Vitamin A&D-004

This product contains a balanced formula of vitamin D and calcium that promote healthy bones & teeth.

Description

Vitamin A & D provides a rich source of two fat-soluble
vitamins important for many biological and biochemical
systems of the body.
FUNCTIONS
Vitamin A is the name of a group of fat-soluble retinoids,
including retinol, retinal, retinoic acid, and retinyl esters. It
is involved in immune function, vision, reproduction, and
cellular communication. Vitamin A is critical for vision as an
essential component of rhodopsin, a protein that absorbs light
in the retinal receptors, and because it supports the normal
differentiation and functioning of the conjunctival membranes
and cornea. Vitamin A also supports cell growth and
differentiation, playing a critical role in the normal formation
and maintenance of the heart, lungs, kidneys, and other organs.
Another important fat-soluble nutrient is Vitamin D yet,
naturally present in very few foods. The active form of vitamin
D is called cholecalciferol (a.k.a. D3) and is also produce
endogenously when the skin is exposed to sunlight. Vitamin
D is well known for promoting calcium absorption, maintain
adequate serum calcium and phosphate concentrations, and
promote bone growth and remodeling. But new research
indicates that vitamin D also has other roles in the bodies
including modulation of cell growth, neuromuscular and
immune function, and reduction of inflammation. Many genes
that regulate cell proliferation, differentiation, and apoptosis
are modulated in part by vitamin D. Research indicates that a
majority of people are vitamin D deficient.
INDICATIONS
Vitamin A & D may be a useful dietary supplement for those
who wish to fortify their diet with A and D and ensure optimal
levels of these nutrients.
