February 2019 Longevity Review

longevity review young plasma nmn nad+ supplements crispr

Hello and welcome to this month’s longevity update. As I scour the internet for the latest news on the science of anti-ageing I predominantly use scientific news sites and publications, however I also check out non-traditional sources such as blogs and their comment sections to find out hints as to what may be coming down the road. I want to share an exciting example of this.


A few months ago, in the comment section of a blog, somebody posted that their lab had successfully managed to rejuvenate old rats by using a fraction of young blood plasma. Young blood/plasma, along with epigenetic reprogramming, is one of the few anti-aging strategies which has the potential to be a “silver bullet” to cure ageing. The blog poster has now shared their first results with the blog in question. If the results are to be believed, and it’s a big IF as the study only involved 6 rats and has not yet been peer-reviewed, let alone replicated, then it could portend human rejuvenation being less than a decade away.
Rumors of Age Reversal: The Plasma Fraction Cure Study Results


On a personal level, in the past month I’ve gone “all in” on anti-ageing supplements with the start of me taking Rapamycin (2.5mg/weekly) & Metformin (500mg/daily). Not expecting anything myself, but I want to be confident about their safety before giving them to my parents. I bought blood pressure and blood glucose monitors to try to get some biomarkers for what it’s worth.


Below you will find February’s most interesting developments as well as a couple of really cool podcasts. Furthermore, in the supplemental attachment there are some human studies of Curcumin, Nicotinamide Riboside (NR) and Resveratrol – along with an avalanche of promising studies on Rapamycin amongst others.
February Round-Up


Young bone marrow rejuvenates aging mouse brains - Transplanting bone marrow from young lab mice to old mice preserves memory and learning skills. This is similar to using “young blood” to treat ageing, but instead of transfusing blood, the blood producing cells have been transplanted. Full Text


CRISPR/Cas9 therapy can suppress aging, enhance health and extend life span in mice - Researchers have developed a new gene therapy to help decelerate the aging process. The findings highlight a novel CRISPR/Cas9 genome-editing therapy that can suppress the accelerated aging observed in mice with Hutchinson-Gilford progeria syndrome, a rare genetic disorder that also afflicts humans. This is the first time to my knowledge that CRISPR/Cas9 gene editing has been used in the ageing field – exciting stuff! Full text


New molecules reverse memory loss linked to depression, aging - New therapeutic molecules show promise in reversing the memory loss linked to depression and aging. These molecules not only rapidly improve symptoms, but remarkably, also appear to renew the underlying brain impairments causing memory loss in preclinical models. Full Text


Inhibition of ‘jumping genes’ promotes healthy ageing - DNA sequences called retrotransposons can copy themselves and reintegrate at new sites in the genome, causing damage. It now seems that inhibiting this process can prevent age-related health decline in mice. Full Text


Skin Repair Eliminates ‘Inflamm-Aging’ Linked to Chronic Disease In a pilot study, treatment with a full-body reparative skin cream reduced inflammatory cytokines linked to Alzheimer’s, Heart Disease and Diabetes. Time to slap on the skin cream! Full Text
Below are two podcasts with leading anti-ageing researcher David Sinclair, who shot to fame in the mid-2000s with the red wine molecule Resveratrol, which lengthened the life of obese mice. Since then his lab has worked on the NAD+ pathway, which is vital for numerous repair processes and declines with age, and small molecules which can return NAD+ to youthful levels. He has been a big proponent of Nicotinamide Mononucleotide (NMN) to do so.


The Joe Roggan Experience – an accessible and entertaining podcast for the layman. This show caused a surge in NMN sales.


Peter Attia – a much more technical podcast getting into the nitty-gritty NAD+, NMN & ageing in general.

Supplemental Information


**Disclaimer – 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.**


*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 – 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, neuro-protective and skin-protective qualities. I take 4mg daily.

Curcumin – the spice which gives curries their yellow colour. Anti-inflammatory and neuroprotective. I take 1 gram a day. Needs gto be
taken with black pepper to improve bio-availability.
