Frequently Asked Questions About Isotonix® Multivitamin:
Why is taking a vitamin supplement important? A vitamin may be broadly defined as a substance that is essential for the maintenance of normal metabolic function, but which is not produced in the body and therefore must be consumed from a source outside the body. They are necessary elements in the process of converting food to energy and in the growth and repair of body tissue. Reduction of vitamin levels over extended periods can result in vitamin deficiency. These shortages may lead to symptoms which can include loss of appetite, loss of body weight, increased irri
Why is there vitamin D3 in Calcium Plus and Isotonix Multivitamin? Vitamin D3 has been added to the Calcium Plus and the Isotonix Multivitamin to facilitate the uptake of calcium. Vitamin D3 is initially activated further in the skin in the presence of sunlight and then it is activated further in the kidney and liver. Vitamin D3 is a hormone that can stimulate the production of calcium-binding proteins, which aid in transporting this essential mineral through cells. The 1,2,5-dihydroxy-vitamin D3 is then transported to critical sites in the body to facilitate calcium uptake. The intestine and bone cells are two of these critical sites. There are groups of people who are not out in the sun for significant lengths of time. Certain racial groups have significant problems in the higher latitudes, especially during the winter, in producing substantial amounts of vitamin D3 and subsequently taking up enough calcium. Even with intense phototherapy for those people requiring significant calcium nutrition, the blood levels of 1,25-OH-vitamin D3 are highly regulated.
