Compare full servings, not scoops and pills
The front of a package can make two products look comparable even when their stated servings are very different. Start at the Supplement Facts panel. Note the serving size, the amount of collagen or protein per serving, and the number of servings in the container.
For capsules, check how many capsules make one serving. A bottle count is not the same as a serving count. For powder, confirm whether a scoop is supplied and whether the label defines a level or heaping scoop.
Where each format fits
Powder is flexible and can be mixed into a beverage or food, but taste, texture, and portability vary. Capsules avoid mixing and may travel well, but a larger declared serving can require several capsules. Neither format is automatically purer or more effective.
- Powder: easier serving flexibility; more attention to flavor and mixability.
- Capsules: convenient and pre-portioned; inspect the number required per serving.
- Both: compare source, allergens, added ingredients, testing, and cost per declared serving.
Calculate cost honestly
Divide the purchase price by the labeled number of servings, then compare products with similar declared amounts. If you also compare cost per gram, use the amount stated on the label rather than an estimate from container weight. Shipping, subscriptions, and flavored additives can change the practical value.
