Statins lowered blood CoQ10 in 12 trials, so many red yeast rice products now add CoQ10 to the capsule. Whether that helps is less clear: 2 meta-analyses of muscle symptoms reached opposite answers.
This page separates what is known about each step of that argument.
Quick Answer: Should You Take CoQ10 With Red Yeast Rice?
Probably not essential, and unproven for red yeast rice. Statins lower blood CoQ10, and red yeast rice depleted CoQ10 in mice, but we found no human study of that. For statin muscle pain, a 2018 meta-analysis of 12 trials found benefit and a 2020 analysis of 7 found none. CoQ10 lowers LDL only about 3 mg/dL.
Key Takeaways
- 12 trials with 1,776 people found statins lower circulating CoQ10.
- Red yeast rice cut liver and heart CoQ10 in 1 mouse study.
- A 2018 meta-analysis of 12 trials found CoQ10 eased statin muscle pain.
- A 2020 analysis of 7 trials found no benefit for myalgia.
- Across 50 trials, CoQ10 lowered LDL by only 3.03 mg/dL.

Why CoQ10 Comes Up
Statins block the enzyme that starts cholesterol production, and the same pathway also makes CoQ10. Monacolin K blocks that enzyme too.
- Shared pathway: Cholesterol and CoQ10 both come from it.
- Statins: Lower blood CoQ10 in placebo-controlled trials.
- Red yeast rice: Depleted liver and heart CoQ10 in mice.
- People on red yeast rice: No direct measurement found.
An 8-arm analysis in 2015 found statins cut plasma CoQ10 by 0.44 micromol/L.[1]Statin therapy and plasma coenzyme Q10 concentrations: a systematic review and meta-analysis — Pharmacological Research (2015) View source A 2018 update of 12 trials agreed.[2]The effect of statin treatment on circulating coenzyme Q10 concentrations: an updated meta-analysis — European Journal of Medical Research (2018) View source
How monacolin K acts in the first place is covered in how red yeast rice works.
The Evidence, Step by Step
The case for adding CoQ10 has 4 steps, and each rests on a different kind of evidence.
| Question | Evidence | Answer |
|---|---|---|
| Do statins lower blood CoQ10? | 12 trials, 1,776 people, 2018 | Yes |
| Does red yeast rice lower CoQ10? | 1 mouse study, 2005 | In mice, at high doses |
| Does CoQ10 ease statin muscle pain? | 12 trials, 575 people, 2018 | Yes, pain scores fell |
| The same question again | 7 trials, 321 people, 2020 | No benefit |
| Does CoQ10 lower LDL itself? | 50 trials, 2,794 people, 2022 | Down 3.03 mg/dL |
The mouse study gave up to 5 g per kg, about 5 times a typical human dose, and saw liver CoQ10 fall within 30 minutes.[3]Acute administration of red yeast rice depletes tissue coenzyme Q10 levels in ICR mice — British Journal of Nutrition (2005) View source
Every human step concerns prescription statins. Why statin findings apply here at all is explained in the lovastatin connection.
Two Meta-Analyses, Opposite Answers
On the question people actually care about, muscle aches, the evidence splits.
- 2018, 12 trials, 575 patients: Pain, weakness, cramps and tiredness improved.
- 2018: Creatine kinase, a muscle damage marker, did not change.
- 2020, 7 trials, 321 patients: No improvement in muscle pain.
- 2020: No effect on staying on statins.
The 2018 analysis concluded CoQ10 may help.[4]Effects of Coenzyme Q10 on Statin-Induced Myopathy: An Updated Meta-Analysis — Journal of the American Heart Association (2018) View source The 2020 review found only 2 of its studies positive.[5]Effect of Coenzyme Q10 on statin-associated myalgia and adherence to statin therapy — Atherosclerosis (2020) View source
What Combination Products Have Shown
Several trials tested red yeast rice and CoQ10 together. They show the pair lowers LDL, not what CoQ10 adds.
- 2016, 40 adults: 10 mg monacolins and 30 mg CoQ10 for 6 months; LDL down 26.3%.
- 2018, 104 adults: 2 months, with metabolic syndrome; LDL down 21.8%.
- 2023, 105 adults: 3 mg monacolin K with CoQ10 and plant extracts; LDL down 16.8%.
- Muscle question: No trial among 44 PubMed titles compared the pair with rice alone.
The 2016 trial ran against placebo.[6]Red Yeast Rice Plus Coenzyme Q10 Improves Lipid Pattern, Endothelial Reactivity and Arterial Stiffness — Annals of Nutrition and Metabolism (2016) View source The 2018 trial compared against diet alone and reported the product as safe and well tolerated.[7]Effect of Monacolin K and CoQ10 supplementation in hypertensive and hypercholesterolemic subjects — Biomedicine and Pharmacotherapy (2018) View source
The 2023 trial compared 3 mg and 10 mg monacolin K arms.[8]Low Dose Monacolin K Combined with Coenzyme Q10, Grape Seed, and Olive Leaf Extracts Lowers LDL Cholesterol — Nutrients (2023) View source Those drops sit in the range of red yeast rice trials without CoQ10, listed in the LDL trial results.
Should You Add CoQ10?
It is a reasonable question for your clinician, not a required step.
- Why people add it: Past muscle aches on a statin.
- What it did not change: Creatine kinase, in the 2018 analysis.
- Dose in the 2016 trial: 30 mg a day.
- Its own LDL effect: 3.03 mg/dL across 50 trials.
That LDL figure comes from a 2022 meta-analysis.[9]Effects of Coenzyme Q10 Supplementation on Lipid Profiles in Adults: A Meta-analysis — Journal of Clinical Endocrinology and Metabolism (2022) View source Our red yeast rice blend contains no CoQ10, so the 2 doses stay separate and visible.
CoQ10 Is Not a Safety Net
The biggest risk in the CoQ10 story is false reassurance.
- Muscle pain on red yeast rice: Stop and get checked, CoQ10 or not.
- Dark urine or weakness: Seek urgent assessment.
- A prescribed statin: Still never combine.
- Your pharmacist: Should know about both products.
Those warning signs match the ones listed for lovastatin.[10]Lovastatin Drug Information — MedlinePlus, National Library of Medicine View source If you take red yeast rice with liver safeguard capsules and add CoQ10, keep both on your medicine list with their doses written down.
Stop and Speak to a Clinician If
- You take a prescribed statin or any other cholesterol medicine
- You are pregnant, trying to conceive or breastfeeding
- You have liver or kidney disease, or drink alcohol heavily
- You take cyclosporine, or medicines your pharmacist flags for lovastatin
- You have had muscle pain, weakness or dark urine on a statin before
Frequently Asked Questions
Do I need to take CoQ10 with red yeast rice? +
No study shows you must. Statins lowered blood CoQ10 in 12 trials, but whether adding it prevents muscle aches is split between 2 meta-analyses.
Which is better, CoQ10 or red yeast rice? +
They do different jobs. For LDL, red yeast rice lowered it about 34 to 39 mg/dL in pooled trials, while CoQ10 lowered it 3.03 mg/dL across 50 trials.
Can CoQ10 help lower cholesterol? +
Only slightly. A 2022 meta-analysis of 50 trials found LDL fell 3.03 mg/dL and total cholesterol 5.53 mg/dL.
What are the potential side effects of taking red yeast rice with CoQ10? +
Mainly those of red yeast rice: statin-type muscle and liver effects. A 2018 combination trial of 104 adults reported it as safe and well tolerated.
What's the best time of day to take red yeast rice with CoQ10? +
No trial tested timing for the pair. Statin evidence favours the evening for short-acting forms, so 1 evening meal for both is a simple routine.
Does red yeast rice lower CoQ10 levels? +
In mice, yes: a single high dose cut liver and heart CoQ10 within 30 minutes. We found no human study measuring it.
How much CoQ10 is in combination products? +
The 2016 trial used 30 mg of CoQ10 with 10 mg of monacolins. Amounts vary by product, so check the label.
Does CoQ10 stop statin muscle pain? +
The evidence conflicts: 12 trials pooled in 2018 found less pain, while 7 trials pooled in 2020 found no benefit.
Should I take CoQ10 if I get muscle pain on red yeast rice? +
Stop the red yeast rice and see a clinician first. Muscle pain with dark urine can signal rhabdomyolysis, and US reports include 27 such cases with red yeast rice.
