Grass-Fed Casein Protein
Transparent Labs offers the cleanest micellar casein on the market, sourced from 100% grass-fed cattle with zero artificial sweeteners or dyes. It provides a sustained release of amino acids throughout the night, which is clinically proven to support muscle protein synthesis during sleep.
Quality & Materials
Contains 25g of micellar casein per scoop. Sourced from grass-fed cows which typically yields a better fatty acid profile. No fillers or 'protein spiking' ingredients.
Evidence & Testing
The product is Informed Choice certified, ensuring it is free from banned substances. The use of micellar casein specifically for pre-sleep recovery is supported by the landmark Res et al. (2012) study.
Brand Transparency
Full label disclosure; no proprietary blends. COAs are available on their website by entering the batch number.
Value Assessment
At roughly $2.00 per serving, it is a premium product, but the quality of sourcing and lack of synthetic additives justifies the cost for health-conscious consumers.
Why Not Alternatives?
Unlike Optimum Nutrition or MusclePharm, Transparent Labs avoids sucralose and acesulfame potassium, using stevia instead. They also provide accessible Certificates of Analysis (COA) for every batch, which is rare in the supplement industry.
