Caffeine Content In Irn Bru Energy

Irn Bru Energy has 120mg caffeine in a single can.

Irn Bru Energy has a moderate amount of caffeine as compared to drinks like Bang Shot.

It’s not too much to the point where you can’t handle it due to your low caffeine tolerance, but it’s also not so little that you won’t get your desired result.

I personally like to have 50mg to 100mg of caffeine in a single day, so 120mg might be a little too much for me. However, how much caffeine do you have in a day totally depends on your caffeine metabolism.

When consumed in moderation, caffeine does have some health advantages:

  • Increased Physical Performance
  • Reduced Fatigue
  • Increased Alertness
  • Boosted Focus
  • Improved Brain Function
  • Improved Decision Making

However, to get these benefits it’s important to have caffeine under recommended intake.

According to the FDA, an adult shouldn’t have more than 400mg of caffeine in a single day.

Consuming more than that can cause some serious health issues, such as:

  • Anxieity
  • Increased Blood Pressure

  • Dizziness
  • Headache

  • Immediate Burst of Energy
  • Stored Energy
  • Instant Mood Boost
  • Improved Thinking Skills

Still, you should consume sugar to a certain limit, given that recommended sugar intake should be below 30g in a single still. This much sugar content of Irn Bru Energy is more than this.

Consuming an excessive amount of sugar can cause the following health issues:

  • Weight Gain
  • Diabetes
  • Depression
  • Fatigue
  • Acne
  • Skin ageing
  • Tooth decay
  • Increased Risks of Heart Disease
  • Increased Risks of Cancer

Is Artificial Sweetener In Irn Bru Energy Gluten Free?

Besides regular sugar, Irn Bru Energy has 2 artificial sweeteners: Aspartame and Ace-K.

Both of these artificial sweeteners are gluten-free sweeteners and are low-calorie. It’s also safe to consume since it’s approved by FDA.

Artificial sweeteners can be better than regular sugar since they won’t increase your blood sugar levels increase your calorie intake.

However, you should still have it in limited quantity to avoid any possible side effects caused by excessive consumption of artificial sweeteners.

Calories In Irn Bru Energy

A single can of Irn Bru Energy has 153 calories.

For context, a woman should consume up to 2000 calories in a day and a man should consume up to 2500 calories in a day.
