View Full Version : Questions about protein powders

I've been using a whey isolate protein powder but i can't figure out if there's lactose?? in it?

Also anyone know off hand how long a protein shake would take to digest?

I don't know if it's the high protein or possible lactose in the powder but it gives me the runs from time to time help

With a whey isolate there would be a bare minimum of lactose. Check the label for grams of sugar per serving. That sugar is lactose.

On an empty stomach a whey isolate shake with water doesn't take long to hit the blood stream. You'd probably see amino acids in the blood in 20-40 minutes. If you've eaten anything the last twelve hours or so that could be altered, though.

It could be a variety of things giving you the runs, although I'd be surprised if it was either the lactose or protein. It's probably an isolated incident or some other ingredient in the shake.
