Taurine’s Benefits For Heart Health And More

Taurine: An Essential Amino Acid Taurine, found in meat and energy drinks, plays a vital role in hydration, digestion, and overall health. A shortage can lead to kidney problems and eye damage.

Taurine: Research Review

First, what is taurine, beyond being an ingredient in many energy drinks?

It’s an amino acid that many animals, including humans, can synthesize in our bodies. Some other animals—including obligate carnivores such as cats (but not dogs, who are omnivorous by nature) cannot synthesize taurine and must get it from food.

So, as humans are very versatile omnivorous frugivores by nature, we have choices:

  • Synthesize it—no need for any conscious action; it’ll just happen
  • Eat it—by eating meat, which contains taurine
  • Supplement it—by taking supplements, including energy drinks, which generally (but not always) use a bioidentical lab-made taurine. Basically, lab-made taurine is chemically identical to the kind found in meat, it’s just cheaper and doesn’t involve animals as a middleman.

What does it do?

Taurine does a bunch of essential things, including:

  • Maintaining hydration/electrolyte balance in cells
  • Regulating calcium/magnesium balance in cells
  • Forming bile salts, which are needed for digestion
  • Supporting the integrity of the central nervous system
  • Regulating the immune system and antioxidative processes

Thus, a shortage of taurine can lead to such issues as kidney problems, eye tissue damage (since the eyes are a particularly delicate part of the CNS), and cardiomyopathy.

Taurine: A “very essential” amino acid

On the topic of eye health, a 2014 study found that taurine is the most plentiful amino acid in the eye, and helps protect against retinal degeneration, in which they say:

❝We here review the evidence for a role of taurine in retinal ganglion cell survival and studies suggesting that this compound may be involved in the pathophysiology of glaucoma or diabetic retinopathy. Along with other antioxidant molecules, taurine should therefore be seriously reconsidered as a potential treatment for such retinal diseases❞

Taurine for muscles… In more than sports!

We’d be remiss not to mention that taurine is enjoyed by athletes to enhance athletic performance; indeed, it’s one of its main selling-points:

See: Taurine in sports and exercise

But! It’s also useful for simply maintaining skeleto-muscular health in general, and especially in the context of age-related decline and chronic disease:

Taurine: the appeal of a safe amino acid for skeletal muscle disorders

On the topic of safety… How safe is it?

There’s an interesting answer to that question. Within safe dose ranges (we’ll get to that), taurine is not only relatively safe, but also, studies that looked to explore its risks found new benefits in the process. Specifically of interest to us were that it appears to promote better long-term memory, especially as we get older (as taurine levels in the brain decline with age):

Taurine, Caffeine, and Energy Drinks: Reviewing the Risks to the Adolescent Brain

^Notwithstanding the title, we assure you, the research got there; they said:

❝Interestingly, the levels of taurine in the brain decreased significantly with age, which led to numerous studies investigating the potential neuroprotective effects of supplemental taurine in several different experimental models❞

What experimental models were those? These ones:

…which were all animal studies, however.

The same systematic review also noted that not only was more research needed on humans, but also, existing studies have had a strong bias to male physiology (in both human and assorted other animal studies), so more diverse study is needed too.

What are the safe dose ranges?

Before we get to toxicity, let’s look at some therapeutic doses. In particular, some studies that found that 500mg 3x daily, i.e. 1.5g total daily, had benefits for heart health:

Bottom line on safety: 3g/day has been found to be safe:

  • Stop Cancer 20 Years Ago

    Dr. Jenn Simmons shares vital tips on preventing cancer and inflammation, advocating for lifestyle changes and proactive health management at any age.

    Get Abreast And Keep Abreast

    This is Dr. Jenn Simmons. Her specialization is integrative oncology, as she—then a breast cancer surgeon—got breast cancer, decided the system wasn’t nearly as good from the patients’ side of things as from the doctors’ side, and took to educate herself, and now others, on how things can be better.

    What does she want us to know?

    Start now

    If you have breast cancer, the best time to start adjusting your lifestyle might be 20 years ago, but the second-best time is now. We realize our readers with breast cancer (or a history thereof) probably have indeed started already—all strength to you.

    What this means for those of us without breast cancer (or a history therof) is: start now

    Even if you don’t have a genetic risk factor, even if there’s no history of it in your family, there’s just no reason not to start now.

    Start what, you ask? Taking away its roots. And how?

    Inflammation as the root of cancer

    To oversimplify: cancer occurs because an accidentally immortal cell replicates and replicates and replicates and takes any nearby resources to keep on going. While science doesn’t know all the details of how this happens, it is a factor of genetic mutation (itself a normal process, without which evolution would be impossible), something which in turn is accelerated by damage to the DNA. The damage to the DNA? That occurs (often as not) as a result of cellular oxidation. Cellular oxidation is far from the only genotoxic thing out there, and a lot of non-food “this thing causes cancer” warnings are usually about other kinds of genotoxicity. But cellular oxidation is a big one, and it’s one that we can fight vigorously with our lifestyle.

    Because cellular oxidation and inflammation go hand-in-hand, reducing one tends to reduce the other. That’s why so often you’ll see in our Research Review Monday features, a line that goes something like:

    “and now for those things that usually come together: antioxidant, anti-inflammatory, anticancer, and anti-aging”

    So, fight inflammation now, and have a reduced risk of a lot of other woes later.

    See: How to Prevent (or Reduce) Inflammation

    Don’t settle for “normal”

    People are told, correctly but not always helpfully, such things as:

    • It’s normal to have less energy at your age
    • It’s normal to have a weaker immune system at your age
    • It’s normal to be at a higher risk of diabetes, heart disease, etc

    …and many more. And these things are true! But that doesn’t mean we have to settle for them.

    We can be all the way over on the healthy end of the distribution curve. We can do that!

    (so can everyone else, given sufficient opportunity and resources, because health is not a zero-sum game)

    If we’re going to get a cancer diagnosis, then our 60s are the decade where we’re most likely to get it. Earlier than that and the risk is extant but lower; later than that and technically the risk increases, but we probably got it already in our 60s.

    So, if we be younger than 60, then now’s a good time to prepare to hit the ground running when we get there. And if we missed that chance, then again, the second-best time is now:

    See: Focusing On Health In Our Sixties

    Fast to live

    Of course, anything can happen to anyone at any age (alas), but this is about the benefits of living a fasting lifestyle—that is to say, not just fasting for a 4-week health kick or something, but making it one’s “new normal” and just continuing it for life.

    This doesn’t mean “never eat”, of course, but it does mean “practice intermittent fasting, if you can”—something that Dr. Simmons strongly advocates.

    See: Intermittent Fasting: We Sort The Science From The Hype

    While this calls back to the previous “fight inflammation”, it deserves its own mention here as a very specific way of fighting it.

    It’s never too late

    All of the advices that go before a cancer diagnosis, continue to stand afterwards too. There is no point of “well, I already have cancer, so what’s the harm in…?”

    The harm in it after a diagnosis will be the same as the harm before. When it comes to lifestyle, preventing a cancer and preventing it from spreading are very much the same thing, which is also the same as shrinking it. Basically, if it’s anticancer, it’s anticancer, no matter whether it’s before, during, or after.

    Dr. Simmons has seen too many patients get a diagnosis, and place their lives squarely in the hands of doctors, when doctors can only do so much.

    Instead, Dr. Simmons recommends taking charge of your health as best you are able, today and onwards, no matter what. And that means two things:

    1. Knowing stuff
    2. Doing stuff

    So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.
