What Is Taurine? How Does It Work?
Taurine is an amino acid found throughout your body. It is crucial in most metabolic processes. And unlike most amino acids, taurine is not used to build proteins. It has an entirely different role to play. What Are Its Benefits? It helps regulate blood pressure, boosts metabolism, and improves heart function and blood fat levels. Who Can Use It? Anyone can take taurine except people who are pregnant or nursing. How Often? You can safely consume taurine every day according to the recommended dosage. Caution Taurine can aggravate bipolar disorder and increase lithium levels in the body. Consult your healthcare provider before taking supplements.
Your body can produce some amount of taurine, which is why it is also called a ‘conditional’ amino acid. You can get some of it naturally through food. Even taking supplements can help. Taurine’s main functions happen in the central nervous system. It aids in its development and offers cytoprotection (where chemical compounds protect cells from harmful compounds). Taurine deficiency can lead to cardiomyopathyi A heart muscle disorder that makes it difficult for the heart to pump blood to the rest of the body. It can lead to heart failure. , renal dysfunction, severe damage to retinal nerves, and even developmental issues (2). Taurine is also significant for cell development and survival, and it is one of the most abundant substances in the ocular tissues. Taurine also works as an antioxidant, fighting oxidative stress and cellular aging, which may help improve skin health. Lucas, a YouTuber, shared his personal experience after taking taurine. He said, “Just based on personal experience I know that I subjectively noticed a reduction in internal chatter racing thoughts and general social anxiety when I’m like meeting new people or at a party when I take taurine (i).” All of this only makes us wonder about taurine’s powerful benefits. Let’s see how it can help you live a better life – in detail.
What Are The Benefits Of Taurine?
1. Taurine Can Help Fight Obesity
Taurine has a role to play in fat absorption and breakdown. A study done on 30 college students showed how taurine supplementation reduced triglycerides and the atherogenic index (ratio of triglycerides to HDL cholesterol) significantly (3). The study concluded by stating that taurine could positively affect the metabolism of fats and even cut the risk of heart disease in obese individuals. Taurine levels in tissues were also found to be depleted during obesity in humans. This might establish a relationship between taurine deficiency and obesity (4).
2. Promotes Heart Health
A Japanese study shows the link between increased taurine intake and reduced risk of heart disease (5). Taurine also helps lower levels of blood cholesterol and blood pressure. Supplementing this amino acid was also found to reduce arterial thickening, which can cause heart attacks. This way, it also reduces hypertension – a major cause of heart failure. In yet another study, taurine supplementation had reduced homocysteine levels. As high homocysteine levels are associated with heart disease, taurine can work wonders in this aspect (6).
3. Aids Diabetes Treatment
Long-term taurine supplementation was found to lower blood sugar levels in diabetic rats. And interestingly, this happened without any dietary changes (7). Treating with taurine also prevented diabetes onset as it had suppressed the impending hyperglycemia (8). And as per reports by the American Diabetes Association, diabetes is characterized by taurine deficiency. This deficiency is also linked to diabetic retinopathyi High blood sugar levels damage blood vessels in the retina and the tissue in the back of the eye, which results in this disorder. , neuropathy, and nephropathyi A term used to indicate damage to blood vessel clusters in the kidneys that filter waste from the blood, which can lead to kidney failure. (9).
4. Fights Stress And Boosts Brain Health
A Chinese study shows how taurine can exhibit anti-depressive effects and improve the symptoms of depression. It can also contribute to brain function and development and help improve memory and cognition. (10). Taurine was also found to activate the GABA receptors in the brain – these receptors interact with some key neurotransmittersi Chemical messengers responsible for transporting chemical signals from one nerve cell to the subsequent target cell. that promote brain development (11).
5. Promotes Liver health
Studies show that taurine can reverse liver injury caused by excessive alcohol consumption. In tests conducted on rats, those ingested with taurine showed reduced rates of fatty degradation and inflammation (12). Dietary supplementation of taurine also reduced liver injury in patients with chronic hepatitis (13). Taurine also protects your liver from oxidative stress and free radical damage. In a study, 2 grams of taurine taken thrice a day had reduced liver damage due to oxidative stress (14).
6. Taurine Enhances Vision
The fact that taurine is the most abundant amino acid in the retina explains a lot. Taurine has powerful antioxidant properties that can help boost retinal health and prevent vision ailments (15). Taurine depletion has also been associated with damage of the retinal cones and retinal ganglion cells. The amino acid can also prevent cataracts and dry eyes – which makes it an important nutrient for eye health (16).
7. Boosts Exercise Performance
Studies show how taurine enhances exercise performance. The amino acid also helps reduce exercise-induced muscle fatigue (17). In rats ingested with taurine, the duration of running time to exhaustion had significantly gone up – which means that taurine may help one perform physical activity for longer periods without getting exhausted.
8. Combats Inflammation
The primary role of taurine in the human system is as an antioxidant – which is one reason it helps fight inflammation in the body. Studies also promote the use of taurine in drugs to fight chronic inflammatory diseases (18). Taurine also aids the treatment of periodontitis, which is the inflammation of tissues around the teeth (19).
9. May Protect Cognitive Health
Taurine may offer neuroprotection through various mechanisms. It helps preserve brain function by offering protection against the harmful effects of various disorders that can otherwise impact cognitive health. It also helps maintain the calcium balance in the body and controls inhibitory neurotransmission (the process in which the brain’s chemicals tell the nerve cells to slow down their signals). These functions are critical for brain health. Taurine levels are often disrupted in metabolic and neurodegenerative disorders, impacting the brain’s well-being. But, taurine supplementation may help combat this problem (20). However, more scientific research is warranted for a clear understanding of the mechanism by which taurine offers neuroprotection. Consult your doctor before trying taurine supplementation. That’s about the various ways in which taurine benefits your health. As we saw, taurine is not like most of the other amino acids. It has a different purpose. That takes us to the next question – how do you get enough of taurine? What are the food sources? Adults are capable of synthesizing taurine to some extent – with the help of methionine and cysteine, two essential amino acids. Apart from that, we need to look at food sources like:
Fish – They contain high levels of taurine. These include whole capelin (6.17 grams per 1 kilo), cooked dungeness crab (5.94 grams per 1 kilo), whole mackerel (9.29 grams per 1 kilo), and Alaskan salmon fillets (4.40 grams per 1 kilo). Meat – Deboned beef (197 mg per 1 kilo), beef liver (2.35 grams per 1 kilo), lamb (3.67 grams per 1 kilo), and chicken liver (6.67 grams per 1 kilo). Sea Algae And Plants – Sea algae contains some taurine, though vegetables grown on land contain none.
What if you are a vegetarian? What if you don’t have access to these limited food sources of taurine? Then, you may want to check out supplements.
What About Taurine Supplements (And Energy Drinks)?
If you are a strict vegetarian or a vegan, you can get your daily dose of taurine through supplements. You can also go for supplements if you are an athlete looking to improve your performance. But when we say supplements, we don’t necessarily mean energy drinks. Though they contain high amounts of taurine, energy drinks also contain other ingredients (like caffeine and sugar) in undesirably excess quantities. Too much of caffeine can elevate blood pressure, and excess sugar can wreak havoc on your health. So, we recommend you stay away from energy drinks if your sole objective is to meet your daily taurine needs. You are likely to become deficient in taurine in the following cases:
You are a strict vegetarian or a vegan. You are deficient in methionine or cysteine, which is what the body uses to synthesize taurine. You are deficient in vitamin B6, which is also required by the body for taurine synthesis, Health conditions like cancer, hypertension, diabetes, liver disease, and epilepsyi A condition in which the brain’s nerve cell activity is disrupted, leading to seizures. Trauma or stroke can often trigger it. .
Your taurine dosage should not exceed 3,000 mg per day. Otherwise, complications might arise.
What Are The Side Effects Of Taurine?
Issues With Pregnancy And Breastfeeding
There is not enough information in this regard. Stay safe and avoid use.
Might Aggravate Bipolar Disorder
Some sources suggest taurine may aggravate bipolar disorderi A mental health condition characterized by episodes of abrupt mood swings. Genetics, environment, and brain chemistry may play a role in it. . People with this condition should avoid its use.
Interactions With Lithium
If you are taking lithium, talk to your doctor. Taurine can increase the serum lithium levels and may lead to lithium toxicity. Your dosage must be adjusted accordingly. Is taurine good for anxiety? Yes. Animal studies show that it has significant anti-anxiety activity (21). Is taurine good for sleep and improving sleep quality? Maybe. Animal studies show that it may have sedative properties, which may help improve sleep quality. However, further studies are warranted to support this claim (22). Does taurine increase serotonin? No. Taurine inhibits and controls the release of serotonin (23). Can taurine cause kidney damage? Maybe. While taurine regulates many kidney functions and protects against kidney disorders, excess supplementation may cause kidney damage (24), (25). Can you take taurine and magnesium together? Yes. Both supplements work well together and supplement each other’s functions. Can taurine support the immune system? Yes. The benefits of antioxidants present in taurine are many. They aid in reducing oxidative stress, which may help boost the immune system and promote longevity (18).
