Description
Keep your immune system working at its best with four of our most potent immune support supplements: Artemisinin, Vitamin D3 + K2, Quercetin, and Zinc Picolinate. All four of these supplements work in tandem to support a healthy immune system:
Artemisinin- A compound extracted from Sweet Wormwood, Artemisinin has become a popular herbal supplement for immune support and longevity due to its ability to support cell repair.
- Vitamin D3 + K2 - Vitamin D3 is a fat-soluble essential vitamin synthesized by the skin when it is exposed to sunlight. Vitamin D is one of the essential vitamins most associated with proper immune function and those who are deficient are more at risk for symptomatic infections. Vitamin K2 is included as well to help the D3 be properly absorbed and to prevent short-term hypercalcemia.
- Quercetin - Quercetin is a heavily researched bioflavanoid found in many fruits and vegetables. It works as a potent antioxidant which has been found to support immune health. Quercetin is best taken with Zinc due to its function as a Zinc Ionophore it helps increase intracellular Zinc levels.
- Zinc Picolinate - Zinc is an essential mineral which is used in countless bodily processes including immune support. Zinc is known to help inhibit viral replication when present inside cells so use of Zinc along with a Zinc Ionophore such as Quercetin can help increase its effectiveness in immune support by boosting Zinc levels inside one’s cells.
