Thx for the info. I live in FL where the sun is readily available. However, I don't do outside activities all that much because it's so hot. Therefore, the majority of sun exposure comes from walking from my car to the bldg/house/stores/etc. Rarely, am I just outside for hours on the weekend. I wonder if brief exposure enough. When we're outside for lengths of time, we put on sunscreen/block to ensure we are not overexposed. The dh had cancer previously so we're very cautious but we might be short changing ourselves in the Vit D dept with our efforts of being cautious. I'll research this further.
Diva, I'm unsure what cancer your DH had but be sure to research before upping his intake. I know for prostate cancer some studies show it increases prostate cancer cells. Also, if he his on anti cancer meds you need to check with his Dr. also.
