The science
After 35, four cellular changes accelerate aging. Understanding them is the first step to slowing them down.
Declining NAD+ levels
NAD+ is a molecule that powers 500+ of your cellular processes. Between your 20s-40s, levels decline ~50% leading to fatigue, brain fog, and slower recovery.
Hormonal shifts
After 35, estrogen and progesterone fluctuate in ways that affect mood, sleep, metabolism, and skin. Most longevity supplements completely ignore this.
The impact: Mood swings, disrupted sleep, weight resistance
Slowing Mitochondrial Function
Your mitochondria produce energy for every cell. As they decline, so does your vitality. This explains why you feel tired even when you've slept well.
The impact: Afternoon crashes, slow recovery, reduced stamina
Accelerating Skin Aging
Collagen production slows and skin loses moisture with age. The result: fine lines, dullness, and loss of firmness that no topical can fully address.
The impact: Visible lines, loss of glow, reduced elasticity
