Ingredient story:

Wellmune® is a natural beta glucan which is highly purified from the cell wall of a proprietary baker’s yeast. Taken daily, Wellmune® has been shown in over 12 human clinical trials to support a healthy immune response. It is absorbed by the lymphatic tissue in the intestine known as Peyer's Patches.

Clinical benefits have been shown to take effect within two weeks. Research shows that Wellmune® also helps reduce the incidence of upper respiratory tract infection symptoms and improve an overall sense of well-being in people of all ages experiencing physical or lifestyle stress.

  • Supports a healthy immune system + response
  • Supports the body's immune cell function
  • Helps strengthen the immune system

Sleep + Immunity contains 250 mg of Wellmune®, a dosage at which clinical benefits have been shown.
