Compare every Caffeine product across UK retailers on Suppio, ranked by true value - price per active dose, not pack size. Prices refreshed daily.
Stimulant that blocks adenosine receptors, improves focus and endurance
We rank Caffeine by price per 200mg - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
What it is
Caffeine is a stimulant, which is a substance that increases the activity of the nervous system. It works by blocking adenosine receptors, which are the parts of the brain that normally signal to the body that it is time to sleep or rest.
Why it's used
It is primarily used to improve focus and increase physical endurance. By preventing the feeling of tiredness, it allows users to stay alert for longer periods.
How it's made
Commercial caffeine is typically extracted from natural sources like coffee beans or tea leaves using solvents. It can also be produced synthetically in a laboratory to create a pure powder, which is then measured and put into capsules or tablets.
What it typically costs
Caffeine is generally mid-range in price. This is because while the raw material is widely available and cheap to source, the process of refining it into a pure, concentrated supplement adds some manufacturing cost.
