The Science of NAD+: What Every Man Over 40 Needs to Know

If you're a man in your 40s and you've noticed that your energy isn't what it used to be — that workouts take longer to recover from, that your focus wavers by midday, that sleep isn't quite as restorative — there's a biological reason. And it has a name: NAD+ decline.

What Is NAD+ and Why Does It Matter?

NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme present in every living cell. It plays a critical role in:

  • Energy production — NAD+ is essential for mitochondrial function, converting food into usable cellular energy (ATP)

  • DNA repair — it activates enzymes called sirtuins that protect and repair DNA strands

  • Cognitive function — NAD+ supports neurotransmitter signaling and protects against neurodegeneration

  • Metabolism regulation — it helps balance insulin sensitivity and inflammation

By age 40, most men have lost 30–50% of their peak NAD+ levels. By 60, it can drop even further.

The Symptoms Men Often Ignore

Most men chalk these up to "just aging":

  • Persistent fatigue despite adequate sleep

  • Difficulty concentrating or remembering details

  • Slower muscle recovery after exercise

  • Increased anxiety or low mood

  • Decreased motivation

These are red flags of NAD+ depletion — and they're not inevitable.

How NAD+ IV Therapy Works at GlowMD

At GlowMD, our NAD+ IV infusions are administered by licensed medical professionals in a calm, comfortable setting. Because NAD+ molecules are too large to absorb efficiently through the digestive tract, IV delivery is the gold standard — allowing NAD+ to reach cells directly and rapidly.

Sessions typically last 60–90 minutes, during which most clients relax, read, or simply rest. Many notice sharper mental clarity and improved energy within 24–48 hours of their first session.
