Psyllium Husk – Uses, Benefits and Side Effects

What is Psyllium Husk?

If you have ever taken Metamucil, Serutan, or Fiber Eze, you have taken psyllium husk. Maybe you didn’t realize it at the time, but now you are probably wondering “what is psyllium husk?” Psyllium is a plant that goes by several names including:

  • Plantago ovata Forssk
  • Ispaghula
  • Isapghol
  • White psyllium
  • Blond psyllium
  • Indian Plantago

The term “Plantago” is derived from the Latin word “planta” which means “sole of the foot.” This refers to the shape of psyllium leaves.

Psyllium means “flea” in Greek. This is about the shape, color, and size of the psyllium seed. Psyllium is native to Persia but is now grown primarily in India.

A psyllium seed has an outer shell which, when removed from the seed, is called psyllium husk.

Psyllium husk produces a thick mucilage, or gel when water is added to it. Psyllium husk can absorb up to fourteen times of its weight in water.

This gel is used in the health care industry as a medical treatment, in the food manufacturing industry as a thickener, a binder, and as a fiber additive.

It is also used in the agricultural industry as animal food and as a soil treatment to help prevent erosion.

The study reported that 87 percent of the children responded to treatment and suggests that psyllium husks, when combined with the proper diet, were an effective treatment for diarrhea. 

Another study tested the effect of psyllium husk on medically induced diarrhea. The participants in this study were seven men and two women ranging in age from 20 to 36.

They were given a placebo, psyllium, calcium polycarbophil (a laxative), and wheat bran at different times and the effects of these four treatments were measured.

Psyllium Husk For Weight Loss

Many people want to know how to take psyllium husk for weight loss.

According to the authors of the book titled “Integrative Weight Management: A Guide for Clinicians,” psyllium may help obese individuals lose weight because it causes a feeling of fullness after eating.

They mentioned a study in which four different diets were compared in overweight and obese adults.

The results of the study demonstrated that the individuals whose diets included psyllium husk lost weight as a result of their diets.

What Does Psyllium Husk Do?

Are you wondering “what does psyllium husk do?” Do you want to know why you should always drink water when taking psyllium husk? When psyllium husk comes into contact with water it swells up and forms a gelatinous mass.

This mass, as it travels through the digestive system, does interesting things. In people with constipation, the gelatinous mass helps to stimulate bowel movements and move waste through the intestines.

As it is moving waste along, it is also binding with bile acids which helps to reduce blood cholesterol levels.

In people with diarrhea, the gelatinous mass binds with matter in the digestive system which helps to reduce bowel movements, thereby alleviating diarrhea.

Since psyllium husk has been shown to decrease blood sugar and decrease blood pressure, you may be magnifying these effects if you take psyllium husk with medications for these health issues.

Also, if you are taking any herbal supplements that lower blood pressure (like fish oil, L-arginine or stinging nettle) or that lower blood sugar (like bitter melon, garlic, guar gum or Panax ginseng), you may want to limit your intake of psyllium husk.

Psyllium Husk Side Effects – Long Term

If you take higher doses of psyllium husk you may experience bloating, flatulence, diarrhea, gastrointestinal distress, constipation, or feelings of nausea. Taking too much psyllium husk can prevent fat-soluble vitamins and minerals from being absorbed.

Psyllium Husk Carbs

If you are confused about psyllium husk carbs, don’t be. Most psyllium husk supplement packages will say something like this on the nutrition label:

  • Total Carbohydrate – 4.5 g
  • Dietary Fiber – 4.5 g
  • Soluble Fiber – 3.5 g
  • Insoluble Fiber – 1 g

Notice that the grams of carbohydrate are equal to the grams of dietary fiber which is equivalent to 4.5 grams in this case.

These two numbers are equal because dietary fiber is a carbohydrate.

Although dietary fiber is a carbohydrate, it is the type of carbohydrate that the human body cannot digest.

That is why psyllium husk works – it passes through the body instead of being digested by the body. It lowers blood sugar instead of raising it.

So you don’t have to consider the carbs in psyllium husk if you are counting carbs.
