Benefits of energy drinks can include higher energy spikes and a reduction in fatigue. A 2020 study states that pre-workout and caffeine supplements result in higher energy expenditure, more feelings of alertness and focus, less fatigue, and improved cognition.

However, people drinking or considering consuming energy drinks should be aware of the risks. In particular, many energy drinks have sugar, usually in high amounts, that can contribute to diabetes, insulin resistance, and obesity. A 2017 study warns that this is a serious problem, particularly when people consume them regularly.

However, sugar-free energy drinks are not without risks. Some have ingredients that can still spike blood sugar while consuming too much can lead to heart problems, anxiety, and other health risks.

Here are the answers to some common questions about these drinks.

However, people should ensure they drink enough liquid, such as water, during and after workouts to prevent dehydration.

Can I have too much energy drink?

Yes. According to the National Center for Complementary and Integrative Health, consuming too many energy drinks can have serious side effects.

Side effects include dangerous changes in blood pressure, dehydration, anxiety, and heart and blood vessel conditions.

Drinks with sugar or ingredients that increase insulin resistance also increase the risk of diabetes and obesity.

What to do if energy drinks make me jittery?

Jitters are a sign of consuming too much caffeine. A 2018 study reports that jitteriness is more common in people who consume energy drinks than those who drink coffee.

People getting jitters should stop drinking energy drinks and contact a healthcare professional if the jitters who do not stop.
