Sirtuins Anti Aging. Revisited. What they are. Why you should care. How you can benefit

Posted by in categories: biotech/medical, life extension, neuroscience

Good day to you all.

Sirtuins are once again, making headlines. From a longer lifespan, again, through to helping old and dormant hair follicles to grow new hair, and of course a discourse between certain personalities on twitter, they continue to stimulate the interest and promise so much…

So I have decided to follow up my last sirtuins video with this one, Sirtuins revisited.

Here I look at them all from 1 to 7, to see what is being claimed for each one, and then I look at all the ways we can try to bring them all up to optimum so that we can live long, healthy lives, free from the maladies of old age.

I look at lifestyle interventions from exercise, saunas, cold therapies and more, through to diet choices and then finally on to supplements that are available to boost them all further.

So I hope you find it of use and enjoyable, and have a great weekend.


Sirtuins Anti Aging. Revisited.

Following up on my last sirtuins video I have added more information and an extensive list of what each sirtuin does, and what you can do to optimise yourself, and who you should be bothering.
