Besides sardines for breakfat, etc, how can I get lots of vitamin D from food or supplementation?
Buy a bottle of vitamin D supplements. Mine come in units of 400. I take a multivitamin (contain 400 units of vit D) plus the straight D pills numbering four (4). That is a total of 2000 units.
If you take any 'supplements,' just be sure that all the ingredients are from 'once live' sources. Synthetic sources can destroy large amounts of nucliec acid in your cells, thus leading to the production of abnormal cells, among other things.
Carlsons Lemon flavored Cod Liver Oil.....Lots of Vit D AND DHA, which is really good for you, too.
