Too many calories can lead to weight gain

Good thing is that Reign Energy only contains 10 calories per can, which means if you’re on a strict calorie diet, you can drink Reign as it wouldn’t mess with your calorie count.

Calories are extremely important for your body, a good amount of calories keep your heart beating at a healthy rate and your lungs breathing. But, researchers say that too many calories can be bad for you as it can lead to weight gain, and eventually obesity.

According to some research, women are advised to consume 2000 calories per day and men should consume 2500 per day. These recommended doses aren’t too less to cause your heartbeat to stop, nor too many to cause weight gain.

Caffeine In Reign Energy

Caffeine is the prime active ingredient that is included in every recipe for energy drinks, you ask why?

Well, caffeine stimulates the brain which has been studied to help ease symptoms of different neurological and psychiatric disorders. Moreover, caffeine increases alertness, attention, and energy, as well as physical performance.

So you see, there’re several alluring benefits that people enjoy, therefore, manufacturers of energy drinks add an immoderate amount of caffeine, completely ignoring the fact that too much caffeine can cause side effects like:

  • Restlessness and shakiness.
  • Insomnia.
  • Headaches.
  • Dizziness.
  • Fast heart rate.
  • Dehydration.
  • Anxiety.
  • Dependency.

Unfortunately, Reign is one of those energy drinks. Per every 16 ounces, Reign contains 300mg of caffeine which is extremely close to the recommended limit.

According to the FDA, caffeine should only be consumed in moderate amounts which are 400 mg per day for a healthy adult.

While 400 mg is the regular dose for a person who has a high tolerance to caffeine, some people are caffeine-sensitive which means 400 mg is dangerously high for them.

People with caffeine sensitivity can experience side effects when exposed to an immoderate amount of caffeine which are:

  • racing heartbeat.
  • headache.
  • jitters.
  • nervousness or anxiousness.
  • restlessness.
  • insomnia.

Moreover, as people develop a high tolerance to caffeine, they’re also developing dependency. They would crave more and more caffeine, and when they fail to satisfy those cravings, caffeine withdrawal symptoms would occur.

Have a look at the caffeine withdrawal symptoms:

  • Headaches.
  • Tiredness.
  • Difficulty concentrating.
  • Nausea.
  • Depression.
  • Muscle pain.
  • Irritability.

The only way to avoid any side effects of caffeine, you merely need to keep your energy drink consumption in moderation.

Sugar In Reign Energy

Sugar is only beneficial when it’s consumed in a moderate manner, it’s studied to provide a burst of energy that may last for a couple of hours only.

According to the AHA, women should consume 25 g of sugar per day, whereas men should consume 36 g.

Excessive consumption of sugar has been associated with side effects that include:

  • Brain fog and decreased energy.
  • Sugar Crashes.
  • Cravings and weight gain
  • Skin issues.
  • Tooth decay.
  • Higher blood pressure.
  • Inflammation.
  • Fatty liver disease.
  • Higher risk of type 2 diabetes.
  • Difficulty sleeping.
  • Heart disease and heart attacks.
  • Mood disorders.
  • Increased risk of heart attack

You can find sugar in almost every energy drink, while some may have a small dose, other will have huge contents. Nevertheless, Reign Energy is a sugar-free drink.

Energy drinks include sugar either to mask the bitterness of certain ingredients or to include another source of energy besides caffeine.

Artificial Sweeteners In Reign

Artificial sweeteners are substitutes for sugar in sugar-free energy drinks like Reign energy.

Reign Energy uses the artificial sweetener, sucralose. Sucralose is FDA approved and hasn’t been found to cause any health complications.

Moreover, sucralose doesn’t add any calories, unlike high fructose corn syrup which has been known to cause weight gain, type 2 diabetes, and heart disease.
