Product overview

Vitamin D3 is a nutrient that is critical to many bodily functions. Each serving provides 1000 IU of vitamin D3 which supports calcium absorption for bone health and also supports immune health, mood, and sleep. Vitamin D plays a role in most organs and systems of the body and supports the influence of chemical messengers in the immune system.

  • Maintenance support for strong bones and teeth.
  • Supports optimal immune function.
  • If you are not spending a lot of time in the sun, or eating certain foods like fatty fish, fortified milk or eggs, you may need to supplement with vitamin D3.
Take it all in

A fat-soluble nutrient, vitamin D is known as the ‘sunshine’ vitamin as our bodies can convert sunlight into Vitamin D through a process that starts in our skin. Unfortunately, many people do not get enough sunlight exposure due to many factors or they have problems with the conversion process in the body which is where supplementation with a quality Vitamin D product can be very beneficial. Doctor’s Best Vitamin D is delivered in the form of cholecalciferol, which has high-bioavailability and is well absorbed.

The vitamin D3 contained in this product is derived from lanolin, a component of sheep’s wool.
