Collagen powders, capsules and drinks can differ in animal source, allergens, serving basis and added ingredients.
Animal or other source
01Compare: Record bovine, marine, porcine or other source only when the current label states it.
Why it matters: Source can affect dietary preference and allergen considerations.
Evidence check: Do not infer species from a product image, “marine beauty” category or retailer filter.
Collagen material and stated amount
02Compare: Compare the named collagen or peptide material and amount per stated portion.
Why it matters: A total blend, scoop or drink volume is not necessarily the collagen amount.
Evidence check: Keep form, amount, unit and portion together; mark type or amount as unknown when undisclosed.
Allergens and added ingredients
03Compare: Compare fish or other allergens, flavours, sweeteners, vitamins and any additional active ingredients.
Why it matters: A flavoured blend and plain collagen are not like-for-like products.
Evidence check: Use the exact flavour’s ingredients and warning panels.
Format, servings and subscription fit
04Compare: Compare powder, capsule, sachet or liquid use, stated servings, pack size and current repeat-order terms separately.
Why it matters: Convenience and subscription discounts can hide higher unit cost or unwanted commitment.
Evidence check: Calculate on the same labelled amount basis and recheck live subscription conditions before ordering.
Three checks before checkout
Enough detail to make the choice better informed and clearer, without turning a quick buying decision into a compliance manual.
- 1 Identify bovine, marine or other source, allergen wording, format, ingredients and exact pack.
- 2 Match the exact flavour, variant, pack and formula rather than a similar marketplace image.
- 3 Use the current physical label for ingredients, allergens, warnings and stated serving information.
