Caffeine
is a bitter substance found in coffee, tea, soft drinks, chocolate,
some nuts and certain medicines. It has many effects on the body's
metabolism, including stimulating the central nervous system. This can
make you more alert and give you a boost of energy.
For most people, the amount of caffeine in two to four
cups of
coffee a day is not harmful. However, too much caffeine can make you
restless, anxious and irritable. It may also keep you from sleeping
well and cause headaches, abnormal heart rhythms or other problems. If
you stop using caffeine, you could get withdrawal symptoms.
Some people are more sensitive to the effects of
caffeine than
others. They should limit their use of caffeine. So should pregnant and
nursing women. Certain drugs and supplements may interact with
caffeine. If you have questions about whether caffeine is safe for you,
talk with your health care provider.
Other than coffee which contains a certain amount of
acid, an
alternative way to increase caffeine in your system is by taking
caffeine pills. Effective doses are 200 mg and up every 4 hours. Some
people take more. Caffeine tablets increase a persons alertness because
they are a physo active stimulant to the brain.
Use Caffeine Pills and Tablets for late night studying,
long drives
and for times that lack of sleep cannot be avoided. Use caution when
taking these supplements and do not overdose. Use them for only the
minimum time necessary to produce t he desired results.
