Are Caffeine Tablets Safe?

Caffeine tablets are one of those supplements that gets a bad reputation. Some people are more sensitive to caffeine than others, and it can affect everyone differently. But if you’ve ever wondered whether it’s safe to take caffeine tablets or caffeine supplements, let’s see what effect they have on our bodies.

How Do Caffeine Tablets Work?

Caffeine works by mimicking a chemical called adenosine. Throughout the day, adenosine builds up in your brain and when it reaches a certain point, you get sleepy. Caffeine binds to the adenosine receptors in your brain and stops them from processing actual adenosine. As a result, you delay that sleepy feeling.

That doesn’t mean you can go on forever without sleep. Eventually, you’ll develop a resistance to caffeine. That’s why people who drink a lot of coffee, tend to really, really drink a lot of coffee, and why tapering their caffeine intake can be such a miserable experience.

How Much Caffeine Is In One Tablet?

myvitamins caffeine tablets contain 200mg of caffeine per tablet. That’s about the same as two strong espresso coffees. It’s a lot, which is why we recommend no more than 1-2 a day. The most caffeine you’ll find in a regular coffee is about 125-140 mg. Instant coffee contains about 90 mg of caffeine per serving.

How Long Do The Effects Last?

Caffeine affects everyone slightly differently, but it can stay in our body for about 5 to 6 hours. So, if you take a caffeine tablet at 9:00 AM, half of it could still be in your system at 7:00 PM. 

What Are The Benefits And Side Effects Of A Caffeine Supplement?

Caffeine can help to raise awareness, alertness, energy, and concentration but it should never be used as a replacement for rest and sleep. It should also be used responsibly as it can become addictive and dictate your sleep.
