Ask Anything.
How does quercetin work?
Quercetin is a polyphenol antioxidant that helps neutralise free radicals and supports a balanced inflammatory response. In Quercefit® form, it’s more bioavailable, supporting immune health, recovery, and healthy ageing.
What daily dosage do you recommend?
Take 1 capsule (500 mg) daily with food, or as directed by your healthcare provider.
What does “Phytosome™” mean?
Indena's Phytosome™ technology (Italy) helps your body absorb plant-based nutrients more effectively. Think of it as wrapping the nutrient in a protective “bubble” of natural fats, making it easier for your cells to take in. Pure quercetin is hard to absorb; Phytosome™ improves uptake for better results.
Is quercetin safe? Any side effects?
Quercetin is generally well-tolerated when used as directed. If you are pregnant, nursing, have a medical condition, or take medication, consult your healthcare provider.
What is the best time of day to take quercetin?
Take daily with a meal for comfort and consistency. Timing matters less than taking it regularly.
