Our take on the 21st Century Psyllium Fiber Capsules

21st Century Psyllium Fiber Capsules deliver 2 grams of soluble fiber per serving to support digestive health and, as part of a low-saturated-fat diet, heart health. The capsules are gluten-free, non-GMO, and kosher, but the serving is large at 5 capsules, and some users find them hard to swallow. Compared with psyllium powders, capsules are more convenient and portable but cost more per serving and require taking several pills. Reviewers appreciate the digestive benefits but note the pill size and the need to drink plenty of water.
