Trans Resveratrol Complex Proprietary Blend
Also known as: Resveratrol, trans-resveratrol, 3,5,4'-trihydroxy-trans-stilbene, Trans-resveratrol
Overview
Trans-resveratrol is a naturally occurring polyphenolic compound found in various plants, particularly in red grapes and berries. Characterized by its antioxidant and anti-inflammatory properties, it is classified within the broader categories of antioxidants, anti-aging, and heart health supplements. Research shows that resveratrol may improve cardiovascular health, support metabolic regulation, and exhibit potential neuroprotective effects. However, its bioavailability is a challenge due to its low water solubility and rapid metabolism. Its research maturity is moderate, with evidence derived from both high-quality systematic reviews and meta-analyses, although results can be inconsistent. It is generally well-tolerated but requires attention to dosage and co-factors that may influence absorption.
Benefits
Key benefits of trans-resveratrol include improved cardiovascular health through significant reductions in inflammatory markers such as CRP and TNF-α (MD = -0.63 for CRP, p = 0.01; MD = -0.55 for TNF-α, p = 0.02). Furthermore, it has shown promise in enhancing glucose and lipid metabolism, especially in populations suffering from obesity and diabetes (SMD = -0.36 for waist circumference, SMD = -0.48 for HbA1c, p ≤ 0.001). Although secondary effects suggest possible anti-cancer and neuroprotective properties, the evidence for these is less robust. Overall, metabolic parameters can improve within weeks to months of supplementation, although outcomes will vary among individuals.
How it works
Trans-resveratrol exerts its effects primarily through anti-inflammatory and antioxidant mechanisms. It modulates various signaling pathways, including those involved in inflammation and metabolism, thereby enhancing insulin sensitivity and lipid regulation. Moreover, its metabolic effects engage numerous biological pathways, which interact with the cardiovascular and nervous systems. Despite its therapeutic promise, trans-resveratrol's efficacy is limited by low bioavailability, primarily due to rapid metabolic conversion into less active forms such as glucuronides.
Side effects
Trans-resveratrol is generally well-tolerated, with few adverse effects reported. Commonly, no side effects are consistently documented across studies. However, mild gastrointestinal disturbances may be encountered in sensitive individuals or at high doses (1-5%). Notably, rare side effects are not well-documented. Interactions with blood thinners and diabetes medications may occur, necessitating caution in patients taking these drugs. Pregnant and breastfeeding individuals are advised to avoid resveratrol, given the insufficient data on its safety in these populations. Additionally, caution is advised for patients with bleeding disorders or those on anticoagulants due to potential increased bleeding risk.
Dosage
The typical minimum effective dose of trans-resveratrol has not been firmly established, but initial recommendations generally start at 100-200 mg per day. To achieve potential health benefits, an optimal range of 250-500 mg per day is suggested, while some studies allow for maximum doses of up to 5 g per day, though higher doses may lead to gastrointestinal side effects. Specific timing for administration is not universally established, but taking resveratrol with meals, particularly those containing fats, may enhance absorption. Currently, no required co-factors have been established, though factors such as food composition could play a role in its bioavailability.
