TMI but need advice...

[sillykitty 10,708]

I developed a whey Protein isolate intolerance about 3 weeks post op. It cause extreme nausea, about 45 minutes after I started to ingest anything that contained whey protein isolate. I tried it in different forms, premade shakes, powders, bars & protein Water, reacted the same to all of them.

I had to find alternatives without whey. I first tried vegan powders, shakes and bars. I couldn't handle the way the tasted. I finally settled on Muscle Milk Pro premade shakes, Medifast powdered shakes, and Medifast chicken noodle Soup, Medifast Crunch Bars, and several of the Soups on Barbaric Pal. There are other premade shakes I can handle, like Advent Edge Carb control, but Muscle Milk tastes better to me.

Hope that helps!

I'm surprised no one has mentioned this, but have you run it by your doctor and/or nutritionist??

Where does one find A2 milk? Is there a well-known brand like Sealtest, Borden. Fairlife or do you have to know a farmer, or are there regional ones I havent,heard of? I live in the Midwestern US( in Ohio).😔

Maybe this is dumping syndrome? Is there a lot of sugar in your Protein Shakes?

It was definitely the milk. I tried to pills and it helped a bit, but not enough. I went back to muscle milk (lactose-free), and I have been perfect and feeling a lot better. Oddly enough, I had also noticed an increased heart rate after drinking my Protein Shake, and that symptom disappeared too.

It’s still possible that whey Protein isolate isn’t the issue. Muscle Milk doesn’t contain whey, so it might be that you have eliminated whey, and not related to lactose at all. Do you consume anything else with whey protein, like powders, bars, or even Protein20?

I’ve had the clear Protein Drinks and I am fine with those. Im on liquids for three weeks, so no bars yet.

Muscle milk contains whey

But it is pretty far down its list of ingredients.

After having a day of no milk and feeling great, I am going with a lactose intolerance.

Whey Protein concentrate is in the less than 1% section. I’m not sure if it agrees w me because it is different than whey protein isolate or if it in such a small amount that it doesn’t be matter
