Both apple pectin and acidophilus are good choices for gastrointestinal support, but they're even better when taken together. Swanson Acidophilus & Apple Pectin capsules contain 1 billion viable organisms and 300 mg of apple pectin for reliable supplementation. Your gut needs healthy bacteria like acidophilus to maintain a healthy balance of microflora and soluble fiber like pectin to maintain regularity and optimal digestive function. When consumed together as a supplement, pectin acts as a carrier for acidophilus, ensuring that the viable bacteria are delivered to the GI tract without being destroyed on the journey.
