Taurine

Taurine

Taurine is also called an amino sulfonic acid. It occurs naturally in the human body and has many important functions. Taurine is found in large amounts in the brain, retina, heart, and blood cells called platelets. The best food sources are meat, fish, and eggs.

The body usually makes taurine on its own. But some people cannot make it and need to get taurine from their diet or supplements. Breast milk is rich in taurine, but infants who are not breastfed do not get enough taurine and do not have the ability to make it, so taurine is often added to infant formulas. It is also added to the formulas used for tube-feeding in adults.

People take taurine for congestive heart failure (CHF) and swelling (inflammation) of the liver (hepatitis). It is also used for athletic performance, boosting energy, diabetes, and other conditions, but there is no good scientific evidence to support these uses.

Despite common belief, this amino acid is not extracted from bull urine or bull semen. The name is derived from the Latin word taurus, which means ox or bull - so that may be the source of the confusion.

Sources of Taurine
The main sources of taurine are animal foods, such as meat, fish and dairy. Although some processed vegetarian foods contain added taurine, it is unlikely that these will offer sufficient quantities to optimize your levels.

Taurine is also often added to soda and energy drinks — which may provide 600–1,000 mg in a single 8-ounce (237-ml) serving. However, it is not recommended to drink soda or energy drinks in high amounts due to other ingredients that may be harmful.

Because the form of taurine used in supplements and energy drinks is usually made synthetically - not derived from animals - it is suitable for vegans.

An average diet provides about 40–400 mg of taurine per day, but studies have used 400–6,000 mg per day.

Functions in Your Body
Taurine, found in several organs, has widespread benefits. Its direct roles 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 function of your central nervous system and eyes
- Regulating immune system health and antioxidant function

Since it’s a conditionally essential amino acid, a healthy individual can produce the minimal amount required for these essential daily functions.

However, higher amounts may be required in rare cases, making taurine essential for some people — such as those with heart or kidney failure, as well as premature infants that have been fed intravenously.

When a deficiency occurs during fetal development, serious symptoms like impaired brain function and poor blood sugar control have been observed.

Taurine may improve blood sugar control and combat diabetes
Taurine may benefit people with diabetes, potentially lowering blood sugar levels and improving various risk factors for heart disease. However, further studies are needed before any claims can be made.

Some animal research suggests that an increased intake of taurine could help prevent type 2 diabetes by reducing blood sugar levels and insulin resistance.

Interestingly, people with diabetes tend to have lower levels of taurine — another indicator that it may play a role in this disease. That said, more research is needed in this area.

May Improve Heart Health
Taurine may reduce your risk of heart disease by improving several key risk factors, such as cholesterol and blood pressure.

Research shows a link between higher taurine levels and significantly lower rates of death from heart disease, as well as reduced cholesterol and blood pressure.

Taurine may help reduce high blood pressure by decreasing the resistance to blood flow in your blood vessel walls. It may also minimize nerve impulses in your brain that increase blood pressure.

In a two-week study in people with diabetes, taurine supplements significantly reduced artery stiffness - potentially making it easier for the heart to pump blood around the body.

In another study in overweight people, 3 grams of taurine per day for seven weeks reduced body weight and improved several heart disease risk factors.

Additionally, supplementing has been found to reduce inflammation and artery thickening. When combined, these effects may drastically reduce your risk of heart disease.

May Boost Exercise Performance
Taurine plays several important roles in your muscles and may aid various aspects of exercise performance by reducing fatigue, increasing fat burning and decreasing muscle damage.

In animal studies, taurine caused muscles to work harder and for longer and increased the muscles’ ability to contract and produce force. In mice, it reduced fatigue and muscle damage during a workout.

In human studies, taurine has been shown to remove waste products that lead to fatigue and cause muscle burn. It also protects muscles from cell damage and oxidative stress.

What’s more, it increases fat burning during exercise. Human studies indicate that trained athletes who supplement with taurine experience improved exercise performance. Cyclists and runners have been able to cover longer distances with less fatigue.

Another study supports this amino acid’s role in reducing muscle damage. Participants placed on a muscle-damaging weightlifting routine experienced fewer markers of damage and less muscle soreness.

In addition to these performance benefits, taurine may aid weight loss by increasing your body’s use of fat for fuel. In cyclists, supplementing with 1.66 grams of taurine increased fat burning by 16%.

Other Health Benefits
Taurine has a surprisingly wide range of potential health benefits. 

It may improve various other functions in your body, such as eyesight and hearing in certain populations. In one human study, 12% of participants supplementing with taurine completely eliminated ringing in their ears, which is associated with hearing loss.

Taurine is also present in large quantities in your eyes, with research showing that eye problems may occur when these levels start to decline. Increased concentrations are believed to optimize eyesight and eye health.

Because it helps regulate muscle contractions, taurine may reduce seizures and help treat conditions such as epilepsy.

It appears to work by binding to your brain’s GABA receptors, which play a key role in controlling and calming your central nervous system.

Finally, it can protect liver cells against free radical and toxin damage. In one study, 2 grams of taurine taken three times per day reduced markers of liver damage while decreasing oxidative stress.

Side Effects and Safety Concerns
According to the best available evidence, taurine has no negative side effects when used in the recommended amounts.

While there have been no direct issues from taurine supplements, athlete deaths in Europe have been linked to energy drinks containing taurine and caffeine. This has led several countries to ban or limit the sale of taurine. However, these deaths may have been caused by the large doses of caffeine or some other substances the athletes were taking. As with most amino-acid-based supplements, issues could potentially arise in people with kidney problems.

Vitamins and Its role on our health

Vitamins are organic compounds that people need in small quantities. Most vitamins need to come from food because the body either does not produce them or produces very little. Different vitamins play different roles in the body, and a person requires a different amount of each vitamin to stay healthy.
