Caffeine increases alertness and energy, but it may have side effects when consumed in high doses. See what the experts say on the pros and cons of caffeine pills versus coffee to help you kick start your day in the healthiest way possible.

Tip

In addition to increasing alertness, coffee provides antioxidants and other nutrients that are not found in caffeine tablets. It can also be easy to ingest too much caffeine when taking pills, resulting in side effects like irritability, jitters or fast heart rate.

How Much Caffeine Is Safe?

The U.S. Food and Drug Administration (FDA) says that caffeine can be part of a healthy diet when consumed in moderation. Most consumers associate it with coffee and tea, but it is also found in chocolate and cola. Energy drinks often contain caffeine and guarana, a plant that contains caffeine.

Dietary supplements, such as No-Doz and Vivarin, are made with naturally sourced or synthetic caffeine. Commercial weight loss pills may contain this stimulant too.

But how much caffeine is safe? The FDA says that 400 milligrams per day is a safe amount for healthy adults.

For reference, coffee contains 80 to 100 milligrams in one cup, so you should drink no more than four or five cups per day. Caffeine tablets typically have about 200 milligrams in one pill, which is the equivalent of two coffee cups.

Warning

To stay safe, try not to exceed two caffeine pills per day. The caffeine content varies among brands, so make sure you read the labels to determine the exact amount and dosage.

A 12-ounce can of soda provides 30 to 40 milligrams of caffeine, while an 8-ounce cup of tea boasts 30 to 50 milligrams. Energy drinks can have up to 250 milligrams per serving (8 fluid ounces), points out the FDA.

According to the same source, children and teens should not consume caffeine. If you are pregnant, breastfeeding, trying to become pregnant or suffering from certain conditions, you may be more sensitive to its side effects. Consult a doctor to determine whether or not caffeine is safe for you.

A June 2016 study in Nutrition found that those who drank coffee had a reduced risk of Alzheimer's disease, which is the leading cause of cognitive decline. Coffee has other benefits as well, including improved memory and mental performance, states Harvard Medical School. However, more research is needed to confirm these findings.
