NutrimatchThe Top 10 Supplements to Improve Cholesterol
Key takeaways
- Nine supplements have strong evidence for improving cholesterol markers — one of the best-evidenced categories in supplement research.
- Different supplements target different markers: Berberine and Phytosterols lower LDL, Fish Oil reduces triglycerides, Niacin raises HDL. Several address all three simultaneously.
- Effects are most pronounced in people who already have elevated cholesterol; those with already-healthy levels tend to see smaller improvements.
High cholesterol affects a significant portion of adults and is a key risk factor for heart disease. Several supplements have strong, replicated evidence for improving cholesterol levels — lowering LDL ('bad' cholesterol), raising HDL ('good' cholesterol), or reducing triglycerides. This guide covers the best-evidenced options, ranked by research quality.
Why cholesterol supplements are worth understanding
Cholesterol management is one of the few areas where a supplement — berberine — has evidence approaching that of a low-dose pharmaceutical. Multiple trials show that berberine reduces LDL cholesterol by 20–30% in some populations, which is comparable to the effect of low-dose statins. This is unusual in the supplement world, where most compounds produce effects far below what medication achieves.
Beyond berberine, several other compounds have meaningful evidence for improving cholesterol markers, though the effects are more modest. Understanding which markers each supplement targets is important, because not all cholesterol interventions are equivalent.
Understanding the different markers
LDL ("bad" cholesterol) is the primary target for cardiovascular risk reduction. Berberine and plant sterols have the strongest evidence for reducing LDL. Red yeast rice also works — it contains naturally occurring lovastatin — but carries the same risk profile as the pharmaceutical statin and requires the same monitoring.
HDL ("good" cholesterol) is harder to raise with supplements. Fish oil and exercise are the most evidence-based approaches. Most supplements that claim to raise HDL have limited data.
Triglycerides respond well to fish oil at doses of 2–4 g EPA+DHA daily. This is one of the strongest and most consistent findings in supplement research. Berberine also has evidence for triglyceride reduction.
Total cholesterol is less clinically useful as a target than the individual fractions. A product that claims to "improve cholesterol" without specifying which marker is usually not worth taking seriously.
The statin question
If your doctor has recommended a statin, supplements are generally not a substitute — statins have evidence from large outcome trials showing reductions in heart attacks and strokes, not just improvements in blood markers. Supplements like berberine improve the same markers but have not been tested in the same large outcome trials.
Supplements are most appropriate for people with mildly elevated cholesterol who do not yet meet the threshold for medication, or as additions to statin therapy (with medical guidance) for people who need additional lipid lowering.
Red yeast rice: a special case
Red yeast rice contains monacolin K, which is chemically identical to lovastatin. It can be effective, but it carries the same risks as a pharmaceutical statin — including the potential for muscle pain, liver enzyme elevation, and drug interactions. Treat it as a medication in supplement form, not as a gentle natural alternative.
Practical approach
Diet changes have a significant impact on cholesterol — reducing saturated fat, increasing soluble fibre (oats, psyllium, beans), and eating more omega-3 rich fish can meaningfully improve lipid panels. Supplements add to these dietary foundations.
How to use this guide
The supplements below are ranked by evidence quality for cholesterol-related outcomes. Berberine is the standout for LDL reduction, fish oil for triglycerides. If you are considering red yeast rice, discuss it with your doctor as you would any statin.
Common misconceptions
Supplements replace statins. They do not. Most cholesterol supplements produce 5–10% LDL reductions; statins typically produce 30–50%. Supplements are useful as adjuncts or in mild cases, not substitutes for clinically indicated medication.
Red yeast rice is a safer statin alternative. Red yeast rice contains naturally occurring monacolin K — the same compound as the statin lovastatin. It works through the same mechanism with the same side effects, but with less reliable dose standardisation.
Niacin is still recommended for cardiovascular protection. It was, until large trials (HPS2-THRIVE, AIM-HIGH) showed no benefit and possible harm when added to statins. Niacin is no longer first-line for cardiovascular outcomes, though it can still raise HDL and lower triglycerides.
Plant sterols are universally helpful. They modestly lower LDL but absorb more poorly in people with certain genetic variants, and very high intake may produce small adverse effects in some users. The effect is small and most useful in mild hypercholesterolaemia.
Garlic provides large cholesterol reductions. It produces modest reductions (5–10% LDL), comparable to other supplement-tier interventions, not to medications.
FAQ
How long before I notice effects? For most cholesterol supplements: 8–12 weeks of consistent use, ideally verified with a follow-up lipid panel.
Can I combine supplements with my statin? Many can be safely combined; some (red yeast rice) overlap mechanistically with statins and may compound side effects. Mention all supplements to your prescriber.
Will these lower my triglycerides? Omega-3 fatty acids (particularly at higher doses, 2–4 g/day of EPA+DHA) and berberine have the best evidence for triglyceride reductions among supplements.
What about HDL ("good") cholesterol? HDL is harder to move with supplements. Niacin raises HDL but is no longer recommended for cardiovascular outcomes. Lifestyle interventions (exercise, smoking cessation) move HDL more reliably than supplements.
Are these safe long-term? Most cholesterol-targeting supplements with strong evidence have good long-term safety profiles at standard doses. Red yeast rice at high doses warrants liver enzyme monitoring.
Not sure which supplement is right for you?
Answer a few quick questions and we'll match you to the supplements with the strongest evidence for your situation.
Take the 2-minute quiz →1. Berberine
There is strong evidence that Berberine improves total cholesterol. Grade A, according to Examine.com. Berberine as a supplement is a alkaloid derived from plant root / bark, commonly taken as capsule. Studies typically use 500–1500mg.
Berberine is a compound extracted from several plants, including barberry and goldenseal, and has a long history of use in traditional Chinese and Ayurvedic medicine. It is known to improve blood sugar regulation and insulin sensitivity, with effects comparable to some pharmaceutical treatments for type 2 diabetes. It can also support cholesterol levels and has a positive effect on gut health. It is available as a capsule and is typically taken with meals to reduce digestive discomfort.
2. Astaxanthin
There is strong evidence that Astaxanthin improves high-density lipoprotein (hdl). Grade A, according to Examine.com. Astaxanthin as a supplement is a carotenoid derived from marine algae (haematococcus pluvialis), commonly taken as softgel capsule. Studies typically use 4–12mg.
Strong evidence from multiple human trials shows astaxanthin significantly improves cholesterol profiles, with reductions in the harmful form (LDL) and triglycerides alongside increases in the protective form (HDL). Its mechanism involves protecting LDL particles from oxidation — oxidised LDL is the form most associated with arterial plaque formation — and supporting the liver's clearance of cholesterol from the bloodstream. Effects are typically seen within 4–12 weeks at 6–12mg daily.
3. Niacin (Vitamin B3)
There is strong evidence that Niacin (Vitamin B3) improves triglycerides. Grade A, according to Examine.com. Niacin (Vitamin B3) as a supplement is a synthetically produced vitamin, commonly taken as tablet or capsule. Studies typically use 14–500mg.
Niacin is a B vitamin involved in energy production and the regulation of several metabolic processes. It can support healthy cholesterol levels and has been studied for its effects on cortisol and stress. It is available as a tablet or capsule; a flush-free form is available for those sensitive to the warming skin sensation it can cause.
4. Fish Oil
There is strong evidence that Fish Oil improves triglycerides. Grade A, according to Examine.com. Fish Oil as a supplement is a fatty acid derived from marine (fish), commonly taken as soft gel capsule. Studies typically use 1–3g EPA+DHA.
Fish oil is a source of omega-3 fatty acids, primarily EPA and DHA, which are found in oily fish such as salmon, mackerel, and sardines. It is known to support heart health and reduce triglyceride levels in the blood. It can also support mood, reduce symptoms of depression, and help with joint stiffness. It is available as soft gel capsules or liquid, and higher-EPA formulations are generally more relevant for mood and inflammation.
5. Spirulina
There is strong evidence that Spirulina improves triglycerides. Grade A, according to Examine.com. Spirulina as a supplement is a algae derived from freshwater algae, commonly taken as powder or tablet. Studies typically use 1–8g.
Spirulina produces consistent improvements in cholesterol profiles across multiple human trials, with reductions in total cholesterol, the harmful form (LDL) and triglycerides, alongside modest increases in the protective form (HDL). Its cholesterol-lowering action is attributed to its phycocyanin content and its ability to reduce the oxidation of LDL particles in the bloodstream. The evidence is strongest over 8–12 weeks of daily supplementation.
6. Garlic
There is strong evidence that Garlic improves low-density lipoprotein (ldl). Grade A, according to Examine.com. Garlic as a supplement is a herb derived from plant bulb, commonly taken as capsule or tablet. Studies typically use 600–1200mg (aged garlic extract).
Strong evidence from multiple human trials shows garlic consistently reduces total cholesterol and the harmful form (LDL), with some studies also finding modest improvements in the protective form (HDL). Allicin inhibits an enzyme involved in cholesterol synthesis in the liver — reducing the amount produced and improving clearance from the bloodstream. Effects are most consistent over 8–12 weeks with aged garlic extract at 600–1200mg daily.
7. Phytosterols
There is strong evidence that Phytosterols improves low-density lipoprotein (ldl). Grade A, according to Examine.com. Phytosterols as a supplement is a plant compound derived from plant-derived, commonly taken as capsule or fortified food. Studies typically use 1.5–3g.
Phytosterols are naturally occurring compounds found in plant foods such as nuts, seeds, and vegetable oils. They are structurally similar to cholesterol and are known to reduce LDL cholesterol levels by blocking its absorption in the gut. They are one of the most well-supported dietary supplements for cholesterol management. They are available as capsules and are also added to certain fortified foods such as spreads and yoghurts.
8. Beta-glucans
There is strong evidence that Beta-glucans improves triglycerides. Grade A, according to Examine.com. Beta-glucans as a supplement is a dietary fibre derived from oat / barley / mushroom, commonly taken as capsule or powder. Studies typically use 3–6g (oat); 250–500mg (mushroom).
Beta-glucans are soluble fibres found naturally in oats, barley, and certain mushrooms. They are known to lower LDL cholesterol and support healthy blood sugar levels after meals. They also have well-established immune-supporting properties, particularly the beta-glucans derived from yeast and medicinal mushrooms such as reishi and shiitake. They are available as capsules or powders and can also be obtained in meaningful amounts from a bowl of porridge.
9. Sumac
There is strong evidence that Sumac improves total cholesterol. Grade A, according to Examine.com. Sumac as a supplement is a herbal / spice extract derived from plant, commonly taken as capsule or powder. Studies typically use 500–1000mg.
Sumac is a tart spice derived from the dried berries of the Rhus coriaria plant, commonly used in Middle Eastern cooking. As a supplement it can support blood sugar management and muscle recovery. It is available as a capsule or powder.
10. Apple Cider Vinegar
There is good evidence that Apple Cider Vinegar improves triglycerides. Grade B, according to Examine.com. Apple Cider Vinegar as a supplement is a fermented food extract derived from plant, commonly taken as liquid or capsule or gummy. Studies typically use 15–30ml or equivalent.
Apple cider vinegar is made from fermented apple juice and has been used for centuries as a food and folk remedy. It can support blood sugar management after meals, and may help with appetite and weight management when taken regularly. It is available as a liquid, capsule, or gummy.
