From the Guidelines
Psyllium husk is primarily used as a dietary fiber supplement to improve digestive health and relieve constipation, and it is recommended as a first-line therapy for chronic idiopathic constipation (CIC) due to its effectiveness in promoting regular bowel movements 1.
Key Uses of Psyllium Husk
- Relieving constipation by absorbing water in the intestines to form a gel-like substance that helps soften stool and promote regular bowel movements
- Lowering cholesterol levels, particularly LDL cholesterol, by forming a viscous gel in the digestive tract that slows digestion and nutrient absorption 1
- Regulating blood sugar and promoting feelings of fullness for weight management
Important Considerations
- The typical dosage for adults is 1-2 teaspoons (approximately 5-10 grams) mixed thoroughly with 8 ounces of water, taken 1-3 times daily
- When starting psyllium, it's best to begin with a lower dose and gradually increase to avoid gas and bloating
- Always drink plenty of water when taking psyllium, as it requires adequate fluid to work properly and prevent intestinal blockage
- People with certain digestive conditions, swallowing difficulties, or those taking medications should consult a healthcare provider before using psyllium, as it may interact with medication absorption
Safety in Special Populations
- Psyllium husk is safe to administer in pregnancy due to the lack of systemic absorption, and it can help promote regular bowel movements and prevent constipation 1
- However, excessive fiber and osmotic laxatives like lactulose can cause maternal bloating, and stimulant laxatives should be avoided due to conflicting safety data.
From the Research
What is Psyllium Husk
Psyllium husk is a soluble fiber derived from the seeds of the Plantago ovata plant. It is commonly used as a dietary supplement to promote digestive health and lower cholesterol levels.
Uses of Psyllium Husk
- Lowering cholesterol levels: Psyllium husk has been shown to reduce serum total and LDL-cholesterol concentrations in individuals with hypercholesterolemia 2, 3, 4, 5.
- Managing hypercholesterolemia: Psyllium husk can be used as an adjunct to diet therapy to manage mild to moderate hypercholesterolemia 2, 3, 4.
- Reducing the risk of coronary heart disease: The US Food and Drug Administration has authorized the use of health claims on food products containing soluble fiber from psyllium, stating that they are associated with a decreased risk of coronary heart disease 4.
- Relieving constipation: Psyllium husk can help relieve constipation by increasing stool bulk and softening stool 6.
- Improving lipid profiles: Psyllium husk has been shown to reduce non-HDL cholesterol and apolipoprotein B levels, which are alternative lipid targets for cardiovascular disease risk reduction 5.
Benefits and Side Effects
- Psyllium husk is generally well-tolerated, but may cause gastrointestinal side effects such as bloating, gas, and abdominal discomfort 2, 6.
- The benefits of psyllium husk include its ability to lower cholesterol levels, manage hypercholesterolemia, and reduce the risk of coronary heart disease 2, 3, 4, 5.
- Compliance with psyllium husk therapy may be optimized with adequate patient counseling and monitoring of gastrointestinal symptoms 6.
