Homocysteine is an amino acid produced in the body during protein metabolism.
Normally, it is broken down with the help of vitamins like:
-Folic acid (Vitamin B9)
-Vitamin B12
-Vitamin B6
Why high homocysteine is dangerous? When homocysteine levels become high (hyperhomocysteinemia), it can:
-Damage blood vessels
-Injures the inner lining (endothelium)
-Makes arteries stiff and narrow
-Increase risk of:
-Hypertension
-Heart disease
-Stroke
-Promote inflammation & clotting
-Encourages plaque buildup (atherosclerosis)
-Increases risk of blood clots
Link between Homocysteine & Hypertension
High homocysteine:👇
-Reduces nitric oxide (less vessel relaxation)
-Causes vasoconstriction
-Leads to increased blood pressure
Eat foods rich in:👇
-Folic acid (B9)
Example like, Ugu, spinach, lettuce, Beans, lentils, vocado, Oranges
-Vitamin B12 example, Eggs, Milk & yoghurt, Fish, meat
-Vitamin B6 example like, Banana, Chicken, Potatoes
Elevated homocysteine is an independent cardiovascular risk factor, Common in patients with:
Poor diet, Vitamin deficiencies.
Supplementation with folic acid ± B12/B6 can significantly reduce levels.
“Homocysteine is a harmful substance in your blood when it becomes too high.
Eating foods rich in folic acid and vitamins helps remove it and protects your heart.
