The plot thickens.......... and I think I may be on to something here! I've been taking a protein supplement for the last two months or so. For the first several weeks I didn't experience any major side effects from it. More recently, within the last couple of weeks, about 15 min. after I take it I begin to have sharp pains in my stomach with nausea. The pain and discomfort is radiating, comes and goes. It lasts for about 10-15 min. and then disappears almost as suddenly as it comes on. I hadn't even noticed it before but one of the ingredients in this protein powder is....... wait for it........ wait for it............ any guesses?.............. wait for it.............. Lactase enzyme! I feel like Sherlock Holmes! LOL Now I'm convinced that I'm correct. If any brave soul who has had a bad experience with the tablets would be willing to try the milk, where the Lactase has already converted the Lactose, I would be very interested to hear about the experience. My guess is that the side effects would be substantially reduced in intensity if not virtually non-existent. So....... since I was first, who is going to be second?
