I am lactose intolerant, and so far the best shake for me is Ispoure Lo-Carb; it's 99% lactose free. I've tried soy products and other lactose-free products, and this one is the safest on my stomach. Even the brand recommended by my doctor's office was too harsh.

Problem is, even with the Isopure Lo-Carb, I get an upset stomach.

I don't know how I am going get through the liquid stages when I can't tolerate any of the formulas.

Can I use Immodium during the liquid phase or will that interfere somehow?

Thanks in advance!

Yes, you can use Immodium. Have you tried the ready to drink (RTD) shakes from Medifast? They are soy based. I am allergic to milk and did fine with that brand.

have you tried any of the lactase-replacement products that aid digestion of lactose? The names of them escape me right now....

Lactaide is the one I am familiar with.

I do about as well with Medifast RTD as I do with Isopure, and I went with Ispure only b/c I've read it's not a great idea to have a lot of soy if you have a thyroid condition (I'm hypo). Lactaid has no effect.

Thanks for your replies. I am glad that at least I can use Immodium.

Thanks again!

I didnt drink a single Protein shake through the liquid phase and I"m still here to tell the tale. I hate em, and I dont believe you need 10 million grams of protein a day anyway.

I had juice, Water, yogurt, and loads and loads of Soup - real soup that I made and it was full of lentils and Pasta and meat and vegetables and I just blended it to varying degrees depending on my progress - with stock or a can of tomatoes. I even blended spaghetti sauce.

I did fine, I lost loads of weight and I didnt keel over from protein deficiency. I took a liquid Multivitamin.
