Caffeine: How Much is Too Much!

coffee artCaffeine: How much is too much?

I couldn’t imagine life without my daily dose of caffeine.  I often have 1-2 cups of tea in the a.m. and a latte as a pick-me-up later in the day. When I’m competing in a race or event, I always drink more coffee to get the additional boost it provides.

While everyone is different, experts suggest that 200-400 mg of caffeine (the amount in 2-4 cups of brewed coffee) a day is ok, and is linked to health benefits.

Caffeine jolts your central nervous system and metabolism, helps alleviate fatigue, increases wakefulness and improves concentration and focus. It’s also associated with reducing risk for some chronic diseases and it’s well known as a performance-enhancer among athletes.

But if you’re daily intake gets too high—more than 500 or 600 mg per day—that’s when problems may arise. Even if you’re not downing several cups of coffee or tea a day, you’d be surprised at how much caffeine is in other beverages and foods and O-T-C products like weight loss pills and some pain relievers. With potential health risks associated with high daily doses of caffeine and energy drink products specifically, the Canadian government recently set limits on energy drinks to provide no more than 180 mg caffeine per single-serve products and no more than 400 mg for larger-sized products (like a 32-ounce Monster Energy Drink).

Since the Food and Drug Administration doesn’t require manufacturers to list caffeine content on labels, it’s often hard to tell whether a product contains the stimulant, and how much.

    This is a very informative and well-written article about caffeine. I was having issues with caffeine from drinking Starbucks coffee every day for 15 years. But then I was introduced to Organo Gold Healthy Coffee and I haven’t been to a Starbucks in a year and a half. What makes Organo Gold so unique is that it’s infused with an amazing 100% certified organic ingredient called Ganoderma (it’s also known as the red reishi mushroom). Among other incredible properties, the Ganoderma has detoxifying properties so it sees caffeine as a toxin and detoxes most of it out of the body before it can be absorbed. In fact, only about 15 mg. actually get absorbed by our bodies when we drink Organo Gold Coffee. People ask me how they can get their energy level boosted, which is why they want the caffeine in the first place. The answer to that is that the Ganoderma also oxygenates the bloodstream so you get a clean, sustaining energy source which feels great throughout the day. No more jolt, jitters and crash a few hours later. And each cup contains LOTS of antioxidants and nutrients! I loved it so much when I tried it that I decided to make a business out of it!

    I think that a slightly more relevant comparison between sodas would’ve been to compare Diet Dr Pepper to regular or Diet Coke to Regular Coke & Coke Zero. Otherwise, I believe the study to be slightly flawed or possibly in some cases biased. Who’s to say that Coke is or is not higher in Caffiene than Diet Coke And I AM a Diet Coke fanatic. Or maybe comparing Dr Pepper to Coke for other comparison sake.
