How to choose a gut health supplement
The gut health products on this shelf are probiotic capsules, some with prebiotic fiber or digestive enzymes added, and a psyllium fiber drink. Probiotics are judged by the strains and the number of live cultures (CFU) the brand publishes; fiber drinks by the type and amount of fiber per serving.
All three stores open on refill plans, so read the order summary before paying and keep the brand's cancellation instructions. Most only refund unopened bottles. Give any new product a few weeks, and talk to your doctor if you have a digestive condition.
What to look for
- Strains and CFU, or fiber type and amount, per serving
- How long one bottle lasts at the brand's dose
- Cost per day on the pack you plan to buy
- Subscription, cancellation and return terms
