Why does NAD+ matter more after 40?
By midlife, NAD+ in several tissues is lower, partly because NAD-consuming enzymes such as CD38 rise with age; this is linked to weaker mitochondrial function and vascular aging. Raising NAD+ with nicotinamide riboside (NR) has already been shown to increase NAD+ in middle-aged/older people and to improve aortic stiffness and systolic blood pressure — exactly the stuff that starts to drift after 40. [1] [2]
So the logic is:
- Problem: 40+ → ↓NAD+ → ↓mitochondrial output, ↑inflammation, ↑arterial stiffness.
- Strategy: Give an NAD+ precursor with human data (NR), then protect/support with flavonoids and absorption helpers so the gain is sustained. [3] [4]
What does the 500 mg nicotinamide riboside actually do?
Human studies that saw the clearest vascular wins often used 1,000 mg/day NR in older adults and still called it safe, but 500 mg/day is in range to raise the NAD metabolome and point blood pressure and pulse-wave velocity in the right direction. Fmlave sits right on that 500 mg mark. Think of it as “most of the effect” rather than “maximal effect.” [1] [2] [11]
Do the add-ons really support the core?
Yes — but evidence depth isn’t uniform. NR is the high-confidence center; the others tighten inflammation, absorption, or energy so that the 40+ user actually feels something.

Ingredient-by-ingredient overview
| Ingredient (2 caps) | Main purpose | Evidence snapshot | Relevance for 40+ |
|---|---|---|---|
| NAD+ (Nicotinamide Riboside H. Malate) 500 mg | Raise NAD+, support mitochondria, improve vascular function | NR 500–1,000 mg/day ↑NAD+ and lowered SBP / carotid–femoral PWV in middle-aged & older adults. [1] [2] | Core driver; dose is conservative but in human range. |
| Vitamin D3 2,000 IU | Fill common insufficiency; immune & bone support | 2,000 IU/day is a widely used maintenance/healthy-aging dose band in older adults. [12] | Practical add-on; not the “NAD” piece but good at 40+. |
| Quercetin Phytosome 250 mg | Anti-inflammatory, immune, senomorphic; better absorption vs plain quercetin | Phytosome quercetin 500 mg/day in adults around 49 yrs improved inflammatory/immune markers; phytosome is 5–20× better absorbed. [3] [5] [6] | Good “inflammaging” brake; daily dose is half of some trials but still meaningful. |
| Resveratrol 150 mg | SIRT1/AMPK support, endothelial & metabolic protection | Most human vascular/metabolic trials used 250–500 mg/day; lower doses still pair well with piperine. [15] [16] | Supportive, especially since piperine is present. |
| Shilajit 150 mg (30:1) | Mitochondrial efficiency, anti-fatigue, adaptogenic | 200–500 mg/day standardized shilajit improved mitochondrial markers and fatigue in adults. [7] | Pairs neatly with NR to make “more NAD” → “more usable energy.” |
| Fisetin 150 mg | Senotherapeutic / anti-inflammatory | Fisetin is a top senolytic in preclinical work; human trials are using higher, often intermittent doses (e.g. NCT03675724; NCT06431932). At 150 mg/day this is “senescence-aware,” not full senolysis. [8] [9] [10] | Good daily background; manage expectations. |
| Grape Seed 100 mg; Rose Hips 100 mg; Turmeric 50 mg; Green Tea 20 mg; Acai 25 mg | Polyphenol cluster for antioxidant & vascular/joint support | Each has human data for inflammation or endothelial support; together they form a “cool the background noise” layer. | Useful for “I’m 45 and sore/busy/inflamed” scenarios. |
| Black Pepper Extract 5 mg | Increase bioavailability of curcumin, resveratrol, and other polyphenols | Piperine raised curcumin bioavailability by up to 2,000% in humans at 20 mg; even 5–10 mg is used in commercial complexes. [13] [14] [16] | Smart “glue” for an otherwise light polyphenol stack. |
So what benefits actually stack up for 40+?
Most solidly supported by human data
- Higher NAD+ / better vascular tone: NR studies in midlife/older adults showed lower SBP and pulse-wave velocity — helpful for age-related arterial stiffening. [1] [2]
- Better polyphenol uptake: piperine keeps the lighter resveratrol/turmeric doses relevant. [13] [14]
- Daily inflammation control: quercetin phytosome plus grape seed/turmeric gives a low-grade NF-κB/TNF-α brake, which is exactly what 40+ needs to stop “small” inflammation from multiplying. [3] [5] [17]
Helpful but lighter / supportive
- 150 mg resveratrol is below many trial doses but made more useful by piperine.
- 150 mg shilajit is in human range and makes the “I feel it” part more likely.
Experimental / not at clinical senolytic dose
- 150 mg fisetin daily ≠ the intermittent gram-level senolytic protocols (often paired with dasatinib or high quercetin). Good inclusion, needs honest framing. [10]
Will someone over 40 actually feel it?
- Energy / fatigue: NR restores a substrate; shilajit supports mitochondrial efficiency; together they are the most “felt” pair. [7]
- Cardiometabolic aging: if someone is sitting at “elevated” or stage-1 BP, the NR data suggest they’re likelier to see a change than someone already optimal. [1] [2]
- Inflammaging / recovery: the quercetin–turmeric–grape-seed layer, made absorbable by piperine, is exactly how several 2022–2025 reviews say to approach age-related inflammation. [5] [6] [17]
- Cellular aging: we have human proof-of-concept that senolytics can reduce senescent cells (dasatinib + quercetin) [10], and ongoing fisetin trials in older adults [8] [9], but this capsule uses a daily, smaller fisetin dose, so results will be subtler.
How does this compare with what trials actually used?
| Component | Typical trial / review dose | Fmlave NAD+ dose | What to expect |
|---|---|---|---|
| NR | 1,000 mg/day in older adults for 6–12 weeks [1] | 500 mg/day | Likely ↑NAD+, vascular benefit still plausible, just smaller. |
| Quercetin phytosome | 500 mg/day, often in 2 doses, sometimes with vit. C/bromelain [3] | 250 mg/day | Daily anti-inflammatory/immune support tier. |
| Resveratrol | 250–500 mg/day for vascular / metabolic endpoints [15] | 150 mg/day | Supportive, but piperine helps. |
| Fisetin (senolytic) | High, pulsed dosing or combo (D+Q) in human pilots [10] | 150 mg/day | More “longevity-aware polyphenol” than “full senolysis.” |
Any obvious gaps?
- No dedicated CD38 inhibitor → we’re increasing NAD+ supply, not cutting NAD+ consumption.
- Polyphenol layer is broad but not always at the strongest human dose → serious joint/metabolic use might still want standalone curcumin or higher resveratrol.
- All claims assume the user takes the full 2-capsule serving.
