Vitamin C price per mg — cheapest first

Labels call both ascorbic acid and its salts — sodium ascorbate, calcium ascorbate — "vitamin C", and the declared amount is stated as ascorbic acid equivalent. This page reads that figure directly, in mg. Liposomal and time-release products declare their amounts the same way, so the delivery format does not show up in the price per mg here.

Price per mg ranges from a low of $0.000030/mg to a median of $0.005941/mg. The median is 200× the lowest, so the cost of the same 1mg of Vitamin C 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 mg is computed for 3,943 of the 4,284 listed (92%). The rest, missing a sale price or amount, are placed at the bottom of the ranking and excluded from the statistics above.

The Vitamin C amount per serving ranges from 0.06mg to 5,000mg, with a median of 100mg. The maximum is 50× the median, so high-dose singles and blends listing a small Vitamin C amount sit in the same table.

The products in this list come from 581 brands, and the sort order is determined solely by price per mg.

Vitamin C products commonly declare 1,000mg or more per serving, which pushes the price per mg below one decimal place. That number cannot sit next to the unit price of another ingredient — a milligram means something different from ingredient to ingredient, so vitamin C per mg and vitamin D per mcg are not comparable figures.
