What to Look For in a Caffeine Pill

  • Caffeine content - The average healthy adult will want anywhere from 100 to 200 mg of caffeine in their caffeine pill. Too much caffeine may lead to jitters and trouble getting to sleep. Any less is not likely to produce the type of jolt you’re after. (1)
  • Value/price - With a cup of coffee at Starbucks costing upwards of $5, caffeine pills are a far better value proposition. Of course, with caffeine pills, you don't get to enjoy the bland corporate furniture and soulless atmosphere of SBs, but you do get the pick me up you need. And over the course of a week, you'll save enough for a nice dinner.
  • Other ingredients - You buy caffeine tablets for caffeine, not vitamin C. Some manufacturers though pad their caffeine pills with fillers to make them appeal to a wider audience. Whether you appreciate a lot of extras in your caffeine pills is up to you.

Caffeine Pills vs. Coffee

  • With a cup of coffee or espresso, it can be darn near impossible to determine just what kind of caffeine jolt you're getting until your pupils are pegged, and you're ready to climb a rock wall using only your fingernails. With caffeine pills, you know exactly how much caffeine you're getting.
  • Many people do not like the taste of coffee no matter how you dress it up and so they don’t get to enjoy caffeine’s many health benefits. Caffeine supplements alleviate this problem and allow those not enamored of coffee to still enjoy a caffeine boost.
  • Often times getting a cup of coffee when you hit the afternoon energy wall can be nearly impossible. With caffeine pills, however, you simply take one and get back to work without skipping a beat.
  • Even if you can drum up a cup of coffee in the afternoon, chances are it will only provide a fraction of the energy boost you’ll get from caffeine pills. And it will take longer to kick in.
  • Regular coffee drinkers also tend to suffer from yellow teeth. There is no such embarrassing development with caffeine pills. (2)

Benefits of Caffeine Tablets

  • Sharper mental focus - There’s little doubt that as the caffeine from your caffeine pill begins to increase your metabolism more blood will be pumping through your veins into your brain where it will deliver more oxygen and provide a higher level of mental alertness, focus, and awareness.
  • Enhanced athletic and physical performance - Few are the people who workout without first either drinking a strong cup of coffee or taking caffeine pills. The boost you get from a caffeine pill can make the difference between achieving your physical performance goals and coming up short. (3)
