How we price collagen
We price 10 g of collagen, close to one scoop. Servings run from about 9 to 22 g, so we divide each tub’s price by its grams of collagen (how much to take). Prices are each brand’s own; Amazon sets its own, so check it the day you buy.
Buy the biggest tub you will finish
Tub size moves the price. Momentous costs $1.79 per 10 g in its smallest size (10 travel packs) and $1.09 in its largest (30-serving jar), about 39% less. Collagen powder keeps well in a dry cupboard, so the big tub is usually the better buy. Small tubs and travel packs cost up to $1.79 per 10 g.
Liquids and tablets cost several times more per gram than powder: liquid vs powder.
When you can skip it
Have a tub of plain collagen? Finish it, then size up. To choose by need, such as no beef or a drug test, see the best collagen.
