Transparent Labs Grass-Fed Casein is a micellar casein protein from grass-fed cows, built to digest slowly - most people use it before bed or between meals rather than post-workout, where a faster whey is the better fit. 25g protein, 0g fat and 2g sugar per scoop, naturally flavored with no artificial dyes or sweeteners. Ask our staff if you're not sure whether casein or whey fits better into your day.
