Psyllium husk is a soluble fiber promoting regularity and digestive health by regulating stool water content.
Psyllium husk is a soluble fiber derived from the Plantago ovata plant, widely used for its ability to promote digestive health. It effectively regulates bowel movements by increasing stool bulk and modulating water content, providing relief from both constipation and diarrhea. Furthermore, it can contribute to lowering cholesterol and stabilizing blood sugar levels. While generally safe, common side effects include bloating and gas. A critical precaution is to consume psyllium husk with adequate water to avoid the rare but serious risk of esophageal obstruction. Dosage should be individualized based on tolerance and health goals.
Key Information
Inside Body Harmful Score
Common Dosage
5-10 grams daily, divided into multiple doses, taken with plenty of water.
Source Type
natural
Production Process
Psyllium husk is derived from the seeds of the Plantago ovata plant. The seeds are harvested, and the husk is separated from the seed through milling and sieving processes. The husk is then typically dried and ground into a powder for consumption.

Inside BodyPotential Benefits
Digestive regularity promotes consistent and predictable bowel movements, preventing constipation, diarrhea, bloating, and gas. This benefit supports overall gut health by maintaining a balanced gut microbiome and efficient waste elimination.
This benefit lowers total, LDL cholesterol, and triglycerides while potentially raising HDL cholesterol, promoting cardiovascular health. It achieves this through multiple mechanisms affecting absorption, excretion, and synthesis of cholesterol.
Blood sugar control maintains blood glucose levels within a healthy range, preventing hyperglycemia and hypoglycemia. This involves insulin regulation, glucose uptake, and liver glucose production, crucial for preventing conditions like type 2 diabetes.
Psyllium husk, a soluble fiber, alleviates constipation by absorbing water, bulking stool, and facilitating easier bowel movements. It increases stool frequency and reduces straining.
Psyllium husk relieves diarrhea by absorbing excess water in the stool, increasing its bulk and solidifying its consistency. This helps to normalize bowel movements and reduce diarrhea frequency.
Psyllium husk promotes satiety by absorbing water in the gut, potentially reducing calorie intake and aiding weight management. It increases stool bulk, contributing to a feeling of fullness.
Possible Side Effects
Bloating is a feeling of abdominal fullness or distension, often caused by gas or underlying gastrointestinal issues. It is commonly linked to diet, IBS, or hormonal changes, and while usually benign, persistent or severe cases warrant investigation.
Gas is the presence of excess air in the digestive system, causing bloating, burping, and flatulence. It is often caused by diet or swallowing air, but can also be related to underlying gastrointestinal conditions.
Allergic reactions are hypersensitivity responses to allergens, ranging from mild skin irritation to life-threatening anaphylaxis. Symptoms vary widely and are caused by an immune response.
Allergic reactions are adverse immune responses to normally harmless substances, ranging from mild skin irritation to severe anaphylaxis. Symptoms can include skin issues, swelling, breathing difficulties, and anaphylaxis requires immediate epinephrine injection.
Psyllium husk supplementation can lead to bloating and increased gas production, especially when starting use. This is due to fermentation by gut bacteria.
Abdominal cramping involves muscle contractions or spasms in the abdomen, potentially worsened by dehydration. Symptoms include squeezing sensations, bloating, and altered bowel habits.
Esophageal obstruction is a life-threatening condition occurring when psyllium husk swells in the esophagus due to insufficient water intake, leading to blockage and potentially asphyxiation.
