Clinical Claims and Research
The Krebses' original patent claimed pangamic acid could be used for detoxification as well as treatment of asthma, skin conditions, joint pain, and nerve pain, with none of these claims supported by evidence in the patent application. Early promotion for pangamic acid included use by race horses as well as humans. Although given the name "Vitamin B15" by the Krebses, there is no evidence that it meets the definition of a vitamin as there is no evidence it is a nutrient needed by the body.
Much of the clinical research on pangamic acid took place in the former Soviet Union, though that research often did not describe which of the many compounds called "pangamic acid" was used in the study. This research was also of limited quality due to being overwhelmingly anecdotal in nature (as opposed to controlled experimentation) and ignoring short and long term safety in human use.
Although more recent claims include treatment of a wide variety of conditions including cancer, heart disease, schizophrenia as well as providing improvement in oxygen utilization, there is no significant evidence for any of these claims or that it is safe for human use. One review noted that it meets "the criteria that define a quack remedy."

Famous quotes containing the words claims and/or research:
“Let me live onward; you shall find that, though slower, the progress of my character will liquidate all these debts without injustice to higher claims. If a man should dedicate himself to the payment of notes, would not this be an injustice? Does he owe no debt but money? And are all claims on him to be postponed to a landlord’s or a banker’s?”
—Ralph Waldo Emerson (1803–1882)
“The working woman may be quick to see any problems with children as her fault because she isn’t as available to them. However, the fact that she is employed is rarely central to the conflict. And overall, studies show, being employed doesn’t have negative effects on children; carefully done research consistently makes this clear.”
—Grace Baruch (20th century)
