- 0:00Let me tell you exactly how I recommend NAD supplementation based on your aid and why it matters.
- 0:05So I'm Dr. Janelle Dua, a Yale-trained physician, triple-borded in internal medicine, obesity medicine, and lifestyle medicine.
- 0:13So cellular biology, that's kind of my domain.
- 0:16So here's the quick science.
- 0:17NAD is a critical molecule found in every cell in your body.
- 0:21It's main job converting the food you eat into usable energy, ATP.
- 0:26But it also plays a key role, that is, in DNA repair, regulating your circadian rhythm, reducing inflammation,
- 0:33clearing brain fog, and even helping with muscle recovery.
- 0:36But here's the catch.
- 0:37By the time you hit middle age, your NAD levels have already dropped by half.
- 0:42That decline impacts your energy, your skin, your focus, everything.
- 0:46That's why supplementing NAD becomes essential, and the brand I personally take and recommend is nature newborn.
- 0:52Here's why.
- 0:53They don't just use NR, nicotinamide riboside, to boost NAD.
- 0:57They've also added calcium alpha-ketoglutarate, AKG, and that's the true game changer.
- 1:02While NR increases NAD, AKG slows down the rate at which your body uses it.
- 1:08So it's like turning on the faucet and plugging the sink so your levels go up and actually stay up.
- 1:13This combo is more bioavailable, fast-acting, and way more potent than most formulas on the market.
- 1:19To my knowledge, nature newborn is the first TikTok-featured brand to do this.
- 1:23So what do I recommend?
- 1:24If you're under 20, you could stick with a good multivitamin.
- 1:27But if you're in your mid-30s or older, 1,000 milligrams of NAD booster with Reservatrol and AKG,
- 1:33like this, can be a fantastic tool for cellular support, energy, recovery, and yes, even better
- 1:39sleep. NAD regulates your circadian rhythm, helps reduce fatigue, supports muscle recovery,
- 1:45and helps with mental clarity.
- 1:47So if you're noticing fine lines, brain fog, or just dragging through the day,
- 1:51this could be exactly what your body needs. I've linked this one, the one I trust and use right here.
NAD+ boosters and resveratrol: what the science actually supports
Quick answer
Dr. Dua promotes a commercially available NR plus AKG plus resveratrol stack to a general audience, recommending a specific 1,000 mg dose for adults over 35 and framing it as addressing fatigue, brain fog, skin aging, and sleep quality. While NAD+ precursor therapy is an active area of clinical research, the combined formulation she endorses lacks peer-reviewed comparative efficacy data, and the claim that AKG functionally inhibits NAD+ catabolism in humans is not yet supported by published human trials. The video constitutes a direct product endorsement from a named physician and should be evaluated under FTC endorsement guidelines as well as platform health claim policies.

Page-specific review note
What this exact clip is really saying
This FormBlends review is specific to "NAD+ boosters and resveratrol: what the science actually supports" from Dr. J. 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: Dr.
The reason this review is not generic is the source wording and the canonical claim label "peptides if you re constantly tired feeling foggy or noticing prematu." In this clip, the useful excerpt is: "Let me tell you exactly how I recommend NAD supplementation based on your aid and why it matters." 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 The human peptide GHK-Cu in prevention of oxidative stress and degenerative conditions of aging (2015), Effects of glycyl-histidyl-lysine-Cu on wound healing (Search), and Copper peptide and skin remodeling literature (Search), 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
- Dr. Dua promotes a commercially available NR plus AKG plus resveratrol stack to a general audience, recommending a specific 1,000 mg dose for adults over 35 and framing it as addressing fatigue, brain fog, skin aging, and sleep quality. While NAD+ precursor therapy is an active area of clinical research, the combined formulation she endorses lacks peer-reviewed comparative efficacy data, and the claim that AKG functionally inhibits NAD+ catabolism in humans is not yet supported by published human trials. The video constitutes a direct product endorsement from a named physician and should be evaluated under FTC endorsement guidelines as well as platform health claim policies.
- NAD+ does decline with age in human tissues, but the widely-cited '50% drop by middle age' is a simplification. Decline rates vary by tissue, and most robust data come from animal studies or small human samples.
- NR (nicotinamide riboside) is the best-supported oral NAD+ precursor. Martens et al. (2018, Nature Communications) confirmed it raises blood NAD+ in older adults in a randomized trial, though translating that into symptom improvement is a separate and less-proven question.
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.

- Physician endorsement of a specific commercial supplement brand on social media triggers FTC endorsement disclosure requirements. The video does not visibly disclose a paid relationship, which warrants scrutiny independent of the science.
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 @drj1189 actually say?
Dr. Janelle Dua, who identifies as a Yale-trained physician board-certified in internal medicine, obesity medicine, and lifestyle medicine, made several interconnected claims in this video. The core pitch: NAD levels drop by half by middle age, that decline drives fatigue, brain fog, skin aging, and poor sleep, and that supplementing with a specific product combining nicotinamide riboside (NR), resveratrol, and calcium alpha-ketoglutarate (AKG) can address all of it.
She described AKG as something that "slows down the rate at which your body uses" NAD, using the analogy of "turning on the faucet and plugging the sink." She recommended 1,000 mg of this combination for anyone in their mid-30s or older. She also described the brand Nature Newborn as "the first TikTok-featured brand" to use this NR plus AKG combination, which is a claim so specific it deserves its own scrutiny.
Does the science back this up?
Some of it does, but the parts that matter most are thinner than the confident delivery suggests. NAD+ decline with age is real and reasonably well-documented. The claim that AKG specifically "slows NAD consumption" is where the science gets murky fast.
NAD+ does decline with age in tissues. Studies including work by Schultz and Sinclair (2016, Science) confirmed this and linked it to mitochondrial dysfunction. NR as a precursor to boost NAD+ has human trial support, including a randomized trial by Martens et al. (2018, Nature Communications) showing NR supplementation raised whole-blood NAD+ in older adults. So the basic premise of using an NAD precursor is not invented.
Resveratrol's role is murkier. Early Sinclair lab work on sirtuins generated enormous excitement, but subsequent human trials have been inconsistent. A Cochrane-adjacent review by Pollack (2012, Ageing Research Reviews) found limited translatable evidence in humans.
AKG is the biggest stretch. Alpha-ketoglutarate has been studied as a longevity compound, including a 2020 paper by Shahmirzadi et al. in Cell Metabolism showing lifespan extension in mice. But the specific mechanism that it "plugs the sink" on NAD consumption in humans is not established by peer-reviewed evidence. That faucet-and-sink analogy is marketing language dressed up as biochemistry.
What did they get wrong (or right)?
Credit where it is due: the foundational biology is accurate. NAD+ is genuinely involved in ATP production, DNA repair via PARP enzymes, and circadian regulation through SIRT1 pathways. These are not invented roles. Saying NAD "regulates your circadian rhythm" is supported by research including work by Nakahata et al. (2009, Cell).
What went wrong is the logical leap from real biology to product-specific efficacy claims. The claim that this particular combination is "more bioavailable, fast-acting, and way more potent than most formulas" is unsupported by any cited evidence. No head-to-head comparative trial on Nature Newborn versus other products exists in the public literature.
The "first TikTok-featured brand to do this" framing is not a scientific distinction. It is a marketing claim wearing a white coat.
- Correct: NAD+ declines with age and affects energy metabolism
- Correct: NR is a functional NAD+ precursor with human trial data
- Misleading: AKG specifically inhibits NAD+ consumption in humans is not established
- Inaccurate: Claiming this brand is uniquely superior without comparative data
- Unverifiable: The 1,000 mg dose recommendation lacks a clinical basis specific to this formulation
What should you actually know?
NAD+ precursor supplementation is a legitimate area of research, not fringe pseudoscience. But the gap between "NAD matters biologically" and "this supplement will fix your brain fog and fine lines" is enormous, and this video sprints across that gap without looking down.
NR and NMN (nicotinamide mononucleotide) are the two most-studied oral precursors. Martens et al. (2018) showed NR raised NAD+ in blood, but raising blood NAD+ and improving clinical outcomes are not the same thing. A 2023 randomized trial by Liao et al. in Nature Aging found NMN improved muscle insulin sensitivity in older women but showed modest effects overall.
AKG research is early-stage and largely animal-based. Combining it with NR and calling that combination mechanistically synergistic requires human data that does not yet exist publicly.
The 1,000 mg dose figure offered for anyone over 35 is not drawn from a guideline or established trial protocol. Anyone considering NAD precursor supplementation should discuss it with a clinician who knows their full medical history, not calibrate their dose based on a TikTok recommendation, regardless of the credentials attached to it.
