The Longevity Page

Live Long.
Live Well.

The goal isn't living to 95 in a body that can't move. It's healthspan: the years you're actually alive, not just breathing. And here's the exciting part: the research is clear on what extends those good years. Most of it is simpler than you think.

See What Works
01 / The Longevity Pyramid

The simple stuff works best.
And you probably already do some of it.

01

Exercise

Strongest evidence

VO2 max is one of the strongest predictors of all-cause mortality. The minimum: 150 min/week moderate or 75 min vigorous activity.

WHO Physical Activity Guidelines; Mandsager et al., JAMA 2018

02

Nutrition

Strong evidence

Mediterranean diet has the most longevity evidence. Blue Zones research found plant-forward eating in all 5 longevity hotspots worldwide.

Buettner 2016; PREDIMED trial, NEJM 2018

03

Sleep

Strong, undervalued

7 to 9 hours. Every hour under 7 increases all-cause mortality risk. The brain clears amyloid plaques during deep sleep.

Walker, Why We Sleep; Xie et al., Science 2013

04

Stress & Connection

Surprisingly strong

Harvard's 80-year study: the number one predictor of healthy aging was quality of relationships. Loneliness carries health risks comparable to smoking 15 cigarettes per day.

Harvard Study of Adult Development; Holt-Lunstad et al., PLOS Medicine 2010

05

Supplements

Mostly promising, limited data

This is where the industry makes its money. If you're not exercising, sleeping, and eating well, no supplement will compensate.

NASEM Dietary Supplements Framework, 2024

The people who live the longest don't take the most supplements. They move every day, eat real food, sleep well, and stay connected to the people they love. The best part? You can start any of this today.

Real data on longevity and perimenopause barely exists. Help us change that.

VO2 Max

Going from the bottom 25% to the top 25% of cardiorespiratory fitness reduces all-cause mortality by approximately 5x. A larger effect than quitting smoking.

Mandsager et al., JAMA Network Open 2018

Muscle Mass

Sarcopenia begins around age 30 and accelerates after 50. By 80, most adults lose 30 to 40% of muscle mass. Resistance training is the primary intervention to slow or reverse this.

Cruz-Jentoft et al., The Lancet 2019

Bone Density

Women can lose up to 20% of bone density in the 5 to 7 years following menopause. Weight-bearing exercise and resistance training are the two most effective non-pharmacological interventions.

ACSM Position Stand; NOF Guidelines

Brain Health

Regular aerobic exercise increases hippocampal volume by approximately 2%, effectively reversing 1 to 2 years of age related volume loss.

Erickson et al., PNAS 2011

What the research supports

Zone 2 Cardio

3 to 4 sessions per week, 30 to 45 minutes. Conversational pace. Builds mitochondrial density.

Iannetta et al., Sports Medicine 2020

Strength Training

2 to 3 sessions per week. Compound movements with progressive overload. Preserves muscle and bone.

ACSM Guidelines for Exercise Testing, 11th Ed.

HIIT

1 session per week. Short intervals at high intensity. Improves VO2 max efficiently.

Weston et al., BJSM 2014 meta-analysis

Balance & Mobility

Regular balance work reduces fall risk by 23% in older adults.

Sherrington et al., Cochrane Review 2019

Creatine Monohydrate

Strong human evidence

Over 500 peer reviewed studies. Improves cognitive function in aging adults, supports bone density, and may protect against neurodegeneration. One of the most studied supplements in existence.

Kreider et al., J Int Soc Sports Nutr 2017; Forbes et al., Exp Gerontol 2023

Vitamin D

Essential, widespread deficiency

42% of American adults are vitamin D deficient. Affects bone density, immune function, and mood. Deficiency is linked to increased fracture risk and all-cause mortality. Ask your doctor to test your levels.

Forrest & Stuhldreher, Nutrition Research 2011; Autier et al., Lancet Diabetes Endocrinol 2014

Omega-3 Fatty Acids

Strong cardiovascular evidence

Meta-analyses show reduced cardiovascular mortality and improved inflammatory markers. The VITAL trial (25,871 participants) found a 28% reduction in heart attacks.

Manson et al., NEJM 2019 (VITAL trial); Hu et al., JACC 2019

NAD+ Precursors (NMN, NR)

Promising, unproven in humans

They raise NAD+ levels in humans (proven). Nobody has proven this extends human lifespan. Animal data is impressive. Human longevity data doesn't exist yet.

Song et al., GeroScience 2023; Yoshino et al., Science 2021

Resveratrol

Overhyped

Generated excitement in mouse studies. Bioavailability in humans is poor. Most serious researchers have moved on from resveratrol as a longevity intervention.

Bitterman & Chung, J Physiol 2015; Visioli, Nutrients 2014

Collagen Peptides

Skin and joints, not longevity

Clinical trials show improved skin elasticity and reduced joint pain. No evidence they extend lifespan. Useful for specific purposes, not a longevity intervention.

de Miranda et al., Nutrients 2021 (meta-analysis)

Talk to your healthcare provider before starting any supplement. Individual needs vary based on health status, medications, and lab results.

Bone + Muscle

Vibration Plates

A 2022 meta-analysis found significant bone density increases with whole-body vibration. A study of 150 postmenopausal women showed reduced fall risk.

DadeMatthews et al., 2022 · Marin-Cascales et al., 2018

Skin + Pain + Hair

Red Light Therapy

Clinical evidence supports benefits for collagen production, wound healing, pain reduction, and hair growth. Multiple academic medical centers recognize photobiomodulation.

Avci et al., Seminars in Cutaneous Medicine and Surgery 2013

Recovery + Metabolism

Cold Exposure

Systematic review found cold water immersion reduces inflammation and improves mood via norepinephrine release. Activates brown adipose tissue.

Maljkovic Roy et al., BJSM 2022 · Shevchuk, Medical Hypotheses 2008

People most satisfied in their relationships at 50 were the healthiest at 80. Loneliness was as damaging as smoking or alcoholism. The people who thrived were not the ones with the most money or the best genes. They were the ones who invested in their relationships.

No supplement company can sell you this. No biohacking protocol includes it. But it may be the most important thing on this entire page.

Harvard Study of Adult Development · Holt-Lunstad et al., PLOS Medicine 2010

Blue Zones: 9 common denominators

Buettner 2016, 550 plus citations. All 5 longevity hotspots.

01

Move naturally (daily movement, not gym sessions)

02

Know your purpose (Okinawans call it 'ikigai')

03

Downshift (daily routines to manage stress)

04

80% Rule (stop eating when 80% full)

05

Plant slant (beans are the dietary foundation)

06

Belong (most centenarians belong to a faith community)

07

Loved ones first (keep aging parents nearby, invest in children)

08

Right tribe (social circles that reinforce healthy behaviors)

We rejected 4 popular products. Here's why.

Every product we recommend has to pass our evidence standard. These didn't.

The bottom line.

The people who live the longest don't take the most supplements. They move every day, eat real food, sleep well, and stay connected to the people they love. Harvard studied this for 80 years. The answer was never a pill. It was always the simple stuff.

Women who begin strength training in their 60s still gain muscle. Women who deepen friendships in their 50s still see health benefits. It's never too late. And honestly? For most of us, it's just getting started.
