I take these in the winter
Metagenics Vitamin D3 and Vitamin K2 10,000 IU with MK-7 - one every few days
Sunray® Calcifediol Vitamin D Supplement - when I'm feeling a cold coming on, and after I catch something
I do not believe pale skinned people should be in direct mid-day sunlight. A tanning bed is even more intense. Yes, it creates vitamin D, but it also damages dna, and people don't get enough IR light in the winter to counteract the metabolic stress caused by UVB/C. It's more efficient to take it orally.
