Robuvit French Oak Extract
Also known as: Robuvit®, French oak wood extract, Extract from Quercus robur, Robuvit
Overview
Robuvit® is a standardized dietary supplement derived from the wood of *Quercus robur*, commonly known as French oak. It is rich in polyphenols, particularly ellagitannins such as roburins, gallic acid, ellagic acid, vescalagin, and castalagin. The extract is known for its antioxidant properties and is typically standardized to contain over 40% polyphenols. Robuvit® is recognized for its potential to support energy levels, reduce fatigue, enhance liver function, and improve overall health and well-being. With over 20 clinical trials involving more than 1,100 subjects, Robuvit® shows a moderate level of research maturity, although systematic reviews or meta-analyses are lacking. The most important effects backed by research include improvements in energy and fatigue, liver function in patients with hepatic conditions, and support for post-surgical recovery.
Benefits
Robuvit® has several evidence-based benefits, including: 1. **Energy and Fatigue**: Significant improvements in energy levels and reduction of fatigue have been observed, particularly in male participants who reported enhanced mental and mood attributes over four weeks of supplementation. 2. **Liver Health**: In patients with moderate hepatic failure, Robuvit® led to noteworthy enhancements in liver function, including improvements in albumin, ALT, AST, and bilirubin levels. 3. **Post-Surgical Recovery**: It has shown efficacy in enhancing recovery and quality of life in patients following surgery, particularly after hysterectomy. 4. **Antioxidant Activity**: The antioxidant properties improve levels of key antioxidant enzymes and reduce oxidative stress. 5. **Mitophagy and Energy Capacity**: The metabolites, especially urolithins, are linked with increased cellular energy capacity. Conditions benefiting from Robuvit® include chronic fatigue syndrome and symptoms associated with aging in elderly men.
How it works
The beneficial effects of Robuvit® are primarily due to its polyphenolic constituents, particularly ellagitannins. These compounds are metabolized by gut microbiota into urolithins A, B, and C. These metabolites enhance mitochondrial function and promote mitophagy, which helps to clear damaged mitochondria, thus improving cellular energy capacity. They also exert significant antioxidant and anti-inflammatory effects, contributing to the overall health benefits associated with Robuvit®.
Side effects
Robuvit® has shown a very good safety profile, with clinical studies indicating no significant adverse effects reported. Common side effects (>5%) are absent, and there is no data on uncommon side effects (1-5%) or rare side effects (<1%). No drug interactions have been documented. Furthermore, no specific contraindications have been identified, making it safe for varied populations, including those recovering from surgery or with liver issues. Special population considerations indicate that Robuvit® is well-tolerated in various clinical scenarios, reinforcing its safety profile.
Dosage
The recommended minimum effective dose of Robuvit® is typically 300 mg per day, which aligns with dosages used in several clinical studies. This dosage is effective for improving energy, mood, and liver function. There is no defined maximum safe dose, as doses of 300 mg daily have been used without reported adverse effects. Timing of intake is flexible; it can be seamlessly included in a daily supplement regimen. Robuvit® is usually provided in a standardized form to ensure at least 40% polyphenol content, with efficient absorption facilitated by gut bacteria metabolism.
