Just as exercise keeps our bodies in shape, there are things we can do to keep our immune system in top condition during the winter months and beyond. Simple steps such as eating a healthy diet and getting enough sleep are important, but not always enough to ward off the many cold and flu bugs synonymous with the winter months. ImmiFlex contains a unique immune enhancing ingredient called Wellmune®, as well as vitamin D3, another nutrient with documented immune supporting benefits. Wellmune® is a unique research proven beta glucan compound that is protected by 40 patents and patents pending, and is derived from a purified inert yeast which is known not to contribute to or worsen yeast infections such as Candida albicans. Wellmune® targets and primes specific innate immune cells to enhance the immune system, and has been clinically proven to help prevent cold and flu and defend against infection.
