The best focus drinks in the UK, compared

What is the best focus drink in the UK?

The short answer

It depends what you want from the can. For a stated mushroom dose without caffeine, Grass & Co. FOCUS has 1,000mg of Lion's Mane extract per 250ml can and Vitamin B12, which contributes to normal psychological function; it is in the Sainsbury's meal deal nationwide, Ocado, Booths, WHSmith and Holland & Barrett. For a caffeine hit, Neutonic has 120mg per can but no mushrooms and artificial sweeteners. For the least sugar, TRIP (1 to 2g) and Water Junkie Wide Awake (1.8g) beat us, though Water Junkie does not say how much Lion's Mane is in the can.
