How these numbers were made

On every product page, Amazon groups what reviewers write into topics and counts how many reviews mention each topic in a positive or a negative way. Adlicio read those counts for 8 collagen powders on 12 November 2026 and added them up. Nothing is estimated.

The products are 8 widely reviewed collagen powders on Amazon US, each with at least 2,000 ratings. This is a sample, not every product in the category.

Amazon shows at most 8 topics for a product, so a topic that is missing for a product is not counted for it. One review can count under more than one topic.

Amazon names the same topic in different ways. These were put together: Taste (Taste, Tasteless); Mixing and dissolving (Blendability, Clumping, Dissolvability, Mixability, Solubility); Skin, hair and nails (Hair and nail growth, Hair and nail health, Hair growth, Nail growth, Skin and hair, Skin benefits, Skin improvement); Joints and pain (Joint health, Joint pain, Joint support, Pain relief).
