This guarantees purity from mercury, lead, PCB’s and other contaminants. Independent microbiological testing is also performed to ensure supplement purity and safety.
 
Bioavailable:
 
The bioavailability of nutritional supplementsis an often-overlooked factor. Bioavailability basically means “the proportion of a nutrient or bioactive ingredient that was absorbed from the gastrointestinal tract” for use or storage in the body. After passing through the intestinal wall lining, the ingredients enter your bloodstream and find their way to their target organ or body system where they go to work performing their specific dutiesto support your health and make you feel great.

What is Vitamin D?

Vitamin D works synergistically with vitamin A, preferring a 7:1 ratio. It plays a role in absorbing and regulating calcium and phosphorus. It also helps build strong bones, teeth and skin. It is vital to the health of the nervous system and kidneys.

It can be derived from the sun’s action on oils secreted and reabsorbed by theskin. But the more tanned the skin, the less it is absorbed. Also, the older the skin, the less active it is in producing vitamin D. This vitamin helps the body synthesise protein and incorporate magnesium into bone/teeth structures.

Benefits of Vitamin D:

Bone Health: The minerals calcium and phosphorus form a large part of the substance hydroxyapatite, which makes up over half of our bonecomposition. Two substances, however, primarily regulate the body's use of calcium and phosphorus: parathyroid hormone (PTH) and vitamin D. PTH triggers the release of calcium from our bones into our bloodstream when levels drop too low.

Vitamin D, on the other hand, prevents PTH from drawing too much upon our bones' supply of calcium by helping our intestines absorb more calcium and by allowing ourkidneys to hold onto more calcium. By regulating our PHT function, vitamin D not only protects our bone health, but also fights against too much calcium in our bloodstream that can cause cardiovascular problems.

Immunity: Vitamin D plays a crucial role in our immune system by triggering macrophage cells that release antibacterial proteins. These proteins are shown to possibly prevent infections,including Mycobacterium tuberculosis (responsible for tuberculosis) and Mycobacterium leprae (responsible for leprosy).

Blood Pressure: Vitamin D may help to manage our blood pressure by monitoring the system that increases our blood pressure when it gets too low, called the renin-angiotension system. Our body needs a healthy dose of vitamin D to inhibit this system from raising our blood pressuretoo high.

Insulin: Vitamin D regulates the levels of PTH from releasing too much calcium into the bloodstream. An overdose of PTH in our bloodstream can also cause fat cells to collect too much calcium, triggering the cells to produce too much cortisol, a hormone that counteracts the effect of insulin, making it difficult for the body to metabolise sugars.

Furthermore, when too much calciumcollects, our cells stop producing GLUT-4, a protein that helps transfer sugar into the bloodstream and to our cells. GLUT-4, however, functions only when triggered by insulin. Without sufficient vitamin D, not only do our bodies produce too little GLUT-4 to transport the necessary sugar to our cells, but also lacks the effectiveness of insulin to stimulate that process.
