How to read this table
How is Omega-3 declared on the label?
Fish oil labels declare the total fish oil (1,000mg, say) separately from the omega-3 content inside it. The amount on this page is the figure declared as "omega-3", not the fish oil total — confusing the two shifts the unit price several times over.
How much does Omega-3 pricing vary between products?
Price per mg ranges from a low of $0.000044/mg to a median of $0.000924/mg. The median is 21× the lowest. Products with noticeably lower prices cluster near the top, and the distribution flattens toward the middle.
Price per mg is computed for 686 of the 849 listed (81%). The rest, missing a sale price or amount, are placed at the bottom of the ranking and excluded from the statistics above.
The Omega-3 amount per serving ranges from 0.45mg to 8,000mg, with a median of 690mg. The maximum is only 12× the median, so most products cluster near the median, and the price-per-mg ranking reflects price differences more than amount gaps.
The products in this list come from 187 brands, and the sort order is determined solely by price per mg.
What are the limits of this Omega-3 comparison?
When a label breaks out only EPA and DHA and gives no combined "omega-3" line, that product may have no omega-3 amount in this table. Those products can still be compared on the EPA and DHA pages.
