Natures Plus Vitamin D3 1000iu: Studies suggest that cholecalciferol (D3) is the most bioavailable form of vitamin D, which has recently been the subject of renewed interest amongst nutritional scientists. A raft of new studies highlight the importance of Vitamin D, not only in its traditional role in bone support, but also in areas including immune and mental health.
Vitamin D is unique among essential nutrients, in that it is a vitamin that transforms into a hormone. Once ingested, vitamin D converts into a metabolite called 25-hydroxycholecaliciferol [25-OH-D3] in the liver, after which it converts into its active form 1,25 dihydroxycholecalciferol hormone, and like other hormones, it functions as a chemical messenger functions. Once it is produced in the kidney, the active form of vitamin D triggers several essential processes including:
(a) Mobilisation of calcium and phosphorus from bone tissue
(b) Absorption of calcium and phosphorus form food
(c) Thyroid and parathyroid function
(d) Nerve function
(e) Immune function
