Does Whey Digest Faster? What Lactase Actually Does
Whey is rapidly digested compared with casein, but that does not establish that it is the fastest protein overall or the easiest for everyone to tolerate. Lactase breaks down lactose, the sugar in milk; it does not make whey protein itself digest faster.

Key takeaways
- Whey is rapidly digested compared with casein, but that does not establish that it is the fastest protein overall or the easiest for everyone to tolerate.
- Lactase breaks down lactose, the sugar in milk; it does not make whey protein itself digest faster.
- Lactase may help with the lactose in a product, but the claim that most whey products contain added lactase is not supported by the available evidence.

The claim is partly right, but overstated. Whey is a fast-digesting protein, especially compared with casein. But that does not prove it is the fastest protein overall—or the easiest for everyone to tolerate. The explanation about lactase mixes up protein digestion with lactose digestion. 1

Whey is fast-digesting, especially compared with casein
Whey is rapidly digested, while casein is digested more slowly. That comparison supports calling whey a fast-digesting protein, but it doesn’t establish a universal ranking of all proteins or mean whey suits everyone best. 1

Lactase acts on lactose, not protein
Lactase is an enzyme that breaks down lactose, the sugar in milk. If a whey product contains lactose, added lactase may help someone with lactose intolerance digest that sugar. It does not speed up the breakdown of whey protein itself. 4

The claim that most manufacturers add lactase to whey products is also not established by the available evidence. Check the ingredient list to see whether a specific product contains it.
A more accurate version would be: “Whey is a fast-digesting protein. Added lactase may help people with lactose intolerance digest the lactose in a product.” 3
