Taurine is an organic compound known as an amino acid. Some believe taurine has health benefits. However, researchers need to carry out more studies to confirm these claims.
Today, manufacturers add taurine to infant formula, nutritional supplements, and energy drinks. Taurine also occurs naturally in a range of animal foods, including seafood, beef, and chicken. However, vegetarian and vegan foods tend to be deficient in taurine.
Some researchers and healthcare professionals believe that taurine may be useful in managing conditions such as epilepsy and diabetes.
Although scientists need to carry out more research, in this article, we analyze the health benefits and potential risks of taurine consumption.
Taurine is an amino acid, which is a building block of human proteins.
Researchers have
Taurine is
- regulating the volume of body cells
- stabilizing cell membranes
- adjusting the amount of calcium inside cells
- producing bile salts
The human body can produce taurine, but obtaining it from dietary sources or supplements is necessary to maintain optimum levels.
It is important to note that vegetarian and vegan foods do not contain much taurine. As a result, it may be especially important for people who follow these diets to take supplements.
Taurine plays an essential role in protecting cells from damage.
Some research suggests that taurine plays a role in brain development and the prevention of birth abnormalities. For example, when taurine levels drop, mice experience
In other rat and mouse studies, researchers have shown that when taurine loses its effect in the retina, the rodents show severe cell degeneration in that area.
Meanwhile, studies in humans have suggested that taurine may be beneficial in the following conditions:
- type 1 diabetes
- type 2 diabetes
- diabetes-induced kidney disease
- epilepsy
That said, researchers have not yet confirmed that taurine supplementation is beneficial in humans, nor have they explained how taurine affects these conditions.
In the sections below, we take a look at what the existing research suggests about taurine and its possible role in several conditions.
Scientists need to carry out further research in humans, however, before doctors can begin recommending taurine as a treatment option.
Diabetes
Several
Taurine may also have benefits for diabetic nephropathy, which is a disease of the kidneys associated with diabetes. Doctors have not yet confirmed these benefits in humans, however.
Epilepsy
A group of researchers conducted a
Taurine tends to be present in three areas of the brain:
- the hippocampus
- the cerebellum
- the hypothalamus
Scientists have also noticed disruptions in taurine balance in the brains of people with epilepsy.
Researchers tend to agree that taurine has
Studies in humans have revealed that taurine may have an antiepileptic effect, but it is not consistent. For this reason, its antiepileptic effect may not be powerful enough for health professionals to recommend taurine as a treatment option for epilepsy in humans.
The compound may have other protective effects on the brain. For example, some
Further research is required to determine the potential health benefits of taurine for people with epilepsy.
Cardiovascular disease
In Japan, doctors
Apart from producing bile salts, taurine has other actions, including:
- regulating blood pressure
- acting as an antioxidant
- acting as an anti-inflammatory agent
These actions may be involved in preventing coronary heart disease.
One of taurine’s primary functions is to combine cholesterol with bile acids and remove it from the body. When researchers gave taurine supplements to rats on a high cholesterol diet, they noticed
Taurine may also have an impact on regulating blood pressure. Some researchers suggest that taurine may block the effect of angiotensin II signaling in the kidney, which causes increases in blood pressure.
However, researchers need to conduct further studies to determine the effect of taurine on coronary heart disease risk.
Researchers tend to agree that humans tolerate taurine well.
A study that appears in the Journal of the American Pharmacists Association explored the safety of taurine in energy drinks.
Although the amounts of taurine present in these energy drinks were too low to produce any therapeutic effects, some participants reported mild diarrhea and constipation. However, the study authors point out that the sugar and caffeine content of many energy drinks can cause these side effects.
People with adrenocortical insufficiency, a condition wherein the adrenal glands produce low amounts of steroids, may experience decreased body temperature and high levels of potassium if they consume taurine.
Older studies have reported side effects in people with epilepsy who took 1.5 grams (g) of taurine per day. The side effects included:
- nausea
- dizziness
- a headache
- difficulty walking
People living with medical conditions such as adrenocortical insufficiency or epilepsy should ask their doctors if taking taurine is safe. Doctors should evaluate the safety of the product as well as the dosage.
If a person is interested in consuming taurine or taking supplements, they can speak with their health professional to find out how much taurine is safe for them.
The following
Food | Taurine content in milligrams per 100 g |
Broiled beef | 38.4 |
Broiled chicken, dark meat | 199.1 |
Broiled chicken, light meat | 14.5 |
Roasted pork loin | 56.8 |
Albacore tuna, canned | 41.5 |
Cow’s milk, 2% fat | 2.3 |
Following a strict vegetarian or vegan diet may affect the amount of taurine in the body. People who follow these diets can speak with their healthcare provider to ensure that they are getting enough taurine.
Doctors should always make parents and caregivers of children following a vegetarian or vegan diet aware of the risks of taurine deficiency.
Taurine is a compound that people obtain from their diet or by taking supplements. Many animal studies have suggested that taurine deficiency can lead to health risks.
At the moment, doctors require more evidence before they can start recommending taurine as a treatment option for conditions such as epilepsy and diabetes.
People can usually tolerate taurine at recommended doses.
