Question 1

Why does this contain lead ??? That’s horrible !!! We don’t need anymore toxins !!

Accepted Answer

In 1986, the State of California adopted the Safe Drinking Water and Toxic Enforcement Act (Proposition 65), which applies not only to water quality, but also to consumer goods sold to the California public. Prop 65, as it is known, requires the State of California to publish and maintain a list of chemicals, known to the State of California to cause cancer, birth defects, or other reproductive harm.  A few of Allergy Research's formulas contain ingredients that have small amounts of naturally occurring lead, and the total amount of lead in a full daily serving (the high end dose in the “Suggested Use” portion of the label), even though low, is higher than that allowed by California Proposition 65. The warning is only required for product sold in the State of California.

Allergy Research Group has always tested its products for the presence of heavy metals, including lead, arsenic, mercury, and cadmium. The United States Pharmacopeia mandates no more than 10 μg/lead per day from any product, and all of their products are far below that level. California Proposition 65, however, sets the lead standard 20 times lower, at 0.5 μg/day. Because Allergy Research has always endeavored to obtain the purest natural ingredients, the vast majority of their products exceed this standard as well.

None of Allergy Research's products contain a high amount of lead. Even for the few formulas that carry the CA Proposition 65 warning, a full daily serving contains a small percentage of the typical daily intake of lead from food (Kehoe; EFSA Journal). In fact, a serving will contain significantly less lead than a serving of many food items in North America (Schroeder and Balassa; FDA Total Diet Study).

Rest assured that Allergy Research will meet the challenge of finding even purer ingredients so that none of them add any significant amount of this ubiquitous mineral to that already present in food and water.

Question 2

Why is povidone in the ingredients?

Accepted Answer

Povidone formulations are widely used in the pharmaceutical industry. Povidone has also been used as blood volume expander and lubricant in eye drops, as well as in coatings on fresh citrus fruits; as a clarifying agent for beer, wine and also vinegar. It absorbs bad bacteria and helps to get rid of Endotoxins.
