Complete Casein Protein Matrix: All 10 Products Compared (2026)
Every casein protein we track, in one matrix. Casein digests slowly, so it is the protein of choice before bed or between meals when you want a steady amino acid trickle for 6-8 hours. There are not many casein products on the market compared to whey, which makes side-by-side comparison especially useful. This page shows all 10.
How to Read This Matrix
Twelve columns, one row per product. The columns are: rank by Value Score, brand (links to the brand page), product name (links to the full live-price page), flavor, tub size in pounds, grams of protein per serving, total servings in the tub, calories per serving, cheapest in-stock price across our 12 tracked US retailers, the retailer at that price, the Value Score (0-100, higher is better), and short notes calling out the most relevant detail like grass-fed, hydrolyzed, or organic.
How casein is different
Casein forms a gel in the stomach and digests over hours instead of minutes. The result is slow-release amino acids, which research links to better overnight muscle protein synthesis. The trade-off: thicker mix, slower satisfaction, and a higher price than whey blend.

Top 5 Winners by Different Metrics
The single Value Score column is the right place to start, but it is not the only way to slice this matrix. Here are five different angles on the same product set:
How We Built This Matrix
Every row above is generated directly from our live product catalog. When the scraper checks each retailer (every two hours throughout the day), the cheapest in-stock price wins the right-hand column. Value Score is recalculated whenever a price changes. We do not score products that are out of stock at every retailer.
To learn more about how the Value Score combines price per gram with retailer reliability, label-claim accuracy, and third-party testing, read how it works and our editorial standards. The methodology is the same across every matrix on this site.
FAQ
How many casein protein products does this matrix cover?
This matrix covers 10 casein protein products from 8 different brands. It is a complete view of every product in this category that we currently track. New products are added as our scrapers find them and old products are removed when they go permanently out of stock.
How often is this matrix updated?
Prices are refreshed automatically every two hours across all 12 retailers we track. Value Score, ranking order, and the cheapest-retailer column update whenever a tracked price changes. You can see live scraper health at /scraper-status/.
Why is the cheapest product not always the highest Value Score?
Value Score combines price per gram of protein with retailer reliability, label-claim accuracy from third-party testing, and customer-reported flavor and mixability. A very cheap tub from a brand with a recall history or thin label disclosure can lose to a slightly more expensive tub from a brand that tests every batch. Read the full methodology at /how-it-works/.
Can I sort the matrix by a different column?
Not yet on this page. We rank by Value Score because that single number rolls in the most decision-relevant factors. If you want to sort by raw price, protein per dollar, or pack size, the /best-value/ live rankings page lets you filter and sort across every category.
Should I take casein before bed?
Casein digests slowly over 6-8 hours, which is why it is the go-to before-bed protein. Most published meta-analyses show a small but consistent advantage for evening casein on overnight muscle protein synthesis. Daytime casein is fine but offers no advantage over whey blend at meals.
Where can I see live retailer prices for any product in this matrix?
Every product name in the matrix links to its full live-price page. On that page you will see all 12 retailers we track, their current in-stock prices, a price history sparkline, and a Value Score breakdown. You can also browse the full casein protein category at /casein-protein/.
