Scientists Discover That Taurine Promotes Anti-Aging

An you talk more to Pulsetto - how/often/timing of when you use? I’ve been interested in something like that for a sleep optimization perspective.

How long have you had it? I’d want to share it with my wife, would that work or only one app/user?

I’ve only had it a couple of months. My wife and I use it. We just use the app on my phone. It does seem to work, it has different settings and definitely makes you more relaxed and your HRV does increase after you use it.
They have a sleep setting, which I’ve been using when I get insomnia. The one thing I will say though is that while it works, having to sit down and put the thing on every day at least for me is a hard habit to add to my routine.
I think it works, but it’s probably going to end up collecting dust in a drawer, unless you’re really disciplined.


Thanks for this context Paul! How long are the sessions you use it for?

When using for sleep/insomnia has it helped?

Re “sit down”, does one have to sit or can one use while lying down?

Can you talk to this John? Both what techniques you think are promising and also the comment about right vs left.

Sounds like maybe we should be adding the Taurine to our Gatorade instead of coffee?

You can sit and lie down using it. In fact you could just walk around I suppose. I’ve definitely noticed a calming effect if I’m feeling agitated. I think the only reason I don’t use it more often is that I simply forget to do it. You also have to use gel on the electrodes and it’s a bit messy.
I have been waking up around 4am a bit recently and have found it hard to get back to sleep. So I’ve used it for that. The sleep setting is ten minutes. I definitely feel sleepy after using it. The only drawback is that it has a bright flashing light and you have to navigate the app but it seems to work. I haven’t used it consistently enough to be able to give a definitive review of it.

Taurine has been tested to be safe up to 6 g daily. You can go beyond that, it just hasn’t been tested as far as I know. If you feel terrible at a high dosage, either there is another factor at play such as illness or the dose is too high. I would back the dosage down and wait for any symptoms to clear up. Then you can try a higher dosage in a week or two. If the bad side effects come back then you know it’s the dosing.


Thanks Paul. I’ll check it out!

Although there is a vagus nerve on both the left and right side they are not symmetrical and

  • Sleep on the right side
    Lying on the back decreases Vagus Nerve activation, but sleeping on the right side shows greater Vagus Nerve stimulation compared to left side sleeping.

NSDR/Yoga Nidra is one approach to stimulating vagus with a suggested movement before sleep to lie on the right side.

There are various bits of equipment that claim to stimulate vagus. Personally I only use things like meditation/breathing exercises and other aspects of Yoga Nidra (also melatonin administration in various ways).

In the future I might test out some of the vagus stimulation systems, but realistically it is not practical to test too many things at once and vagus is not my current priority.


Yes that’s exactly what I plan to do. Give it another shot at high dosage when I’m feeling great and no colds / bugs running their course in the family to act as confounding variables. Have a strong feeling it was the 10 grams of Taurine. It’s probably a function of body mass too, as I saw upthread some men taking 20+ grams but I’m 5’3”….


Thanks a bunch John. The sleeping in the “right” side is very interesting


I have tended to sleep on my side, but i found rhe lack of symmetry interesting.


I have been aware of the asymmetrical aspect of the vagus nerve for 5 or 6 years from my physician colleagues… some believe it might have something to do with why some people are more prone to get migraine headaches.


When I take 2 – 5 gram of taurine right before I go to bed, then I sleep deeply but tend to wake up in the middle of the night or I wake up to early in the morning. If I wake up in the middle of the night, then I take another dose of taurine and go back to sleep. (In my case, it takes time for the Taurine to bring me back to sleep. Taurine is not a substance that works quickly on me.)

If I wake up later during the night (like after 3 AM or so), then I don’t take taurine, this since taurine tends to give me brain fog for quite some hours the coming day.

For me it might be optimal not to take taurine before I go to bed, but to take it when I wake up in the early part of the night. Then first, I get my natural sleep and then I get Taurine enhanced sleep.

Taurine is intriguing. Small doses and larger doses seem to provide me with different dose responses.

This is in line with what is said in a paper previously posted in this thread. I think it is valuable information so here I repost the link.

how to reap the benefits from Taurine is a work in progress. But it seem clear, that to regain youthful levels, and improve healthspan, there is a need to take at least 2,5 gram.


From my experience, the waking early ceases with continued use. Your sides generally mimick mine, I feel groggy when taking taurine during the day or late into the night.

I am back to taking taurine, but am only taking 2g to avoid these side effects. I do plan on bumping it slowly.


I have been wondering why my RHR is 10 bpm higher when I sleep on my right side. I tend to sleep on my left, and my Oura ring thinks I’m sick or something when I sleep on my right side.

I have read that it is healthier to sleep on the left side. But, for whatever reason, I simply cannot go to sleep on my left side. So, I sleep primarily on my right side. Sometimes I become uncomfortable sleeping on my right side and then I can turn over and sleep for an hour or two on my left side.


Interesting, so you remember the rationale?

For me it is much healthier to sleep on my left side because my wife sleeps on my right….


I don’t think there is much science behind which is best. But, I believe it goes something like this:
(From a reply to a YouTube video):
" If you’re a person with a heart condition you’ll likely want to sleep on your right side to keep the pressure off your heart. If you’re a person who doesn’t have a heart condition but suffers from acid reflux sleeping on your left side would likely be your best option to keep the acid from backing up into your esophagus"
