Vitamin D supplementation in hypertensive patients for hemoglobin level improvements

There is some evidence that suggests that vitamin D levels (25OHD) are inversely associated with hemoglobin levels and anemia risk ^[1]. This trial evaluated whether supplementation improved hemoglobin levels in hypertensive patients. 200 patients with deficient vitamin D were included. Patients received 2800 IU vitamin D3 daily or matching placebo for 8 weeks. The prevalence of anemic status and deficient 25OHD were 6.5% and 7.5%. All anemic patients had 25OHD levels that were >50nmol/L. The results showed that vitamin D treatment did not influence anemic status significantly nor did it have an effect on hemoglobin levels in the subgroup of anemic patients or in patients with very deficient vitamin D. The authors conclude that vitamin D supplementation for 8 weeks did not improve any of these parameters in hypertensive patients.
