Keto Fiber Supplement

7 Best Keto Fiber Supplements

Getting enough Fiber on the keto diet is extremely important.

What exactly is fiber? Why is it important on the keto diet?

Let me explain..

Fiber is a complex carbohydrate that is made of sugar. However, fiber does not raise insulin like sugar does. This is because fiber is not broken down into individual sugars and provides little or no energy. Your body does not possess the enzymes necessary to break the bonds of fiber.


Fiber remains intact as it travels through the body in which it is broken down by bacteria. These bacteria in return produce nourishment to your body creating a symbiotic relationship.


There are many different types of fiber. Despite being labeled as “ fiber,” many types are not fibrous. Some are more like gelatin. How do you get enough fiber? By taking a keto friendly fiber supplement and adding enough fruits and vegetables.


The two main types fiber for the keto diet are:

Soluble Fiber- This fiber is soluble in water. It forms a gel-like substance when mixed with water. Soluble fiber is found in oats, oatmeal, barley, fruit, and veggies.

Insoluble fiber, – Insoluble fiber, does not dissolve in water. When consumed, fiber passes through the digestive system mostly intact therefore not raising insulin.


Fiber has many jobs such as softening stools, balancing pH and absorbing toxins. Even more interesting is that fiber may also promote weight loss and is why a ketogenic diet is so effective. When you eliminate refined, processed carbohydrates, you also change gut microbiome, which is believed also to help weight loss.

Another disrupter of gut microbiome is artificial sweeteners. That is for a different post though!

The Benefits of Fiber on the keto diet 

#1-Satiety  – Consume soluble fiber found in nuts, seeds, and fibrous vegetables is very filling.

#2– Reduced Cholesterol- Yup, adding fiber and certain fiber supplements can lower cholesterol levels.  [6]

 #3-Mood Stability– Dietary fiber intake from vegetables and fruits was significantly correlated with reduced depressive symptoms. [4]

#4- Gut Health-  Fiber helps balance  Microbiome (fancy way of saying gut health)  – Studies of lean and obese mice suggest that the gut microbiota ( fancy word for saying Microbiome)  affects energy balance by influencing the efficiency of calorie use from the diet, and how this energy is utilized and stored. [7]

#5- Lower risk for Disease : People with  high fiber intakes have a lower risk for developing coronary heart disease, stroke, hypertension, diabetes, obesity, and certain gastrointestinal disorders [1] A significantly lower risk of 9% was seen for both CVD and CHD with every additional 7 g/day of total fiber consumed. [2]

#6 Weight Loss– Epidemiologic support that dietary fiber intake prevents obesity is healthy. Fiber intake was correlated with lower body weight and body fat. A high level of dietary fiber consumption from fiber supplements has been associated with a 30% reduction in the risk of gaining weight.  [5]

This is one of the reasons why populations that eat traditional foods, rich in high-fiber foods, are slim. You will also find that these slim populations don’t snack on low-fat 100 calorie packs or drink reduce fat milk!


Fiber on a Ketogenic Diet

It’s imperative to eat vegetables when going on a Keto diet. Carbohydrate restriction reduces your intake of health high-carbohydrate foods, which contain beneficial “food” for good gut bacteria.

If you have difficulties adding enough fruits and veggies and keeping your carbs under 50- try a fiber supplement. An isolated fiber supplement is not the same as getting fiber from whole foods. You must take this into consideration when choosing a keto fiber supplement. Not all are effective. 

From an evidence-based approach, I have listed the top three fiber supplements. Studies show that when it comes to fiber supplements, only soluble non fermenting, gel-forming fiber has been proven to provide all health benefits [5]
