*These statements have not been evaluated by the Food and Drug Administration. This product in not intended to diagnose, treat, cure or prevent any disease. Doctor’s Best Vegan D3 features Vitashine D3, a plant source of vitamin D3 (as cholecalciferol), needed for the body to regulate phosphorus and calcium levels for bones, teeth and heart protection. Vitamin D3 is produced in the skin by absorbing the sun’s UV rays and is obtained from food in limited amounts. Sun protection and climate factors may influence low Vitamin D3 levels. Vitamin D3 is beneficial for immune, cardiovascular, bone density and structure, and cellular function. It plays a role in most organs and systems of the body and influences the chemical messengers of the immune system.* Helps regulate calcium and phosphorus levels needed for bones and teeth*Helps support immune system and heart*Vegan plant sourced Vitamin D3* Use of sunscreen, limited time in the sun and skin color are factors that make getting sufficient Vitamin D from the sun challenging.*Doctor’s Best uses Vitamin D3 which is more efficient at converting to active Vitamin D in the body.*Vitamin D supports a balanced immune response and keep the immune system in a normal state of awareness.* Vitamin D regulates calcium homeostasis in the human body, which is of vital importance as calcium is involved in the function of all cells. Calcium balance is also essential for bone growth and formation, as well as for the function of the nervous system. Vitamin D has been shown in multiple studies to support bone structure. Over the last several years research has focused on critical functions of this vitamin and the role it plays in most organs and systems of the body. Vitamin D deficiency is prevalent with more than 75% of Americans deficient in this nutrient. A major source of Vitamin D is sunlight but use of sunscreen, limited time in the sun and skin color are factors that make getting sufficient Vitamin D from the sun challenging.

Vitamin D has well-established hormonal effects, and like other hormones it can act as a "molecular switch" by influencing the expression of multiple genes. One of its major hormonal effects is to regulate calcium's homeostasis activities in the body. This is of vital importance, since calcium is involved in the functioning of all cells but most cells require only very little of it. Vitamin D helps the body manage calcium homeostasis (keep calcium within healthy ranges in all the body's cells, tissues and organs). Vitamin D research has rapidly expanded into exploring its diverse roles in human health. Vitamin D's clinically proven bone benefits are directly related to its management of calcium homeostasis and specifically to calcium balance in bone. Calcium balance is essential for bone growth and formation. Vitamin D is essential to ensure healthy control over calcium absorption and the availability of calcium to bone. Multiple studies have shown its support for healthy bone structure from childhood through old age. The body's activated vitamin D (25-hydroxy vitamin D3) not only influences bone health but helps support immune system responses, the heart and circulation, the lungs, the musculoskeletal system and virtually all the body's other functional systems. It is increasingly becoming clear that optimal vitamin D status may have beneficial impact on longevity. In a recently published prospective study of thousands of elderly men in Sweden, Hong Kong, and the USA, a significant association was found between healthy blood 25(OH)D levels and a healthy lifespan. Recent research also suggests the prevalence of subclinical vitamin D deficiency is increasing worldwide, and this is paralleled by an increasing number of overweight individuals. It has been proposed that being overweight may contribute to lower blood 25(OH)D levels because the storage of vitamin D in adipose tissue decreases its bioavailability.
