Why it made the stack
Key takeaways.
Most American adults eat far less fiber than the 25 to 34 g a day the Dietary Guidelines recommend. 6 g closes part of that gap.
Psyllium is the best-studied fiber supplement, especially for regularity.
Momentous says start with 1 scoop for the first 1 to 2 weeks to avoid bloating.
