Coenzyme Q10 and Vitamin B2: what the published research says

PubMed indexes 8 records that name Coenzyme Q10 and Vitamin B2 together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Coenzyme Q10 and Vitamin B2. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

8 studies naming Coenzyme Q10 and Vitamin B2.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Open Label Prospective Experience of Supplementation with a Fixed Combination of Magnesium, Vitamin B2, Feverfew, Andrographis Paniculata and Coenzyme Q10 for Episodic Migraine Prophylaxis.

Journal of clinical medicine · 2020 · PMID 33375459

“The supplementation we have tested appears to be an effective and well-tolerated preventive approach against EM. A randomized, placebo-controlled study is needed to confirm our results.”

Vikelis et al. · Authors' conclusion

Names both Coenzyme Q10 and Vitamin B2 in its title.

Increased muscle coenzyme Q10 in riboflavin responsive MADD with ETFDH gene mutations due to secondary mitochondrial proliferation.

Molecular genetics and metabolism · 2013 · PMID 23628458

Human subjects

“The expression of CoQ10 biosynthesis genes showed no significant changes whereas genes involved in lipid metabolism, such as PPARα, were marked up regulated. Our results suggested that CoQ10 seems not to be a primary factor in riboflavin responsive MADD and the apparent increase in CoQ10 may be secondary to mitochondrial proliferation.”

Wen et al. · From the abstract

Names both Coenzyme Q10 and Vitamin B2 in its title.

Secondary coenzyme Q10 deficiency and oxidative stress in cultured fibroblasts from patients with riboflavin responsive multiple Acyl-CoA dehydrogenation deficiency.

Human molecular genetics · 2013 · PMID 23727839

Human subjects

“Additionally, riboflavin-depleted control fibroblasts showed moderate CoQ10 deficiency, but not increased mitochondrial ROS, indicating that variant ETF-QO proteins and not CoQ10 deficiency are the causes of mitochondrial ROS production in the patient cells. Accordingly, the corresponding variant Rhodobacter sphaeroides ETF-QO proteins, when overexpressed in vitro, bind a CoQ10 pseudosubstrate, Q10Br, less tightly than the wild-type ETF-QO protein, suggesting that molecular…”

Cornelius et al. · From the abstract

Names both Coenzyme Q10 and Vitamin B2 in its title.

CoEnzyme Q10 and riboflavin: the mitochondrial connection.

Headache · 2012 · PMID 23030537

ReviewHuman subjects

“Arising from these extensive neurophysiological studies, the treatment of metabolic encephalomyopathies with pharmacological doses of riboflavin and coenzyme Q10 has shown positive benefits. The same treatment has now been applied to migraine, adding clinical support to the theory that migraine is a mitochondrial disorder.”

Markley · Authors' conclusion

Names both Coenzyme Q10 and Vitamin B2 in its title.

Ameliorating effect of coenzyme Q10, riboflavin and niacin in tamoxifen-treated postmenopausal breast cancer patients with special reference to lipids and lipoproteins.

Clinical biochemistry · 2007 · PMID 17425952

Human subjects

“The study figures the altered lipid and lipoprotein levels in the untreated and TAM-treated breast cancer patients. On combination therapy with Co Q10, riboflavin and niacin, it counteracts the tamoxifen-induced hyperlipidemia to normal levels.”

Yuvaraj et al. · Authors' conclusion

Names both Coenzyme Q10 and Vitamin B2 in its title.

Role of magnesium, coenzyme Q10, riboflavin, and vitamin B12 in migraine prophylaxis.

Vitamins and hormones · 2004 · PMID 15196887

ReviewHuman subjects

“This chapter reviews the involvement of some mineral, coenzyme, and vitamin defects in the pathogenesis of migraine headaches and focuses on their potential therapeutic use in the preventive treatment for migraine. The therapeutic potential of magnesium, coenzyme Q(10), riboflavin, and vitamin B(12) can be cautiously inferred from some published open clinical trials; it should, however, be considered that double-blind randomized larger studies are needed to correctly…”

Bianchi et al. · From the abstract

Names both Coenzyme Q10 and Vitamin B2 in its title.

Preventive Therapy of Migraine.

Continuum (Minneapolis, Minn.) · 2018 · PMID 30074549

Case ReportsResearch Support, N.I.H., ExtramuralResearch Support, U.S. Gov't, Non-P.H.S.Human subjects

Names Coenzyme Q10 and Vitamin B2 together in an interaction, co-administration, or pharmacokinetic context.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Coenzyme Q10, Vitamin B2, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
