Prevent Vitamin D Deficiency

Because Vitamin D deficiency is a worldwild constrain, there muat be a solution.I worked to reach the base of any problem. I got a solution which may truely help to solve the problem from its roots.

There's a known technology named as "gene therapy" this will allow us to access the gene and to reach the base.by this will can activate genes that don't form Vitamin D in places other than Kidney and Liver, as to access those it take longer time than expected.Gene therapy technology succeded previously for other disease,so why not to try it to prevent Vitamin D deficiency?
