Vitamin D has been implicated in a range of physiological processes beyond its classical role in calcium homeostasis. Vitamin D undertakes a protective role in CVD by demonstrating a negative association with hypertension, inflammatory response and oxidative stress. Fermenta, a leading manufacturer of Vitamin D, presents this D-Essence Newsletter to highlight the latest research on the Role of Vitamin D in Cardiovascular Wellness. Vitamin D supplementation might be beneficial for ASCVD prevention The association between Vitamin D supplementation and ASCVD was investigated by leveraging data obtained from the UK Biobank. Among 4,09,822 participants, 20.7% and 34.4% were Vitamin D deficient (<30 nmol/L) and insufficient (30 to <50 nmol/L), respectively, with only 4.3% using Vitamin D supplements regularly. Vitamin D deficiency significantly increased ASCVD risk including its individual endpoints (IHD, cerebrovascular disease, atherosclerotic disease and PAD) compared to Vitamin D sufficiency (50 to <100 nmol/L). After adjusting for confounding variables, Vitamin D supplementation reduced the risk of total ASCVD and IHD by 6% and 10%, respectively, Vs. non-users. Sha S et al. Clin Nutr. 2025 Apr 16;49:118-127 Vitamin D supplementation potentially regulates blood pressure A systematic review of 12 studies assessed the impact of Vitamin D supplementation (intervention duration varied from 8 to 48 weeks) on BP. A study which included patients having the highest baseline BP (Vs. other studies) and employed 50,000 IU/week Vitamin D supplementation for 8 weeks demonstrated the greatest BP reduction of -28.44 / -7.38 mmHg. In remaining studies, the BP reduction ranged from -0.5 to -4.5 mmHg for SBP and -1 to -5 mmHg for DBP and this variability was prominently influenced by dosage, duration and baseline BP levels. Overall, Vitamin D supplementation substantially reduced BP levels particularly at higher doses over shorter durations. John H et al. Cureus. 2025 Mar 25;17(3):e81150 Vitamin D levels may be inversely associated with CVD risk in T2DM A cross-sectional study explored the correlation between Vitamin D levels and CVD risk among T2DM patients. Among 1,378 individuals, after adjusting for potential confounders, Vitamin D deficiency (< 12 ng/mL) increased the odds of CVD by 2.25-fold compared to Vitamin D sufficiency (≥ 20 ng/mL). This negative association was particularly significant among women, older adults, normal-weight (BMI < 24 kg/m2) and obese (BMI ≥ 28 kg/m2) adults. Additionally, Vitamin D deficiency increased the risk of overweight (24 ≤ BMI < 28 kg/m2) / obesity, hypertension, hypertriglyceridemia and reduced HDL-C by 57%, 81%, 56% and 67%, respectively, Vs. Vitamin D sufficiency. Zhang N et al. Sci Rep. 2025 Feb 22;15(1):6454 Disclaimer: The contents of this issue of ‘D-essence’ have been developed by FourC Healthvistas Pvt.
