I cannot eat regular vitamins (the giant ones that you swallow whole) without feeling nauseous for hours afterwards. I only eat gummies now. Vitafusion are good and they do make a Vitamin D gummy.

Here us a link to a site where vitamins were tested and then ranked (it tells you what the criteria was and what tests were used.)

I linked to the Vitamin D results but they tested many supplements.

most D3 I've seen is tiny and easy to swallow. Most dentists say no to gummies and chewables.

Costco has a couple chewables I'll probably consider. For that reason, how sometimes vitamins make your stomach feel funky, I'm thinking chewables would be easier to take daily.

Look into Bio-D-Mulsion Forte by Biotics Research. I originally purchased it from my kinesiologist, but you can also buy it from Amazon. One drop is 2,000 IU of vitamin D (as cholecalciferol). Other ingredients - water, gum arabic and sesame seed oil. Bottle is 1 ounce and lasts a very long time.

Choose sublingual over chewable. Better absorption. My naturopath has me on these. I also take B and biotin from this brand.

I take a gummie multivitamin too, but in the winter I do the vitamin D drops.
