Vitamin D is one of the most critical vitamins for overall health and robust immunity. In the immune system, both T and B cells act as the body's first line of defense and require vitamin D. As Vitamin D3 is manufactured in the skin by direct sunlight exposure, lower levels are often associated with the cooler seasons. It is also only found in a small number of foods (predominantly animal sources). These two primary factors contribute to a common worldwide deficiency. Vitamin D is associated with increased susceptibility to immune invaders. Vitamin D levels have been shown to decline with age, due primarily to a reduction in either absorption or metabolism by the liver, decreased exposure to sunlight or a low intake of vitamin D fortified foods. Luckily, supplementation has shown to be beneficial.
Great take everyday.
Love this. So easy to take.
Really good dropper. Great quality
I love the effectiveness and can trust the quality of Equi.Life products. It's great to have this vitamin in liquid form, when my body is always so depleted of it in those winter months.
My labs showed that my D levels are great but I love the reassurance that my D levels will remain at a healthy level during the long, dark, winter months, esp living in NJ!
