5 Benefits of Psyllium Husk


Psyllium Husk is a fibre used primarily as a laxative made of Plantago ovata seeds. It is grown around the world but most commonly in India.

Psyllium is comprised of 85% carbohydrates and the rest fat and protein. It is primarily insoluble fibre (non-digestible and water resistant) and the rest soluble fibre (easily absorbs water, expanding gel-like substance).

  1. Bowel habits

    Constipation can occur for many reasons such as stress, dehydration, eating habits and lack of exercise.

    The soluble portion of psyllium has a bulking effect by soaking up water in the gut creating a soft gelatinous mass for elimination. The insoluble fibre contributes to the bulk and peristalsis of the bowel movement.

    Whilst psyllium is known commonly for help in constipation, it is also used often in diarrhoea too as it has a very adaptive effect on bowel movements. This mechanism is less understood, but in the case of diarrhoea, psyllium absorbs water, regulates peristalsis and prolongs a transit. This may be because it blocks calcium ion channels and activates the NO-cGMP pathway which together helps to slow down peristalsis.

  2. Lowers blood glucose levels

    It is known that fibre is useful to balance insulin and blood glucose levels. Psyllium acts in the gastrointestinal tract to slow the carbohydrate absorption, reducing insulin release and postprandial glucose levels.

    Psyllium has been observed to reduce fasting blood glucose levels, insulin spikes, glucose absorption and HbA1C levels.

  3. Lowers cholesterol

    Fibre is also useful for maintaining healthy cholesterol levels. Use of psyllium has been used to keep high levels under control.

    Cholesterol is necessary and important for many functions in the body, including hormones. High levels of LDL is generally considered bad where as HDL is good. Psyllium has been found in some studies to have reduced total Cholesterol and LDL.

    The benefits can also be attributed to the bile acid increase which is a primary elimination of blood cholesterol.

  4. May help weight management

    Psyllium husk may be useful in weight management as it increases feelings of fullness. It may work by delaying stomach emptying and carbohydrate absorption. Whilst this is a useful tool and some studies have show positive results, it’s use should be accompanied with a healthy diet and lifestyle.

  5. Prebiotic

    Types of fibres can act as prebiotics. Prebiotics are required for growth of probiotics and support their colony forming. A strong variety and content of beneficial bacteria contributes towards healthy digestion and an immune system.
