How to read this table
How is Protein declared on the label?
Protein is declared in grams, and a serving is one or two scoops, which makes the price per serving larger than a capsule product’s by nature. The price per gram on this page is the price per serving divided by the grams of protein in that serving.
How much does Protein pricing vary between products?
Price per g ranges from a low of $0.0217/g to a median of $0.1208/g. The median is 5.6× the lowest, so the top and the middle differ by a few times.
Price per g is computed for 2,599 of the 3,021 listed (86%). The rest, missing a sale price or amount, are placed at the bottom of the ranking and excluded from the statistics above.
The Protein amount per serving ranges from 0g to 60g, with a median of 15g. The maximum is only 4.0× the median, so most products cluster near the median, and the price-per-g ranking reflects price differences more than amount gaps.
The products in this list come from 477 brands, and the sort order is determined solely by price per g.
What are the limits of this Protein comparison?
Container size and scoop size differ from powder to powder, so declared servings per container are all over the place. When servings per container is missing from the label data, it is estimated from the product name and package size, and the resulting price per serving is marked "est." in the table. The price per gram on any row carrying that mark rests on the same estimate.
