Well it turns out I can't make D3 from the sun because my levels actually dropped from 29 ng/dl to 24 ng/dl despite having near full body exposure to the sun at least 3-4 days a week for the past couple of months. I hate taking supplements but it seems like I'll have to take d3. Does anyone know if there's a supplement manufacturer that makes d3 in the USA/Europe? It seems like all of it comes from China and I will not ingest anything that comes from there. Thanks!
