One thing that people lack on the keto diet is fiber. Since many fiber sources also come with high carbohydrates, keto dieters miss out on this important nutrient. That's why you need a good keto diet fiber supplement. It's also important to still consume fibrous vegetables on the diet. There are a few signs of fiber deficiency. You could feel bloated or be constipated if your fiber is too low. You may become hungry directly after eating. Low fiber can also increase weight gain, lead to high cholesterol, and high blood pressure. Fiber will bulk up stool, making it firmer if it's too loose. It will also help if your stool is too hard, by making it easier to pass. This is a common concern on keto diets. Let's take a look at the different types of keto diet fiber supplements.

Psyllium fiber breaks down the stomach to become a food source for good bacteria that live in your stomach. It can be used to treat diverticulosis, irritable bowel syndrome, and constipation. If you have high cholesterol, psyllium fiber can help lower it by 10-15%. This makes psyllium fiber one of the best keto diet fiber supplements
Methylcellulose Fiber
When talking about the best keto diet fiber supplements you have to mention methylcellulose fiber. This fiber is non-allergenic, non-fermentable and can be taken every day. Methylcellulose is created from the cell wall of plants. It absorbs water to create a softer stool and is no absorbed by the intestinal tract. It is used to treat diarrhea, IBS, diverticulosis, and constipation. Since it doesn't ferment, it's less likely to cause gas than other types of fiber. It is absorbed by cold water and forms a gel, and should be taken 2 hours before or after taking other medications.
Polycarbophil Fiber
Polycarbophil is created by plants and is not absorbed by the body. It absorbs water in the intestinal tract to create a bulkier and softer stool. It's a type of fiber that is less likely to cause bloating. Polycarbophil can be used in the long term. It may be used to treat constipation, IBS, and diverticulosis. If you have trouble swallowing you may not want to take this type of fiber. It should be taken about 2 hours before or after taking other medications, in order to avoid interfering with absorption.
