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.

Buy a bottle of vitamin D supplements.

will I find this on the bottom of the label?: "Vitamin D sourced from seafood byproduct processed in China" :)

Make sure it's D3, not D2 (it will say so on the label).

D2 is not the right form for supplementation. But the best way to supplement is sunlight.
