Why Monacolin K Works
Monacolin K is the active compound in Red Yeast Rice. It contributes to the maintenance of normal blood cholesterol levels.*
Supports Normal Cholesterol Production*
Monacolin K works by inhibiting HMG-CoA reductase — the enzyme your liver uses to produce cholesterol. This is the same mechanism of action behind lovastatin, one of the most widely prescribed statins in the world.
Clinically Studied Dose
Monacolin K contributes to the maintenance of normal blood cholesterol levels.* Every capsule contains the clinically studied dose backed by published research in peer-reviewed journals.
Superior Bioavailability*
Research suggests that Monacolin K in its natural red yeast rice form has higher bioavailability than the equivalent synthetic compound, delivering more potent cholesterol-lowering effects milligram-for-milligram.*
15+ Clinical Trials on Monacolin K
Monacolin K has been studied extensively in randomised controlled trials across the world. Here are some of the key findings.
LDL-C decreased by 26.3% and total cholesterol by 20.4% versus placebo*
79 hypercholesterolemic patients received red yeast rice (1.2 g/day) or placebo for 8 weeks in a double-blind RCT. The treatment group also saw significant reductions in ApoB and the LDL/HDL ratio.*
View StudyLDL cholesterol reduced by 43 mg/dL in statin-intolerant patients*
62 patients with dyslipidemia who had previously discontinued statins due to myalgias were randomised to red yeast rice or placebo for 24 weeks. The treatment group saw significant LDL and total cholesterol reductions without increased muscle pain.*
View Study10 mg monacolin K reduced LDL-C by 26.5% in 8 weeks*
105 subjects with mild hypercholesterolemia were randomised to lifestyle modification alone, lifestyle + 3 mg monacolin K, or lifestyle + 10 mg monacolin K. Even the low-dose 3 mg group saw a significant 16.8% LDL reduction.*
View Study23% LDL and 15.5% total cholesterol reduction in 16-week RCT*
42 patients received red yeast rice (9.6 mg total monacolins) or placebo. 70% of the treatment group reached an LDL level below 3.0 mmol/L, compared to only 5% in the placebo group.*
View StudyLDL lowered by 22% and total cholesterol by 15% in physicians' study*
52 physicians and spouses with total cholesterol above 200 mg/dL took 10.5 mg monacolin K daily for 8 weeks. The placebo group saw no reduction whatsoever.*
View Study37.2% LDL reduction at 24 weeks with 5 mg monacolin K + diet*
80 men and women were randomised to a low-energy diet alone or diet plus 5 mg monacolin K for 24 weeks. The treatment group also saw a 38.3% increase in HDL ("good") cholesterol.*
View Study22% LDL reduction in just 4 weeks with 10 mg monacolins*
25 mildly hypercholesterolemic subjects took 10 mg monacolins daily for 4 weeks versus placebo. Total cholesterol dropped 12.5% and non-HDL cholesterol dropped 14.7%.*
View Study187 participants over 52 weeks — sustained LDL reduction*
In the longest study, 187 participants took red yeast rice for a full year. Mean LDL dropped from 150 to 113 mg/dL and was maintained throughout. HDL increased significantly by week 52.*
View StudySystematic review: all 12 RCTs showed significant cholesterol reduction*
A 2024 systematic review analysed 12 randomised controlled trials with 769 participants. Every single study found a statistically significant reduction in LDL and total cholesterol (p < 0.05), regardless of the monacolin K dose (2–10 mg/day).*

We 3rd Party Test Every Batch for Monacolin K
Monacolin K is the key compound in Red Yeast Rice responsible for its cholesterol-reducing effects.* But here's the problem — the amount of Monacolin K in supplements can vary by a factor of 100× between brands.
That's why we send every single batch to an independent ISO 17025-accredited laboratory (SORA Labs) to verify the exact Monacolin K content. If it doesn't meet our specification, we don't sell it.
We then publish every test result publicly, so you can check exactly what's in your capsule before you buy.

More Than Just Cholesterol
Stops Feeding Plaque*
LDL cholesterol is the raw material that builds up inside artery walls. By reducing LDL production, you stop supplying plaque with the resources it needs to grow.*
Lowers Total Cholesterol*
Clinical trials show average reductions of 11–20% in total cholesterol within 8–12 weeks of daily use.*
Well Tolerated
Low-dose Monacolin K has minimal associated side effects, making it suitable for long-term daily use.*
Cardiovascular Support*
Long-term research links Red Yeast Rice with significant reductions in cardiovascular events.*

Break It Down. Stop It Coming Back.
Arterial plaque is built from LDL cholesterol, calcium, and fibrin — a sticky protein that binds it all together. Over time, this narrows your arteries and restricts blood flow, increasing your risk of cardiovascular events.*
Nattokinase goes after existing plaque. It's a fibrinolytic enzyme that supports your body's natural ability to break down fibrin — the glue holding plaque together inside your arteries.*
Cholesterol Support stops it coming back. By reducing LDL cholesterol production in the liver via Monacolin K, you cut off the supply of raw material that plaque needs to rebuild.*
Together, they work from both ends: Nattokinase helps clear what's already there, while Cholesterol Support prevents the conditions for it to return.*
