Suffering from mental fogginess? BrainZyme promises to boost mental agility and promote clearer thinking quickly, using a range of natural ingredients. It also claims to support brain health and improve cognition and motivation with a number of vitamins, including B12, B6, and zinc. The manufacturers specialise only in nootropics for brain health and performance, citing that they are the first and leading brain supplement provider.

So, will BrainZyme improve your thinking performance?

Can BrainZyme live up to its claims of reducing mental tiredness and improving concentration? Are there are long-term health benefits from taking this supplement? The Nootropic Watchdog delves into the ingredients to find out if this nutritional supplement can deliver on its claim of being a natural brain booster with fast acting properties, and get the low down on whether it will protect your brain health over time.

What You Need To Know About BrainZyme

BrainZyme is a natural nootropic manufactured in the UK by Better Nutritional Science, containing several energy stimulating ingredients.

Suitable for vegetarians, vegans, and people who have gluten and soy allergies, it claims to be an all-round solution to those who need to think clearer, perform better, concentrate longer, and be more motivated.

Marketed at students, professionals, athletes, and parents, it claims to be more effective than coffee and green tea, another lauded miracle ingredient for its health benefits.

They have a range of sister products which they claim are more advanced for those with higher energy requirements.

What Are The Side Effects Of BrainZyme?

Whilst the manufacturers do not report any side effects and reviews do not mention much either, some of the ingredients can create unpleasant side effects. Upset stomach, headaches, and insomnia are some possible issues users may face by taking the supplement.

It is also possible that users may experience a short high energy period, but is followed by a quick crash afterwards.

How Much Does BrainZyme Cost?

The cost of BrainZyme is £9.95 for 30 capsules, with one dose being around 2-3 capsules. Value packs for 3, 5, and 10 are available. They offer free delivery on items shipped within the UK.

Our Verdict On BrainZyme

The Nootropic Watchdog are skeptical about the results of BrainZyme, and believe that any benefit in energy will be short lived and not much more than a strong cup of coffee would achieve. There may be some placebo effect as a result of taking this supplement, but it is worth a try for those with a pressing deadline or exam.

We do not believe that there will be much long-term brain health boosting benefit, due to the low quantities of active ingredients. Choline is a compelling ingredient, but medical studies are limited.

Matcha Green Tea also has some possible health benefits but needs further study to convince us. Currently, the evidence is inconclusive about the amounts needed to achieve its full potential. Overall, we do not recommend BrainZyme to our readers.

BrainZyme Review

This supplement is positioning itself as both a long-term brain health booster and a fast-acting stimulant to help get you through those pressurized situations when you need to concentrate and think clearly.

BrainZyme Facts

  • Manufactured in the UK by Better Nutrition Products as an all-natural Nootropic which is not tested on animals
  • Contains Matcha green tea which is reportedly more effective than green tea alone
  • Contains less caffeine than you might expect but contains other stimulants

However, as a nutritional supplement, there are low quantities of the active ingredients and it is therefore hard to imagine much benefit would be achieved through taking this. Vitamin B5 and B6, in particular, are rarely deficient so why they are in there at all is unknown to us.

How to Take BrainZyme

Directions for use:

  • Swallow 2-3 capsules with a large glass of water. Take on an empty stomach for best results (at least 45 minutes before food or 90 minutes after). Do not exceed 6 capsules per day. Not suitable for children under 16. Suitable for vegetarians and vegans.

As a quick energy booster to get you through an exam or other immediate deadlines, BrainZyme may provide some stimulation, but we expect the energy slump afterwards is equally as dramatic.

BrainZyme Concerns:

  • On first glance, the manufacturers appear to be adhering to the Department of Health standards and rigorously testing their products. Some of the ingredients, such as Guarana, do have studies to back up their benefits as a stimulant. However, we are dubious about their claims that this does anything for brain health overall. The inclusion of a few vitamins and minerals are at such a level as could be found in a general, all-purpose multi-vitamin.

What Does BrainZyme Claim To Do?

The manufacturers of BrainZyme, Better Nutritional Science, claim that this product is an all-natural way to boost your brain health but, more importantly, enhance cognitive performance and energy fast.

Whether you are a student studying for exams, a professional with a heavy deadline, or competing in a sport requiring mental agility, they say they can help improve your focus, the length of time you can concentrate, and boost motivation to see you through.

They say is it more effective than coffee and contains less caffeine than two-thirds of a cup of filtered coffee. Promoted as a milder version of their other nootropic supplements, it is an introduction to brain-enhancing products which are stronger and contain more ingredients.

BrainZyme states it will get to work within one hour to give fast acting benefits, but also support your long-term brain health.

Does BrainZyme Work?

Whilst some of the ingredients are known to have a stimulating effect, we believe it may be no more than the equivalent of a strong cup of coffee. It may also provide a short-lived energy increase with a particularly bumpy energy crash afterwards. The dosage of some of the ingredients is low, and therefore likely to be ineffective and some others appear to be in there for no real reason.

What Are The Ingredients of BrainZyme?

  • Matcha Green Tea Blend (350mg): Match Green Tea is considered to be a better alternative to green tea, mainly because with Matcha you ingest the whole leaf of the plant, not just the brewed water, to give you a more concentrated hit. It’s known benefits are in boosting brain function, boosts weight loss and can give your skin that healthy glow we all covet. It’s not without its downsides though and it should be consumed in moderation to avoid side effects such as insomnia, headaches, upset stomach, and irritability. Matcha Tea creates more stomach acid, which in turn can create heartburn.
  • Choline (200mg): Choline is a molecule found naturally in eggs, particularly the yolk, and is capable of enhancing cognitive function in the right quantities, by turning into acetylcholine, which is known as the learning neurotransmitter. It is recommended that users start with a low dose of 50-100mg to build up their tolerance, as if too high a dose is taken, some users may experience headaches.
  • Guarana Seed Blend (170mg): Guarana Seed Blend is what you often see in energy drinks, used as a stimulant and to promote increased energy. Also known as, Paullinia cupana, it comes from a fruit-bearing tree, the seeds of which are ground into powder and used in traditional Amazonian medicine. It does contain some caffeine, but the amount is not thought to be high, although it does contain other stimulants so should not be taken at night. It is known to interact poorly with heart medication and other health conditions.
  • Iron (4mg): Low iron levels are known to interrupt energy levels and concentration, so the addition of iron is to ensure stable levels of this important mineral.
  • Zinc (6mg): Zinc is an essential micronutrient found in meat, eggs, and legumes, and is used for maintaining a healthy immune system, hormone balance, and treating mood disorders. If deficient, it needs to be supplemented between 5-10mg daily for preventative purposes which is more than contained in BrainZyme.
  • Iodine (100µg): Iodine is thought to protect the health of the brain and is naturally found in seafood, which is not typically consumed in the quantities required in the western diet.
  • Vitamin B1 Thiamine (2mg): Vitamin B1 is usually taken for energy and stimulation but is not commonly deficient in those with a balanced diet. If someone is deficient, a supplement of around 100-300mg daily could hail some benefits but only 2mg is contained in BrainZyme.
  • B5 Pantothenic Acid (10mg)
  • Vitamin B6 pyridoxine (2.5mg): Vitamin B5 and B6 are thought to be enzymes essential for the body and have several small benefits, but there is no compelling medical evidence for why anyone would supplement them as they are generally not thought to be deficient.
  • Vitamin B12 (4µG): Vitamin B12 is believed to have benefits on neurology and brain health, but needs to be supplemented around 1mg a day to have any real benefits and the dose here is substantially lower. It is usually older people and vegans who are deficient in this vitamin.

Free from sugar, soy, GMO, salt, gluten, and gelatin.

Does BrainZyme Have Any Side Effects?

The manufacturers of BrainZyme do not list any potential side effects, but a closer look at the ingredients shows that users may experience the following issues:

  • Insomnia
  • Headache
  • Upset stomach
  • Irritability
  • Heartburn


Food supplements must not be used as a substitute for a varied and balanced diet and a healthy lifestyle. Take medical advice before consuming any food supplement, especially if you are breastfeeding, pregnant, under medical supervision or suffer from allergies. Always read the product directions before use. Discontinue use and consult a doctor if adverse reactions occur. Keep out of sight and reach of children. Do not exceed 6 capsules per day.

Are There Any Customer Reviews For BrainZyme?

The reviews on Amazon are overwhelmingly positive, causing one reviewer to doubt their authenticity, especially as they state things that seem to be more marketing gimmicks than discernible health benefits.

However, of the reviews, some users reported a ‘clean energy’ which made them less ‘jittery’ than caffeine or other products. Many reviewers bought these as a study aid and comment that they felt they were able to concentrate better and longer as a result.

Others noticed no change in their energy or state, even when taking up to four capsules.

Does BrainZyme Offer a Money-Back Guarantee?

They say they offer a 100% satisfaction guarantee, but they have conditions for returning the product. It must be within 30 days of receipt of your shipment, returned in the original condition, unused or no more than 6 capsules used and in the original packaging. It will then be inspected before a decision about a refund will be made.

This does not imply a 100% satisfaction guarantee, given 6 capsules might only be one day’s worth of the supplement and not enough to make a judgment.

Where Can I Buy BrainZyme?

BrainZyme is available from their own website, as well as third-party retailers such as Amazon.

  1. Hi,
    I have started using BZ. I had a cortisone injection in my neck that causes a massive Embolic Stroke.

    I suffer from memory loss; my master’s degree is now just a pretty piece of paper.

    I took the reviews on BZ on face value; then I researched it online. I even emailed the support team and received no response, other than a standard reply from Robert.

    Having now taken it, I can safely say that it is not as stated. Day 1, no effect not even as if I had a coffee. Just an awful dry mouth, and a gurgling stomach, and I have just completed 22 hours intermittent fasting. So as required, taken it on an empty stomach. With lots of water.

    I suffer dreadfully with post-stroke fatigue, and just hoped that it would assist in some small way.

    Two tablets and no effects snake oil perhaps? I will wait and see if there are any beneficial aspects and return with more detail.

    All it is doing is leaving me feeling the same, other than a run to the toilet, which I won’t go into within 30 minutes of taking it. Correction while writing a second run to the toilet within 45 minutes.

    Please do not waste your money.

    BrainZyme have my email address, and I am happy to speak to you directly.

    I will take this until the packet runs out, then I’ll do a fully documented review. Amazon will probably prevent a truthful review going on as it damages their reputation as a reputable firm.
