Whey protein and nausea?

iKristine

Does anyone else get nausea (upper abdomen ache) consuming whey protein? This has happened last 5 or so times like clockwork. Almost like I want to throw up, but then passes after hour? I'm not lactose intolerant, this same protein never bothered me before (+6lbs). Don't matter one scoop once, 3 scoops during day. Same results.

I know it's nothing to do with other food choices, as they are all the same as well. Doesn't matter whether empty stomach or not.

There are lots of topics on MFP about protein bars giving gas. Whey is a milk product, do you do okay with milk products? (oh, you just said you usually are fine with those). I read lables on a lot of protein bars and to keep calories low they put in all sorts of sugars. Some I don't want to eat. Could it be the sweeteners?

Don't think so?

The closest thing I found online that I thought might explain it, is from a dietetics website that said your stomach enzymes sometimes aren't enough to break down the protein. The result is you get stomach ache until it can. That ir had to do with the quantity of protein. But we are talking 27g here.

So either I spontaneously started rejecting protein.. or something. It's really weird. It's an ache that can linger. I tried last night eating the shake slower, over like an hour.. while I still felt ill, it wasn't nearly as bad as when I chug it and have to go lay down for hour.

I use to get really bad aches when I took certain brands of whey protein, so if it started to bother me I'd switch tubs and try a new brand. Promasil always kicks my a**, so i tried Optimum Nutrition and Allmax Isoflex and both have been good to go since. So I'd suggest finish the tub if you can and buy a small tub of another brand that you like the ingredient makeup of and go from there. Failing that there are also egg proteins and soy that may prove a better option for you.
