Vitamin D3 5000 IU

Vitamin D3 is beneficial for maintaining bone health, immune wellness, circulatory function, and cellular metabolism, among others. Mounting research is highlighting the ever-increasing 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.

While we obtain some vitamin D from our diet, the major source for replenishment of vitamin D levels is exposure of the skin to sunlight. Adequate daily sun exposure is considered to be sufficient to fulfill the human requirement for vitamin D. However, a number of factors affect our ability to refresh our vitamin D supplies. First, due to the climate we live in, sun exposure is not always possible year-round. This is the case especially in northern latitudes and much of the northern United States. Second, direct sunlight exposure on the skin is needed for vitamin D production to occur. Covering skin with sunscreens and other topical products may keep the necessary exposure from occurring. Skin color is also a factor when it comes to adequate vitamin D production. Individuals with darker skin require longer sun exposure than individuals with lighter skin to produce the same amount of vitamin D. Furthermore, UV rays from the sun do not penetrate indoors through windows. Since UV light is required for vitamin D synthesis in skin, being indoors leads to no production of vitamin D. For one or more of these reasons, we often fail to meet our vitamin D requirements for health.
