Do the Essentials contain gluten?

No, the Essentials do not contain gluten.

Why was glutathione removed from the Essentials?

Glutathione is a compound involved in 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 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 production, including selenium and vitamin E.

What are the Essentials?

The Essentials are USANA's flagship product: a supplement combining both the Mega Antioxidant and Chelated Mineral products.
 
Formulated to not only prevent deficiency diseases, the Essentials provide the necessary micronutrients to retain optimal health and energy levels that everyone, at every age, needs every day. The Essentials also contain trace minerals, mixed carotenoids, bioflavonoids, and other phytochemicals and antioxidants to provide a full arsenal of compounds to help protect against daily exposure to free radicals.

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

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.

If I am allergic to iodine, can I take the Essentials?

Iodine is a constituent of the thyroid hormones thyroxine (T4) and triiodothyronine (T3) and is an essential mineral in human nutrition. Iodine deficiency results in syndromes known as Iodine Deficiency Disorders (IDD), and in the case of extreme deficiency, goiter. Deficiency of the thyroid hormones has many effects, including thyroid gland enlargement, congenital and developmental defects, poor growth, and mental retardation.
 
Except for rare instances of hypersensitivity to iodine (note that this is not the same as an allergy), humans are remarkably tolerant to high intakes of iodine. However, excessive supplementation (at least 2,000 mcg per day) of iodine may cause or exacerbate acne in some individuals. Kelp as a dietary supplement or fast foods containing high levels of iodized salt may deliver sufficient iodine for this adverse effect.
 
Many people who have had allergic reactions to seafood or x-ray solutions may have been told that it is the iodine component that they are allergic to, which is not very probable. The radiology solutions and foods that contain iodine have many other components (or allergens) that are more likely to cause these types of reactions. If dietary iodine were truly the cause, one could not eat any foods containing iodine. Since so many foods contain small amounts of iodine it would be very difficult to avoid it completely. Of course, if you did avoid iodine completely, you would be faced with the deficiency problems discussed previously.
 
Some of the foods commonly containing dietary iodine and their iodine content per serving are as follows: dried beans -115 mcg, seafood - 66 mcg, spinach - 56 mcg, vegetables - 30 mcg, milk - 14 mcg, eggs - 13 mcg, whole grain wheat - 9 mcg, smaller amounts are founds in other grains, beef, rice, and even fruits.
 
If you have been told to avoid supplemental iodine because of a medication you are taking or because of a thyroid condition, please discuss the use of the Chelated Minerals with your health care provider.
 
A daily dose of the U.S. Chelated Mineral product provides 225 mcg of iodine.
