Key Benefits: Ester-C® vitamin C stays in the body longer than standard vitamin C forms and is able to provide 24-hour immune support. B vitamins are water-soluble nutrients that play a key role in maintaining nervous system health, psychological wellbeing and energy production. B vitamins, like vitamin B6 and B12 also support healthy immune system function. Zinc is an important trace mineral that supports a healthy immune system. It maintains the skin barrier and ensures development and function of immune cells involved in the non-specific immune response. Vitamin C contributes to the normal function of the immune system, protection of cells from oxidative stress and energy-yielding metabolism. Vitamins B6 and B12 contribute to normal immune system function. Magnesium contributes to electrolyte balance.
