Note: Speak with your doctor before beginning any dietary supplementation. Black psyllium: This supplement is made from the seed of a plant, and adds bulk to stools, aiding with constipation. Blond psyllium: The husks of the seed from this herb absorb water, forming a large mass, which can stimulate the bowels to move. Fiber: Fiber supplements can be taken in pill or powder form as a long-term aid to constipation issues. Laxatives: Laxatives can be great for quick relief from constipation, but should not be used long term as they can be dehydrating. Magnesium: Magnesium helps to neutralize stomach acid, as well as lubricate the gastrointestinal tract, acting as a laxative. Can lead to electrolyte imbalance or other serious side effects. Stool softeners: Gentler than a laxative, these can be taken for a longer period of time.
