What “type” means
Collagen is a family of structural proteins. Type I is abundant in skin, bone and tendons; Type II is the principal collagen in articular cartilage; Type III is found in tissues including skin and blood vessels. These are broad biological patterns, not a simple map where one type belongs to one body part only.
Type is not the same as form
A label may also describe collagen as peptides, hydrolysed collagen or undenatured collagen. Those words describe how the ingredient has been processed or presented, not a new Roman numeral. That distinction matters because trials of one form cannot automatically be applied to another.
Read Balmve’s label precisely
The current More Than Collagen panel lists an 8,000 mg multi-collagen blend from bovine Types I and III and marine Type I peptides, plus 40 mg undenatured Type II collagen on a separate line. Those are label facts. They do not mean the finished formula has been clinically proven to improve a joint outcome.
A better comparison
Compare source, form, amount and the study population together. If the amount is grouped into a blend, do not guess the individual split. If a study uses a branded ingredient or a different dose, keep that difference visible.
