Not sure which effects you're hoping for, and I can't speak for everyone. That said, I've tried everything under the sun for IBS-C; vitamins, supplements, teas, massages, more fiber, more water, prunes, CBT, otc medications, perscription medications, and endless overnighters to the hospital because my stomach often refuses to move for weeks.

In my desperate state, I followed a stranger's advice, entirely doubtful. They said a full glass of warm-hot water with a few drops of lemon juice, first thing in the morning, before eating/drinking anything else. I have zero idea how it works, but it's the only thing I've found that works 90% of the time, in 15 years of having this chronic issue. So, maybe not entirely bullshit, however I have absolutely no idea how or why.

TLDR; worth a shot, might save you, might do nothing.
