Vitamin D occurs in nature in two forms: vitamin D3 and vitamin D2.<\/p>\n
While D3 is synthesised through sun\/UV exposure and obtained primarily from animal-based foods such as eggs, fish and organ meats and from supplements, D2 is derived from wild, cultivated or sun-dried mushrooms, UV-B-irradiated yeast, plant-based sources and some dietary supplements.<\/p>\n
For food fortification, both D2 and D3 are used. However, D2 is a more preferred fortificant in certain countries due to widespread vegetarianism or among people who follow a strict vegan diet.<\/p>\n
\u201cVitamin D plays an important role in modulating skeletal muscle mass, structure, and function, however, the differential impact of D2 and D3 remains inconclusive. In this study, we found that D3 has a greater impact than D2 in improving skeletal muscle size and function during both maintenance and recovery phase,\u201d the study said.<\/p>\n
While both forms are used in supplements and food fortification, evidence on whether the two forms have similar effects beyond bone health has remained limited.<\/p>\n
To study the differences between the two forms, the researchers used weaning male Sprague-Dawley rats and fed them diets containing vitamin D2, vitamin D3, a combination of both, or a vitamin D-deficient diet.<\/p>\n
The researchers assessed body composition, muscle strength, skeletal muscle structure and metabolism, and markers related to cardiac function.<\/p>\n
Dr Bharati Kulkarni, Director, ICMR-NIN, said, \u201cThe findings indicate that vitamin D3 may be more effective than vitamin D2 in maintaining and restoring skeletal muscle and cardiac functions.\u201d<\/p>\n
She said further studies are needed to establish the effects of the two forms of vitamin D on skeletal and extra-skeletal functions and their implications for supplementation and fortification programmes.<\/p>\n
According to the World Health Organisation-Food and Agriculture Organisation (WHO-FAO), micronutrient supplementation is the fastest method to improve the micronutrient status of populations, while fortification can be a cost-effective public health intervention with a sustained impact.<\/p>\n","protected":false},"excerpt":{"rendered":"Vitamin D occurs in nature in two forms: vitamin D3 and vitamin D2.
