What can high homocysteine levels mean?

As vitamins B6, B12, and folate are required to break down homocysteine in the body, increased homocysteine levels may be a sign of deficiency in these vitamins. Although a raised homocysteine is a risk factor for cardiovascular disease, it is not known whether it is causative or a result of the condition.

How can I lower my homocysteine levels?

You can lower your homocysteine levels through increased vitamin B12 and folic acid intake. Always consult your doctor before making significant changes to your diet.
