Frequently Asked Questions

Q: What is the best form of quercetin to take?

A: For superior absorption, Quercetin Phytosome® (quercetin bound to phospholipids) is clinically proven to have the highest bioavailability. A close and more accessible alternative is Quercetin Dihydrate, the standard, well-researched form. Avoid plain “quercetin” without a specification, as it may be less absorbable.

Q: How to take quercetin powder?

A: Mix the recommended serving (typically 500-1000 mg) with a beverage. For best absorption, take it with a source of fat (like a spoonful of oil or with a meal) and/or with Vitamin C or Bromelain, as these can enhance its bioavailability and effectiveness.

Q: Which is better, CoQ10 or quercetin?

A: They are not competitors; they are a powerful team with different primary roles:

• CoQ10: Essential for cellular energy production (especially in the heart and muscles) and acts as a fat-soluble antioxidant.

• Quercetin: A potent anti-inflammatory and antiviral flavonoid that also supports immune function and acts as a water-soluble antioxidant. For comprehensive cellular and cardiovascular health, taking them together is ideal.

Q: Which food is highest in quercetin?

A: Capers and raw elderberries are among the absolute richest sources. Other excellent dietary sources include:

• Onions (especially red and yellow)

• Kale

• Broccoli

• Apples (with the skin)

• Berries

Q: What are the symptoms of low quercetin?

A: There is no official “deficiency” for quercetin like there is for vitamins. However, a diet consistently low in flavonoids like quercetin may contribute to:

• Increased susceptibility to inflammation

• Weaker antioxidant defense against oxidative stress

• Less robust immune response Ensuring adequate intake through diet or supplements helps support the body’s natural resilience in these areas.
