VITAMIN D "THE SUNSHINE VITAMIN"...
Sometimes referred to as the “sunshine vitamin”, vitamin D is mainly
produced in your skin in response to sunlight. Vitamin D is a fat-soluble
vitamin in a family of compounds which include vitamins D1, D2 and D3 –
affecting as many as 2000 genes in the body. NOW’s Vitamin D3-1000 offers
the required dose of this vitamin to those who can’t be outside everyday
catching some rays! As more of us avoid any serious sun exposure,
supplementing with NOW Vitamin D3-1000IU becomes necessary to ensure your
body is receiving the amount it needs.
Uses and Benefits
Vitamin D serves many functions.
Most importantly, vitamin D helps in regulating the absorption of calcium
and phosphorus, and facilitating normal immune function. Getting a
sufficient amount of this vitamin is vital for normal growth and development
of bones and teeth, as well as improved resistance against certain disease.
If your body is not getting enough vitamin D, you’re at risk of developing
bone abnormalities like osteoporosis.
We are understanding more and more the importance that vitamin D is playing
in supporting immune function. Vitamin D has the ability to modulate the
immune response, rather than simply strengthen it. In cases of immune
dysregulation (autoimmune disorders, cancer, psoriasis) it serves to balance
the response, therefore decreasing the dangerous over-reaction to our own
cells and tissues that is seen in many of these conditions. The fat soluble
vitamin has been shown to dramatically stimulate the expression of potent
anti-microbial peptides, which exist in neutrophils, monocytes, natural
killer cells, and in epithelial cells lining the respiratory tract.
The “D-ficiency” and Osteoporosis
The bone matrix is of normal
composition but decreased amounts because more bone is being broken down
than is being produced. Testosterone and estrogen maintain bone density by
promoting bone building and slowing bone removal. This is one reason why
bone density decreases as we age.
There are a multitude of minerals that form the matrix of the bone.
Deficiency in any one of these nutrients can lead to bone loss. Vitamin D
helps bring calcium into the bone. It is one of the fat-soluble vitamins
that are poorly absorbed through the digestive process as we age. In areas
away from the equator, skin production of vitamin D is limited during
certain times of the year. Eating vitamin D rich foods like fish and egg
yolks, and taking vitamin D supplements like NOW Vitamin D3-1000IU, will
preserve bone density.
Meet Your “D” Needs
Some studies suggest that considerably higher amounts of
vitamin D – as much as 2000IU – are needed to preserve bone strength as we
age, and that people over the age of 50 generally need higher amounts of
vitamin D than younger people do. Although the exact dosage may
differentiate from person to person, the overall importance of vitamin D to
the body does not. So while you’re catching some rays this summer, think
about supplementing with NOW’s Vitamin D3-1000, and ensure you are meeting
your “D” needs!
