You’re not looking at the right thing. Swanson’s may sell gentle digest but Gental DIgest is not their brand of probiotic and can be purchased elsewhere. Go to SwansonVitamins.com – Swanson’s has two probiotic supplements that I’ve used:
Stephen Langer’s Ultimate 15 Strain Probiotic with FOS. It’s $14.99 for 60 capsules and in addition to 15 strains of probiotics has FOS (prebiotic) and trace minerals.
Swanson Ultra Soil Based Organisms. It’s $9.99 for 90 capsules, has 4 digestive enzymes, wheat grass, oat grass, barley juice, a vegetable concentrate blend, trace minerals and 15 strains of probiotics.
The more strains of probitoics the better. Different probiotics have different functions and you want a diverse population the gut.
