Anyone who is interested in trying NMN, I would highly recommend listening to Dr david Sinclair and maybe reading his book called “Lifepsan”. I recently wrote a post about treatments for longevity potentially being able to cure syndromes like PFS and PAS of they are due to epigenetic changes.
Dr David Sinslcair takes 1g of NMN each day. However, if you want to try NMN, you shuold also try 1g of resveretrol with it. NMN is a precursor to NAD which acts like fuel for the sirtuin genes/enzymes. Its this set of genes that provides all the benefits of NMN as they can repair DNA and also reverse DNA methylation etc.
NAD is the fuel for the sirtuins but resveretrol acts like a foot on the accelerator of the sirtuin genes. So they make a great combination. Also, if you take NMN, you need to keep it refrigerated as it can degrade quite easily.
It is highly recommended to take resveretrol and NMN with some greek yoghurt and fats such as olive oil as this signficantly increases the bio-availability/absorption of both of these compounds. I believe the difference in some cases was up to a 5x increase in blood concentrations.
