TAURINE: USE AND EFFECTIVENESS

 TAURINE: USE AND EFFECTIVENESS








Taurine is a naturally occurring compound found in the body, particularly in tissues such as the heart, brain, and muscles. Over the past few years, it has garnered considerable attention as a supplement, typically used for heart health, exercise performance, and metabolic support. Here’s what the latest peer-reviewed research actually shows, and what you should keep in mind if you’re considering taking it.

Cardiovascular Health
Several meta-analyses and reviews suggest that taurine supplementation may help regulate blood pressure, support healthy blood vessels, and possibly lower the risk of cardiovascular disease. For example, a systematic review published in the Nutrition Journal (2024) found associations between taurine intake and improvements in cardiovascular markers. However, it also notes that there is no consensus yet on the optimal dose or duration of supplementation. Most experts agree that more rigorous studies are needed before taurine can be widely recommended for heart health; however, the current data are promising (Nutrition Journal, 2024, Springer). There’s also evidence that taurine could help with specific issues like hypertension and atherosclerosis (PMC).

Metabolic Effects and Diabetes
Several animal and human studies have investigated taurine’s role in metabolic health, including its impact on glucose and lipid metabolism. Clinical trials involving people with diabetes have yielded some positive results—for example, improvements in blood sugar control—but the findings are still mixed and not strong enough to support broad clinical recommendations at this point (PMC; ScienceDirect).

Exercise Performance
Taurine is also marketed for athletic performance. Reviews and meta-analyses generally report small but measurable improvements in endurance and overall exercise capacity, though these effects are modest and seem to vary depending on dose and individual factors (Springer; Springer).

Other Potential Benefits
Some research suggests that taurine has antioxidant properties and may have anti-aging effects. For instance, a controlled clinical trial in older women found that taurine supplementation helped reduce oxidative stress, which is associated with aging (ScienceDirect). There’s also early evidence suggesting taurine might play a role in liver health and neurological protection, though studies here are still preliminary.

Safety and Dosage
Taurine is considered very safe for most healthy adults. The accepted safe upper limit for supplementation is about 3 grams per day, with very few adverse effects reported at this level (Elsevier; Wiley). Still, as with any supplement, people with health conditions, pregnant or breastfeeding women, and anyone taking medication should talk to their doctor before starting.

Should You Supplement?
If you’re healthy and interested in potential heart or exercise benefits, taurine is generally safe and might be worth a try, especially if your diet is low in taurine-rich foods like seafood and meat. The most substantial evidence right now supports its use in specific groups (like people with hypertension or particular metabolic concerns), and more research is needed before it can be broadly recommended.

Takeaway: Taurine has a solid safety record and shows promise for cardiovascular, exercise, and metabolic health. But it isn’t a cure-all, and decisions about supplementation should be based on your personal health goals and a conversation with a healthcare provider.

B12 MAY HELP PREVENT ALZHEIMER'S DISEASE.

  B12 MAY HELP PREVENT ALZHEIMER'S DISEASE. Worms don't wiggle when they have Alzheimer's disease. Yet something helped worms with the disease hold onto their wiggle in Professor Jessica Tanis's lab at the University of Delaware. In solving the mystery, Tanis and her team have yielded new clues into the potential impact of diet on Alzheimer's, the dreaded degenerative brain disease afflicting more than 6 million Americans. A few years ago, Tanis and her team began investigating factors affecting the onset and progression of Alzheimer's disease. They were doing genetic research with  C. elegans , a tiny soil-dwelling worm subject of numerous studies. Expression of amyloid-beta, a toxic protein implicated in Alzheimer's disease, paralyzes worms within 36 hours of reaching adulthood. While the worms in one petri dish in Tanis's lab were rendered completely immobile, the worms of the same age in the adjacent petri dish still had their wiggle, documented as ...

EXTREME HEAT MAY NEGATIVELY IMPACT COGNITIVE HEALTH

  EXTREME HEAT MAY NEGATIVELY IMPACT COGNITIVE HEALTH          July 2023 was the hottest month, with cities like Phoenix experiencing record-breaking heat waves for weeks. A new study finds that ongoing extreme heat can worsen cognitive decline among vulnerable groups -- particularly Black older adults and those living in poor neighborhoods. "Our research finds that cumulative exposure to extreme heat can undermine cognitive health, but it does so unequally across the population," said Eunyoung Choi, a postdoctoral associate at the NYU School of Global Public Health and the first author of the study, published in the  Journal of Epidemiology and Community Health . Extreme heat is the leading cause of weather-related deaths in the U.S., claiming more lives each year than hurricanes, tornadoes, and lightning combined. Young children and older adults are particularly vulnerable to heat-related illnesses such as heat exhaustion and heat stroke. Recent stud...

Diabetes drugs may reduce the risk of Alzheimer’s.

    Diabetes drugs may reduce the risk of Alzheimer’s. The study finds people taking the drugs have fewer biomarkers, slower cognitive decline. People taking certain drugs to lower blood sugar for type 2 diabetes had less amyloid in the brain, a biomarker of Alzheimer's disease compared to people with type 2 diabetes who are not taking the drugs and those without diabetes. The new study, published in the August 11, 2021, online issue of  Neurology , the medical journal of the American Academy of Neurology, also found people taking these drugs, called dipeptidyl peptidase-4 inhibitors, showed slower cognitive decline than people in the other two groups. In people with type 2 diabetes, the body no longer efficiently uses insulin to control blood sugar. Dipeptidyl peptidase-4 inhibitors, also known as gliptins, can be prescribed when other diabetes drugs do not work. They help control blood sugar when combined with diet and exercise. "People with diabetes have been shown to ...
