Jackie takes 10,000 units of vitamin D(3) per day as a gelcap.
Her starting 25-hydroxy vitamin D blood level was 18.1 ng/ml. Severe deficiency, no surprise.
On her 10,000 units per day, Vitamin Shoppe brand, her 25-hydroxy vitamin D level was 76.2 ng/ml--perfect. It stayed in this range for about two years.
She then changed to the Nature Made brand gelcaps she picked up at Walgreen's. Repeat 25-hydroxy vitamin D level: 23 ng/ml.
This has now happened with five different people, all taking the Nature Made brand.
If you are taking this brand of vitamin D, please be on the alert. You might consider a 25-hydroxy vitamin D blood level to be sure it actually has the vitamin D it's supposed to have.
Or, change brands.

Dear William Davis, MD:
We recently received your e-mail regarding Nature Made products. We regret to
hear that the quality standards of our company. [?]
Our company is called Pharmavite, and we manufacture Nature Made nutritional
supplements. We have been in business since 1971. We are committed to quality
control, and have very high quality standards. Our Quality Control personnel
sample and test all raw materials as they enter our plant, and again assay the
finished product, before final packaging.
Dietary Supplements are regulated under the FDA through DSHEA (Dietary
Supplement Health & Education Act of 1994). The United States Pharmacopoeia
(USP) establishes standards for the composition of drugs and nutritional
supplements. This voluntary non governmental organization was set up in 1820
and has officially been recognized by federal law since 1906. Standards
established by USP for products are legally enforceable by the FDA. At
Pharmavite we participate in the USP Dietary Supplement Verification Program
(DSVP). Many of our products have earned the DSVP seal and additional products
are currently being evaluated. Our DSVP certified products will have the DSVP
seal on the product label.
Our Nature Made Vitamin D 400 IU tablets have been reviewed by the USP and bears
the DSVP symbol on the label. Although the USP has not reviewed all of the
Nature Made Vitamin D supplements, all of our products go through the same
rigorous quality testing at Pharmavite. The products which have earned the seal
help us to demonstrate the high quality of our products.
We would like to look into the product(s) your patients have been using. If you
could provide the UPC and lot numbers of the product(s), we will be happy to
review our records. In addition, if you would like us to test the product(s)
that you currently have, we will be pleased to send a prepaid postage mailer so
you may return the product(s) to us so that our Quality Control Department can
examine it. Please let us know if you would like us to send you the prepaid
We thank you for contacting us and hope that you will continue to use and enjoy
Nature Made products with complete confidence.

I take a lot of vitamins, and I have some Nature Made vitamins that I take: Triple Omega, Magnesium, and B12.
How do I know if these are no good?

There are two typys of vitamin D(3).
Vitamin D is an hormon and it works like an On/Off switch in a way .
You have .25-Vit-d(3) which is like an OFF switch to your immune system, and you have 1.25-Vit-d(3) which acts like an ON switch for your Immune System..Or viseversa.. cant remember which is On or Off...
