Does collagen smell bad

Collagen itself typically does not have a strong odor; however, its smell can vary depending on the source and processing method. Marine collagen may have a slight fishy scent, while bovine or porcine collagen may have a more neutral smell. In general, high-quality collagen supplements are often odorless or have a mild scent that is not considered unpleasant. If a collagen product has a strong or off-putting smell, it may indicate poor quality or spoilage.
