What types of fiber supplements are available?

Fiber supplements can generally be categorized into two types: soluble and insoluble fiber.

1. Soluble Fiber

• Sources: Includes psyllium, inulin, and pectin (found in gels).
• Benefits: Helps regulate blood sugar levels and lower cholesterol. Often added to processed foods for its health benefits.

2. Insoluble Fiber

• Sources: Found in foods like celery and whole grain products.
• Benefits: Promotes movement through the digestive system, helping with regularity and preventing constipation.

According to Robert Lustig, both types of fiber are essential for health. While soluble fiber is commonly used in supplements, it’s important to include insoluble fiber as well to gain the full benefits of a fiber-rich diet. Whole, unprocessed foods are recommended for obtaining these fibers naturally 1.
