Vitamin D Deficiencies Widespread Among Pregnant Women & Infants Despite Prenatal Vitamin Usage

At a Glance

Vitamin D deficiency early in life is associated with rickets, a disorder characterized by soft bones. New research has shown that despite taking a prenatal vitamin, vitamin D deficiency is very common in pregnant women and newborn infants. Higher-dose supplementation and increased sun exposure is needed to improve maternal and infant vitamin D status.

Even among those taking prenatal multivitamin supplements, vitamin D levels were found to be insufficient or deficient in pregnant women, particularly in women living in northern regions, according to research published in the Journal of Nutrition. Researchers took blood samples from 400 pregnant women—200 African American women and 200 Caucasian women—before 22 weeks gestation and again after delivery.

More than 80% of African American women and nearly half of Caucasian women tested at delivery had levels of vitamin D that were insufficient, even though more than 90% of them used prenatal vitamins during pregnancy.

In addition, umbilical cord blood from newborns showed 92.4% of African American babies and 66.1% of Caucasian infants had insufficient vitamin D levels at birth, leaving them at risk for rickets and other health problems. A newborn relies completely on its mother for its vitamin D stores.

These results suggest that African American and Caucasian pregnant women and newborns residing in the northern U.S. are at high risk of vitamin D insufficiency, even when mothers regularly take prenatal vitamins. Higher-dose supplementation is needed to improve maternal and infant vitamin D status.

Active Calcium FAQs

1. Can my child take the Active Calcium?

  • Children 1-6 years: Not recommended
  • Children 7-10 years: 1 Active Calcium or Active Calcium Chewable
  • Children 11-12 years: 2 Active Calcium tablets or Active Calcium Chewables

It is important to provide children with a healthy, well-balanced diet high in calcium rich foods. Teaching our children to make wise food choices instead of simply eating poorly and taking a nutritional supplement is imperative to their future health and wellness. If for some reason it is not possible to supply adequate calcium from dietary sources, Active Calcium may provide a beneficial alternative calcium source for children.

2. Why is there a mixture of calcium sources in the new Active Calcium tablet?

It is now known that calcium carbonate and calcium citrate are equally absorbed and utilized when taken with food and adequate vitamin D. The amount of elemental calcium in the Active Calcium has increased from 135 mg to 200 mg per tablet. It is not possible to provide this increased amount of calcium from calcium citrate alone. Therefore, to reach a more advanced amount of elemental calcium, a mixture of citrate and carbonate was necessary.

3. Why has USANA added vitamin K to the new Active Calcium Formula?

Osteoporosis is a very costly and debilitating disease that is not considered part of the normal aging process. It is considered to be a major public health threat for almost 44 million U.S. women and men aged 50 and older. Prevention is essential to maintain optimal peak bone mass and reduce the risk of osteoporotic fractures later in life. Recent research has shown that, in addition to the other important bone building nutrients, vitamin K plays an important role in bone metabolism and mineralization. Low dietary intakes of vitamin K and low blood concentrations of circulating vitamin K have been associated with low bone mineral density and an increased risk of hip fractures in postmenopausal women. The addition of vitamin K to the new Active Calcium formula represents USANA's commitment in providing you with the very best supplement for bone health available on the market today.

4. What are the advantages of the new Active Calcium formula?

  • Clinically proven formula
  • Now contains vitamin K
  • 68% more calcium per tablet
  • 100% more vitamin D per tablet
  • Fewer tablets necessary to meet calcium requirements
  • 28 day supply for autoship convenience

Essentials FAQs

Why did Usana change the Essentials?

Nutritional science is a very fast growing and exciting field of research. As new research is published, adjustments in products are often necessary to keep current. Formulations, ingredients, technologies and labels are periodically updated and improved to account for new research, customer feedback, and changes in government regulations. We are also keenly aware that regardless of the quality, the products must also be easy to use and convenient. The new formulations have been adjusted to better represent current nutritional research and reduced in size to improve convenience.

What are the directions for using the new Essentials?

Take two (2) Mega Antioxidant and two (2) Chelated Mineral tablets twice daily, preferably with meals.

Why do I have to take four (4) Mega Antioxidant and Chelated Mineral tablets a day instead of three (3)?

In order to make the Essentials tablets easier to swallow, we have made them 3/4 the size. However, because the tablets are now smaller, the nutrient amounts per tablet have also decreased making it necessary to increase the amount of tablets required.

Will I notice any difference when I take the new Essentials compared to the old Essentials?

The new Essentials provide an overall improvement in the nutritional content. However, there should be no noticeable difference in the way that you feel when you take the new Essentials formulation as compared to the old formulation.

Can I take this new formula with my current medications?

Unfortunately, we are unable to answer any questions concerning your medications. Please check with your pharmacist, physician, or other health care professional.

Are there any precautions I should be aware of before I start taking the new Essentials?

When taking the USANA nutritional supplements, it is always important to take them with food, preferably a complete meal. Food buffers the stomach reducing the chance of G.I. upset, and enhances the body's ability to absorb certain nutrients. It is also very important to keep the body hydrated by drinking plenty of fluids every day. Fluids also help to facilitate the distribution of nutrients throughout the cells in your body.

Are there any artificial colors or preservatives used in the Essentials?

The Essentials do not contain any artificial colors or preservatives.

When is the "best time" to take my Essentials tablets?

It is always best to take the Essentials with a complete meal.

Do the new Essentials contain gluten?

The Essentials do not contain gluten.

Why did the amount of vitamin D increase?

Numerous research studies have been published within the last few years indicating that vitamin D deficiency is more widespread than previously thought. In addition, new research has suggested that to overcome these deficiencies and problems associated with a lack of vitamin D, recommended intakes should be increased significantly. Although vitamin D can be toxic in excess, new information shows that the upper limit is more than 4,000 IU per day in a person with normal vitamin D levels to begin with. This is in sharp contrast to old information published in the early 1970's on which the previous upper limit was established (2,000 IU). The new level of 600 IU included in the Essentials will help to better establish and maintain healthy levels of vitamin D when added to typical dietary intakes and sunlight. Adequate Vitamin D is very important in the prevention of many chronic health problems.

Why was the amount of vitamin B12 increased?

Vitamin B12 (cyanocobalamin), in combination with B vitamins folic acid and vitamin B6, have been shown to be important nutrients in the maintenance of normal homocysteine levels. Abnormal homocysteine levels are considered to be a risk factor for heart disease. Vitamin B12 requires a protein secreted by the stomach for proper absorption and utilization. However, due to increased intakes of certain medications (ie. antacids, acid blockers), an increasingly elderly population and other factors, actual requirements for vitamin B12 may be higher for many people than can be achieved through diet and typical supplement dosages. Since vitamin B12 is virtually non-toxic at any level, the amount provided was increased substantially to account for a greater percentage of the typical population who may not be getting enough.

Why was glutathione removed?

Glutathione is a compound that is part of one of the body's most important antioxidant systems. However, glutathione itself is not absorbed intact very efficiently. One of the best ways to increase glutathione levels in the body is to provide the building blocks and precursors needed to manufacture it within the body. N-acteyl L-cysteine (NAC) is an effective precursor to glutathione and more efficiently raises levels in the body than taking glutathione itself. Thus, we have increased the NAC levels significantly and removed the glutathione compound. We also provide substantial amounts of other important nutrients associated with glutathione such as selenium and vitamin E.

Why did the amount of copper decrease?

The copper level was decreased from 3 mg per day to 2 mg per day. This was done mainly to provide a better ratio to the existing level of zinc, and to be more in line with newer dietary recommendations.

Why does the formula contain vanadium citrate instead of vanadyl sulfate?

There is no significant difference between vanadyl sulfate and vanadium citrate as far as quality is concerned. Whenever possible we try to make our product formulations as uniform as possible for all countries. Vanadium citrate is an accepted form in more markets so it used for reasons of consistency.

Why did you decrease the Vitamin E from 450 IU to 400 IU?

Although the amount of Vitamin E as d-alpha tocopherol was slightly decreased, an additional 34 mg of mixed tocopherols (mainly gamma tocopherol) was added so that the total level of tocopherols remains basically the same.

What are Cinnamon Extract and Pomegranate Extract and how are they beneficial?

Bioflavonoids are a diverse group of naturally occurring plant compounds that exhibit a host of biological activities, most notably for their powerful antioxidant properties that complement, extend, and synergize the antioxidant activities of other nutrients making them an important nutritional component in the Essentials.

Pomegranates are a good source of antioxidants. The type of antioxidant in pomegranate is somewhat different than the compounds already in the complex, and as such, it adds to the biodiversity of the complex.

Cinnamon extract contains bioflavonoids called proanthocyanidins that are very similar to the proanthocyanidins contained in grape seeds. Again this is a new type of antioxidant in the complex. Cinnamon has been studied for its effect on increasing insulin sensitivity and help in controlling blood sugar levels.

Why did the amount of alpha-lipoic acid increase?

The amount of alpha-lipoic acid per tablet has remained at 5 mg per tablet. Because the daily dosage has increased to 4 tablets per day, the amount of alpha-lipoic acid has increased by 5 mg.

Why are you using a mixture of calcium carbonate and calcium citrate?

Calcium carbonate contains more calcium by weight than calcium citrate; by adding calcium carbonate to the formula we were able to make the tablets smaller while still keeping the same amount of elemental calcium. This mixture has been used in Usana's Active Calcium for several years.
