Although science shows that older people have lower vitamin C levels, the exact cause of this unfortunate phenomenon is not completely clear.
One theory is that our need for antioxidant activity increases with age due to higher levels of oxidative stress. Vitamin C is a dynamic, avid free radical scavenger that increases antioxidant activity in the body not only by fighting reactive oxidative species (ROS) on its own, but also regenerating other antioxidant powerhouses (e.g., glutathione and vitamin E).* Like vitamin C, our body stores of “master antioxidant” glutathione also decline with age. This decrease in antioxidant activity levels means that there is a greater need for antioxidants to fight ROS.
While knowing vitamin C levels is important for people of all ages, increasing vitamin C intake through diet and quality supplementation can both restore glutathione and maintain healthy antioxidant levels, which is especially beneficial for the elderly. optimizing practices should ideally be a daily consideration (and effort).
Another theory is that vitamin C absorption is less efficient in our later years (though not always effective for younger people either). Taking a bioavailable vitamin C supplement known to impact the cellular actions of vitamin C can ensure you both absorb, retain, and fully utilize the essential vitamin so it can support brain longevity. and whole body (among other amazing health benefits).*
