Some experts say that caffeine is the world’s best “drug.” In its natural form – meaning the way it’s naturally found in coffee and tea, versus being injected artificially into something like soda – it can work alongside antioxidants to provide major health benefits. For example:

  • Caffeine is a proven brain booster! Studies show the natural compounds activate the areas of the brain responsible for alertness, and cognitive thinking skills. And drinking 3 cups of coffee a day can reduce your odds of developing dementia by 65 percent.

  • The caffeine in coffee and tea can also increase your lifespan. That’s because when it works in conjunction with the antioxidants, it can strengthen your body’s defenses against disease. Researchers say that caffeine can slash your odds of developing diabetes in half. And your risk of certain forms of breast cancer by nearly 60 percent.

  • It can even make you thinner! Research shows that caffeine boosts your metabolism and your body’s ability to burn fat.

But there’s a downside. The more caffeine you drink, the higher your tolerance, which means you progressively need more. So, if you’ve been guzzling coffee for years and feel like it’s stopped working its magic, here are healthy ways to get your caffeine kick back:

  • Go caffeine-free for a week. Do this first. Experts say it’s like pushing your body’s reset button. Your liver enzymes will return to normal, and your brain adjusts. So, when you start drinking caffeine again, you’ll need much less to get a jolt.

  • Put your caffeine consumption on a schedule. This will help you maintain a constant level of caffeine in your bloodstream. For help, try the free smartphone app, Caffeine Zone 2. You enter in stats like your weight, coffee habits, and bedtime, and the app instantly calculates the perfect amount of caffeine and when to consume it.
