Most supplements do not work; This one does

Psyllium husk, or isabgol, is gaining global attention as a gut-health staple. Studies say its fibre benefits extend to cholesterol, blood sugar and bowel health when taken safely with enough water.

In Short

• Psyllium forms a gel that slows digestion and bulks up stool
• Doctors say it can support poor fibre intake and irregular bowels
• Studies linked supplementation with lower LDL cholesterol and better blood sugar

Psyllium husk, or isabgol, is suddenly the world's favourite gut fix. It was our parents and grandparents go-to ritual long before wellness influencers and trends like fibre maxxing entered the conversation on social media platforms.

While psyllium husk was always quietly lined on the shelves of Indian pharmacies, the global demand for this supplement is now booming. The psyllium husk market size was valued at USD 1.77 billion in 2025.

It’s a plant-based soluble fibre derived from the seeds of the Plantago ovata plant, and the crop grows predominantly in Gujarat and Rajasthan. But modern Indians continue to eat some of the most fibre-deficient diets in the world and are also shifting away from coarse grains and lentils toward ultra-processed foods.

Psyllium is a very good source of fibre and can help people who often fail to meet their fibre needs. “Consumption of psyllium can help bridge the gap in individuals with poor dietary intake, irregular bowel habits and sedentary lifestyles," said Fiona Sampat, Clinical Dietitian, Kokilaben Dhirubhai Ambani Hospital, Mumbai.

This is not it; it offers multiple health benefits supported by solid scientific evidence.

BENEFITS OF PSYLLIUM HUSK:

Psyllium husk works by turning into a thick gel in the gut. This in turn slows down digestion, adds bulk to stool and is known to improve good bacteria in the gut. It also reduces gut inflammation, is beneficial for people with irritable bowel syndrome (IBS), and is also effective in treating both constipation and diarrhoea.

“Gut bacteria ferment some amount of psyllium, which produces short-chain fatty acids that promote healthy digestive function, nourish and maintain the intestinal lining and stimulate flourishing of beneficial flora in the digestive tract," explained Dr Ankur Jain, senior gastroenterologist at Max Hospital, Dwarka, Delhi. It immensely helps manage inflammatory conditions, he added.

It is also known to help decrease certain disease markers. A meta-analysis of 8 controlled clinical trials highlighted that psyllium husk lowered LDL cholesterol levels – "Psyllium supplementation significantly lowered serum total and cholesterol concentrations in subjects consuming a low-fat diet.”

According to another study published in Springer Nature, type 2 diabetic patients who took 10.5 g of psyllium daily for just eight weeks saw their fasting blood sugar drop from 163 to 119 mg/dl and insulin resistance cut nearly in half without changing much about their diet or lifestyle.

Also, dietary fibre intake is associated with a low risk of colorectal cancer. It is also known to aid with weight management because it keeps you fuller for longer.

HOW MUCH, HOW OFTEN, HOW SAFE?

In general, psyllium husk is a safe and useful addition to the diet when taken in appropriate amounts along with enough water, according to Dr Jain.

While there is no standardised dosage, “for most adults, 1–2 teaspoons (5–10 grams) once or twice a day is sufficient. It must always be taken with a full glass of water, at least 250–300 ml," he said.

Without enough liquid, the husk swells in the throat or food pipe and can cause severe bloating and, in some cases, even choking.

Dr Jain explained that “people with fluid restrictions, difficulty swallowing or known gastrointestinal narrowing should consult a doctor before starting it.”
