Biochemical parameters, including folate, vitamin B12, and homocysteine levels, were assessed using the Chemiluminescence Immunoassay technique. Hypertension was defined as SBP\u2009\u2265\u2009140\u2009mmHg and DBP\u2009\u2265\u200990\u2009mmHg or the use of antihypertensive medication.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The findings revealed a sizable prevalence of folate (26.4%) and vitamin B12 (30.7%) deficiencies, along with a high prevalence of hyperhomocysteinemia (64.8%). Homocysteine levels showed an inverse relationship with folate and vitamin B12 levels, though this association was evident only up to a specific threshold. Further, hyperhomocysteinemia was associated with prehypertension and hypertension, and low folate with prehypertension. Paradoxically, a positive correlation was observed between folate levels and blood pressure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These findings underscore the widespread prevalence of micronutrient deficiencies and hyperhomocysteinemia and their potential association with hypertension. The study also highlights the importance of establishing upper cutoff levels for folate and vitamin B12 to refine dietary and supplementation guidelines. The positive correlation between folate levels and blood pressure suggests potential interference with cellular nutrient uptake in hypertensive individuals, warranting further
