| Vitamin B3 May Up Heart Attack and Stroke Risk |
Vitamin B3, also known as niacin, plays a
crucial role in keeping our bodies healthy. It helps convert food into energy,
supports proper digestion and nervous system function, and maintains healthy
skin. However, recent research suggests that exceeding recommended levels of
vitamin B3, particularly through supplements, may be linked to an increased
risk of heart attacks and strokes.
The Two Faces of Vitamin
B3:
There are two main forms
of vitamin B3:
Nicotinic acid: This form is commonly used in
prescription medications to lower cholesterol and triglycerides. However, it
comes with potentially serious side effects, including flushing, nausea, and
liver damage.
Niacinamide: This form is gentler and found in
various food sources like meat, fish, poultry, and legumes. It doesn't
typically cause flushing but doesn't seem to offer the same
cholesterol-lowering benefits as nicotinic acid.
The Concern: High Blood
Levels and Inflammation
Studies have shown an association between high
levels of circulating vitamin B3 (mainly from supplements) and an increased
risk of heart attacks and strokes. This risk seems to be more pronounced in
individuals with pre-existing health conditions like diabetes, high blood pressure,
or existing heart disease.
The exact mechanism
behind this link is still under investigation, but it's thought that high
levels of B3 might:
Increase inflammation: Chronic inflammation
plays a role in the development of various cardiovascular diseases.
Impair blood vessel function: B3 might
contribute to the stiffening and narrowing of blood vessels, making them more
prone to blockages.
Interfere with other medications: If you're on
medications for heart health, taking high doses of B3 supplements could create
unwanted interactions.
What does this mean for
you?
It's important to remember that most people get
enough vitamin B3 from their diet. The daily recommended amount for adults is
around 16mg for men and 14mg for women. This can be easily achieved through a
balanced diet rich in meat, fish, poultry, legumes, and whole grains.
Here's what you should
do:
Avoid exceeding the recommended B3 intake. Don't
take high-dose B3 supplements without consulting your doctor, especially if you
have any underlying health conditions.
Get your B3 from food: Prioritize dietary
sources of B3. They provide other beneficial nutrients along with the vitamin.
Talk to your doctor. If you're considering
taking B3 supplements, discuss it with your doctor first. They can assess your
individual needs and potential risks.
This research is ongoing, and more studies are
needed to fully understand the link between B3 and cardiovascular risks.

By staying informed and making informed choices,
you can ensure you're getting the benefits of vitamin B3 without putting your
heart health at risk.
