Probiotics, live microorganisms that can be consumed through food or supplements, are often considered beneficial for gut health. Research suggests they may also influence cholesterol levels, a key factor in heart health. While the exact mechanisms are still being studied, some probiotics have shown promise in helping to manage cholesterol by affecting how the body processes it.
How Do Probiotics Impact Cholesterol Levels?
Probiotics may influence cholesterol levels through several mechanisms:
- Binding with cholesterol: Certain probiotics can bind to cholesterol in the gut, reducing its absorption into the bloodstream.
- Breaking down bile: Probiotics can break down bile, which is made from cholesterol. This process uses cholesterol, lowering its levels.
- Producing short-chain fatty acids: Fermentation of fiber by probiotics in the colon results in compounds that inhibit cholesterol synthesis.
Which Probiotics Are Most Effective for Lowering Cholesterol?
While research is ongoing, some probiotic strains have shown more promise than others in lowering cholesterol. Lactobacillus and Bifidobacterium are among the most studied. Specific strains like Lactobacillus rhamnosus GG and Saccharomyces boulardii have demonstrated potential benefits, particularly in managing cholesterol and reducing the duration of infectious diarrhea.
What Does the Research Say About Probiotics and Cholesterol?
Studies suggest that probiotics can modestly reduce total and LDL ("bad") cholesterol levels. However, the effects can vary depending on the specific strains used, the dosage, and individual factors. More research is needed to fully understand the potential of probiotics in managing cholesterol and supporting heart health.
What Other Factors Affect Cholesterol Levels?
Besides probiotics, several other factors significantly impact cholesterol levels:
- Diet: Reducing saturated fat and cholesterol intake can lower LDL cholesterol. Replacing saturated fats with unsaturated fats, such as fish oils and corn, peanut, safflower, and soybean oils, is also beneficial.
- Weight Management: Maintaining a healthy weight can help lower LDL cholesterol and raise HDL ("good") cholesterol.
- Physical Activity: Regular exercise can improve cholesterol levels.
- Other Dietary Factors: Soluble fiber, found in oats, barley, legumes, and certain fruits, can lower LDL and total blood cholesterol levels. Soy foods, like tofu and soy milk, are also associated with decreased LDL and total blood cholesterol levels.

Can probiotics replace cholesterol-lowering medication?
Probiotics should not be considered a replacement for prescribed cholesterol-lowering medications like statins. While some probiotics may help lower cholesterol levels, their effect is generally modest. Individuals with high cholesterol should follow their healthcare provider’s recommendations, which may include medication, lifestyle changes, and dietary adjustments.
Are there any risks associated with taking probiotics?
Probiotics are generally considered safe for most people. However, individuals with compromised immune systems should exercise caution, as probiotics have been associated with bacteremia (bacterial infection of the blood) and fungemia (fungal infection of the blood) in rare cases. It’s always best to consult with a healthcare provider before starting any new supplement, especially if you have underlying health conditions.
How long does it take for probiotics to lower cholesterol?
The time it takes for probiotics to impact cholesterol levels can vary. Some studies have shown modest reductions in cholesterol within a few weeks, while others may take longer to show noticeable effects. Consistency is key, and it’s important to maintain a healthy diet and lifestyle in addition to taking probiotics.
In conclusion, while research indicates a potential link between probiotics and improved cholesterol levels, it’s essential to maintain a balanced approach to heart health. This includes a healthy diet, regular exercise, and, when necessary, medical interventions.
