Bioflavonoids such as quercetin play important roles in immune health. They’re not only essential for proper utilization of vitamin C, but they also provide powerful antioxidant support themselves. Quercetin has been shown in laboratory tests to help defend the body against seasonal viruses such as cold and flu.

Vitamin C

Vitamin C helps strengthen our first line of defence against invading pathogens: the epithelial barrier that lines the nose, throat, eyes, and airway passages. Vitamin C also supports the action of immune system cells to help keep us healthy year-round.

Organic Echinacea Extract & Anti-Viral Formulas

Natural Factors Anti-Viral contains ECHINAMIDE®, the only standardized extract of  Echinacea purpurea shown in placebo-controlled clinical trials to reduce the duration and severity of upper respiratory infections. Anti-Viral contains a proprietary blend of ECHINAMIDE, lomatium, astragalus, reishi, and licorice. Modern science has confirmed that each of these herbs enhances the immune system’s response to viral infections.

ECHINAMIDE® The Best Echinacea Extract

Not all echinacea products are created equal. Here at Natural Factors, we use our own patented extraction technique to create ECHINAMIDE – made from certified organic echinacea grown on Factors Farms® in BC’s Okanagan Valley. Our unique process of extraction guarantees the bioavailability of the three known plant actives in Echinacea purpurea: alkylamides, cichoric acid, and polysaccharides.

Oil of Oregano

Oregano encourages a strong immune response, particularly when it comes to respiratory health. Natural Factors’ Oil of Oregano is organic, handpicked, and wild crafted. It provides a minimum of 80%  carvacrol, the key active ingredient in clinical studies.

Vitamins A & D

Vitamin D plays a major role in the immune system. Low vitamin D levels increase susceptibility to infections.

Often overlooked for immune health, vitamin A is crucial for maintaining a strong epithelial barrier in the nose and airways, which helps protects us from airborne viruses.

Whole Earth & Sea Super Mushroom

Mushrooms, such as reishi and shiitake, have long been prized for their immune-supportive benefits. Super Mushroom features these along with Wellmune® beta-glucans, clinically shown to reduce frequency and severity of seasonal upper respiratory infections (URTIs).
