Psyllium Husk: Benefits, Side Effects + more – The Best Full Guide

Psyllium husk is a popular dietary fiber supplement, which is a whole food from natural sources, lauded for its many health benefits. Particularly in improving digestion and promoting gut health.

In this comprehensive guide, we’ll discuss everything you need to know about this functional food, its benefits, and potential side effects, and cover some frequently asked questions.

What is Psyllium Husk

So, what’s psyllium husk, anyway? It is a natural, soluble fiber derived from the seeds of the Plantago ovata plant, native to India and Pakistan. 1

It has a long history of use in traditional medicine for its digestive benefits, and in modern times, it’s often used as a dietary supplement.

Is Psyllium Husk a Grain?

Although the husk comes from the seeds of the Plantago ovata plant, it is not considered a grain. It is a form of dietary fiber that is not part of the grain family.

Is Psyllium Husk Gluten Free?

Yes, it is gluten-free, making it suitable for those with gluten sensitivity or celiac disease.

How is Psyllium Husk Made?

The process of processing, or making the husks involves harvesting the seeds, removing the outer husk, and then milling it into a fine powder or processing it into a whole husk form.

What Psyllium Husk is used for?

The husk is used primarily as a dietary fiber supplement, providing a range of health benefits including improved digestion, regular bowel movements, and overall gut health.

It is also becoming more widely used in a range of plant-based recipes as it has some very good thickening properties. We use it quite frequently in our cooking, and along with Sea Moss, it is a key part of the binding for our Raw Red Velvet Cake. This way, it fits into our lives as a functional food that we love.

It is also a key ingredient in another product we love, Ultimate Fibre. The Chocolate flavour is my go-to choice in this range.

As a type of fiber it can also be found in many different manufactured food products, such as cereal, granola bars, and various supplements.

Is Psyllium Husk Good for You?

It is generally considered good for you due to its high soluble fiber content and various health benefits, such as lowering cholesterol levels, aiding in weight loss, relieving diarrhea, reducing inflammation, and promoting regular digestion. 2 3 4 5 6 7 8

This is by no means a complete list, as the benefits of many foods when closely assessed in detail have broad and varying roles to play in our lives. We will take a look at a few more benefits that I find particularly interesting with psyllium husk a little later.

Which Psyllium Husk is Best?

The best psyllium husk is one that is 100% pure and free of artificial additives, colours, or flavours. It is also essential to choose a product that has been tested for quality and purity by a reputable third-party laboratory.

What is the Difference Between Psyllium Husk Powder and Whole Psyllium Husk?

The biggest difference between the powder and the whole form of psyllium husk is that the powder is normally a finely ground version of the whole psyllium husk. This makes it easier to mix with liquids and incorporate into recipes.

The whole psyllium husk is coarser in texture, but both forms provide the same health benefits.

Regardless of the form, it is always worth reviewing the ingredients and Nutritional Information Panel (NIP) to see what else may be in the product.

An example of a NIP is shown below. When complete and constructed from reliable data points, like this one, it makes understanding what the product contains so much easier.

What Happens when you Start Taking Psyllium Husk?

When you start taking psyllium husk, you may initially experience increased gas and bloating as your body adjusts to the additional fiber.

However, these side effects should subside as your digestive system gets used to the increased fiber intake. We will look at the topic of side effects later in this article.

Top 9 Benefits of Psyllium Husk

As touched upon before, some of the benefits of having soluble fibre in your diet, like psyllium husk, can play a key role in supporting a well-rounded approach to health through good eating habits.

So, who should take psyllium husk? Doctors and Nutritionists may suggest that if the following are points of concern, then this natural product could be just the thing.

It has been researched for its effectiveness in key areas and relied upon by many for years for the following benefits including:

  1. Lowering cholesterol
  2. Having positive impacts on LDL and HDL 9 10
  3. Potentially aiding in weight loss
  4. Improving satiety 11
  5. Helping relieve diarrhea
  6. Reducing inflammation
  7. Helping to regulate digestion and prevent constipation
  8. Having a significant effect on the intestinal microbiota composition of constipated participants, and 12
  9. Normalising stool form in participants with Irritable Bowel Syndrome (IBS). 13

Let’s take a closer look at a few of these.

Lowers Cholesterol

Is it true? Can psyllium husk lower cholesterol? Being a rich source of soluble fiber, this has been shown in studies to help lower cholesterol levels.

When soluble fiber is consumed, it forms a gel-like substance in the digestive system, binding to cholesterol and bile acids, which are then excreted from the body. This process reduces the overall amount of cholesterol in the bloodstream, thereby lowering cholesterol levels and lending to the promotion of better heart health.

Psyllium and the Impact on LDL and HDL

It primarily impacts LDL cholesterol, which is known as the “bad” cholesterol. As touched upon in the section above, it helps reduce LDL levels by binding to cholesterol and facilitating its removal from the body.

On the other hand, HDL cholesterol, known as the “good” cholesterol, is generally not significantly affected by the intake.

By lowering LDL levels, the ratio of HDL to total cholesterol can improve, which is a positive indicator of cardiovascular health.

May Aid in Weight Loss

It can aid in weight loss through several related mechanisms. One of which is by increasing feelings of fullness and reducing hunger, also known as satiety.

The soluble fiber in psyllium husk absorbs water and expands in the stomach, which slows down the digestion process and helps regulate appetite.

Additionally, the husk can help stabilise blood sugar levels, which can further contribute to weight loss by reducing cravings and promoting better overall metabolic health.

Can Help Relieve Diarrhea

It can help relieve diarrhea by absorbing excess water in the intestines, thereby solidifying the stool and promoting regular bowel movements.

Its gel-forming properties also help protect the intestinal lining and slow down the passage of food through the digestive tract, allowing for better nutrient absorption and reduced frequency of diarrhea episodes.

Has the Potential to Reduce Inflammation

Psyllium may help reduce inflammation in the gut by promoting a healthy balance of intestinal bacteria. The soluble fiber in the husk acts as a prebiotic, nourishing beneficial bacteria in the gut and promoting a diverse microbial environment.

This, in turn, can lead to the production of anti-inflammatory compounds and a reduction in the overall inflammation within the gastrointestinal tract. 14

Helps Regulate Digestion and Prevent Constipation

It is effective in regulating digestion and preventing constipation due to its high fiber content.

As touched upon in the section where the benefits of reducing diarrhea by adding bulk to the stool were covered, it plays a balancing function with constipation also. It does this by making stools softer and easier to pass through the digestive system.

Moreover, its water-absorbing properties help retain moisture in the stool, further facilitating bowel movements and reducing the risk of constipation.

Effect on the Intestinal Microbiota Composition

Psyllium has a positive effect on intestinal microbiota composition, as it acts as a prebiotic, supporting the growth of beneficial bacteria in the gut.

By providing a food source for these beneficial microbes, this husk promotes a diverse and healthy gut microbiome, which is essential for optimal digestive health and overall well-being.

What is not commonly known is that it can also have a positive effect on the composition of the intestinal microbiota.

The intestinal microbiota is a collection of microorganisms that live in our intestines, including bacteria, viruses, and fungi. These microorganisms help with digestion, nutrient absorption, and immune system function.

Research has shown that the use of psyllium husk can lead to an increase in beneficial bacteria, such as Lactobacillus and Bifidobacterium, which can help maintain a healthy balance in the gut microbiota.

Studies have also found that it can help reduce the levels of harmful bacteria, such as Clostridium and Escherichia coli, which can cause infections and inflammation in the gut.

By promoting a healthier balance of bacteria in the gut, this husk can help prevent and treat various gastrointestinal disorders, such as inflammatory bowel disease and IBS.

It is important to note that the effects of it on the intestinal microbiota may vary depending on the individual’s diet and lifestyle habits. However, incorporating psyllium husk into a healthy diet can be a simple and effective way to improve gut health and promote overall well-being.

Normalises Stool Form in IBS

As mentioned earlier, it can help normalise stool form in individuals with IBS by adding bulk and moisture to the stool.

This can alleviate both constipation and diarrhea, which are common symptoms of IBS. The fiber in the husk helps regulate bowel movements and may also reduce abdominal pain and bloating associated with IBS.

Fasting Friendly

So, you’re fasting, and you want to know ‘Will psyllium husk break my fast?’

Short answer, “No”. Long Answer, “No”, but with context.

As it is low in calories and does not contain any significant amount of protein, fat, or carbohydrates, it is unlikely to break your fast.

However, it is always best to consult with your Dietitian or trusted Doctor before making any changes to your diet or fasting regimen.


Some alternatives to psyllium husk include inulin, flaxseeds, chia seeds, and glucomannan. These are all-natural sources of dietary fiber that can provide similar benefits.
