UK Doctor, Dr Sarah Nicholls

“Brainzyme® [FOCUS™] contains matcha, guarana and choline, which are all well known to boost cognitive effects”

Dr Sarah Nicholls, a UK doctor reviews Brainzyme® FOCUS™

“Brainzyme® [FOCUS™] is a nutritional supplement, which means that it’s a food supplement, rather than being a medicine. It has a variety of vitamins, minerals and other nutrients that are intended to boost concentration, help you be more motivated, give you more energy and boost your memory.

It contains Matcha green tea powder, Guarana and Choline, which are all well known to boost these cognitive effects. And it’s not like energy drinks and coffee, in that you won’t experience palpitations or restlessness you might experience with highly caffeinated drinks, and you should also not experience the typical crash you might do after coffee. They have a few different varieties, my favourite is the [Brainzyme® FOCUS] ELITE™."

Psychologist & counsellor, Tim Grivell

“I found it much easier to stay on task and felt like more got done.”

Tim Grivell, registered psychologist & counsellor reviews Brainzyme® FOCUS™

“My favourite natural substitute is a supplement called Brainzyme® [FOCUS™], which is fairly new, and I was initially pretty sceptical about, but actually in my experience, it does seem to compare very favourably. I certainly felt I could switch tasks as needed a lot better…

If you do choose to go down the natural route, my particular favourite is the Brainzyme® Professional [Brainzyme® FOCUS PRO™], which is their ‘mid-range’ option.”

Helen Villiers, BACP registered psychotherapist reviews Brainzyme® FOCUS™

“I’m a psychotherapist and I’ve got ADHD. I really struggle to focus. I’m writing a book at the moment and focus is really important to write a book, because y’know, you need to focus to write!

I’ve been taking Brainzyme® FOCUS PRO™ and they have changed everything for me. They’re all natural, it’s scientifically proven to help, and it’s just personally proven to help.

I love them. I cannot recommend them highly enough if you are struggling with ADHD, focus or brain fog. My favourite is Brainzyme® FOCUS PRO™ but there’s loads of others that you could check out too!”

The Times

Peta Bee tries Brainzyme® FOCUS™ and is convinced “nootropics are worth pursuing”

The Times features Brainzyme®

“The most noticeable effect, even on the first day of taking them, was the alleviation of my mid-afternoon slump…

If I popped my nootropic at noon, I felt less inclined to drop off at my keyboard at about 3pm... [Brainzyme® FOCUS™] did convince me that nootropics are something worth pursuing.”

- Peta Bee, writing for The Times.

Edinburgh Evening News

“So as I start the lengthy wait for the answer to my personal ADHD question, I'm coping by boosting my brain with a Brainzyme supplement called Focus”

The Edinburgh Evening News features Brainzyme®

"l turned my attention (or lack of it) to, an Edinburgh company making supplements that many ADHD brains find helpful.

I was attracted to their use of natural ingredients in formulations designed to help brain and immune system function, and so decided l'd give it a go.

So as I start the lengthy wait for the answer to my personal ADHD question, I'm coping by boosting my brain with a Brainzyme supplement called Focus to give me some much needed plant-powered concentration and better mental performance, and l feel so much better for it. My son has also tried the supplements and after some positive feedback from those around him, I’m hopeful that we can stay on the natural path."

- Hayley Matthews, writing for the Edinburgh Evening News.

Daily Mail

“Brain-fog busters in a bottle”

Daily Mail reviews Brainzyme® FOCUS PRO™

“This is a superb combination of antioxidants, phytonutrients, B vitamins, minerals plus amino acids L-theanine and L-tyrosine.”

“L-tyrosine is used to synthesise chemical messengers and helps to improve memory during stressful situations, such as multitasking. In addition, it supports immune function and energy production”, stated Sian Baker (Registered Nutritional Therapist).

This is a 100 percent plant-powered ‘nootropic’, or smart drug. Nootropics are the brain boosters of the moment, even though natural ones, including ginkgo biloba, have been used for centuries in Chinese medicine and ayurvedic healing.

MY VERDICT: [My husband told me] I should take it more often. ‘You lit up. You were very different. You had more words, you were more upright.’

Rating: 4/5

Nutraceutical Business Review

“An effective alternative to drugs that enhance mental performance”

Nutraceutical Business Review features Brainzyme®

 “Smart drugs are increasingly common. Everyday pressures on students, professionals, athletes and active people who need high levels of concentration means that many turn to smart drugs: pharmaceuticals used off-label to try to increase brain-power.

But, what if there was a way to achieve similar things through more natural means, such as food supplement ingredients or vitamins? Could putting your brain on food with a nutritional smart drug work as well as — or better than — a pharmaceutical smart drug?

Brainzyme [FOCUS™], a food supplement pioneering in the field of nutritional cognitive enhancement, answers this question with a resounding ‘yes!’”.

Trail Running Magazine

Brainzyme says its capsules are fast-acting and take effect within the hour.”

Obstacle Race Magazine

“Taking these is a little like having the power to flick a switch in your brain to have it working at full capacity all the time and without any crash”

Obstacle Race features Brainzyme®

“Another way to get a head start is to use supplements called Nootropics. These food supplements are designed to help you think clearer, concentrate longer and just generally get the most out of your brain. Taking these is a little like having the power to flick a switch in your brain to have it working at full capacity all the time and without any crash.

Brainzyme have hit the UK market with a nootropic which is really making waves in the sporting and professional circles. A healthy list of athletes [including] Britain’s best Badminton player Kirsty Gilmour are already raving about the benefits of these brain boosting supplements.

British Indoor 800m Champion, Guy Learmonth

“Improved my mental performance, concentration and alertness in training”

Guy Learmonth, British Indoor 800m Champion reviews Brainzyme® FOCUS™

“Being an athlete, I'm naturally a bit sceptical with all supplements that I put into my body but with Brainzyme® [FOCUS™] I've found it to be an incredible food supplement for training, racing and all aspects of my life away from the track. Races at the highest of levels come down to fine margins, winning or losing, medaling or not, can come down to hundredths of seconds and Brainzyme® [FOCUS™] is helping provide me with that natural cognitive enhancer to gain that mental edge over my rivals.

The power of the mind is widely overlooked when performing, but I truly believe winning and losing is determined weeks before anyone steps out onto the track and that is why I am bringing Brainzyme® [FOCUS™] into my everyday life, to improve my mental performance, concentration and alertness in training on a daily basis so that come race day, I am 100% mentally as well as physically ready."

- Guy Learmonth
