How much is too much?

According to the U.S. Food and Drug Administration, 400 mg of caffeine a day is not considered to have adverse effects in most adults, although some people might be more sensitive to caffeine than others.

There are several sources of caffeine:

• Energy drinks

• Coffee

• Tea

• Soda

• Pre-workout supplements

• Chocolate

• Certain medications

• Other caffeinated beverages

For instance, a 300 mg energy drink along with coffee can easily exceed the total caffeine intake level of 400 mg.

Individuals with certain health conditions or medications, children and teens under 18, and pregnant and breastfeeding women may require other limits. When applicable, the FDA advises speaking with a healthcare provider about the use of caffeine.

An adolescent's perspective on energy drinks.

Final Verdict

The most effective energy drink for 2026 will depend on the type of drink you're searching for.

Bloom offers a wellness alternative with 180 mg natural caffeine in its standard, larger can.
