Citrus Bioflavonoid Concentrate Blend
Also known as: Citrus bioflavonoids, Citrus flavonoids, Hesperidin, Naringenin, Eriocitrin, Citrus Bioflavonoids
Overview
Citrus bioflavonoids are a group of polyphenolic compounds found abundantly in citrus fruits such as oranges, lemons, and grapefruits. These compounds, including hesperidin, naringenin, and eriocitrin, are recognized for their antioxidant properties and potential health benefits. As a dietary supplement, citrus bioflavonoids are primarily used to support cardiovascular health and manage diabetes. They are known for their ability to scavenge free radicals and provide cardioprotective effects. Research on citrus bioflavonoids is ongoing, with increasing evidence from clinical trials suggesting various health benefits. The quality of evidence varies, but systematic reviews and meta-analyses provide strong support for certain applications. These supplements are available in various forms, including capsules and tablets, making them accessible for daily use.
Benefits
Citrus bioflavonoids have demonstrated several evidence-based benefits. A meta-analysis showed a significant improvement in endothelial function, with a 2.75% increase in flow-mediated vasodilation (FMD), indicating enhanced cardiovascular health. Additionally, citrus bioflavonoid supplementation has been shown to reduce senile purpura lesions by 50% in a clinical study. These compounds may also reduce oxidative stress in patients with type 2 diabetes, offering potential benefits for metabolic health. The effect sizes observed in studies, particularly for FMD improvement, suggest clinically relevant improvements. Benefits can be observed within weeks, as demonstrated in studies on senile purpura.
How it works
Citrus bioflavonoids exert their effects through several biological pathways. Primarily, they act as antioxidants, scavenging free radicals and reducing oxidative stress. They may also inhibit dipeptidyl peptidase-4 (DPP-4), which can improve glucose metabolism. Furthermore, citrus bioflavonoids enhance vascular function, contributing to cardiovascular health. These compounds interact with the cardiovascular system, metabolic pathways, and skin health. Their molecular targets include free radicals and the DPP-4 enzyme. While generally well-absorbed, specific bioavailability data for citrus bioflavonoids remains limited.
Side effects
Citrus bioflavonoids are generally considered safe, with minimal adverse effects reported in clinical trials. Common side effects are not frequently reported. Some individuals may experience potential gastrointestinal upset, although this is not commonly documented. Significant rare side effects have not been reported. Potential interactions with medications affecting blood sugar or blood pressure are possible, although specific data is limited. Caution is advised in diabetes management due to potential effects on blood sugar levels. Pregnant or breastfeeding women should consult healthcare providers before use. Overall, citrus bioflavonoids have a favorable safety profile when used as directed.
Dosage
The minimum effective dose of citrus bioflavonoids is not well-established, but doses as low as 19 mg per day have been used in studies. Optimal dosage ranges typically fall between 200 mg to 560 mg per day, based on available supplements. The maximum safe dose is not clearly defined, but high doses are generally well-tolerated. There are no specific timing recommendations available for taking citrus bioflavonoids. They are available in various supplement forms, including capsules and tablets. Bioavailability may be influenced by food intake, although specific data is limited. No specific cofactors are required for their absorption or activity.
FAQs
Are citrus bioflavonoids safe?
