How many protein drink (rtd) products does this matrix cover?

This matrix covers 63 protein drink (rtd) products from 16 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.

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.

What is the cheapest RTD protein per gram of protein?

Premier Protein 18-packs at Costco usually hit the lowest price per gram of protein in the RTD aisle. Fairlife Core Power is more expensive but uses real ultra-filtered dairy. OWYN is the price-leader on the plant-based RTD side. The matrix above ranks them in live order.
