Calcium Aspartate (EZorb) Review
Calcium aspartate anhydrous is sold under the brand name EZorb(r) as a stable, organic calcium with an extraordinarily high rate of absorption. While intriguing, the EZorb manufacturer cites only unpublished research to support its claims. The claims and technology for calcium aspartate closely resembles those coral calcium supplements, the same products that were slammed by the Federal Trade Commission (FTC) and federal courts for false advertising claims.
Similarities to Coral Calcium Claims
According to the Ezorb Company’s website (http://www.elixirindustry.com/ezorb/index.html):
“The exceptional longevity of the people of Okinawa has baffled scientists for ages. Some have speculated that the secret of the islanders' long life must be in the water they drink. But what exactly is in the water of Okinawa that promotes health and long life?
[T]he team [of scientists] identified key substances linked to the long lifespan enjoyed by the Okinawans: organic calcium compounds, which developed naturally over the course of millennia.
The product, named "EZorb" because of its superior calcium absorption rate, clearly outperforms any other calcium supplement, delivering convincing results.. No prescription medications or other calcium supplements even come close to EZorb in terms of improving the health of bones, joints, and muscles.”
That Okinawan longevity story may sound familiar. It was the same angle used to promote coral calcium supplements on TV infomercials.
The Ezorb website goes on to note that its calcium aspartate anhydrous has “92%” absorption rate and can increase bone density. The absorption rate is calculated strictly based on rat studies. Humans can not absorb large amounts of calcium at once. According the National Institute of Health (NIH) in its calcium Fact Sheet:“The percentage of calcium absorbed depends on the total amount of elemental calcium consumed at one time; as the amount increases, the percentage absorption decreases. Absorption is highest in doses ≤500 mg.”
The bone density report provided on calcium aspartate raises several questions. Also, the report, itself, appears to be unpublished and therefore not subject to the standard medical peer-review process. Additonally, it fails to note where the research was done or the accreditations of the study authors.
An independent panel evaluating Ezorb advertising found that the company’s claims were not substantiated.
“Direct response advertising for the EZorb Calcium Supplement, manufactured by Elixir Industry, came to the attention of the Electronic Retailing Self-Regulation Program (“ERSP”) pursuant to its ongoing monitoring program.
ERSP determined that the evidence in the case record does not support comparative claims made in the EZorb Calcium Supplement advertising. Moreover, although the testing does illustrate some general performance improvements in calcium deficient disorders, the lack of specific testing on the product as packaged does not support all of the specific performance claims.”
Calcium aspartate anhydrous, like EZorb, is probably a good form of calcium. It likely benefits bone health. However, it lacks the scientifically objective evidence suggesting that it can increase bone density or be well absorbed in humans, comparably to a clinically effective calcium such as AdvaCAL. Until that type of scrutinized data is published, consumers can only hope for the best when taking calcium aspartate.
