Neolife Proprietary Polyphenol Blend
Also known as: Flavonoids, Phenolic Acids, Stilbenes, Antioxidants, Phytochemicals, Polyphenols
Overview
Polyphenols are a diverse class of naturally occurring compounds predominantly found in plant foods such as fruits, vegetables, nuts, and seeds. They are recognized for their potent antioxidant properties, helping to neutralize free radicals and reduce oxidative stress. Beyond their antioxidant activity, polyphenols exhibit anti-inflammatory properties and have been studied for various health benefits including support for cardiovascular health, enhancement of cognitive function, and potential improvements in physical performance. The body of research surrounding polyphenols is moderate to high, with systematic reviews and meta-analyses highlighting their effects. However, the quality of evidence can vary, leading to mixed results in studies. Sources of polyphenols are abundant in a typical diet that emphasizes plant-based foods.
Benefits
Polyphenols are associated with several significant health benefits. Key evidence suggests that polyphenol supplementation can improve cardiovascular health, notably through improvements in blood pressure, lipid profiles, and glycemic control, as indicated by several meta-analyses. Specific polyphenols such as flavonoids have also been linked to enhancements in cognitive function, particularly in memory retrieval. Additionally, there is emerging evidence supporting moderate enhancements in physical performance and potential benefits for individuals with diabetic nephropathy, showing reductions in HbA1c and proteinuria. The effect sizes for benefits vary, with studies demonstrating improvements ranging from 0.74% to 3.0% in performance metrics related to specific polyphenols.
How it works
Polyphenols function primarily as antioxidants, mitigating oxidative stress and thereby reducing inflammation. They influence various biological pathways involved in cardiovascular health and cognitive function by modulating enzymatic activities and receptor signaling. Polyphenols can actively interact with the cardiovascular, nervous, and metabolic systems, and their bioavailability is influenced by factors such as dietary fat intake, which enhances their absorption.
Side effects
Polyphenols are generally recognized as safe when consumed in moderate amounts, and serious adverse effects are uncommon. Gastrointestinal upset is the most commonly reported side effect, but typically occurs in a minority of users. Rare occurrences of allergic reactions or drug interactions have been documented, particularly concerning blood thinners and diabetes medications. Although specific contraindications have not been firmly established, caution is advised for pregnant or breastfeeding women due to the limited research on safety in these populations. Individuals with certain medical conditions should consult healthcare providers before starting polyphenol supplements to avoid potential interactions.
Dosage
The effective dosage of polyphenols can vary significantly among the different types. For instance, quercetin is often recommended at dosages ranging from 500 to 1000 mg/day, whereas a typical range for many polyphenols is between 500 and 2000 mg/day. While no established maximum safe dose exists, high intakes may pose increased risk of side effects. Timing is important for absorption; polyphenols are best taken with meals, which can enhance their bioavailability. Additionally, lipid-based formulations can further improve absorption, making it essential to consider food interactions.
