Quick verdict. The 7.8 oz canister is a straightforward option for shoppers who eat fish and want an unflavored alternative to bovine collagen. The label identifies the fish species, and the dated price gives you a clear basis for comparing it with other powders. This review is based on the manufacturer’s label and price.

Ingredients, fish source, and allergens
The Supplement Facts panel lists collagen peptides from cod. Vital Proteins describes the source as wild-caught cod. The 7.8 oz label identifies cod in its allergen statement and says the manufacturing facility also processes milk and fish. If allergens or cross-contact matter to you, check the statement on the canister you receive because packaging may vary. Manufacturer’s sourcing information · 7.8 oz Supplement Facts

Pros, cons, and who it suits
Pros. It has one listed ingredient, identifies cod on the label, and states the serving in both tablespoons and grams.
Cons. At $39 for about 18 servings, the canister costs a little over $2 per labeled serving. The cod source rules it out for shoppers avoiding fish, including those with a cod allergy. The facility statement matters if you also track cross-contact with milk or fish.
The 7.8 oz Marine Collagen Unflavored makes sense if you want a plain fish-based powder and are comfortable with the cost. If your priority is value, compare the cost per gram with another marine powder using the same calculation. If you’re shopping across Vital Proteins products, the brand’s Original Unflavored Collagen Peptides uses a bovine source and has its own label and price. Vital Proteins bovine collagen review
