseases.

Above scientific evidence is only for the treatment of symptoms related to some mental disorders. More evidence is needed to rate the safety level of Acetyl-L-Carnitine.


DMAE is a chemical compound that seems to affect mood, improve brain function, and enhance memory positively. But there are only a few published scientific studies on it.

A small study published in the Journal of the American Geriatrics Society done in 1977 on people who had aging-related cognitive decline reported that DMAE reduced anxiety, depression, and irritability.

DMAE was once sold as a prescription drug under the name Deanol for children with learning and behavioral problems, but in 1983 it was withdrawn from the market, thus no longer available as a prescribed drug said Healthline.


Taurine is an amino acid mainly found in the brain, spinal cord and muscle cells.

A research study conducted on the adolescent brain suggests that Taurine may have an impact on brain function.

Another research study published in Biomolecules and Therapeutics suggests that Taurine plays a role in the prevention of birth abnormalities and brain development.

Bacopa monnieri

A staple plant in traditional Ayurvedic medicine, Bacopa Monnieri may help to enhance brain function.

A two-week study published in Evidence-Based Complementary & Alternative Medicine in 60 older adults reported that taking either 300 mg or 600 mg of Bacopa monnieri extract daily can improve attention, memory, and the ability to process information by suppressing Acetylcholinesterase activity.

Gingko Biloba

A study published in Human Pyschopharmacology stated that supplementing with ginkgo may increase mental performance, but the data is inconsistent.

A comprehensive review of research found that supplementing with Ginkgo Biloba did not result in any measurable improvements in memory.

Are Rejuva Brain Ingredients Safe & Effective?

If we talk about the effectiveness of "Rejuva Brain," then the deep customer review analysis showed that the product gave positive results in some people, while most of them did not feel any differences after consumption.

Referring to BBB, this business is unable to substantiate the claims made on its official website about the efficacy and results of using "Rejuva Brain."

Also, its manufacturers choose to hide the individual dosages of each ingredient in their supplement. It means you don't know how much of each element you're getting or how effective it will be overall.

As far as ingredients' safety, their makers claim to rely on 100% pure and natural ingredients entirely but didn't disclose the list of their ingredients openly.

When we look deeper into its ingredients, their claim seems to be conflicting. We only found one plant based natural ingredients, and others are chemical compounds that may result in dangerous hazards.

As there are very thin pieces of evidence regarding its 100% effectiveness and safety, thus, you'll reach the same approach that Rejuva Brain may not provide you with an effective and safe cognitive enhancement as claimed.

The official website only mentions one side effect associated with the Rejuva Brain supplement, which is the "Stomach Upset." However, based on ingredients analysis inside the supplement, we found other possible side effects of its ingredients.

According to the National Institutes of Health (NIH), DMAE which is a major ingredient of Rejuva Brain has been associated with several potential risks such as:

And according to European Renal Association, high dose of Taurine can lead to kidney failure.

How to Take Rejuva Brain?

The official website suggests taking it two capsules once a day with a glass of water.

Does Rejuva Brain Provide 100% BrainPower?

After in-depth analysis, we have found the following reservations to give you a clear cut idea regarding Rejuva Brain effectiveness:

  • The official website didn't disclose their ingredient's list openly
  • The official website doesn't disclose Contact Us and Our Company pages, so it makes it difficult to ascertain if the company is trustworthy or to find out what actual customers have claimed
  • Rejuva Brain's maker claims to rely on 100% pure and natural ingredients entirely, but in-depth ingredient analysis showed only one plant-based ingredient
  • Referring to BBB, this business is unable to substantiate the claims made on its official website about the efficacy and results of using "Rejuva Brain"
  • Rejuva Brain manufacturers choose to hide the individual doses of each ingredient in their supplement

So, Rejuva Brain may contain some ingredients like vitamins that might be effective, but more research is necessary to claim the effectiveness of its other ingredients.

Warnings for Rejuva Brain Users

The official site didn't mention any specific signs but the ingredient's in-depth analysis results in the following serious cautions:

  • Don't take “DMAE ingredient based supplements” if you are pregnant (it can lead to neural tube defects in babies) said FASEB journal
  • Avoid it if you are on medication or with a known pre-existing medical condition because DMAE based supplements can lead to potentially dangerous drug interactions
  • Keep out of the reach of children
  • Consult your physician first before incorporating the "Rejuva Brain" supplement into your daily routine

Customers Reviews

Just started taking these, but I seem to be much more alert and clear-headed. Seem to work well. Looking forward to seeing other improvements.
I can't say if it is helping me or not. I'm still taking it regularly as directed.. I do not like it when a product that was ordered once keeps showing up in my mailbox. (Thanks for taking care of that problem.) I just received my 5th and 6th bottles of Rejuva, having just finished bottle 4. I can't really tell if it is doing any good but I keep ordering in case it is. My 82-year-old wife has Alzheimer's disease.
Jim Rogers
I have taken this product for two weeks now and I have not noticed any difference. I am disappointed and would like my money back.

Rejuva Brain Alternative – Consumers' No. 1 Choice

Overall, some ingredients in the supplement have beneficial effects such as folic acid and Vitamin B12, but the majority of the ingredients can cause potential side effects, which shouldn't be ignored.

If you visit their company profile on Better Business Bureau, you'll discover several hidden facts about them, such as 79 complaints closed in the last three years and 53 complaints closed in the last 12 months against this product.

Moreover, referring to BBB, this business is unable to substantiate the claims made on its official website about the efficacy and results of using "Rejuva Brain," and the business is using fake celebrity endorsements in its advertising, specifically Dr. Ben Carson, Elon Musk and Twitter. Due to so many concerns, this supplement might not be the best choice for you.

To maintain a good memory and brain functioning, we recommend you to try adding exercise and foods enriched in brain-boosting ingredients into your diet.

But if you still experience a lack of focus, unhealthy lifestyle, and external and internal stressors, then there are several other nootropics available in the market specifically designed to slow down the onset of age-related cognitive decline, promote long-lasting brain development, and neuroplasticity. They are powerful, 100% effective, potent, and they offer excellent value for money.

One of them we often recommend for long-term mental health that works gently and safely to promote cognitive function is Mind Lab Pro.
