June 2019 Longevity Review

Posted by Chris Pollyanna , 25 July 2019 · 2,102 views

longevity review supplements senolytics rapamycin nad+

Hello and welcome once again to this month’s longevity update. The big news for June was the release of the second set of human trial results for a senolytic agent, which although did not produce miracles, was nevertheless very encouraging in my opinion.


The big news from me is that I volunteered at Ending Age Related Diseases 2019 in New York on 11th-12th July. I got to be one of the two timekeepers and therefore got to watch all of the presentations and discussions from the front row. It was an amazing, yet exhausting experience – who knew that simply keeping track of time could be so tiring? I will mention more next month, as I want to get this update out, having originally planned to get it out before I went. I had also planned to live tweet the event but there wasn’t any time – speaking of which…


Follow me on Twitter @ChrisPollyanna1 for the latest updates! ;)


NOTE: I’ve been having trouble linking to the science journal hacking site sci-hub.tw, so am only including Full Text links to articles not behind a paywall. I have still been able to download most of them, so if there are any that you are after, I can send them upon request.


June Round-Up

  • Senolytics are the most promising near term rejuvenatory therapeutics. If the data from mice in any way translates to humans, then their impact will be profound. Here is the second set of preliminary results in humans (the first being in January with a different drug combo). This is from a commercial company hoping to bring it to market against arthritis initially. This was a phase 1 study, so it was meant to check for any potential side effects, not how well it worked. There were no major side effects and initial indications of a dose response, which is extremely encouraging. To my surprise the longevity community didn’t do cartwheels of joy, but I think most of them didn’t dig into the results or watch the company presentation, which I have included here for the added detail:

  • Even if you were to make it to 110 years of age without suffering any of the major diseases of ageing, something will still get you in the end. That “something” turns out to be amyloidosis, the deposition of amyloid throughout the body, which was found to be the main cause of death among supercentenarians. I realise this must be keeping you awake at night! Fear not however, as the first in human trial of a drug to treat this most pressing of conditions has taken place:

  • Urolithin A is a substance which our gut microbes can produce from a molecule found in pomegranate (ellagitannins) and which might help our mitochondria (the powerhouse of our cells). Urolithin A has been found to increase the lifespan of model organisms, however even more interestingly, the study below was done in humans and although was not aimed at improving lifespan, showed an improvement in their mitochondria. For those of you who like to go down the rabbit hole, I’ve also included a link to a video review of the paper by LEAF, who review a longevity paper every month on their Facebook page:

*Positive Results from Urolithin A Human Trial LEAF Journal Club June edition on Urolithin A paper

  • Here is another study showing that a means of increasing NAD+ in the body (of mice) could increase lifespan by around 16%, this time using a protein, eNAMPT, which declines with age. This is hopeful for those of us who take NAD+ precursors such as Nicotinamide Mononucleuotide (NMN) or Nicotinamide Riboside (NR).

NAMPT Delays Aging and Extends Lifespan in Mice

  • I’ve mentioned many times before about the potential benefits of transferring young blood or plasma to older individuals. Here is a rather different proposition entirely! It turns out that the composition of our gut microbes changes with age, and by transplanting the gut microbes of a young mouse to an old one improves one aspect of ageing:

  • The thymus is a vital organ of our immune system which unfortunately shrinks with age. If the thymus could be rejuvenated, out immune system would improve and reduce the incidence of life threatening infections, which are significant source of mortality for the elderly. Here, scientists have made progress in engineering a man made replacement for the thymus’s decline:

Videos to watch – as I’ve already given a couple of things to watch in the round-up section above, there’s nothing extra this month. Not to mention I didn’t find anything else worth putting in here…

June Supplemental Information


***Disclaimer 1 – As should be self-evident to anyone receiving these emails, I am NOT a doctor or indeed a scientist. All the information pertained within is for information purposes only; use at your own risk. Please consult with a healthcare practitioner if needing medical advice.***


**Disclaimer 2 – In no way should supplements be a replacement for an unhealthy diet or lifestyle. A varied, plant dominant dietary pattern is the cornerstone for health. Try to eat the rainbow – the greater the variety, the greater the benefit. Even though I might take a supplement derived from a plant source, I still eat the plant in question. Also, make sure you move as much as possible – that is what we evolved to do.**


*Also bear in mind that most of the studies mentioned below are in rodents, not humans. Rodents, needless to say, do not always react the same way to drugs as humans do – witness the countless times cancer or another disease has been cured in rodents only to subsequently fail human trials. I have *bolded any human trials.*


Fasting/Dietary Restriction certainly the cheapest & also one of the most effective anti-ageing interventions currently available. It comes in many flavours, but I fast for at least 12 hours every day.

Non-prescription Supplements (in alphabetical order)


Astaxanthin which is behind the pink colour of salmon & shrimp. Considered the most powerful carotinoid, it has anti-oxidative, anti-inflamatory, anti-cancer, neuro-protective and skin-protective qualities. I take 4mg daily.
