“Evidence of toxicity from purple corn extract was not found,” says a report submitted by the Rainforest Botanicals LCC (a natural food supplement company) to the Office of Nutritional Products, Labeling, and Dietary Supplements of the Food and Drug Administration or FDA in February 2005. Furthermore, the study concluded that based on the proofs derived from the animal tests for pesticides, heavy metal, and caffeine levels done on purple corn, it may be safe to assume that purple corn (particularly that variety from Rainforest Botancals) is safe.
As far as toxicity is concerned, the study showed that no proof of animal or human toxic, cytotoxic, or mutagenic effect to healthy cells was evident. With tests on heavy metals, pesticides, and caffeine levels, purple corn has also been found to be safe. Mercury, lead, arsenic, and cadmium were not traced in “detectable amounts” as well as pesticides. caffeine contents were found to be negligible.
The high anthocyanin content in purple corn was also found to be safe, and the study cited published reports on how the corn “failed to cause hepatotoxic or nephrotoxic effects” in rodents that severely lacked glutathione even after an acute dose of 4500 mg/kg.
Purple corn is safe, and it follows that any supplement derived from pure Peruvian purple corn, provided it has no additives or preservatives harmful to health, is also safe. Taken regularly with the right dosage will give you safe health benefits from its various properties–anti-hypertension, anti-heart diseases, anti-cancer, anti-inflammation, anti-aging, anti-obesity, and anti-diabetes, to name a few.
There is no need to fear any side effects from taking pure purple corn supplements because purple corn has been proven safe and beneficial and passed FDA standards. Thus, when buying purple corn products, make sure to get nothing less than those with approved and high quality. Look at the label to see if any harmful additives or preservatives have been added.
The best kinds of purple corn crops are often those that are harvested from organic farms like those coming from Peru itself. These farms are rendered free from any chemical application on both the soil and the plants and crops. Moreover, this also means adjacent farms are also chemical free.
