Identify the product you are comparing

Write down the exact product name and form: powder, chew, liquid, or another format. Look for the source of the collagen and the other ingredients. “Collagen,” “hydrolyzed collagen,” and a branded ingredient name are not enough to establish that two products are equivalent.

Check the amount and the serving

Record how much of the named ingredient is supplied per labeled serving. A large number on the front may refer to the entire blend rather than one ingredient. If the amount is not disclosed, record it as unknown instead of estimating.

Then check how many servings the container contains for your pet’s labeled weight range. Product price alone can make a small container appear cheaper when the daily cost is higher. Our cost calculator uses the serving information you supply; it does not calculate a dose.

Read the rest of the label

Look for the intended species, age restrictions, storage instructions, expiration date, lot identification, and a way to contact the manufacturer. Bring the full ingredient list to your veterinarian, especially if your pet has food sensitivities or takes other products.

Match the evidence to the claim

A study of a different ingredient or a human product does not establish what this product will do for your dog or cat. Ask the manufacturer for the study supporting the specific claim, then use our evidence questions to read it critically.
