Psyllium husk or Isabgol is commonly used as a dietary supplement to relieve constipation, promote bowel regularity, and support overall digestive health. It is also known as Isabgol ki bhusi in India. It is available in various forms, including whole husks, powder, and capsules, and is typically mixed with water or other fluids before consumption.
What is Isabgol made of?
Psyllium husk, or Ispaghula, derives from the husks of Plantago octava seeds. It is a natural, water-soluble substance that is well-known for its gel forming properties. Historically, India and China have been using ispaghula for treating high blood pressure, bladder issues, and skin irritation.
Who should consume Isabgol?
Isabgol’s common usage is to treat constipation by increasing water retention in the intestine, making it easier to pass stool and changing the gut environment. Psyllium supplementation effectively increased stool water and significantly impacted gut microbiota, particularly in constipated patients.

Garima Dev Verman, Dietitian and Certified Diabetic Educator, Delhi says, “Psyllium husk is beneficial for individuals who struggle with constipation or irregular bowel movements, as it promotes healthy digestion and regularity. It can also be beneficial for those managing high cholesterol levels, as it may help lower LDL cholesterol levels.” The following people can benefit from Isabgol ki bhusi or psyllium husk:
- Individuals with constipation
- People with irritable bowel syndrome (IBS)
- Individuals with diarrhoea
- Those managing high cholesterol
- People managing blood sugar levels
- Individuals wanting to increase fibre intake
- Anyone looking to improve gut health
When is the best time to drink Isabgol?
Garima Dev Verman says, “It is preferable to take Isabgol with lukewarm water shortly before bed or first thing in the morning on an empty stomach. It can effectively regulate digestion and promote bowel movements as a result.”
Isabgol side effects
Isabgol is generally a safe supplement. However, like any other medication or supplement, it can have potential side effects. Here are some of the side effects of Isabgol, especially if we take it improperly or in excessive amounts:
Gastrointestinal Issues: The most common side effects of Isabgol include bloating, gas, and abdominal discomfort. This is because Isabgol absorbs water and expands in the digestive tract, which can lead to these symptoms, especially if not taken with sufficient water.
Reduced Nutrient Absorption: Isabgol’s ability to absorb water and bulk up in the gut can potentially reduce the absorption of nutrients from food, especially if used excessively or over a long period.
Electrolyte Imbalance: If taken in excessive amounts, Isabgol can lead to electrolyte imbalances, particularly potassium imbalance, which may cause symptoms such as weakness, fatigue, irregular heartbeat, or muscle cramps.
Interference with Medications: Isabgol can potentially interfere with the absorption of certain medications if taken at the same time. It’s important to take medications at least 1-2 hours before or after Isabgol to avoid this interaction.
Obstruction of the Oesophagus or Intestines: In rare cases, especially if not taken with enough water or if the dose is too large, Isabgol can swell and cause a blockage in the oesophagus or intestines. This is more likely if you have a history of swallowing difficulties or gastrointestinal strictures.
Allergic Reactions: Some individuals may experience allergic reactions to Isabgol, although this is rare. Symptoms of an allergic reaction may include itching, rash, swelling (especially of the face/tongue/throat), severe dizziness, or trouble breathing.
Before starting to use psyllium husk or any supplement, it’s advisable to consult with a healthcare provider. Especially, if you have any existing medical conditions or are taking medications. They can provide guidance on the appropriate dosage and ensure it is suitable for your specific health needs.
