Caffeine is a stimulant, often found in tea or coffee that can make you feel more alert and awake. It is extremely popular in the UK, as people drink on average around 123 million cups of tea per day and 90 million cups of coffee!

 However, caffeine, when taken by itself, at higher amounts can lead to side effects such as jitters, anxiety, mood swings or a crash, which get worse over time. These side effects then reduce the ability to think clearer and get more done.

The good news is that when caffeine is mixed with L-theanine (a naturally occurring protein extract from tea leaves) at a ratio of 1:2, it allows for even better effects than taking caffeine alone, with many users experiencing smooth energy and focus uplifts with no side effects.

Brainzyme Focus Original™ is a brain food supplement, containing both caffeine (in the form of Guarana) and L-theanine at the correct 1:2 ratio and can provide a focus, concentration and energy boost that lasts up to 6 hours per serving of 2 capsules, with no side effects.

Additionally it contains powerful B-vitamins for energy, a generous amount of Choline (found in broccoli) to reduce headaches and improve functioning, and essential minerals for brain health.

Brainzyme Focus Original™ works quickly with its powerful nutrient formula, combining FOUR different supplements into ONE - including Theanine, Choline, Guarana, Vitamins and Minerals. It provides a fast, easy and healthy way to get the caffeine boost you require with no side effects.

It’s the perfect Caffeine & Theanine supplement!
