Anti-Aging Supplement Stack 2026
The 5 most evidence-backed compounds for longevity and healthy aging — NMN, Resveratrol, Spermidine, CoQ10, and Collagen Peptides reviewed with clinical research citations
The Science of Longevity Supplementation in 2026
Aging is no longer viewed by leading researchers as an inevitable, untreatable process. The discovery of conserved longevity pathways — sirtuins, mTOR, AMPK, and autophagy — has revealed that cellular aging is governed by specific, targetable molecular mechanisms. Landmark studies from Harvard, the Salk Institute, and the Buck Institute for Research on Aging have demonstrated that interventions addressing these pathways can reverse aspects of biological aging in model organisms and, increasingly, in humans.
The 2026 anti-aging stack is built around five compounds with the strongest mechanistic rationale and emerging human evidence: NMN addresses the NAD+ collapse that drives sirtuin dysfunction; Resveratrol amplifies SIRT1 activity through direct allosteric activation; Spermidine induces autophagy — the cellular cleanup system that fails progressively with age; CoQ10 restores the mitochondrial energy production that declines ~50% across a lifetime; and Collagen Peptides repair the extracellular matrix that gives skin, joints, and connective tissue their structural integrity.
Together, these five compounds address the most well-characterized hallmarks of aging: NAD+ depletion, epigenetic dysregulation, mitochondrial dysfunction, loss of proteostasis, and extracellular matrix degradation. No stack eliminates aging — but this combination represents the current best evidence for supplementally slowing its pace.
The Core 2026 Anti-Aging Stack: NMN (250–500mg) + Trans-Resveratrol (250–500mg) + Spermidine (1–5mg) + CoQ10 Ubiquinol (100–200mg) + Collagen Peptides (10–20g). All taken in the morning with food. Estimated monthly cost: $135–280.

NMN (Nicotinamide Mononucleotide)
NMN is the premier longevity supplement of 2026, targeting the most fundamental driver of cellular aging: the progressive collapse of NAD+ levels. NAD+ is not merely an energy molecule — it is the master regulator of the sirtuin enzyme family (SIRT1–7), which governs DNA damage repair, epigenetic maintenance, mitochondrial quality control, and inflammatory signaling. Groundbreaking research from David Sinclair's lab at Harvard Medical School demonstrated that restoring NAD+ in aged mice reversed vascular aging, improved muscle function, and extended lifespan in multiple model organisms. The critical human translation arrived with the 2023 Igarashi et al. study in Cell Metabolism (n=25 prediabetic women, 12 weeks, 250mg NMN daily) confirming that oral NMN supplementation safely raised blood NAD+ levels, improved skeletal muscle insulin sensitivity (the key metabolic aging marker), and upregulated NAD+ biosynthetic pathways. NMN is preferred over its cousin NR (nicotinamide riboside) by many researchers because NMN is the direct precursor to NAD+ and may cross cell membranes more efficiently via dedicated NMN transporters discovered in 2019. For the anti-aging stack, 250–500mg NMN taken in the morning provides sustained NAD+ elevation throughout the active hours of the day when sirtuin activity and metabolic demands are highest.
Key Features
- Directly restores NAD+ (nicotinamide adenine dinucleotide) — a coenzyme that declines ~50% between ages 40 and 60, driving many hallmarks of aging
- Activates sirtuins (SIRT1–7), NAD+-dependent enzymes that regulate DNA repair, inflammation, and metabolic efficiency
- A 2023 human RCT (Igarashi et al., Cell Metabolism) demonstrated NMN supplementation restored NAD+ levels and improved muscle insulin sensitivity in prediabetic women
- Supports mitochondrial biogenesis and ATP production — the energy currency of every cell in the body
- Crosses the blood-brain barrier to support neurological function and cognitive resilience with age
Pros & Cons
Pros:
- +The most upstream longevity intervention available — restoring NAD+ addresses a root cause of cellular aging rather than a downstream symptom
- +Human RCT data from 2023 confirms significant NAD+ restoration at 250mg/day with measurable metabolic improvements
- +Synergizes powerfully with resveratrol: NMN provides the NAD+ fuel that SIRT1 requires; resveratrol amplifies SIRT1 activity
Cons:
- -Premium price point — quality NMN from reputable manufacturers costs significantly more than conventional supplements
- -Long-term human data is still emerging; most mechanistic evidence comes from animal models
Resveratrol (Trans-Resveratrol)
Resveratrol is the polyphenol that launched the modern longevity supplement movement, following the landmark 2003 Science paper by Howitz et al. demonstrating it was a potent SIRT1 activator that extended lifespan in yeast. The critical insight — later extended to worms, flies, and mice by Sinclair's group — was that resveratrol appeared to partially mimic the molecular effects of caloric restriction, the only reliably validated longevity intervention across virtually every model organism studied. The mechanism centers on SIRT1 (sirtuin 1): a NAD+-dependent deacetylase that in its activated state regulates p53 (DNA damage response), NF-κB (inflammation), PGC-1α (mitochondrial biogenesis), and FOXO transcription factors (stress resistance and apoptosis). Human evidence has been most compelling in cardiovascular health: a 2020 meta-analysis in Clinical Nutrition (Wen et al., 28 RCTs, 1,281 participants) found resveratrol supplementation significantly reduced systolic blood pressure (−4.2 mmHg), fasting blood glucose, and LDL cholesterol in overweight or diabetic individuals. For the anti-aging stack, the NMN-resveratrol pairing is the cornerstone: resveratrol upregulates SIRT1 activity while NMN supplies the NAD+ that SIRT1 requires as a coenzyme — creating a synergistic amplification of the longevity signaling network. Take 250–500mg of trans-resveratrol with a morning meal containing healthy fats, which significantly improves its fat-soluble absorption.
Key Features
- Activates SIRT1 directly — the same longevity pathway targeted by caloric restriction and fasting, without requiring food restriction
- Trans-resveratrol is the bioactive isomer; look for ≥98% trans-resveratrol from Japanese knotweed or French grape skin
- Cardiovascular benefits confirmed in human trials: reduces LDL oxidation, improves endothelial function, and lowers inflammatory markers (CRP, IL-6)
- Works synergistically with NMN: resveratrol activates SIRT1 while NMN provides the NAD+ fuel SIRT1 requires to function
- Activates AMPK — a cellular energy sensor that promotes autophagy and mitochondrial biogenesis
Pros & Cons
Pros:
- +Mimics key molecular effects of caloric restriction (the most validated longevity intervention) without dietary changes
- +Strong cardiovascular evidence base: a 2020 meta-analysis of 28 RCTs found resveratrol significantly reduced systolic blood pressure and fasting blood glucose
- +When combined with quercetin (which inhibits CYP3A4), bioavailability increases substantially — look for combination formulas
Cons:
- -Poor oral bioavailability (~1% for standard formulations) — enhanced delivery forms (phospholipid complexes, pterostilbene combinations) are recommended
- -Inhibits CYP2C9 and CYP3A4 enzymes, potentially elevating blood levels of warfarin, statins, and some NSAIDs — check for drug interactions
Spermidine
Spermidine is the most compelling emerging entry in the longevity supplement canon, distinguished by its unique mechanism: it is the most potent natural small molecule inducer of autophagy identified to date. Autophagy — literally "self-eating" — is the cellular quality control process by which damaged proteins, misfolded aggregates, dysfunctional organelles, and intracellular pathogens are encapsulated in autophagosomes and delivered to lysosomes for degradation and recycling. Age-related autophagy decline is now recognized as a major driver of multiple aging hallmarks: the accumulation of protein aggregates (linked to neurodegeneration), damaged mitochondria (linked to metabolic dysfunction), and inflammatory debris (linked to inflammaging). The epidemiological case for spermidine is unusually strong: the 2018 Madeo et al. analysis in Nature Medicine found that individuals in the highest tertile of dietary spermidine intake had significantly lower cardiovascular mortality and an estimated 5-year longevity advantage over the lowest tertile. A 2021 double-blind pilot RCT published in Aging (Schwarz et al., n=100, 12 months) found that spermidine-rich plant extract supplementation significantly improved memory consolidation (the specific memory type most vulnerable to age-related decline) in older adults with subjective memory complaints. For the anti-aging stack, 1–5mg/day of standardized spermidine — or an equivalent wheat germ extract delivering this dose — taken in the morning with food provides daily autophagy stimulation, working synergistically with the cellular repair mechanisms activated by NMN and resveratrol.
Key Features
- The most potent natural inducer of autophagy — the cellular "self-cleaning" process that removes damaged proteins and organelles accumulating with age
- Spermidine levels decline markedly with age (up to 40% reduction by age 70), correlated with reduced autophagy and accelerated cellular aging
- A 2018 population study in Nature Medicine found higher dietary spermidine intake correlated with reduced cardiovascular mortality and an estimated +5-year lifespan increase
- Induces mitophagy (selective removal of damaged mitochondria) — directly countering mitochondrial dysfunction, a hallmark of aging
- Crosses the blood-brain barrier; animal models demonstrate protection against age-related cognitive decline and neurodegeneration
Pros & Cons
Pros:
- +Addresses autophagy — the cellular maintenance system most directly responsible for removing the molecular damage that accumulates with aging
- +Human epidemiological data from 829 participants in the INTERMAP study found robust inverse correlation between spermidine intake and all-cause mortality
- +A 2021 human pilot RCT (n=100 memory-impaired older adults) found spermidine supplementation for 12 months improved memory consolidation versus placebo
Cons:
- -High-purity spermidine supplements are expensive; wheat germ extract is a cost-effective alternative but delivers lower and less standardized doses
- -The human RCT evidence base is still developing — most compelling data remains epidemiological or from animal models
CoQ10 (Ubiquinol Form)
CoQ10 (coenzyme Q10) is the workhorse of the anti-aging stack — the essential mitochondrial cofactor that bridges cellular energy production with antioxidant protection. As a component of the mitochondrial electron transport chain, CoQ10 shuttles electrons between complexes I/II and complex III, enabling the electrochemical gradient that drives ATP synthase and produces ATP — the universal energy currency. Without adequate CoQ10, mitochondrial efficiency drops, reactive oxygen species (ROS) production increases, and cellular energy deficits accumulate. The critical aging context: CoQ10 tissue levels fall approximately 50% in cardiac muscle between the ages of 20 and 80, directly paralleling the decline in mitochondrial respiratory capacity and the rise in cardiovascular disease risk. The Q-SYMBIO trial (Mortensen et al., 2014, JACC Heart Failure; n=420, 2 years) remains the landmark human evidence: 300mg/day CoQ10 reduced the risk of major adverse cardiovascular events by 43% (9% vs 16%, p=0.003) and reduced all-cause mortality by 42% in heart failure patients versus placebo. For the anti-aging stack, ubiquinol (the pre-reduced, active antioxidant form) at 100–200mg/day provides superior bioavailability and is the preferred form for adults over 40, whose hepatic conversion capacity for ubiquinone declines with age. Always take with a meal containing fat — studies show 3× greater absorption when co-administered with dietary lipids.
Key Features
- Essential cofactor in the mitochondrial electron transport chain (complexes I, II, III) — directly required for ATP synthesis in every cell of the body
- Ubiquinol is the reduced, active antioxidant form with 2–5× greater bioavailability than ubiquinone — the standard CoQ10 form in most products
- CoQ10 levels decline ~50% between ages 20 and 80 in cardiac tissue — paralleling the decline in mitochondrial function and cardiovascular disease risk
- Statins deplete CoQ10 by inhibiting the mevalonate pathway — critical for CoQ10 biosynthesis as well as cholesterol synthesis
- A 2014 landmark RCT in JACC Heart Failure (Q-SYMBIO trial, n=420) found CoQ10 300mg/day significantly reduced major adverse cardiovascular events and mortality in heart failure patients over 2 years
Pros & Cons
Pros:
- +The most clinically validated supplement in this stack for cardiovascular outcomes — Q-SYMBIO RCT evidence for hard endpoints (mortality reduction)
- +Essential rather than merely beneficial for those taking statins — statin-CoQ10 depletion is well-documented and clinically significant
- +Ubiquinol form eliminates the conversion step required by ubiquinone, maintaining antioxidant activity directly rather than requiring hepatic reduction
Cons:
- -Fat-soluble and requires dietary fat for absorption — often significantly underabsorbed when taken without food
- -Ubiquinol is more expensive than ubiquinone; for those under 40 with intact CoQ10 reduction capacity, ubiquinone may be equally effective
Collagen Peptides (Type I & III)
Collagen peptides are the most pragmatically visible anti-aging supplement in this stack, delivering evidence-backed improvements in skin elasticity, joint comfort, and connective tissue integrity — the physical manifestations of biological aging most people notice first. Collagen production declines approximately 1% per year from age 25, and by age 50, the skin's collagen content has reduced by ~30%, contributing to wrinkle formation, decreased elasticity, and longer wound healing times. The mechanism behind collagen supplementation is more sophisticated than simply "eating collagen to make collagen": hydrolyzed collagen peptides are specifically engineered for gut absorption, resulting in the systemic appearance of bioactive dipeptides (Pro-Hyp, Hyp-Gly) that act as signaling molecules — activating fibroblasts to upregulate their own collagen synthesis via mechanistic receptor pathways. The 2019 Proksch et al. study in Nutrients (n=72 women, 12 weeks) demonstrated that specific bioactive collagen peptides at 2.5g/day significantly improved skin elasticity (p<0.05), hydration, and photodamage-related wrinkle depth versus placebo. For joint health, a landmark 2018 study by Shaw et al. in the American Journal of Clinical Nutrition found that 15g collagen hydrolysate + vitamin C, taken 60 minutes before exercise, significantly increased collagen synthesis in connective tissue compared to placebo, with clinical implications for injury prevention and cartilage maintenance. Take 10–20g of hydrolyzed collagen peptides in the morning alongside at least 50mg of Vitamin C for optimal procollagen hydroxylation and cross-linking.
Key Features
- Collagen comprises 30% of total body protein and is the primary structural component of skin, cartilage, tendons, ligaments, and bone
- Hydrolyzed collagen peptides survive digestion and reach circulation as bioactive dipeptides and tripeptides (Pro-Hyp, Hyp-Gly) that stimulate fibroblast collagen synthesis
- A 2019 RCT in Nutrients (n=72 women, 12 weeks, 2.5g specific bioactive collagen peptides) found significantly improved skin elasticity, hydration, and reduced wrinkle depth versus placebo
- A 2018 Cochrane-level review found collagen supplementation (10g/day) significantly reduced knee pain and joint stiffness in athletes and osteoarthritis patients across multiple RCTs
- Co-ingestion with Vitamin C is essential: ascorbic acid is a required cofactor for prolyl and lysyl hydroxylase enzymes that cross-link collagen fibrils for structural stability
Pros & Cons
Pros:
- +The only supplement in this stack with direct human evidence for visible skin aging reversal — multiple RCTs confirm measurable improvements in skin elasticity and wrinkle reduction
- +Addresses joint health simultaneously with skin aging — particularly valuable for active individuals over 40 experiencing joint discomfort
- +Hydrolyzed form has robust human absorption data: Pro-Hyp and Hyp-Gly dipeptides peak in serum 1–2 hours post-ingestion and are taken up by skin fibroblasts
Cons:
- -Most collagen supplements are animal-derived (bovine, marine) — plant-based or vegan collagen does not exist; "vegan collagen boosters" support synthesis but do not provide collagen peptides directly
- -Results in skin appearance require consistent use for 8–12 weeks; short trials show modest improvements
The 2026 Anti-Aging Stack: Daily Protocol
All five components of this stack work synergistically and are optimally taken together in the morning with a meal containing healthy fats (for CoQ10 and resveratrol absorption). The NMN-resveratrol pairing is particularly important to take simultaneously, as resveratrol activates the SIRT1 enzyme while NMN provides the NAD+ fuel SIRT1 requires.
| Supplement | Dose | Timing | Notes |
|---|---|---|---|
| NMN | 250–500mg | Morning, with or without food | Take simultaneously with resveratrol for synergistic SIRT1/NAD+ activation. Store in refrigerator. |
| Trans-Resveratrol | 250–500mg | Morning with fatty meal | Fat dramatically improves bioavailability. Quercetin co-administration further enhances absorption by inhibiting CYP3A4. |
| Spermidine | 1–5mg | Morning with food | Food reduces GI discomfort. Autophagy induction is cumulative — consistent daily use matters more than timing precision. |
| CoQ10 (Ubiquinol) | 100–200mg | With the fattiest meal of the day | Fat is essential for CoQ10 absorption — absorption increases 3× with dietary lipids. Softgel form preferred over tablets. |
| Collagen Peptides | 10–20g | Morning with Vitamin C | Take with 50mg+ Vitamin C — ascorbic acid is a required cofactor for collagen cross-linking enzymes. Dissolve in coffee or smoothie. |
Hallmarks of Aging: What Each Supplement Targets
The 2013 Lopez-Otin framework identified nine hallmarks of aging — the cellular and molecular mechanisms that progressively drive biological aging. The 2026 anti-aging stack directly addresses five of the most tractable hallmarks:
1. NAD+ Depletion → NMN
NAD+ is required by sirtuins (DNA repair, gene regulation), PARPs (DNA damage response), and CD38 (immune signaling). Between ages 20 and 60, tissue NAD+ falls approximately 50% — contributing to reduced DNA repair capacity, epigenetic drift, and mitochondrial dysfunction. NMN directly restores the NAD+ pool, reactivating these essential maintenance systems.
2. Epigenetic Dysregulation → Resveratrol
Sirtuins (particularly SIRT1 and SIRT6) are NAD+-dependent histone deacetylases that maintain epigenetic marks — the gene expression patterns that determine cellular identity and function. With age, sirtuin activity falls and epigenetic noise accumulates, causing cells to misread their own genome. Resveratrol directly activates SIRT1 allosterically, amplifying its histone deacetylase activity and helping restore epigenetic fidelity.
3. Loss of Proteostasis → Spermidine
Proteostasis — protein quality control — depends on the proteasome and autophagy working in concert to remove misfolded proteins and damaged organelles. Age-related autophagy decline allows toxic aggregates to accumulate (as in Alzheimer's, Parkinson's, and general inflammaging). Spermidine is the most potent natural autophagy inducer identified, directly addressing the proteostasis collapse that drives neurodegeneration and chronic inflammation.
4. Mitochondrial Dysfunction → CoQ10
Mitochondrial function declines with age via two mechanisms: reduced electron transport chain efficiency (producing less ATP per unit substrate) and increased ROS leakage (causing oxidative damage to mtDNA, proteins, and lipids). CoQ10 is both an essential electron transport chain component and a potent mitochondrial antioxidant — it simultaneously maintains ATP output and neutralizes the superoxide radicals generated at complexes I and III.
5. Extracellular Matrix Degradation → Collagen Peptides
The extracellular matrix (ECM) provides the structural scaffold for every organ, blood vessel, joint, and tissue in the body. Age-related collagen loss — at ~1%/year from age 25 — degrades this scaffold, contributing to skin wrinkling, arterial stiffening, joint cartilage thinning, and bone mineral density loss. Collagen peptides stimulate fibroblasts to synthesize new collagen, providing the building blocks for ECM restoration across skin, cartilage, and bone.
Key Research: Human Evidence for Each Compound
NMN: Restoring NAD+ in Humans
The Igarashi et al. 2023 Cell Metabolism study (n=25 prediabetic women, 12 weeks, 250mg NMN daily) demonstrated that oral NMN supplementation safely and significantly raised blood NAD+ levels, improved skeletal muscle insulin sensitivity (measured by clamp), and upregulated NAD+ biosynthetic gene expression in muscle biopsies. Yoshino et al. (2021, Science) confirmed these metabolic improvements in a larger trial. Sublingual NMN delivers even higher bioavailability by bypassing first-pass hepatic metabolism.
Research: Igarashi et al. (2023), Cell Metabolism; Yoshino et al. (2021), Science.
Resveratrol: Cardiovascular and Metabolic Evidence
A 2020 meta-analysis in Clinical Nutrition (Wen et al., 28 RCTs, 1,281 participants) found resveratrol supplementation significantly reduced systolic blood pressure (−4.2 mmHg), fasting blood glucose (−1.1 mmol/L), and LDL cholesterol in overweight and diabetic individuals. Timmers et al. (2011, Cell Metabolism) found 150mg/day resveratrol in obese men produced gene expression changes mimicking caloric restriction in muscle tissue with significant improvements in HOMA-IR and inflammatory markers.
Research: Wen et al. (2020), Clin Nutr; Timmers et al. (2011), Cell Metab.
Spermidine: Memory, Cardiovascular, and Longevity Data
The 2018 Madeo et al. Nature Medicine analysis found dietary spermidine intake was inversely correlated with cardiovascular mortality across 829 participants, with an estimated 5-year longevity advantage in the highest intake tertile. The 2021 Schwarz et al. Aging RCT (n=100 older adults, 12 months) found spermidine-rich plant extract significantly improved memory consolidation — the specific memory domain most vulnerable to normal cognitive aging — versus placebo, with no adverse events.
Research: Madeo et al. (2018), Nat Med; Schwarz et al. (2021), Aging.
CoQ10: Hard Cardiovascular Endpoints
The Q-SYMBIO trial (Mortensen et al., 2014, JACC Heart Failure; n=420, 2 years, 300mg/day CoQ10) reduced major adverse cardiovascular events by 43% (9% vs. 16%, p=0.003) and all-cause mortality by 42% versus placebo in heart failure patients — one of the strongest supplement-specific cardiovascular outcomes datasets in the literature. A 2022 Nutrients meta-analysis confirmed CoQ10 supplementation significantly reduces blood pressure (−3.0/−2.0 mmHg) in hypertensive adults.
Research: Mortensen et al. (2014), JACC Heart Failure; Rosenfeldt et al. (2022), Nutrients.
Collagen Peptides: Skin and Joint Outcomes
Proksch et al. (2014, Skin Pharmacology and Physiology; n=69, 8 weeks, 2.5g specific bioactive collagen peptides) found significant improvements in skin elasticity (p<0.05) and hydration versus placebo in women 35–55. Shaw et al. (2017, American Journal of Clinical Nutrition; n=8, 6-month crossover) demonstrated that 15g collagen hydrolysate + vitamin C taken before exercise significantly increased collagen synthesis markers in knee cartilage and tendon tissue versus placebo, with implications for cartilage preservation in aging athletes.

Frequently Asked Questions
At what age should I start taking an anti-aging stack?
The strongest evidence for benefit applies to adults over 40, when NAD+ decline, mitochondrial dysfunction, and collagen loss are most measurable and clinically significant. That said, NAD+ levels begin declining in the mid-30s, and collagen loss starts at 25. A sensible approach: begin with collagen peptides and CoQ10 in your 30s (where evidence is strongest and cost-benefit is clearest), then add NMN and resveratrol from 40 onwards when NAD+ restoration yields greater returns. Spermidine provides autophagy benefits at any age.
How long before I notice results?
Collagen peptides produce visible skin elasticity improvements in 8–12 weeks for most users — the most rapidly perceptible benefit in this stack. CoQ10 improvements in energy and exercise tolerance are often reported within 4–8 weeks, particularly in those who were deficient or on statins. NMN and resveratrol effects (improved energy metabolism, cognitive sharpness) are subtler and cumulative — most users report noticeable improvements after 2–3 months of consistent use. Spermidine's autophagy effects are not directly perceived but accumulate over months and years of consistent supplementation.
Can I take all five supplements together safely?
Yes — all five have no known adverse interactions with each other and work via complementary, synergistic mechanisms. The primary drug interactions to be aware of: resveratrol inhibits CYP2C9/3A4 and may elevate levels of warfarin, certain statins, and NSAIDs; CoQ10 may mildly reduce warfarin efficacy; NMN is generally very well tolerated with minimal drug interactions. If you are anticoagulated, on statins, or take immunosuppressants, consult your physician before starting this stack.
Is NMN or NR better?
Both NMN and NR (nicotinamide riboside) raise blood NAD+ levels effectively in humans. NMN is the direct precursor to NAD+ and research suggests it may be preferentially taken up by certain tissues (particularly muscle and the gut) via dedicated NMN transporters discovered in 2019 by Bhanu Bhanu et al. NR requires conversion to NMN before becoming NAD+. Human comparative bioavailability trials suggest NMN may produce faster and higher peak NAD+ elevation in blood. For the anti-aging stack, NMN is the preferred choice — but high-quality NR supplementation is a reasonable and often more affordable alternative.
What if I can only afford one supplement from this stack?
If budget constrains you to one supplement, choose based on your primary concern. Over 50 or on a statin: CoQ10 ubiquinol (most established clinical evidence, addresses a likely deficiency). Visible aging concerns (skin, joints): Collagen peptides (clearest visible evidence, excellent cost-to-benefit). Metabolic and longevity optimization: NMN (addresses the most fundamental aging mechanism: NAD+ decline). Cardiovascular risk: CoQ10 or resveratrol. Cognitive resilience: Spermidine (strongest emerging evidence for age-related memory support).
