First, do no harm
With any product a fundamental issue is safety. The safety of esterified oils was tested at the University of Minnesota. Researchers gave these oils to animals in enormous quantities—1,300 times the regular dose or the equivalent of a human consuming 3,900 capsules daily (3 per day x 1,300). Even at these very large dosages, no pathology or concerns were detectable.
