After 50, many people begin to notice changes in their body they didn’t see before:
Cold hands and feet
Leg cramps while walking
Swelling or heaviness in the lower limbs
These can be signs of reduced circulation — a natural part of aging, but one that deserves attention.

Poor blood flow doesn’t just cause discomfort.
Over time, it can increase the risk of heart disease, stroke, and peripheral artery disease (PAD).

So what helps?
While no single vitamin is a magic fix, one stands out in both research and clinical practice: vitamin B3, also known as niacin.

But here’s what most headlines don’t tell you:
Niacin isn’t just a supplement you take casually.
It’s a potent compound with real benefits — and real risks.

Let’s explore how niacin affects blood vessels, who might benefit, and why you should never start taking it without talking to your doctor.

Because real heart health isn’t about trends.
It’s about using powerful tools wisely — under expert guidance.
