best unflavored collagen powder

Common sources include bovine collagen (often labeled grass‑fed or pasture‑raised), chicken, marine sources (wild‑caught fish), and egg‑derived collagen. Some products are also marketed from bone‑broth sources or as blends of multiple collagen origins.

Many unflavored powders contain Type I and Type III collagen. Multi‑collagen formulas may include a broader set—commonly Types I, II, III, V, and X—and some brands advertise up to 10 different collagen types.

Many unflavored powders dissolve easily in hot or cold liquids and blend well into smoothies and recipes. Some users report occasional clumping in cold liquids unless the powder is shaken or blended.

Stir or blend it into hot or cold beverages (coffee, tea), smoothies, oats, and protein shakes. You can also add it to baked goods and other recipes to boost protein without changing the flavor.

Package sizes range from small tubs (about 4–9 oz) to larger containers around 20 oz. Serving counts vary by product—examples include roughly 25 servings for smaller tubs and about 63 servings for larger multi‑collagen containers.
