I had massive problems with this, as I had serious problems with gas no matter what I ate. Switching to Huel was a challenge in the gas department. I have been almost exclusively on Huel since August of last year, and although I still have issues, they are more in line with normal levels. My situation is likely quite different, and my approach is rather extreme, but I agree with other comments here. The solution for me was a lot more water and a lot of probiotics. Once my body adapted to the probiotics, the gas reduced substantially. I use a combination of probiotics with totaling about 400 billion CFU per day. That is probably way more than most people need, but my digestive system is a train wreck that is slowly becoming better thanks in no small part to Huel. In my case, I use RAW Ultimate Probiotics, and 1MD probiotics. I try to drink one gallon of plain water each day in addition to the one gallon of Huel I consume. This has helped me keep the gas under control so far. I truly believe finding the right type and amount of probiotics is challenging, as there are too many variables for a one size fits all solution. In my case, I had zero effect at all until I took the RAW probiotics, which initially had an extreme effect, but they are 100 billion CFU and 34 strains per capsule, so it it not like the typical drug store variety that might have 10-20 billion CFU and only a few strains. And I agree with other comments about fiber being part of the cause. The probiotics supposedly help digest fiber better, so there is less gas.
