![Is Taurine a Stimulant or Depressant](https://images.medicinenet.com/images/article/main_image/what-is-taurine-and-what-does-it-do-to-the-body.jpg?output-quality=75)
Taurine is an amino acid that is found in many energy drinks due to its stimulating effects. However, it is actually a nervous system depressant that just has stimulant-like effects.
Taurine is a strong activator of GABA receptors in the thalamic region of the brain. Activated GABA receptors release inhibitory GABA neurotransmitters. These neurotransmitters cause more sedation than stimulation in the brain.
What does taurine do in the body?
Taurine is naturally present in the brain, eyes, heart, and muscles. Important functions of taurine include:
- Maintaining proper hydration and electrolyte balance in your cells
- Forming bile salts, which play an important role in digestion
- Regulating minerals such as calcium within your cells
- Supporting the general central nervous system function and eye function
- Regulating immune system health and antioxidant function
Taurine deficiency is very unlikely, as it is available in many foods and naturally produced by the body.
What are good sources of taurine?
Foods naturally high in taurine include animal products such as seafood, meat, and dairy.
Plants do not contain a significant amount of taurine. Therefore, people who follow a vegetarian or vegan diet are more likely to have lower levels of taurine.
Taurine deficiency is unlikely, however, due to the body's ability to produce taurine in the liver using various amino acids.
A typical American diet contains 123-178 mg of taurine a day, and a lacto-ovo-vegetarian diet that includes dairy products and eggs contains about 17 mg of taurine a day.
Taurine is also found in energy drinks, which usually contain approximately 750 mg per 8-ounce (237 mL) serving. The type of taurine used in energy drinks and supplements is artificial and not derived from animals, making them suitable for people who follow a vegan or vegetarian diet.
What can cause taurine deficiency?
Taurine is required by the body to perform essential body functions. Your body may require higher amounts during times of illness or stress. Situations that can lead to taurine deficiency include:
- Kidney or heart failure
- Premature infants who are fed intravenously
These people may have to obtain taurine through supplements or food sources.
What happens if you are deficient in taurine?
In animal studies, taurine deficiency has been found to cause the following:
- Eye damage
- Chronic liver diseases
- Muscle weakening
- Increased risk of type II diabetes
Taurine deficiency is rare, however, and the effects are not fully understood.
