Lead Contamination in Calcium Dietary supplements 

Calcium pills

Do calcium citrate and calcium carbonate have as a lot lead as calcium dietary supplements derived from dolomite and animal bone? 

You might keep in mind I’ve explored the position calcium dietary supplements might play in lowering lead publicity throughout being pregnant and breastfeeding, however that assumes the dietary supplements themselves are nocontaminatedDietary supplements with lead? 

It began with a unprecedented case report revealed in 1977, entitled Lead-Contaminated Well being Meals. As focus on in my video Lead in Calcium Dietary supplementsa physician prescribed a dietary complement for a younger girl with painful intervals. Not simply any younger girl, although. She was tv and film star Allison Hayes, well-known for her roles in movies akin to Assault of the 50 Foot Girl. And, not simply any doctor, however Dr. Henry Bieler, doctor to the celebrities, who informed his sufferers to overlook about poisonous medicine; meals is your greatest medication,” as you possibly can see in an commercial proven at 0:44 in my video. In this case, it was a calcium complement made from horse bone. She took it every single day, however bought weaker and sicker, and by 1967, her performing profession ended when she grew to become unable to stroll with no cane. Ms. Hayes noticed physician after physician after physician, 22 in all, to no avail. She reported she concluded she had three choices: “(1) commit suicide, (2) go to a psychiatrist to try to be taught to reside with the ache…; or (3) discover the reply myself.” 

She had some associates drive her to a medical library. By then, she couldn’t even stroll and needed to be carried in. She sat on the ground contained in the library, day after day, and at last got here throughout a e-book on industrial toxicology that described what she quickly realized was a basic case of lead poisoning. She paid to have the calcium complement examined, and, certainly, it was filled with lead. At first, she was relieved. “Then the anger set in.” Doctor after physician had primarily dismissed her as hysterical, and, finally, she needed to rely on herself to educate them. 

The silver lining was that, in a letter, the U.S. Food and Drug Administration really credited “the intrepid actress for being a key stimulus’” for the company’s plans to begin wanting into regulating heavy metals in meals and dietary supplements. Sadly, the letter arrived after Ms. Hayes had already died from leukemia, which can have been triggered by the lead poisoning or the 300 x-ray exams she bought from these 22 baffled physicians. 

Wouldn’t you assume the complement business would clear up its personal act? “It is unrealistic to anticipate the well being meals business and wellness’ press to dampen their evangelistic promotion of those merchandise on a unilateral foundation,” that’s, on their very own.  

The place did the lead in her dietary supplements even come from? Keep in mind, she had been taking a calcium complement constructed from horse bone. Lead will get saved in your bonesso once you take dietary supplements made out of bones, you will get uncovered. In that casewas that one calcium complement simply the tip of an iceberg? At first, we thought it was simply from the bone dietary supplements and dolomite, a mineral that may be contaminated with lead, but then calcium carbonate—oyster shell calcium, chelated calciumwas discovered to have comparable lead ranges to animal bone, as you possibly can see at 2:56 in my videoThis impressed a complete survey of the lead content material of 70 totally different manufacturers of calcium dietary supplements. As you possibly can see at 3:09 in my video, lead ranges diversified by nearly 300-fold, with some twothree, and even 4 occasions the tolerable every day consumption of lead for youngsters. Greater than half of the most typical, pure supply calcium dietary supplements, like these containing oyster shell, had lead ingestion charges exceeding the benchmark for youngsters. 

A follow-up examine confirmed that the majority calcium dietary supplements from pure sources exceeded a minimum of a number of the most stringent lead requirements, however the ranges solely bought as much as about 8 micrograms, whereas a number of the artificial sources had been as much as thrice that, as you possibly can see at 3:27 in my video. 

A small human examine of calcium citrate was carried out through which bone biopsies had been taken earlier than and after about 5 years of supplementation. As you possibly can see at 3:49 in my video, there was no change in the management group, as anticipated, and solely a statistically insignificant improve within the calcium citrate group. Nonethelessone cannoassume {that a} given model is uniformly protected, as a result of a few of their merchandise might have excessive and others low lead ranges.” What does this imply? “Sufferers and customers ought not assume protected lead ranges from preparations which have model titles or are provided by acknowledged pharmaceutical corporations”—that’s, there’s no assure, even when we’re conversant in the producer 

There may be some excellent news, although. After a long time of concern, lead ranges in calcium dietary supplements have come down. The truth isthey’ve come down a lot that modifications in lead ranges in your blood, taking the typical lead-contaminated calcium complement, can be minimal at this level. So, these findings on lead contamination of dietary supplements ought to be a trigger for celebration, not alarma minimum of based on a marketing consultant to a calcium complement producer. 

What a tremendous—and amazingly unhappy—story.
