- 0:00Here is how to keep your telomeres nice and long and healthy on the molecular level.
- 0:03I'm a pancreatic cancer researcher, so let me get into the science behind it.
- 0:06Telemeres are little protective caps on the ends of your chromosomes.
- 0:09Think of them like plastic tips on the end of shoelaces.
- 0:11It prevents your DNA from fraying and unwinding every time your cell has to divide.
- 0:15And every time a cell needs to divide, our telomeres are shrinking.
- 0:19When it's too short, that's it for the cell.
- 0:20It's going to either pass away, or it's going to enter a retirement phase where it's not going to work.
- 0:25It's just sitting there.
- 0:26And the length of your telomeres is very tightly linked to how long you will live.
- 0:29This is a very critical phenomenon that has been recently discovered.
- 0:32And to keep your telomeres nice and healthy and long, that is where anti-aging NAD comes into play.
- 0:37NAD stands for nicotinamide adenine dinucleotide.
- 0:39This is a very important coenzyme that we all possess, and it plays a role in over 500 different types of sub-pathways related to anti-aging and longevity.
- 0:46One of its main roles is to activate a family protein called sertuins.
- 0:50These proteins are very critical for promoting the health and longevity of telomeres.
- 0:54Sertuins can either rebuild telomeres, or they protect them from further damage.
- 0:57NAD is also linked to DNA repair mechanisms, because it activates another family of proteins called PARPs.
- 1:03And these proteins help detect and also repair DNA, including telomeres.
- 1:07Lastly, NAD also plays a role in oxidative stress.
- 1:10It's a strong antioxidant agent, so it's going to clear out free radicals from the environment.
- 1:14And free radicals are harmful byproducts created by our bodies in response to pollution, stress, disease, and aging,
- 1:19and that can have an effect on telomere length as well.
- 1:21So by increasing NAD, that's going to reduce oxidative stress, and it's going to keep your telomeres very nice and healthy.
- 1:26I know that was a lot of science. I hope you can believe me. I really try to make it simple.
- 1:30But basically, NAD is very helpful for promoting the longevity and health of your telomeres.
- 1:35And that's going to help you stay nice and long and healthy.
- 1:37So if you'd like to try it out, I actually take the one from Categor. This is liposomal NAD.
- 1:40And it also has resveratrol, which is a strong antioxidant agent.
- 1:43So if you'd like to check it out, I'm going to drop the link right over here.
- 1:45That is their official store where I get it from.
- 1:47And if you have any questions, guys, I know that was a lot of science and it was very difficult,
- 1:50but let me know in the comment section. I'll be happy to clear it out for you.
Telomeres, NAD, and anti-aging supplements: what TikTok gets wrong
Quick answer
The creator accurately describes telomere shortening as a marker of cellular aging and correctly identifies that sirtuins and PARPs are NAD+-dependent proteins involved in genome maintenance. However, no peer-reviewed human clinical trial has demonstrated that oral NAD+ supplementation meaningfully slows telomere attrition or extends healthy lifespan. The product recommendation at the end of the video goes well beyond what the cited mechanisms can support.

Page-specific review note
What this exact clip is really saying
This FormBlends review is specific to "Telomeres, NAD, and anti-aging supplements: what TikTok gets wrong" from Drew Reviews. We read the clip as a Peptide social video fact-checks claim about NAD+ Peptide Complex, then separate the useful signal from what a short social video cannot prove. The page-specific claim focus is: The creator accurately describes telomere shortening as a marker of cellular aging and correctly identifies that sirtuins and PARPs are NAD+-dependent proteins involved in genome maintenance.
The reason this review is not generic is the source wording and the canonical claim label "peptides what are telomeres and how you can keep them longer telomere." In this clip, the useful excerpt is: "Here is how to keep your telomeres nice and long and healthy on the molecular level." That wording changes the review because it points to NAD+ Peptide Complex safety, access, evidence, and fit, not a one-size-fits-all protocol.
The source trail for this page is checked against NAD+ metabolism and its roles in cellular processes during ageing (2021), Nicotinamide mononucleotide increases muscle insulin sensitivity in prediabetic women (2021), and Chronic nicotinamide riboside supplementation is well-tolerated and elevates NAD+ in healthy middle-aged and older adults (2018), plus the creator's own wording. NAD+ Peptide Complex still needs an eligibility review, medication-interaction screen, access check, and quality-control review before anyone treats a social clip as medical advice.

What it helps with
- The creator accurately describes telomere shortening as a marker of cellular aging and correctly identifies that sirtuins and PARPs are NAD+-dependent proteins involved in genome maintenance. However, no peer-reviewed human clinical trial has demonstrated that oral NAD+ supplementation meaningfully slows telomere attrition or extends healthy lifespan. The product recommendation at the end of the video goes well beyond what the cited mechanisms can support.
- Telomere biology is well-established science dating to the 1970s and 1980s, not a recent discovery. Elizabeth Blackburn received the Nobel Prize for telomere research in 2009.
- SIRT6, an NAD+-dependent sirtuin, does play a documented role in telomere maintenance in cell studies (Tennen et al., 2013), but this does not mean a supplement produces the same effect in a living person.
What it may miss
- It may not cover eligibility, contraindications, medication interactions, lab history, or dose escalation.
- NAD+ Peptide Complex decisions still need source quality, legal access, and provider oversight checks.
- Social video captions rarely show the full evidence base behind a claim.
Best next step
Compare the claim against the NAD+ Peptide Complex guide, cost path, safety notes, and provider review before acting.

Our take · Written by FormBlends editorial team · Reviewed by FormBlends Medical Team · This is not a transcript. It is our independent review of the video above.
What did @drew.review actually say?
The creator, who identifies as a pancreatic cancer researcher, argues that NAD+ keeps telomeres "nice and long and healthy" by activating sirtuins and PARPs, reducing oxidative stress, and that taking a liposomal NAD+ supplement with resveratrol is a practical way to support this. They close with a product link.
The core biological claims are not invented. Sirtuins do interact with telomere maintenance, PARPs do assist DNA repair, and NAD+ is genuinely involved in both pathways. The problem is the leap from those cellular mechanisms to "take this supplement and protect your telomeres." That leap is not supported by the current evidence, and the video does not acknowledge that gap at all.
Does the science back this up?
Partially, and only at the mechanistic level. The clinical evidence that oral NAD+ precursors meaningfully extend or protect telomeres in humans is thin to nonexistent right now.
Yes, sirtuins (specifically SIRT1 and SIRT6) have been shown to regulate telomere integrity in cell and animal studies. A 2013 paper by Tennen et al. in Frontiers in Aging Neuroscience documented SIRT6's role in telomere maintenance. And NAD+ does feed into that pathway, no argument there. PARPs, particularly PARP1, are well-documented DNA damage sensors that depend on NAD+ as a substrate (Bai and Cantó, 2012, Cell Metabolism).
But here is what the video skips: NAD+ levels in a cell are tightly regulated. Swallowing a liposomal capsule does not guarantee intracellular NAD+ rises enough to drive meaningful sirtuin or PARP activity in the right tissues. A 2023 review in Nature Aging (Yoshino et al.) noted that NAD+ bioavailability from oral precursors varies significantly between tissues and individuals, and telomere-specific outcomes in humans remain unstudied at the clinical trial level.
What did they get wrong (or right)?
Credit where it is due: the shoelace aglet analogy is accurate and widely used in the literature. Telomere shortening as a marker of cellular aging is real science, not fringe content. The claim that "the length of your telomeres is very tightly linked to how long you will live" is broadly supported by epidemiological data, though the causality debate is still active (Arsenis et al., 2017, Journal of Aging Research).
What they got wrong, or at least overclaimed:
- Sirtuins do not "rebuild" telomeres. They protect them and support telomerase activity indirectly. Saying sirtuins "rebuild" telomeres overstates what the evidence shows.
- NAD+ is not "a strong antioxidant agent" in the conventional sense. It participates in redox reactions and supports antioxidant enzyme systems, but calling NAD+ itself a direct free radical scavenger is chemically imprecise.
- The claim that this is "a very critical phenomenon that has been recently discovered" misrepresents the timeline. Telomere biology has been studied for decades. Elizabeth Blackburn won the Nobel Prize for it in 2009. Framing it as a recent discovery suggests novelty that is not there.
- The product pitch is unsupported by the science presented. Nothing in the mechanistic data the creator cites establishes that this specific supplement extends telomeres in living humans.
What should you actually know?
Telomere biology is real and worth understanding. The supplement pitch attached to it is not supported by human clinical trial data, and that distinction matters a lot.
If you are considering NAD+ supplementation for longevity purposes, the honest picture is this: preclinical and some early human data suggest NAD+ precursors like NMN and NR can raise NAD+ levels in blood (Trammell et al., 2016, Nature Communications), but whether that translates to telomere protection, cellular rejuvenation, or longer life in humans is genuinely unknown. The studies do not exist yet at sufficient scale or duration.
Resveratrol, which the product also contains, has an even rockier track record. Early excitement from Sinclair lab research on sirtuin activation was followed by replication failures and significant scientific controversy. The FDA has not approved any NAD+ precursor or resveratrol product for antiaging indications.
If you are over 40 and concerned about cellular aging, the interventions with the strongest human evidence remain consistent aerobic exercise, sleep quality, not smoking, and caloric moderation. Those are not as exciting as a supplement link, but the data behind them is substantially more robust.
