Can Fibre Lower Cholesterol? What You Need to Know About Fibre Supplements and Heart Health

Did you know that fibre can do more than just help keep your bowel movements regular? Research is showing that certain types of dietary fibre—like psyllium husk—may also help lower cholesterol levels and support heart health.

In this blog, we’ll explore how fibre works, what types are available, and how you can safely use fibre supplements as part of your overall wellness plan.

🌾 What Is Fibre and Why Is It Important?

Fibre is a type of carbohydrate that your body can’t digest. It plays a key role in digestive health, but its benefits don’t stop there.

There are two main types of fibre:

• Soluble fibre – dissolves in water to form a gel-like substance (e.g., psyllium husk, oats, inulin)

• Insoluble fibre – adds bulk to the stool and helps keep things moving (e.g., wheat bran)

Soluble fibre, especially psyllium, has been studied for its potential to help reduce:

• Total cholesterol

• "Bad" LDL cholesterol

• Non-HDL cholesterol

• Apolipoprotein B (a key marker of heart disease risk)

❤️ Fibre and Heart Health: What the Research Says

High cholesterol is one of the main risk factors for cardiovascular disease, which includes heart attacks and strokes. According to the Australian Institute of Health and Welfare, about 1 in 10 Australian adults have been told they have high cholesterol—a number that's increasing every year.

The good news? Fibre supplements like psyllium husk can help!

📊 What the Studies Show:

• Psyllium reduced total cholesterol by 6.5% and LDL ("bad") cholesterol by 7.8% in just 3 months.

• Triglycerides (another type of fat in your blood) also dropped by 12.7% over 6 months.

• These results were seen without any cholesterol-lowering medication.

Even better, combining psyllium with statins (cholesterol-lowering medicines) can make statins work even better—sometimes giving results similar to doubling the statin dose, but with fewer side effects.

💪 Other Health Benefits of Fibre

Besides supporting heart health, fibre may also:

• Aid weight loss: A meta-analysis showed that people lost about 2kg and 2cm from their waist by taking psyllium before meals.

• Improve gut health: Fibre helps feed good bacteria in the gut, which support digestion and immunity.

• Stabilise blood sugar: Soluble fibre slows down the absorption of sugar, which helps control blood glucose levels.

• Manage bowel conditions: Fibre is recommended for constipation, irritable bowel syndrome (IBS), ulcerative colitis, and more.
