Can water be fortified by vitamin D
And what will be the % DV or the permitted quantity per liter
will exposure of the fortified bottles to sunlight destroys the vitamin
Is it safe for all ages without toxicity from overdose
I have not seen any references to Vitamin D being affected by water in under a month.
I believe that a good way of getting Vitamin D is to put it into various drinkables – including water, milk, fruit juice, etc. Using a small amount of vitamin D as a mouthwash also looks promising – especially when you want to get the vitamin D into your blood stream quickly or if you have gut problems
