🫀 Atherosclerosis and NR/NMN: What Studies Say About Effects on the Vessel Wall

How NAD+ precursors affect blood vessels

Atherosclerosis is the buildup of plaques in vessels. NR (nicotinamide riboside) and NMN (nicotinamide mononucleotide) raise NAD+ and are studied for vessels. Let's look at the research.

🔬 What are NR and NMN

NR and NMN are NAD+ precursors, important for energy and cell repair. NAD+ levels drop with age, linked to vessel aging.

  • NAD+ precursors.
  • Cell repair.
  • NAD+ drops with age.
  • Studied for vessels.
Why it matters: NAD+ supports vessel endothelium function.

🫀 Atherosclerosis

Atherosclerosis is the buildup of cholesterol and plaques in artery walls, leading to narrowing and risk of heart attack and stroke.

  • Plaque buildup.
  • Artery narrowing.
  • Heart attack risk.
  • Stroke risk.
Data: inflammation and oxidative stress play key roles.

⚙️ NAD+ and vessels

NAD+ supports endothelium and vasomotor function. Restoring NAD+ through NR/NMN may improve vessel health.

  • Supports endothelium.
  • Vasomotor function.
  • NAD+ restoration.
  • Vessel health.

🐭 Animal studies

In animals, NR reduced atherosclerotic plaques and improved vessel function. Promising data, but needs human confirmation.

  • Reduced plaques.
  • Improved vessel function.
  • Promising data.
  • Needs human confirmation.
Important: animal results do not always translate to humans.

🧑 Human studies

In humans, NR/NMN are safe and raise NAD+, but clinical data on atherosclerosis effects are still limited and ongoing.

  • Raise NAD+.
  • Safe in trials.
  • Atherosclerosis data limited.
  • Studies continue.
Important: does not replace statins and cholesterol treatment.

🟠 Plaques and inflammation

NR/NMN are studied for effects on inflammation and oxidative stress — key factors in plaque development.

  • Reduce inflammation.
  • Antioxidant support.
  • Effects on plaques.
  • Promising.
Data: NAD+ restoration may reduce vessel inflammation.

💡 Practice

  • Monitor cholesterol with tests.
  • Diet and movement are the base.
  • NR/NMN as a supplement, not a replacement.
  • Do not stop statins without a doctor.
  • Consult a doctor.
Tip: with atherosclerosis, see a cardiologist.
❓ FAQ
What are NR and NMN?

NAD+ precursors supporting energy and cell repair.

Do NR/NMN help with atherosclerosis?

Promising in animals; more human research is needed.

Are NR and NMN safe?

They were well tolerated in clinical trials.

Do they replace statins?

No, they do not replace cholesterol treatment.

How do NR/NMN affect vessels?

Restore NAD+, supporting endothelium and reducing inflammation.

Do they reduce plaques?

In animals — yes; human confirmation is needed.

Who is it for?

Studied for older adults with vascular risks.

Any side effects?

Rare, mostly mild GI issues.

Diet or supplements?

Diet, movement and cholesterol control are the base.

When is a doctor needed?

With atherosclerosis, high cholesterol and statins.
