This vitamin D3 100 supplement by Metagenics features high potency vitamin
D3—the most bioactive form of supplemental vitamin D.
Supplies high levels of vitamin D, which is important for maintaining
healthy bone strength and immune function. Available in easy-to-swallow
microtablet delivery form.
The Importance of Vitamin D
Despite all of the medical advances we have made in this century, Vitamin D3
deficiency is a growing epidemic. It only takes about 15 minutes of sun exposure
for the body to manufacture about 10,000 IU of vitamin D3 – but most people
aren’t even getting this much exposure. Because of changes to the ozone layer,
skin cancer has become a very real concern. Fear of melanoma has people staying
out of the sun or covering up with sunscreen, which also blocks vitamin D3
production. Think about what would happen to your houseplant if you starved it
of light: it would die. Much like plants, we depend on the sun’s rays to keep
our bodies healthy. If that isn’t possible, we must supplement with vitamin D in
order to stay healthy.
But this vitamin often plays double duty. It acts as an essential vitamin
when it binds with calcium to aid absorption, but it also acts as a hormone.
Vitamin D Deficiency
Recently, there is a great deal of research being done on this “sunshine”
vitamin. A deficiency of vitamin D3 has been implicated in such conditions as
type 2 diabetes, obesity, depression, high blood pressure, chronic fatigue
syndrome, fibromyalgia, psoriasis, kidney stones, osteoporosis and Alzheimer’s.
Many researchers also believe that an extreme deficiency that is left unchecked
may even lead to cancer of the prostate, breast or colon.
Vitamin D3 is also very involved in immune system function, which may be how
it can reduce the risk of cancer and autoimmune diseases. It is also believed to
improve mood, protect the brain from toxicity and increase neuromuscular
function. If you don’t have enough vitamin D in your system, your body will not
be able to absorb calcium and that can lead to various bone disorders, including
Lack of sun exposure is the most common reason for a D3 deficiency in the
United States today, but we are also lacking vitamin-D-rich foods in our diet,
such as cold water fish like wild salmon, sardines and mackerel.
Other foods, such as cereal and milk, are supplemented with vitamin D, but
this doesn’t have a substantial increase on blood vitamin D levels. This may be
because the food manufacturers rely on a poorly absorbed form of vitamin D known
as ergocalciferol (a form of vitamin D2). To keep your vitamin D3 levels
adequate, you may supplement with vitamin D3, such as the D3 1000 found in these
tablets by Metagenics.
Testing for a Vitamin D Deficiency
Visit your doctor for a blood test to check your vitamin D3 levels. The test
to request is called 25(OH)D. Although some guidelines say you need 30 ng/ml of
vitamin D in order to have sufficient levels, many recent studies indicate that
80 ng/ml is ideal for keeping your bones healthy and allowing vitamin D to
perform its function throughout the body.

Megagenics D3 1000 is a great product!
By Geri from Maine on March 19, 2011
I first became familiar with this product thru a chiropracter and began using the 5000 strength last spring. Up here in the Northeast USA, many folks have Vitamin D deficiencies because of long winters and lack of time in the sun without being bundled up with warm clothing. I definitely noticed this passing winter season that I was not depressed like I am most winters; we had snow storm after snow storm, but my "cabin fever" was not that bad; I actually enjoyed being in the house crocheting and organizing my photos. Recently, I've switched to the 1000 formula because my vitamin D level is in the healthy range.
Convenient. No taste. Very easy to swallow.
I would recommend this item to a friend.
