Frequently Asked Questions About USANA Vitamin D

  1. How many tablets of Vitamin D can I take per day?
    USANA recommends you only follow the suggestions given on the product labels. Whatever the serving size is mentioned there, take that. However, if you feel that your body does not have enough Vitamin D and you require more, consult your healthcare professional. Whatever they recommend, follow that. Do not exceed the dose without proper consultation.
  2. Why is there a warning about blood tests on USANA’s Vitamin D product?

You might have come across the warning label on USANA’s Vitamin D product. It reads as follows:

“Keep out of reach of children. Consult your physician if you are pregnant, nursing, taking a prescription drug, or have a medical condition. If you exceed the established Upper Limit (UL) of 100 µg (4,000 IU/d) for vitamin D intake, regular blood tests for vitamin D and calcium status are recommended.”

It is noteworthy that all products should come with warnings. Therefore, USANA includes a standard dietary supplement warning. In addition, there is a recommendation regarding blood tests that tends to raise concern in our customers. However, it must be noted that it is a precautionary warning.

There hasn’t been a single clinically documented case of Vitamin D toxicity of dosage below 30,000 IU. However, there is an established upper limit which is set at 100 µg (4,000 IU) per day. As a company, we feel obligated to spread awareness and educate our customers.

Unfortunately, many people tend to take dietary supplements casually. They do not take care of the quantities and without thought tend to take it in excess. Whether they do not read the labels or for other reasons they take in excess, we have included an additional warning. Since Vitamin D is important and deficiencies are common, the products supplementing Vitamin D should not be taken without safety measures.


If someone wishes to be absolutely certain about their Vitamin D blood levels or is concerned about their safety, or if they are exposed to unusual levels of sunlight regularly, we suggest they should get a Vitamin D test before taking any large supplemental level of Vitamin D

  1. Can vitamin D supplements interact with any prescribed drugs?
    The warning label on USANA’s Vitamin D suggests consulting your healthcare provider if you are on prescribed drugs. Certain types of medications such as steroids and cholesterol-lowering drugs have the potential to interact with Vitamin D supplements.
    Therefore, if you are on medication, you should first discuss it with your professional healthcare provider and then use the recommended amount.
  2. How many IU’s are there in micrograms?
    1 microgram of Vitamin D contains 40IU of Vitamin D. therefore if you wish to convert, simply multiply the number of micrograms, also written as mcg or μg by 40.
  • 1 microgram (μg) vitamin D = 40 IU vitamin D. For example: 50 mcg vitamin D = 2,000 IU vitamin D (50×40= 2,000)
