Hidden dangers of energy drinks.

Energy drinks provide a quick boost of energy with ingredients designed to help mental focus and physical performance. The main ingredient is often caffeine, The Caffeine content can vary from 50 mg to 500 mg. Caffeine is a psychoactive substance, it stimulates the nervous system and reduces fatigue. It enhances dopamine signaling making it addictive. This may be one mechanism involved in Caffeine withdrawal. Caffeine intake of greater than 400 mg is regarded as unsafe. High caffeine intake can be associated with palpitations, rapid heart rate, anxiety, high blood pressure, tremors and inability to sleep or stay asleep. Caffeine also works like a diuretic often causes insensible volume losses. 

High sugar content increases thirst and a “sugar crash” later. High sugar intake is associated with inflammation. 

Herbs that are used to augment or aid performance and elevate energy levels are often heavily sprayed with pesticides. 

High concentrations of Niacin help with energy levels. Unfortunately, associated with flushing dizziness, vomiting and diarrhea. 

Taurine is often used for increasing cardiac performance. High doses are linked to abdominal discomfort, dizziness and allergic reactions. Taurine affects GABA receptors in the brain, making it addictive.

High oxalate and often high phosphorus content is associated with kidney stones. 

Bottom line:

Energy drinks have uses in certain situations but should not be used as a hydration replacement beverage. Overconsumption is easy and can lead to health implications down the line.
