Take control of your cholesterol levels in 2024 with the ultimate selection of fiber supplements that are proven to lower high cholesterol.


If you worry about high cholesterol, you know changing what you eat can help lower it. One easy change is eating more fiber. Research shows fiber can lower “bad” cholesterol levels. Fiber supplements make it simple to increase daily fiber. But there are many options. It’s important to know which kinds of fiber work best and how much you need.

This article will talk about the best fiber supplements for high cholesterol. It will explain the difference between soluble and insoluble fiber and how much you need. You’ll learn how these supplements fit into a plan to lower cholesterol with diet and lifestyle. This guide will help you choose a quality fiber supplement to lower your cholesterol naturally.

How Fiber Supplements Help Lower Cholesterol

Fiber supplements, such as psyllium husk or oat bran, can effectively help lower high cholesterol levels. Fiber binds to bile acids, which are made from cholesterol, in the digestive tract. This prevents the bile acids from being reabsorbed into the bloodstream, forcing the liver to tap into cholesterol stores to produce more bile acids. Over time, this process helps lower cholesterol levels.

Reducing LDL Cholesterol (low-density lipoprotein)

The most significant impact of fiber supplements is lowering low-density lipoprotein (LDL) cholesterol, the “bad” cholesterol responsible for plaque buildup in arteries. Studies show that for every 1 gram of soluble fiber consumed daily, LDL cholesterol can drop by up to 2 percent. The recommended daily intake of fiber to help lower high cholesterol is 5 to 10 grams or more of soluble fiber per day from supplements.

Increasing HDL Cholesterol (High-density lipoprotein)

Fiber supplements may also slightly increase high-density lipoprotein (HDL) cholesterol, the “good” cholesterol that helps remove LDL cholesterol from arteries. Although the effect is modest, any increase in HDL is beneficial for heart health. Fiber supplements, as part of a balanced diet and exercise, can help raise HDL cholesterol by 3 to 5 percent for every 10 grams of soluble fiber added per day.

Improving Triglycerides

Fiber supplements may produce a small reduction in triglyceride levels, a type of fat found in the blood. High triglycerides also increase the risk of heart disease. Although fiber alone may not lower triglycerides sufficiently, when combined with weight loss, exercise, and limiting sugar and refined carbohydrates, it can help support a drop of 10 to 20 percent or more.

In summary, fiber supplements can positively impact cholesterol levels and heart health. However, they should be used as part of a comprehensive lifestyle approach that includes diet, exercise, weight management, and limiting unhealthy fats. When used appropriately and consistently, fiber supplements are a safe and natural strategy for managing high cholesterol and supporting long term cardiovascular wellness.

The Best Types of Fiber for Cholesterol Control

Soluble Fiber

Soluble fiber is excellent for lowering cholesterol levels. It absorbs water in the intestine to form a gel-like substance that binds to bile acids and helps remove them from the body. This forces the liver to convert more cholesterol into bile acids, thereby reducing cholesterol levels. Good sources of soluble fiber include oats, barley, beans, broccoli, and Brussels sprouts. Aim for 5 to 10 grams of soluble fiber per day.

Psyllium Husk

Psyllium husk is a great supplement option for increasing soluble fiber intake. Psyllium husk powder and capsules contain the fiber from the Plantago ovata plant seeds. Studies show psyllium husk can lower total and LDL cholesterol by 5 to 10 percent. For the best results, take 5 to 10 grams of psyllium husk powder or around 6 capsules daily, starting with a lower dose and increasing gradually to allow your body to adjust.


Beta-glucan is a type of soluble fiber found in oats and barley that is very effective for lowering cholesterol. Oat beta-glucan in particular has been shown to reduce total and LDL cholesterol by 5 to 10 percent. Look for oat bran, oatmeal, and oat flour with at least 3 grams of beta-glucan per serving. Barley and some types of mushrooms also contain beta-glucan. Aim for at least 3 grams of beta-glucan per day from these foods or from supplements.


Inulin is a starchy fiber found in foods like chicory root, Jerusalem artichoke, and bananas. Inulin powder and capsules provide an easy way to increase your inulin intake to help lower cholesterol. Research shows inulin may reduce LDL cholesterol by up to 10 percent. The typical dosage for cholesterol control is around 5 to 10 grams of inulin powder or 2 to 3 capsules with 2 to 3 grams of inulin two or three times per day. Start with a lower amount and increase slowly to minimize gas and bloating.

The bottom line is that increasing your intake of soluble fiber, especially psyllium husk, beta-glucan, and inulin, can have a significant impact on lowering your cholesterol levels in a natural way. When combined with a healthy diet and exercise, these supplements may help reduce your need for cholesterol-lowering medications. However, you should always talk to your doctor before making any changes to your medications or treatment plan.

Can you get fiber naturally from foods?

Most people in the U.S. take in much less fiber than they should. The best way to get it is from food, like a variety of fruits, vegetables, and grains. Some good sources of soluble fiber include:

  • Oatmeal and oat bran
  • Apples, citrus fruits, and strawberries
  • Beans, peas, and lentils
  • Barley
  • Rice bran

And some sources of insoluble fiber are:

  • Cereal brans
  • Whole grains, like barley
  • Whole-wheat breads, wheat cereals, and wheat bran
  • Vegetables like carrots, cabbage, beets, and cauliflower

Our Top Picks for Fiber Supplements to Reduce High Cholesterol

Psyllium Husk

Psyllium husk comes from the seeds of the Plantago ovata plant. It is a soluble fiber that forms a gel-like mass when mixed with water. Studies show psyllium husk can lower LDL (bad) cholesterol by 5-10% when taken regularly. Look for a product containing at least 5 grams of psyllium husk per serving and follow the directions on the packaging for the proper dosage. Start with a lower amount and increase slowly to allow your body to adjust to the extra fiber.


Beta-glucan is a type of soluble fiber found in oats and barley. Supplements containing at least 3 grams of beta-glucan per serving have been shown to lower LDL cholesterol by 5-10% when consumed daily. The gel formed during digestion helps block cholesterol absorption in the gut. Beta-glucan supplements are generally well tolerated, but may cause initial gastrointestinal upset in some people.


Glucomannan is a water-soluble fiber derived from the konjac root. Multiple studies show glucomannan supplements significantly reduce LDL cholesterol and other heart disease risk factors. A dosage of at least 4 grams per day is recommended for cholesterol lowering effects. Glucomannan expands in the stomach to create a gel, which helps you feel full and suppresses appetite. However, it may cause bloating, gas or diarrhea in some individuals.

Red Yeast Rice

Red yeast rice is made by fermenting rice with Monascus purpureus yeast. It contains compounds called monacolins that inhibit the production of cholesterol by the liver. Several studies found red yeast rice reduced LDL cholesterol by 22-33% in people with high cholesterol. A typical dosage providing 2.4 milligrams of monacolin K is recommended. However, red yeast rice may cause the same side effects as statin drugs, such as muscle pain. You should not take red yeast rice if you are already on statins or have liver disease.

In summary, the fiber supplements psyllium husk, beta-glucan and glucomannan as well as red yeast rice can help lower high cholesterol when taken as directed. However, you should always consult your doctor before adding any supplements to determine what options are best and safest based on your individual health needs.


As we have discussed, there are several effective fiber supplements that can help lower high cholesterol when combined with dietary and lifestyle changes. Focus on soluble fiber sources like psyllium, glucomannan, and oat bran, which can bind to cholesterol-rich bile acids and remove them from your body. Aim for 10-25 grams of fiber per day from food and supplements. Be sure to introduce fiber supplements gradually and stay hydrated. Consult your doctor to determine the right fiber supplements and dosages for your needs. Making smart fiber choices can positively impact your cholesterol levels and heart health over time.
