Our immune system functions best when supported by consistent habits, including sleep, nutrient intake, and antioxidant support. This protocol pairs two ingredients commonly included in wellness routines designed to help the body respond to daily stressors and changing environments.

Quercetin Bioactive delivers a highly absorbable form of quercetin, a plant flavonoid often chosen for immune balance and histamine awareness. Vitamin C Complete offers liposomal vitamin C from Quali-C™, along with citrus bioflavonoids to support cellular health and antioxidant replenishment. Together, these products provide a streamlined daily foundation for immune-aware living.

1 months supply:

Quercetin Bioactive (60 capsules)
Provides Quercefit®, a quercetin extract combined with sunflower lecithin using Phytosome™ technology for improved absorption. Often used in routines focused on histamine regulation and antioxidant balance.

Vitamin C Complete (60 capsules)
Delivers Quali-C™ ascorbic acid in a liposomal format, enhanced with citrus bioflavonoids for broad-spectrum antioxidant coverage. Known for its role in tissue repair and daily immune function.

Opti-Vita Complex (60 capsules)
A comprehensive multinutrient formula including Oxxynea® polyphenols, liposomal vitamins, minerals, and Bio-Enhanced® R-alpha-lipoic acid. Often selected as a nutritional foundation.

COMPLEMENTARY PRODUCTS

Take both with breakfast for consistency and comfort. Vitamin C Complete pairs well with a small amount of fat (e.g., yogurt or nuts) to support liposomal delivery, while Quercetin Bioactive is best taken with food to minimise any digestive sensitivity.

Yes, these formulas are intended for daily use. Many users maintain the routine throughout the year, then reassess seasonally based on travel, weather changes, or personal wellness goals.

No, taking both together simplifies your routine. If you prefer, split the dose: Vitamin C Complete mid-morning and Quercetin Bioactive with lunch, as long as each is paired with a meal.

Some people find Quercetin easier on digestion when taken with a meal. If you notice mild discomfort, simply pair both supplements with your main meal.

Many begin at the first signs of seasonal changes or increased exposure—during travel, busy periods, or colder months. It’s also used proactively for daily wellness.

Yes, these products integrate smoothly into most supplement stacks. Just watch for duplicate ingredients (e.g., additional vitamin C) and adjust timing if needed.

This routine is formulated for adults.

For younger individuals, please consult a healthcare provider for age-appropriate guidance.
