Look friend, the industry won't reveal for anycost about their all ingredients or which are haram. But here are some ingredients which they shared-- Basically, Red Bull is a mix of sugar, caffeine, taurine and several B vitamins, all of which are well known for their energy-promoting qualities. Take a closer look at the powerful drink’s active ingredients: Glucose & Sucrose: Red Bull has 27 grams of sugar per can, which is actually a little less than most soft drinks but still a massive amount of the sweet stuff. Sugarfree Red Bull contains the artificial sweeteners aspartame, acesulfame K and sucrolose instead of sugar, which have recently been linked to a massive increase in cardiovascular disease. Caffeine: Red Bull contains 80mg of caffeine, about half of other soft drinks and about the same as a cup of coffee. Caffeine’s stimulating mental and physical benefits have been well documented, with some even arguing that coffee’s introduction to the Western World made possible the Industrial Revolution. Caffeine works by blocking adenosine, a sleep-promoting brain chemical, which in turn makes your body release adrenaline. Caffeine is the world’s most widely used psychoactive substance, and over-consumption can cause diarrhea, twitching, racing heartbeat and nervousness – otherwise known as the “caffeine jitters.” Taurine: Taurine, or 2-aminoethanesulfonic acid, is an amino acid naturally made in the human body. Found in the lower intestine and a major component of bile, taurine is an antioxidant that helps to move minerals throughout the system and generate nerve impulses. Each can of Red Bull contains 1000mg taurine, and although Red Bull containing the substance was banned in France for awhile, at this point all bans are off and taurine is generally considered safe. Glucuronolactone: This naturally occurring chemical is found in connective tissues and plant gums. A carbohydrate,glucuronolactone is a stimulant with mild anti-depressant effects that helps improve memory and concentration. It also has detoxifying qualities and can help remove waste from the body. Inositol: Inositol is a mood-booster that helps the brain use serotonin, and can be found in many foods such as oranges, cantaloupes and high-fiber nuts and beans. Niacin: B vitamin that helps with energy formation and use. D-Pantothenol: Also known as vitamin B-5 or Pantothenic Acid, D-Pantothenol is an essential nutrient that improves mood, boosts metabolism and helps to turn fat into energy. Vitamin B-5 deficiency has been connected to a host of mental and physical health problems including acne, fatigue, muscle cramps and apathy. Pyridoxine HCL: Otherwise known as vitamin B6, pyridoxine HCL helps the body to form red blood cells and use oxygen, improving mood and energy levels. Vitamin B-12: Like vitamin B-6, vitamin B-12 helps form red blood cells for oxygen utilization.
