Vitamins, Vascular Health and Disease

Area of Science:

• Biochemistry
• Vascular Biology
• Nutritional Science

Background:

• Endothelial cells are vital for vascular tone, blood fluidity, and integrity.
• Endothelial dysfunction, linked to poor vitamin absorption, contributes to cardiovascular and other vascular diseases.
• B-group vitamins, C, D, and E are essential for endothelial function and mitigating vascular damage.

Purpose of the Study:

• To review the role of B-group vitamins, especially folate, in maintaining vascular health.
• To discuss dietary sources and therapeutic forms of folate, including L-methylfolate and levoleucovorin.
• To highlight interventions for preventing hyperhomocysteinemia and related vascular disorders.

Main Methods:

• Literature review of the role of vitamins in endothelial function.
• Analysis of dietary sources and metabolic pathways of folate.
• Examination of therapeutic strategies for vascular health.

Main Results:

• Folate (vitamin B9) is central to one-carbon metabolism, converting homocysteine to methionine, thus reducing vascular toxicity.
• Vitamins B12, B6, C, D, and E also support endothelial function through various mechanisms.
• Active folate forms like L-methylfolate bypass metabolic conversion issues.

Conclusions:

• Targeted vitamin supplementation and dietary improvements are key to restoring endothelial homeostasis.
• Interventions can slow disease progression in disorders linked to endothelial dysfunction.
• Optimizing vitamin intake is essential for improving patient outcomes in vascular diseases.
