According to the FDA, the caffeine limit of an adult is 400mg, so as long as you stay below the limit you should be fine.

Excessive caffeine intake can lead to negative side effects, such as:

What Are The Side Effects of Energy Drinks?

There have been numerous studies on the effects of the ingredients of energy drinks, and I’ve listed some of the more prominent side effects down below:

Though if you’re wondering if Red Bull is Bad for you, you can check this article I’ve written previously.

Caffeine Overdose

A naturally occurring stimulant, caffeine is incredibly prevalent in daily beverages; coffee, tea, and energy drinks.

As stated above, the average caffeine limit is 400mg. But this may vary depending on tolerance, body mass, and age.

Here are some symptoms of a caffeine overdose?

  • Hypertension
  • Hypotension
  • Agitation
  • Abnormal Pulse Rate
  • Abdominal Pain
  • Vomiting

Type-2 Diabetes

Energy drinks usually have high sugar content. And this may be detrimental to your health if you drink energy drinks in excess.

There is an increase of 14% whenever an adult consumes at least 1 or 2 sweetened beverages every day, and this is the case for Red Bull as well as it contains quite a far bit of sugar.


With sugar comes damage to the teeth as sugar can cause the tooth enamel, the outer coating of the tooth that’s usually hard and sturdy to corrode, which makes the teeth vulnerable to decay, causing cavities.

Energy drinks, including Red Bull, are acidic beverages, and these acids coupled with the sugar can cause significant and irreversible damage to the tooth enamel.

Frequent and excessive intake of energy drinks may cause tooth damage. So always drink in moderation and don’t forget to brush your teeth.

Affects Kidney Health

A study showed that there’s a correlation between high sugar consumption and an increased likelihood of chronic kidney disease (CKD) as sugar can increase your blood pressure and heart rate.

Looking at the amount of sugar in Red Bull, the risk of it affecting your kidney health is prevalent if you don’t moderate your consumption.

What Are The Benefits Of Red Bull?

Red Bull contains Taurine, B-Vitamins, and Inositol. These have various effects and benefits to the body when ingested or consume.

While there are infamous rumors regarding the source of Taurine, the Taurine in Red Bull is not from such a source and is safe to be consumed.

Vitamin B-Complex

There are four B-Vitamins inside Red Bull:

  • Niacin (B3)
  • D-Pantothenol (B5)
  • Pyridoxine HCL (B6)
  • Cobalamin (B12)

The four B-Vitamins found in Red Bull are water-soluble, which are a type of vitamin that’s not stored for long, where whatever that’s not used by the body would get disposed of.

These vitamins are beneficial for you as they can contribute to your overall metabolism, improve your mood, and help form red blood cells that carry oxygen throughout the body.
