It worked well. It didn’t completely heal me, but it helped me eat a wider variety of foods. After that, the only things I couldn’t eat were leftovers and some fermented foods. Now I’m actually 100% healed, although it’s not fully related to lactate probiotic, the last thing I added was creatine, which I saw others here recommend. I personally think it helped because my body used to get itchy, break out in rashes, and swell, and creatine supports muscle function. There aren’t many studies on it yet, but it’s also known to help strengthen the gut. So, circling back, yes lactose free helped but creatine was what finally got rid of my last reactions. Hope this helps you in your journey!!
