Telomeres and Aging

In our opinion the cause of aging is simple: it is telomere shortening.

Telomeres are little caps at the end of each of our chromosomes. When our cells divide, the DNA in those chromosomes has to be copied. During this process, the last little bit of the strand - the tip of the telomere - does not get copied and so our telomeres shorten over our lifetimes. This is often referred to as the end-replication problem, but in our opinion it is a 'problem' that is by design.

You can read why we believe in the telomere theory of aging here or you can read this brief description about it. But to make a long story short, as telomeres shorten, the cells they inhabit become 'older' and more dysfunctional. 1 They divide less frequently.2 Stem cells produce new copies less frequently, and at a certain point not at all.3 As a result of all this, our eyesight begins to fail, our skin becomes less elastic4, our immune systems become less effective5 and a host of other changes typically associated with aging begin to take place6.

What is Telomere Guard?



A blend of thoroughly-researched nutraceuticals, each independently shown in public studies to slow telomere shortening.


A revolution in life extension!

The Triumphs and Challenges of Telomerase

Telomerase is an enzyme that extends telomeres. The gene that codes for it is in every one of our cells, but not 'expressed' in most of them, which means that telomerase is not made from it. Over the last several years, the telomere-based life extension conversation has centered largely around the topic of turning this gene on - 'telomerase activation'. It was believed by some that when we could do that, then telomeres could be lengthened in cells all over the body and aging could be conquered.

However, recent in vivo studies of telomerase activation in humans and mice have shown that telomerase activation did not increase average telomere length and in fact did not even slow down telomere shortening in a statistically significant way9. It did lengthen critically short telomeres10, which was an enormous success, and served to reverse some aspects of aging as a result, most notably in the remodeling of the immune system.

Telomerase is the enzyme that extends telomeres, and one of the few known natural processes by which they can be extended. But it is now clear that there are more regulation mechanisms at work in the cell that need to be unlocked before we can put it to use fully. We do not today have a way to extend average telomere length. What is worse, however, is that we do not even appear to have an effective way to counter the inevitable shortening of average telomere length over long periods of time.

A New Approach

This is where Telomere Guard comes in. At the same time as this research in telomerase activation was going on, the excitement surrounding telomeres was causing different scientists across the world to ask whether anything can slow telomere shortening down. Most substances had no effect. But as it turned out, some natural compounds did in fact make a very significant difference.

Telomere Guard takes advantage of these discoveries by combining the most promising of these neutraceuticals into one powerful product. Now for the first time you can slow down aging at its true source - telomere shortening.

Scientists have found a number of nutriceuticals that appear to slow telomere shortening down dramatically.

Telomere Guard takes advantage of these discoveries by combining the most promising of them into one powerful product.

In this study, pretreatment of cells with alpha-tocopherol (the most commonly sold component of Vitamin E) delayed the telomere shortening associated with subsequent hydrogen peroxide treatment.

Asc-2-O-phosphate (Asc2P)

Shortening rate reduction


Asc-2-O-phosphate (Asc2P) is a rare form of Vitamin C. In this study, it was shown that repetitive addition of Asc2P to human endothelial cells in vitro slowed telomere shortening by a dramatic 52-62%. Regular Vitamin C had no effect. Read more.


Shortening rate reduction

Telomerase Activator

In this study, a group of three month old mice received purslane subcutaneously (by shot) for only two weeks. The Purslane group (with 2.5 mg/kg-day) had increased telomerase activity and the telomeres of the brain cells of the mice after that period were 27kb as opposed to 23kb in the control group - a very dramatic difference for only 2 weeks of treatment. Read more.


Shortening rate reduction


In this study, cells grown with continuous exposure to carnosine exhibited a 32% slower telomere shortening rate (loss of 26.8 versus 39.4 TRFs) and extended lifespan, all in the face of a higher reproduction/cell doubling rate. Read more.

Terminalia Chebula

Shortening rate reduction


In one study, the telomere shortening rate of Terminalia Chebula treated cells was 192 bp/PDL, as compared to the control group's 342 bp/PDL - a rate reduction of 45%. Read more.


Telomerase Activator

Tocotrienols are part of the group of phytochemicals known together as Vitamin E, but not included in most Vitamin E supplements. In this in vitro study, the authors concluded that "gamma-tocotrienol protects against oxidative stress-induced cellular ageing by modulating the telomere length possibly via telomerase". Cells were exposed for 24 hours to gamma-tocotrienol before and/or after 2 hour exposure to hydrogen peroxide (H2O2). At the optimal dose, telomere lengths of treated cells appear to have been roughly 16% longer than controls after only this very short period of exposure.

Green Tea

In this study, consumption of green tea was correlated with longer telomeres in men . Out of a sample of over 2000 Chinese participants, those in the highest quartile of tea consumption (greater than 750 mL/day) had an average of 0.46 kb longer telomeres than those in the lowest quartile (less than 70 mL/day). This is approximately equivalent to 5 years of life.

N-Acetyl Cysteine (NAC)

In this in vitro study, the authors found that the "onset of replicative senescence [was] delayed by incubation with N-Acetyl Cysteine".


Shortening rate reduction


High levels of homocysteine have been shown to triple the rate of reduction in telomere length during cell division. High homocysteine levels are the result of poor methylation the severity of which varies from person to person. However, it has long been known that these supplements can help support healthy homocysteine levels.

  • Folic Acid
  • Vitamin B12
  • Pyridoxine (B6)
  • Riboflavin (B2)
  • TMG (trimethylglycine)


Part of the job of the telomere is to 'cap' the chromosome in order to protect it from damage. But nothing caps the telomere itself. Because of this, telomeres are vulnerable to damage, particularly from oxidative stress, a phenomemon that has been discovered recently to dramatically accelerate telomere shorteing.11 Because of this we have included three powerful anti-oxidants: Blueberry, Acai and Grapeseed extract.

Things We Excluded

Omega 3s

In this study, patients who were in the lower quartile of marine Omega-3 fatty acid levels had over triple the rate in telomere length reduction (13 T/S units) over a five-year span than patients in the upper quartile of marine Omega-3 fatty acid levels (5 T/S units). Read more.

We did not include Omega 3s in Telomere Guard because it was not cost and volume effective to offer it in the amounts we would recommend (700mg per day) in powder form. We also thought that many people interested in life extension would already be taking this by oil or softgel capsule. So we left it out. But, the above study indicates that it may be very effective in slowing telomere shortening so make sure to take an Omega 3 supplement in conjunction with Telomere Guard. Naturally, we recommend ours.

    In the above study, skin was grown onto the back of a mouse. Skin reconstitution from early passage (20 population doublings) cells with longer telomeres deomonstrated good adhesion, complex dermal-epidermal interdigitiation, and good resistance to sheer strees. There were no microbullae or splitting between the two layers. There results were equivalent to results observed clinically in young skin.
    Late-passage (85 population doubling) human dermal cells that had short telomeres showed poor dermal-epidermal adhesion, simplified interdigiations, and a high sensitivity to sheer strees ther was extensive splitting and blistering (microbullae) along this junction. These results are equivalent to results observed clinically in older skin.

    "Paradoxically, although ~40% of subjects showed an increase in mean telomere length over time, on average across all subjects there was a nonsignificant decline in mean telomere length. However, we speculate this effect is explained by cell dynamics and the fact that telomerase preferentially lengthens the shortest telomeres."
