Mixed Citrus Bioflavonoids
Also known as: Citrus bioflavonoids, Citrus flavonoids, Hesperidin, Naringenin, Eriocitrin, Mixed Citrus Bioflavonoids
Overview
Mixed Citrus Bioflavonoids are polyphenolic compounds predominantly found in citrus fruits like oranges, lemons, and grapefruits. These flavonoids, including hesperidin, naringenin, and eriocitrin, are noted for their antioxidant properties and potential health benefits. They are commonly used for cardioprotection, improving dyslipidemia, and enhancing overall antioxidant defenses in the body. While the body of research on these compounds is growing, the quality and consistency of the studies vary, necessitating further exploration to solidify their health claims. The supplementation forms typically include powders, capsules, and tablets, reflecting a broad interest in their potential therapeutic applications.
Benefits
Mixed Citrus Bioflavonoids have demonstrated several evidence-based benefits. Key findings include their cardioprotective effects, particularly an increase in flow-mediated vasodilation (FMD) by 2.75% in meta-analyses, indicating improved endothelial function. Additionally, they show promise in managing dyslipidemia, with studies suggesting reductions in total cholesterol, LDL, and triglycerides, alongside increased HDL, although the evidence is variable across studies. There are also indications of potential benefits in reducing adiposity and regulating enzymes related to obesity. Individuals with cardiovascular risk factors may derive significant advantages from these compounds, but the overall effect sizes necessitate further investigation for more uniform conclusions.
How it works
The primary mechanisms of action for Mixed Citrus Bioflavonoids involve their antioxidant activity, which helps combat oxidative stress and inflammation, as well as their role in modulating lipid metabolism. They may enhance endothelial function and improve vascular health through dipeptidyl peptidase-4 (DPP-4) inhibition, which is linked to cardiovascular benefits. The interaction with body systems, particularly the cardiovascular system and lipid metabolism pathways, underlines their potential therapeutic properties. Absorption rates can vary based on the specific bioflavonoid and the form of supplementation.
Side effects
Mixed Citrus Bioflavonoids are generally regarded as safe when consumed in typical dietary amounts. Common side effects, though not well-documented, may include mild gastrointestinal upset. Uncommon side effects such as allergic reactions or interactions with certain medications have been reported for approximately 1-5% of users. The risk of adverse effects is minimal, but individuals taking blood thinners or medications metabolized by CYP enzymes should be cautious. As there are no established contraindications, particular care should be exercised by those with citrus allergies. Pregnant or breastfeeding women are advised to consult healthcare providers prior to usage to ensure safety and efficacy.
Dosage
The dosages in studies evaluating the health benefits of Mixed Citrus Bioflavonoids generally range from 19 mg to 560 mg per day, with optimal ranges typically cited between 100 mg to 500 mg daily for cardiovascular benefits. While no maximum safe dose is firmly established, high doses could correlate with increased side effects. There are no specific timing recommendations for consumption, although bioavailability may be enhanced when taken with food. The common available forms are capsules or tablets, which can also impact absorption rates.
