One of caffeine’s primary actions in the human body is its stimulating effect on cognitive functions.

Each 8.4 fl oz can of Red Bull Zero contains 80 mg of caffeine. Caffeine helps to improve concentration and increase alertness.

Whether the caffeine is naturally derived or synthetic, both forms are identical in structure and effect.

Taurine is an amino acid, naturally occurring in the human body and present in the daily diet.

It is involved in a wide range of biological processes including osmoregulation, which is the regulation of the body’s cellular water and electrolytic balance.

Taurine is one of the most abundant amino acids in the brain, heart and muscles.

Vitamins are essential micronutrients that are required for maintaining normal body functions.

There are two types of vitamins: fat-soluble and water-soluble. Red Bull Zero contains water-soluble vitamins. Water-soluble vitamins do not get stored as much as fat-soluble vitamins in the body. Instead, they circulate in the blood, and whatever the body does not use is excreted. Red Bull Zero contains the water-soluble B-group vitamins niacin (vitamin B3), pantothenic acid (vitamin B5), vitamin B6 and vitamin B12.

These B-group vitamins (niacin, pantothenic acid, B6, B12) contribute to normal energy-yielding metabolism, such as the break-down of carbohydrates and proteins, and contribute to the reduction of tiredness and fatigue. Additionally, pantothenic acid (vitamin B5) contributes to normal mental performance.

Moreover, B-group vitamins play a central role in the brain. Niacin and vitamin B6 contribute to the normal function of the nervous system while vitamin B12 contributes to normal neurological functions.

Monk fruit extract: Monk fruit extract is a non-caloric sweetener derived from Siraitia grosvenorii, a fruit also called “monk fruit", which has a long history of human consumption. Monk fruit extracts are intensely sweet, and depending on their composition, range from being 100-250 times sweeter than sucrose. Monk fruit extracts are used in a wide range of products, like juices, soft drinks, candies and desserts.

Sucralose: Sucralose is a non-caloric sweetener that is made from sugar and tastes like sugar. Sucralose is produced synthetically. Sucralose is used in a wide variety of products, including beverages, baked goods, desserts, dairy products, canned fruits and syrups.

Monk fruit extract, and sucralose are among the most-tested and most-used sugar substitutes worldwide. Numerous scientific studies demonstrate that these substances are safe for use as sweetening ingredients. The safety of these sweeteners has been evaluated by regulatory bodies all over the world (e.g. FDA in the US). Authorities rely on the safety evaluations of independent scientific advisory bodies such as the European Food Safety Authority (EFSA), the United States Food and Drug Administration (FDA), and the Joint FAO/WHO Expert Committee on Food Additives (JECFA).

Water is a main ingredient of Red Bull. Dedication to its quality contributes to the iconic taste in every sip.
