Vitamin B12 Deficiency Linked to Increased Heart Attack Risk
Imagine your body has tiny helpers that keep your blood vessels healthy.
One of these helpers is vitamin B12.
If you don't have enough B12, it's like not having enough helpers.
This can lead to a buildup of a harmful substance called homocysteine in your blood.
High homocysteine can damage your blood vessels, making them stiff and more likely to get blocked.
When blood vessels get damaged, it can cause high blood pressure and raise the risk of a heart attack.
You can get B12 from foods like meat and milk.
If you don't eat these, or if your body has trouble absorbing B12, you might need a supplement to keep your heart healthy.
Vitamin B12 deficiency is associated with increased blood pressure.
Low B12 levels can elevate homocysteine, a risk factor for heart problems.
High homocysteine damages blood vessels and increases plaque buildup.
B12 deficiency can impair nerve function, affecting heart rate and blood pressure.
Regular B12 level checks are important for heart health.
