South Indians often have shorter stature, more visceral adiposity, and darker skin, leading to significant vitamin D deficiency.

“in South Indians they're shorter and vertical height they tend to have a little bit more visceral adiposity so a little bit more larger potbellies in the north as you move further up north probably a little bit more lean body mass basically a little bit taller the skin type is well - in the South darker skin we see a lot more significant vitamin D deficiency when when I see these individuals they have a vitamin D level maybe three or four basically so way down in single digits”
