Where does the label name the fish?
Turn the tub to Supplement Facts and find the row for collagen. Read the words in parentheses, then check the ingredient list and any nearby “Contains” statement. “Marine” on the front gives you a broad source. A name such as cod or pollock tells you which fish the maker used.
On U.S. dietary supplements, the FDA requires manufacturers to identify the species when an ingredient contains fish protein. The species can appear in Supplement Facts, in the ingredient list or in a separate “Contains” statement. If you skip straight to the bottom looking for that statement, you could miss the fish name higher up.
What do two marine collagen powders actually list?
On Orgain’s 8.5 oz unflavored Marine Collagen Powder, look at the last row of Supplement Facts. Just below “Collagen Peptides” you’ll see “from Alaskan Pollock.” The separate allergen statement to the right names the same fish.
Natural Factors’ unflavored Total Body Marine Collagen gives more detail about the part of the fish. Its collagen row identifies skin from North Atlantic whitefish and names cod, pollock, haddock and plaice. For someone checking for haddock, the word “whitefish” alone would miss the detail that matters.
How does shellfish appear on a label?
Fish and crustacean shellfish are separate categories under U.S. allergen labeling rules. Pollock is a fish. Shrimp, crab and lobster are crustaceans. Mollusks such as clams and scallops fall outside the federal major-allergen list. If you avoid a particular shellfish, read the full ingredient list for its name.
Read “may contain” or shared-equipment wording separately. It flags possible contact with an allergen during production. Manufacturers add those notices voluntarily. If you need to know whether a particular shellfish shares the production line, ask the maker before buying.
Frequently asked questions
Does “wild-caught” identify the species?
It describes how the fish was caught. Look for a fish name alongside the collagen ingredient or in the allergen statement to identify the species.
What if the store shows only the front of the tub?
Ask for a photo of the ingredient panel for that exact size and flavor. If the photo and the tub you receive name different fish, give the manufacturer the lot number and ask which species went into that batch before using it.
