Vitamin D price per mcg — cheapest first

Most vitamin D labels declare IU. This page converts at 1 IU = 0.025mcg and reports everything in mcg — 1,000 IU is 25mcg, 5,000 IU is 125mcg. D3 (cholecalciferol) and D2 (ergocalciferol) share the same IU definition and therefore the same conversion factor, so both forms land on one axis.

Price per mcg ranges from a low of $0.000098/mcg to a median of $0.0289/mcg. The median is 294× the lowest, so the cost of the same 1mcg of Vitamin D spreads over a hundredfold across products. That means the per-unit gap between products near the top and the middle of the ranking is that large.

Price per mcg is computed for 3,357 of the 3,610 listed (93%). The rest, missing a sale price or amount, are placed at the bottom of the ranking and excluded from the statistics above.

The Vitamin D amount per serving ranges from 0.02mcg to 1,250mcg, with a median of 25mcg. The maximum is 50× the median, so high-dose singles and blends listing a small Vitamin D amount sit in the same table.

The products in this list come from 529 brands, and the sort order is determined solely by price per mcg.

Products classified by label form notation number 3,119 (86% of the total), and the most frequently noted form is Cholecalciferol (D3) with 2,985. Products with no form notation, or whose notation does not match the classification rules, do not appear on the per-form pages, so the per-form product counts sum to less than the total product count above.

Because vitamin D is declared in mcg, the price per mcg runs out to five decimal places. The list also picks up products where vitamin D is one component among many — omega-3 blends, multivitamins — and for those the price per mcg charges the whole product price to vitamin D alone.
