Caffeine Information
Caffeine is a natural drug that stimulates the body. It can affect the central nervous system, heart muscle and lungs. It is also a diuretic, meaning it increases urine production.
Caffeine tightens blood vessels and may worsen migraine headaches. It may also affect fertility and osteoporosis, and for some people it can irritate the bladder.
It is generally recommended that the average person should not consume more than 300mg of caffeine per day.
