Welcome to HealingWell!
Many of us on this board are on, or have tried, Digestive Advantage (aka DA). I'd have to say about
1/2 of us like it and believes that it works.
DA is pretty much a blend of "good bacteria" that will help your digestion. It is totally safe and has no side affects (unless you're allergic to something in it). It is worth a shot. If you try it take 2 pills a day for the first few days, then go down to 1 a day. If you don't see any results in a 2-3 weeks you can bump up the dose to 2 pills a day.
I've been on it for months... I love it. It has helped me stay regular and helps cut down the bloating.
Good luck! Hopefully others will be around soon to share their experience.
