Is it safe to use USANA’s Vitamin D product AND the Essentials or HealthPak?

In recent years, many studies have reported that vitamin D deficiencies are surprisingly common worldwide, especially during winter months. As such, many doctors and health professionals have advised supplementing with vitamin D at levels between 2,000 IU and 5,000 IU (where the exact level depends on the individual, his/her location, and health history).

USANA‘s Vitamin D product is intended to supplement the dosage contained in the USANA Essentials and USANA HealthPak for those who require more than what those products provide.

Most experts agree that normally healthy individuals can safely take this amount of vitamin D without incident. If you are concerned about adding more vitamin D to the level contained in the Essentials or HealthPak, we advise you to consult with your physician who can order specific tests if necessary. Otherwise, USANA‘s Vitamin D product will be a valuable option for the many individuals who have insufficient levels and cannot get enough vitamin D from multivitamins products alone.

Can children use USANA‘s Vitamin D product?

USANA‘s Vitamin D product is not formulated or labeled for use in children under the age of 18. While vitamin D supplements can benefit children under certain circumstances, we are unable to make recommendations outside label directions and can only suggest consulting with a child’s healthcare provider for further information.

How much vitamin D does USANA‘s Vitamin D product provide?

United States

The U.S. Vitamin D product provides 2000 IU (50 mcg) of vitamin D per tablet.


The Canadian Vitamin D product provides 1000 IU (25 mcg) of vitamin D per tablet.

Why does USANA’s Vitamin D product contain a warning about blood tests?

USANA’s Vitamin D product provides the following warning on its label:

“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 2000 IU/d for vitamin D intake, regular blood tests for vitamin D and calcium status are suggested.”

In addition to the standard dietary supplement warning, the warning about blood tests is a general warning added as a precaution.

There has never been a clinically documented case of vitamin D toxicity below 30,000 IU. However, the official upper limit for vitamin D is currently set at 2,000 IU, and as a company we feel it is our duty to promote awareness and education among our customers.

Unfortunately, there are many people who may take dietary supplements without thought of excess or who may not wish to follow label directions. We have included this additional warning because while vitamin D deficiencies are widespread, vitamin D products are not something that should be taken without regard to safety.

As stated before, adding in a factor for safety, most experts agree that 10,000 IU or less can be taken safely by normally healthy individuals. If someone has concern about safety, is regularly exposed to unusual levels of sunlight, or wants to be absolutely certain of their vitamin D blood levels, we suggest getting vitamin D levels checked before taking large supplemental levels of vitamin D. (Please note that this is not generally necessary, however, when consuming the recommended dosages of the USANA HealthPak or USANA Essentials, USANA Active Calcium, and USANA BiOmega.)

Why has USANA’s Vitamin D product changed color?

Instead of a gray appearance, USANA‘s Vitamin D product tablets are now off-white with possible tan spots. This change is the result of a new supplier for the vitamin K raw material used in this product. No other changes have been made, and the potency is still the same for all active ingredients in the tablet.

The change only affects markets that have vitamin K in the product (currently the US, UK, and the Netherlands).
