Organic Whole Grape Resveratrol Extract
Also known as: Resveratrol, Organic Grape Resveratrol Extract, Organic Whole Grape Resveratrol Extract
Overview
Organic Whole Grape Resveratrol Extract is a dietary supplement derived from red grapes, known for their high concentration of resveratrol and other beneficial polyphenols. Resveratrol, a polyphenol compound, is particularly abundant in the skin of red grapes. This extract is primarily utilized for its antioxidant properties, with potential applications in supporting cardiovascular health, promoting anti-aging effects, and aiding in disease prevention. It contains a combination of resveratrol, anthocyanins, and other polyphenols, contributing to its potential health benefits. While research into its efficacy is ongoing, current evidence suggests moderate potential, with some studies indicating positive outcomes, while others call for further investigation to establish conclusive results. It is available in various forms, with whole grape extracts potentially offering enhanced absorption due to synergistic effects.
Benefits
Resveratrol may improve cardiovascular health by reducing oxidative stress markers and improving lipid profiles, as suggested by some studies. However, the specific quantified outcomes can vary. Secondary benefits include potential anti-aging effects, neuroprotection, and cancer prevention, although more robust evidence is needed to confirm these. Individuals at risk of cardiovascular diseases or those seeking antioxidant supplementation may find it particularly beneficial. The effect sizes vary widely, and more research is necessary to establish consistent clinical significance. Benefits may be observed over several weeks to months of consistent supplementation.
How it works
Resveratrol primarily functions as an antioxidant, influencing biological pathways related to inflammation, cell survival, and metabolism. It interacts with the cardiovascular, nervous, and metabolic systems. At the molecular level, resveratrol targets pathways such as SIRT1, AMPK, and NF-κB. While resveratrol's bioavailability is generally low due to rapid metabolism, whole grape extracts may enhance absorption through synergistic effects. This synergistic action potentially improves the overall effectiveness of the supplement by allowing for better utilization of its components within the body.
Side effects
Resveratrol is generally considered safe at moderate doses. Common side effects, occurring in more than 5% of users, include gastrointestinal discomfort. Uncommon side effects, affecting 1-5% of users, may include headaches and dizziness. Rare side effects, seen in less than 1% of users, include allergic reactions. It may interact with blood thinners and diabetes medications, potentially altering their effects. It is contraindicated in pregnancy and breastfeeding due to insufficient safety data. Caution is advised in individuals with bleeding disorders or those taking anticoagulant medications. Always consult with a healthcare provider before starting resveratrol supplementation, especially if you have pre-existing health conditions or are taking other medications.
Dosage
The minimum effective dose of resveratrol typically starts at 100 mg per day. Optimal dosage ranges are between 100-500 mg per day, depending on the specific formulation and desired effects. It is generally considered safe up to 1,000 mg per day, although higher doses may increase the risk of side effects. For best absorption, it should be taken with meals, particularly those containing fats. Whole grape extracts may offer better bioavailability compared to isolated resveratrol. No specific cofactors are required for its absorption or activity.
