I am mildly lactose intolerant. I can cope with a cup of tea, for example, but a milky hot chocolate will give me wind and the runs. I occasionally take lactase tablets if I’m about to eat or drink something that may have more lactose in it than I can cope with.
Are some lactase tablets better than others? I have no idea which brand I had last time, but the current ones are definitely not as effective. Of course, I may just have become more sensitive, but my tolerance of small amounts of lactose does not seem to have changed.
