Vitamin D3 Superior to D2 for Muscle and Heart Health: ICMR Study
A new study by the Indian Council of Medical Research's National Institute of Nutrition suggests that Vitamin D3 demonstrates greater efficacy than Vitamin D2 in supporting cardiovascular and skeletal muscle function.
LSN India ·
Research conducted by ICMR-NIN has found that Vitamin D3 outperforms its counterpart Vitamin D2 in enhancing muscle strength and cardiac health, findings that could influence public health recommendations across India. The study examined the comparative effectiveness of both forms of the essential micronutrient in maintaining physiological functions critical to overall wellness.
Vitamin D deficiency remains a significant health concern in India, with widespread prevalence attributed to dietary patterns, limited sun exposure among certain populations, and indoor occupational trends. The distinction between D2 (ergocalciferol) and D3 (cholecalciferol) has long interested researchers, though D2 has traditionally been favored for large-scale fortification and supplementation programs due to cost considerations.
The ICMR-NIN findings suggest that D3's superior bioavailability and efficacy in supporting muscle function and cardiovascular health warrant consideration in future nutritional policy decisions. This research is particularly relevant for India's aging population and individuals at higher risk of musculoskeletal disorders.
The results come as public health authorities continue evaluating optimal strategies for addressing vitamin D insufficiency across diverse Indian populations. Healthcare professionals may need to reassess supplementation recommendations, particularly for individuals with cardiac risk factors or those experiencing age-related muscle decline.
