How does homocysteine affect health?

Homocysteine is an amino acid that, when elevated in the bloodstream, can adversely affect health. High levels of homocysteine have been associated with several health issues, including:

1. Cardiovascular Disease: Elevated homocysteine levels can damage blood vessels and promote atherosclerosis, increasing the risk of heart attacks and strokes.

2. Cognitive Decline: Studies suggest a link between high homocysteine and neurodegenerative diseases, such as Alzheimer’s. It may contribute to cognitive decline and memory impairment.

3. Blood Clotting: Increased homocysteine can enhance the risk of thrombosis, leading to abnormal blood clot formation.

4. Bone Health: High homocysteine levels may adversely affect bone density, potentially increasing the risk of fractures and osteoporosis.

Maintaining optimal homocysteine levels is important for overall health, and addressing deficiencies in nutrients such as vitamin B12, B6, and folate can help regulate these levels and mitigate potential health risks. These insights align with discussions from experts like Dr. Peter Attia, who emphasize the importance of managing homocysteine for longevity and cardiovascular health.
