Doctor's Best Vitamin D3 provides D3 (as cholecalciferol) needed for the body to regulate phosphorus and calcium levels for healthy bones, teeth and heart. 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.*

What is Doctor's Best Vitamin D3

Doctor's Best Vitamin D3 supports bone density and structure as it is required for optimal calcium absorption. More than that, this nutrient enhances and regulates immune function, supports optimal cardiovascular function and enhances cellular function. It is made of D3, the naturally-occurring form of vitamin D. Research shows that supplemental vitamin D3 (cholecalciferol) is significantly more efficient at converting to active vitamin D in the body than vitamin D2 (ergocalciferol). This makes vitamin D3 the preferred supplemental form of this nutrient. Vitamin D deficiency is prevalent with more than 75% of Americans deficient in this nutrient. People who live in the northern half of the United States are at a greater risk of being Vitamin D deficient due to a lack of sunlight.*

How does it work

Vitamin D from dietary intake or sun exposure requires two activation steps in the body. The first activation occurs in the liver, while the second activation occurs in the kidneys, allowing for regulation of calcium metabolism. Vitamin D receptors are present throughout the body, in tissue such as the skin, cartilage, heart, prostate, bones and intestines so the second activation step also takes place in local tissues. Vitamin D plays a role in most organs and systems of the body. It is hormone-like, known to interact with over 200 different genes, and plays a crucial regulatory role as a metabolic activator for a multitude of metabolic processes. It acts as a "molecular switch" by influencing the expression of multiple genes. Therefore activated vitamin D not only influences bone health, but is involved in supporting the function of the immune system, cardiovascular system, respiratory system and the musculoskeletal system.*

Why should I take Doctor's Best Vitamin D3

While best known for its role in helping absorption of calcium, Vitamin D3 has numerous benefits. 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. The 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. Doctor's Best uses vitamin D3 which is more efficient at converting to active vitamin D in the body.*

Vitamin D3 (cholecalciferol) is a nutrient that is critical to many bodily functions. Vitamin D3 is beneficial for supporting bone health, immune wellness, cardiovascular function, and cellular metabolism, among others. Mounting research is highlighting the ever-increg benefits of optimal vitamin D3 status. Vitamin D3 is known to interact with over 200 different genes and thus plays a crucial regulatory role as a metabolic activator for a multitude of metabolic processes.
