Anhydrous caffeine is simply dehydrated caffeine – anhydrous means “without water.” It is available in pill or tablet form, or as a soluble powder.
A cup of coffee may contain 40 mg to 180 mg, depending on how it is brewed.
Tea varies from 20 mg to 90 mg per 8 oz. cup.
Cola and other soft drinks contain 36 mg to 90 mg in 12 oz., and bittersweet chocolate has 25 mg of caffeine per ounce.
Suggested Use: As a dietary supplement, take a maximum of 1 serving (1 capsule) every 3 to 4 hours. Do not exceed more than 4 capsules in 24 hours.
Caffeine is a central nervous stimulant. According to the McKinley Health Center at the University of Illinois, caffeine is habit-forming, rather than addictive, and if a person who regularly drinks or eats caffeine stops suddenly, symptoms such as headache or fatigue can result.
Some people are more sensitive to caffeine, and even relatively small doses can affect them.
The International Society of Sports Nutrition states that anhydrous caffeine is more effective in enhancing performance than coffee in trained athletes who use low to moderate doses. It is beneficial for extended, exhaustive exercise and time-trial performance, and for high intensity exercise such as soccer or rugby, but not for strength-power performance such as weight lifting.
