Best Vitamin D3 2500IU for Doctor's Orders

Vitamin D is a hormone with well-established 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 homeostasis activities in the body, which is of vital importance, as calcium is involved in the functioning of all cells, although most cells require only very little of it.

Vitamin D's role in calcium homeostasis is essential, as it helps the body manage calcium levels and ensure that calcium is kept within healthy ranges in all the body's cells, tissues, and organs. The body's activated vitamin D (25-hydroxy vitamin D3) not only influences bone health but also supports immune system responses, the heart and circulation, the lungs, the musculoskeletal system, and virtually all the body's other functional systems.

Recent research has rapidly expanded our understanding of vitamin D's 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, and vitamin D is essential to ensure healthy control over calcium absorption and the availability of calcium to bone. Multiple studies have shown vitamin D's support for healthy bone structure from childhood through old age.

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.

Doctor's Best Vegan D3 features Vitashine D3, a plant source of vitamin D3 (cholecalciferol), the superior form of supplemental vitamin D. Vitamin D3 is 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, but sun protection and climate factors may influence low vitamin D3 levels.

The Vitashine D3 in Doctor's Best Vegan D3 is sustainably harvested and registered with the prestigious UK Vegan Society. Vitamin D3 is beneficial for supporting bone health, immune wellness, cardiovascular function, and for cellular gene regulation and metabolism. Clinically, vitamin D is essential to ensure healthy control over calcium absorption and the availability of calcium to bone, and multiple studies have shown its support for healthy bone structure from childhood through old age.
