Product Type : Food Supplement

Inspired by the Zelenko Protocol, this vitamin, flavonoid and elemental zinc complex works synergistically to support the body’s innate and adaptive immune system.

Vitamin C supports various cellular functions of our natural immunity. It is essential to provide Vitamin C via our daily food intake as we do not make it ourselves.

Vitamin D3 stimulates the initiation of white blood T cells which play a central role in the adaptive immune system’s response to the invasion of antigens (foreign substances) in the body.

Quercetin helps Zinc pass through cell walls into the interior of the cells where it affects how they respond to infections, also helping to control inflammation.

Promotes overall immune health.
