However, even if high caffeine is often linked with better physical performance and mental energy, it can sometimes cause caffeine crashes. 

Overconsumption of this stimulant can lead to :

  • Nausea
  • Headaches

Therefore, it is best to only consume one can of Reign energy drink per day to avoid these symptoms.

  • Enhance mental focus and alertness
  • Help with Weight loss
  • Good short term recall

Does Reign Have Sugar?

Reign is a sugar-free energy drink. However, it does contain artificial sweeteners.

Although the drink is labeled as a sugar-free drink, it still packs plenty of sweetness. The sweetness comes from acesulfame potassium and sucralose

Sucralose is 320 to 1,000 times sweeter than sugar and is probably alright to use in moderation. However, using artificial sweeteners may affect your gut health.

Reign probably won’t impact your weight loss diet because it does not contain sugar. However, you still have to take it in moderation because overdoes of sucralose can cause:

  • Increased blood sugar
  • Increased insulin levels
  • Reduced bacterial gut health

All in all, sucralose will not cause any sugar crashes. But still, it’s better to take only one can of Reign because of the high caffeine content.

Acesulfame potassium is also another good alternative to sugar. It is calorie-free and 200 times sweeter than regular sugar.

It is healthy to consume acesulfame potassium or ace-k. However, long time exposure to it can cause potential health issues such as:

  • Headache
  • Depression
  • Nausea
  • Liver Effects
  • Kidney Effects
  • Visual Disturbances

Are Reign energy drinks bad for your heart?

Overconsumption of Reign energy drinks can be harmful to your heart health. 

Just like other energy drinks, Reign has the potential to obstruct the blood flow in your arteries due to its high amount of caffeine. 

We need more studies to drive a firm conclusion about the Reign energy drink effect on the heart. However, I will recommend that is probably best to limit your consumption to only one can per day. 

Is Reign bad for Your Liver?

Reign energy drinks can be bad for your liver or gut system. 

Not only Reign but any other energy drink can pose a danger to the liver and cause acute injury. The study here shows that overconsumption is linked to acute liver injury and that it can occur abruptly depending upon extremities. 

It’s better to consult your doctor before consuming energy drinks if you have any liver problems,.

Final Verdict

While Reign is considered a healthy drink due to zero calories and zero sugar, it is still not an ideal drink for everyone because of the high amounts of caffeine in one can. 

I would recommend you only consume one can of Reign a day as two cans will exceed the recommended limit and might cause side effects like headaches and jitters.

Although Reign, just like any other caffeinated beverage, can be a good source of energy, too much of it can still be detrimental to a person’s health.

You should follow a healthy diet and an active lifestyle if you want to remain healthy instead of relying on energy drinks or any other artificial drink for that matter. Lastly, it is best to limit your caffeine intake to avoid caffeine’s potential side effects.
