Anti-Aging

Biological age reversal and cellular health

Start with the basics

Why it’s confusing

Let’s make sense of anti-aging.

A loaded phrase

"Anti-aging" is attached to everything from creams to supplements, with wildly different evidence.

Some real science exists

A few ingredients have genuine research behind them. Most of the market does not.

Scams everywhere

Serums, pills, fountain-of-youth claims — sorting real from hype takes work.

What actually holds up?

You want to know what has clinical support before spending a cent.

It’s not you — the information out there is a mess. Here’s the clear version.

Start with the basics ↓

Overview

What you need to know.

Aging is inevitable. How fast you age is not. Your cells start running low on fuel as you get older — NAD+ drops, collagen breaks down, telomeres shorten, and damage accumulates. You feel it as wrinkles, fatigue, slower recovery, and brain fog. Anti-aging research has made real progress in understanding why this happens and what can be done about it. This page covers the science, the most researched interventions, and practical steps you can take today.

Getting started

Where to start with Anti-Aging

1

Protect and Repair

Daily sunscreen, 7-9 hours of sleep, and stress management. These protect against the biggest accelerators of aging.

2

Build Strength

Resistance training 3-4x per week. Muscle mass is one of the strongest predictors of healthy aging.

3

Get Your Baseline

Comprehensive bloodwork plus consider a biological age test. Know where you stand.

Good to know

Quick tips

1

Sunscreen is the single most effective anti-aging intervention for skin. Wear it daily.

2

Resistance training preserves muscle mass, bone density, and metabolic health as you age. Start now.

3

Sleep is when your body repairs cellular damage. Chronic sleep deprivation accelerates aging measurably.

4

Manage stress — chronic cortisol elevation damages collagen, impairs immune function, and shortens telomeres.

5

Eat whole foods rich in antioxidants — colorful fruits and vegetables protect against oxidative damage.

6

Stay socially connected — loneliness is associated with accelerated biological aging in research.

FAQ

Common questions

What actually slows aging?
The interventions with the strongest research support are exercise (especially resistance training and Zone 2 cardio), adequate sleep, stress management, a nutrient-dense diet, and social connection. These are all free.
Does NAD+ therapy reverse aging?
NAD+ therapy aims to restore a molecule that declines with age. Animal studies show promising results. Human studies are growing but limited. It may support cellular energy and repair, but it is not proven to reverse aging. Not FDA-approved.
What are anti-aging peptides?
NAD+ is one of the most studied compounds for cellular energy and longevity, and collagen peptides are widely available over the counter. Talk to a licensed physician about what may be appropriate for your situation.
What is the best anti-aging supplement?
Sunscreen, sleep, and exercise are more effective than any supplement. For supplementation, creatine, omega-3, vitamin D, and collagen peptides have the most research support for age-related benefits.
Can you measure biological age?
Yes — epigenetic clocks (DNA methylation tests) can estimate biological age. Companies offer consumer tests. They are useful as a baseline but is best discussed with taken as definitive. Your physician can help interpret results.
