Fiber supplements
Ideally, daily fiber requirements are obtained solely from dietary sources, but this can be tough to accomplish. Research shows that fiber supplements are effective in treating constipation by increasing stool output. Psyllium husk, a source of soluble fiber, is the most effective and widely studied. Psyllium husk powder is a great addition to smoothies, yogurt bowls, or baked goods and an easy way to up your fiber intake.
