Anti-aging supplements are gaining popularity for their potential to slow cellular aging. Have you heard of NAD⁺ or sirtuins? These buzz-words pop up because, as we age, our cells lose energy and accumulate damage. Compounds like NMN, resveratrol and fisetin target these pathways and may help us fight cellular aging at the source.
Evidence is still emerging. Always consult a qualified healthcare professional before starting any supplement.
Why Scientists Are Obsessed With Cellular Aging (NAD⁺, Sirtuins, Senolytics)
| Pathway | What It Does | Why It Matters |
|---|---|---|
| NAD⁺ | Acts as the cell’s “battery pack.” NAD⁺ levels plunge with age, starving mitochondria of fuel. | Low NAD⁺ is linked to sluggish energy, weaker muscles and higher metabolic-disease risk. |
| Sirtuins | DNA-maintenance proteins switched on by NAD⁺. They calm inflammation and bolster stress-resilience. | Active sirtuins correlate with longer lifespan, better blood-sugar control and brain protection. |
| Senolytics | Compounds that clear out “zombie” (senescent) cells that leak toxins into nearby tissue. | Removing senescent cells reduces chronic inflammation and may restore organ function, potentially slowing age-related decline. |
NMN at a Glance—Research Doses, Pros & Cons
- What it is: A Vitamin B3 derivative that raises intracellular NAD⁺.
- Animal research: Improves endurance, insulin sensitivity and some cognitive metrics.
- Human research: Early-stage, small trials only; results are still preliminary.
- Doses used in studies: 250 – 500 mg per day.
- Downsides: High cost, oral absorption under debate, no FDA-approved health claims.
Food sources? Broccoli, cabbage and cucumbers contain trace amounts—too low to match study levels.
Resveratrol—Human Evidence & Absorption Hacks
- What it is: Polyphenol found in red-grape skins, red wine and peanuts.
- Reported benefits: Healthier blood vessels, lower inflammation, possible sirtuin activation—yet no proven life-extension in humans.
- Doses used in studies: 100 – 500 mg per day.
- Absorption tip: Take with healthy fats (e.g., olive oil, walnuts) or choose a liposomal capsule to boost bioavailability.
Fisetin—The Promising Senolytic
- What it is: Flavonoid abundant in strawberries and apples that helps eliminate senescent cells.
- Animal research: Extends lifespan, improves mobility and offers neuro-protection in mouse models.
- Supplement ranges studied: 100 – 500 mg per day (no consensus human dose yet).
- Top food source: Strawberries—plus apples, onions, persimmons and cucumbers.
Safety First—Can You Combine Them?
Before starting any anti-aging supplements, consult your doctor.
- No major medical society currently endorses NMN, resveratrol or fisetin for longevity.
- Evidence in humans is preliminary; discuss any supplement plan with a healthcare professional.
- The NMN + resveratrol “stack” appears in research because together they raise tissue NAD⁺ levels, but human safety data are limited.
- Who should avoid or exercise caution:
- Pregnant or breastfeeding individuals
- People on anticoagulants, diabetes or chemotherapy medications
- Those with chronic liver or kidney disease
- Anyone scheduled for surgery in the next 2 weeks
Quick-Action Checklist
- Eat the rainbow: More strawberries, red grapes, broccoli and other colorful produce.
- Lifestyle trumps pills: Consistent exercise, restorative sleep and stress management beat any supplement stack.
- Supplements? Interesting—but best viewed as potential bonuses while focusing on proven anti-aging supplements strategies like diet and exercise.

Key Takeaway—Your Best Anti-Aging Strategy
A diverse, whole-food diet plus movement, stress reduction and quality rest deliver proven, measurable benefits for heart, brain and overall longevity. NMN, resveratrol and fisetin are exciting research topics, yet still experimental for human health—think of them as optional extras, not foundations. Meanwhile, a consistent routine with proven anti-aging supplements, combined with healthy habits, can maximize your potential for graceful aging and long-term well-being.
Prioritize a whole-food diet and regular exercise as your foundation, and consider anti-aging supplements as optional additions to support cellular health.
