It is essential to maintain healthy
vitamin D levels throughout all stages of life, from fetal development
to old age.* Vitamin D helps protect a number of important functions in
the body.* The current recommended daily vitamin D intake is 200-600
IU, and is based on the minimum allowance to protect against bone
disease. However, an upward revision of the FDA's guideline is now
under consideration in light of new research, especially pertaining to
immune function. Cutting-edge research suggests serum vitamin D levels
should be in the range of 50-80 ng/mL 25-hydroxyvitamin D (25(OH)D).
Although direct sunlight exposure is a good source of vitamin D, many
people do not get enough sun due to season change, latitude, or
lifestyle. Therefore, vitamin D supplementation can be of great benefit
in these cases.*
Vitamin D deficiency is quite common,
particularly among the elderly.* For example, a study conducted at a
hospital in Glasgow, Scotland, found an almost universal vitamin D
deficiency among a group of 548 elderly patients. Individuals deficient
in vitamin D may need 5,000-10,000 IU of vitamin D daily to replenish
tissue stores.* Other individuals who may need higher doses of vitamin
D include the obese (the more a person weighs, the greater their
vitamin D requirements), individuals with chronic disease,
darker-skinned populations, and those with fat malabsorption.*
individuals respond well to an initial loading dose of 25,000-50,000
IUs for several days to a week, followed by lower maintenance dosing.*
With these individuals specifically in mind, Thorne's D-25,000 supplies
25,000 IU of pure vitamin D3 in each vegetarian capsule. Short-term
(2-3 days) high-dose vitamin D may also support healthy immune
Some vitamins, because of their potency, are usually
given in very small amounts. Examples of such "micro-dose" vitamins
include vitamin D, vitamin K, and vitamin B12. Most dietary supplement
manufacturers purchase "micro-dose" vitamins from raw material
suppliers as premixed dilutions, meaning the vitamins (in powder form)
are mixed with other powdered substances that in turn make it easier
for the manufacturer to handle and mix a larger quantity of raw
material. Unfortunately, the powdered substances used in these premixed
dilutions frequently contain potentially detrimental ingredients such
as lactose and also the preservatives BHT, BHA, sodium benzoate, and
At Thorne Research, our promise is to give you the
purest supplements humanly possible. Therefore, we do not purchase
premixed dilutions of any "micro-dose" vitamins. Instead, we purchase
pure, undiluted vitamins and create our own dilutions when it is
necessary to do so, using pure, hypoallergenic powders, such as
magnesium citrate or plant cellulose. The resultant premixture is then
added to the dietary supplement being made, ensuring the proper amount
of each pure nutrient is contained in each capsule.
