Even if you eat right, exercise, and get sleep — there’s a biological reason fatigue hits harder after midlife.
The Frustration of “Doing Everything Right”
You eat a balanced diet. You get your workouts in. You try to get quality sleep. And yet — you still feel exhausted. For many men over 50, this isn’t about willpower or routine. It’s about what’s happening inside your cells.
The NAD+ Decline After 50
Research shows that after age 40, NAD+ (nicotinamide adenine dinucleotide) levels decline sharply — in fact, by 50 they can be cut in half. NAD+ is a coenzyme that fuels mitochondrial energy, cellular repair, and cognitive performance. Without it, your body feels like it’s running on empty no matter how disciplined your lifestyle is.
How NAD+ Impacts Energy, Recovery, and Clarity
- Energy: Less NAD+ means weaker mitochondrial function — the engines of your cells slow down.
- Recovery: Soreness lingers longer because repair cycles are less efficient.
- Cognition: Declines in NAD+ are linked with brain fog, memory lapses, and decreased focus.
The Problem With Generic Supplements
Most supplements on the market are packed with cheap fillers like rice powder and underdosed active ingredients. They may look good on a label, but they don’t address the cellular realities of aging. For men over 50, that’s not just disappointing — it’s a waste of time.
The GrayLabs Solution
At GrayLabs, we created Core NAD+™ — a pharmaceutical-grade formula designed to restore cellular energy. Combined with Male+™, it targets testosterone decline, recovery, and resilience. No fillers. No shortcuts. Just precision science built for performance-driven aging.
