Health Benefits & Sources
Why You Need It
- Metabolic Balance: Helps regulate how your body processes sugars and fats.
- Vascular Strength: Supports the integrity of your blood vessels, reducing fragility.
- Antioxidant Shield: Neutralizes free radicals that cause cellular aging.
Deep Dive
Flavoglycosides act as a double-edged sword for health. First, they provide vasoprotective benefits. Research suggests they strengthen capillary walls, making them less prone to leakage and bruising. This is crucial for maintaining healthy circulation.
Secondly, they play a role in metabolic regulation. Unlike simple sugars which spike blood glucose, the glycoside structure modulates absorption. When you consume foods rich in these compounds, you are essentially giving your body the raw materials to lower oxidative stress and improve blood flow. This is why they are often concentrated in supplements for 'venous health' (like varicose veins).
Natural Food Sources
Nature provides the safest and most bioavailable forms of flavoglycosides. They are often found in the skins, seeds, and peels of fruits, or in specific bitter herbs.
| Food | Amount | % DV (Est.) |
|---|---|---|
| Bilberries | 100g | ~150% |
| Grape Seeds | 10g | ~80% |
| Green Tea | 1 cup | ~40% |
| Citrus Peel | 1 tbsp | ~20% |
| Buckwheat | 1 cup | ~35% |
Supplementation
While eating whole foods is best, concentrated extracts (often labeled as 'Standardized Flavoglycosides') are available. These are typically derived from Ginkgo Biloba, Grape Seed Extract, or Bilberry.
Dosage: There is no official RDA. However, clinical studies often use extracts yielding 120mg to 240mg of flavoglycosides daily. Always follow the manufacturer's instructions.

Safety & Side Effects
Safety & Side Effects
Flavoglycosides are generally considered safe when consumed through food.
Supplement Caution:
- Blood Thinners: Because they affect blood vessel tone and circulation, they may interact with anticoagulants (like Warfarin). Consult a doctor.
- Surgery: Discontinue use at least 2 weeks before scheduled surgery due to potential bleeding risks.
- Digestive Upset: High doses of concentrated extracts can cause mild nausea or stomach cramping in sensitive individuals.
Who should avoid: Pregnant or breastfeeding women should stick to dietary sources and avoid high-dose supplements unless advised by a healthcare provider.
