Canker-S+™ is a dietary supplement formulated to promote mouth health, immune health, and the relief of canker sores. Canker S™ is available in capsules from Natura-Genics®.

How It Works

Canker-S™ contains a powerful combination of l-lysine, B vitamins, vitamin C, zinc, and deglycyrrhizinated licorice. L-lysine is an essential amino acid that your body needs but cannot produce on its own. It is necessary for various bodily functions and must be obtained through diet or supplements.

Benefits of Canker-S™

  • Promotes mouth health
  • Promotes relief of canker sores
  • Supports reduced risk of developing new canker sores
  • Supports immune response

Promotes Mouth Health

Individuals who are looking to take some additional steps for mouth health may find support from Canker-S. Some studies have shown that licorice contains compounds that support teeth and mouth health. The two main compounds in licorice, licoricidin and licorisoflavan A, are believed to promote teeth health by inhibiting the growth of cavity-causing bacteria.

Promotes Relief of Canker Sores

The development of canker sores in the mouth or at the base of the gums is often accompanied by pain and discomfort. To promote faster healing of canker sores, many people turn to deglycyrrhizinated licorice which is commonly found as a mouthwash. L-lysine has also been shown to aid in both the quick healing and prevention of canker sores. Additionally, studies have revealed a potential correlation between recurrent canker sores and lower levels of vitamin B12 and folate.

Promotes Immune Health

Having a strong immune system offers numerous benefits to your body. Vitamin C specifically helps stimulate the production of white blood cells, which are essential in defending your body against infections. Moreover, its antioxidant properties assist in enhancing the functionality of white blood cells while safeguarding them against potential harm from harmful molecules such as free radicals.
