Folate depletion impairs one-carbon metabolism, leading to elevated homocysteine, endothelial dysfunction and potential promotion of atherothrombotic events. This medication is commonly used for Hypertension.
Meta-analyses of randomized trials show that folic acid supplementation lowers homocysteine and modestly reduces stroke and overall cardiovascular disease risk in some populations, especially where baseline folate status is low, highlighting the adverse vascular profile of folate deficiency.

Some side effects may be linked to nutrient depletion caused by this medication.
Calcium channel blockers (CCBs), particularly nifedipine, can cause gum tissue overgrowth (gingival hyperplasia) in both men and women. Studies suggest a dose-dependent link with CCBs potentially doubling the risk. Studies also confirm a link between CCB use (like amlodipine and nifedipine) and gingival hyperplasia, even beyond factors like poor hygiene. Research suggests impaired folate uptake in gum tissue might be another key contributor. Supplementation with folate to help protect against CCB-induced hyperplasia may be beneficial.
