Flavor

Flavor isn't just about taste—it's a biological signal. When we talk about **Flavor** as a health supplement, we are usually referring to **Quercetin**, a potent plant pigment (flavonoid) found in onions, apples, and berries. It acts as nature's defense system, protecting plants from oxidative stress. When you consume it, it acts as a powerful antioxidant and anti-inflammatory agent in your body. It helps stabilize cells that cause allergic reactions (mast cells) and supports your respiratory and immune health. Think of it as the 'spice' your body needs to fight off inflammation and maintain cellular vitality.

Health Benefits & Sources

Why You Need It

Natural Antihistamine: Helps reduce allergy symptoms by stabilizing mast cells.
Heart Health: Supports healthy blood pressure and circulation.
Immune Defense: Enhances the body's response to viral infections.
Anti-Aging: Fights free radicals that accelerate skin aging.

Deep Dive

Flavor (Quercetin) works by neutralizing free radicals—unstable molecules that damage your cells. It is particularly effective in the respiratory system, where it helps relax airways and reduce inflammation. Studies suggest it can significantly shorten the duration of colds and reduce the severity of seasonal allergies. Unlike harsh pharmaceuticals, Quercetin works gently with your body's natural inflammatory response, helping you recover faster without the 'drug hangover.'

Natural Food Sources

Eating the rainbow is the best way to get Quercetin. The skin of these foods contains the highest concentration.

Food	Amount	% DV
Capers	100g (Raw)	233%
Red Onions	1 cup (Raw)	50%
Kale	1 cup (Chopped)	25%
Apples (with skin)	1 medium	15%
Blueberries	1 cup	12%

Supplementation

Dosage: A standard therapeutic dose is 500mg per day, usually split into two 250mg doses. Who is it for? Anyone suffering from seasonal allergies, high blood pressure, or looking for a potent antioxidant boost. It is often paired with Bromelain (an enzyme from pineapples) to increase absorption, as Quercetin is notoriously hard for the body to absorb on its own.

Frequently Asked Questions

No. Quercetin is a flavonoid (plant compound), while Vitamin C is an essential vitamin. They are often taken together because Quercetin helps recycle Vitamin C in the body, making both more effective.

Quercetin is difficult for the gut to absorb on its own. Look for supplements labeled as 'Quercetin Phytosome' or those that include Bromelain or Piperine (Black Pepper extract) to maximize absorption.

While some studies suggest it inhibits viral replication, it is not a cure. It supports general immune function, but you should always follow medical advice for active infections.

Unlike antihistamines that work in minutes, Quercetin builds up in the system. It may take 1 to 2 weeks of consistent daily use to see a significant reduction in allergy symptoms.

Safety & Side Effects

Quercetin is generally safe and well-tolerated. However:

Drug Interactions: It may interact with antibiotics (fluoroquinolones) and blood thinners (warfarin).
Kidney Stress: People with kidney disease should avoid high doses.
Pregnancy: There is not enough data to confirm safety; consult a doctor first.
Side Effects: High doses may cause headaches or stomach upset. Stick to recommended amounts.
