Supplements are a multi-billion-dollar industry that centers around sometimes over-hyped marketing claims. In the case of Cardio Renew and Angioprim, the makers claim that the products clean out your arteries, resulting in increased energy and well-being. Because these are supplements and not drugs, they are not regulated or standardized in any way, so the label may not exactly match what's in the bottle. Moreover, both companies have been warned by the FDA to stop making false claims about their products.

Angioprim is billed as the "original liquid oral chelation," and the official website claims the formula will bind to arterial buildup and draw it out. According to the manufacturer, this will reduce your risk of heart attack. The formula also contains the amino acids caysine, lysine and cysteine. Caysine is the company's own proprietary blend, and the website does not mention the ingredients other than to say it is a food preservative. Neither lysine nor cyteine has been proven to improve cardiovascular health, notes the United States National Library of Medicine.
Cardio Renew is also a form of oral liquid chelation therapy, but it uses a compound called EDTA instead. Although EDTA has been used successfully to treat heavy metal poisoning by clearing it from the blood, the American Heart Association states that there is not enough evidence to suggest its effectiveness in treating arterial buildup when used intravenously, let alone orally. Cardio Renew's cleansing formula contains only EDTA, although the manufacturer also recommends several vitamin formulas as accompaniments to the therapy.
Angioprim and Cardio Renew are bitter rivals, each devoting space on their website to bashing the other product. This originated from a business dispute, but the facts are unclear. Angioprim claims that a former salesman used what he mistakenly thought was the Angioprim formula to make Cardio Renew. According to Cardio Renew, their founder was a former Angioprim partner who left the company due to differences with the other partners. Cardio Renew claims that their product is not a knock-off of Angioprim because it contains entirely different ingredients.
Both companies have been warned by the FDA for making claims that their supplement will cure, treat or prevent disease. If that is in fact the case, the supplement would be classified as a drug and would have to undergo a rigid and lengthy regulation process. Angioprim was warned in 2005, with the warning mentioning 14 improper claims, and Cardio Renew was warned in 2010 about 60 improper instances. Both warning letters mentioned that the list of non-compliance instances was not complete because there were too many to include in the letter. Both companies were ordered to stop promoting their formula like a medication.
Both product websites mention that the supplements should not be taken by anyone under 18, or people with liver or kidney disease. The warning letters from the FDA say that the ingredients are not recognized as safe or effective, so use them at your own risk. If you decide to begin taking either Angioprim or Cardio Renew, consult your doctor first. These supplements may react with other medications and produce adverse effects, or they may aggravate other health conditions you may have.
