Vitamin D deficiency in Muslim women

Assalam alaikum & peace to all

Came across these articles recently about how there is a high number of Muslim women who are
vitamin D deficient.
High Bone turnover in Muslim women with vitamin D deficiency
Vitamin D deficiency and Muslim Women

I think more research is in order to prove or disprove all this information. It is an interesting idea and a scary one as well. I think that many women who are completely covered forget that they do need to absorb sunlight to remain healthy. I'm not saying that you should uncover and walk around the streets, but perhaps keep in mind when you are alone and if you have access to a private backyard to 'soak up the sun' !!

Thoughts on these are always welcome!
