                                Milk is composed of approximately 80% casein and 20% whey, a biological ratio that is one of the primary drivers behind **why casein protein is more expensive than whey protein**. This fundamental difference in natural abundance, coupled with distinct manufacturing processes, creates a significant price disparity in the supplement market.
