Gary Null ("Ph.D."), is an alleged researcher, nutritionist, herbalist, political activist and proud bearer of a great haircut. In his practice as a nutritionist he believes, among other things, that nutrition contributes significantly to overall health and well-being. This is simple common sense, but Null's practices and his brand of supplements are a step beyond this.
He believes that most of the ideas commonly held by Western medicine, such as treating illness with medication, are contrary to good health and that Western medicine attempts to treat symptoms, not the actual cause of the condition. He promotes and markets a variety of foods, herbs, supplements, fad diets and various other forms of woo that he claims to be able to cure and prevent many illnesses. His methods and suggestions are labelled "dubious at best" by most of the leading authorities and research bodies into arthritis, heart disease and cancer.
He is the author of many, many, many books, with titles such as 7 Steps to Overcoming African-American Health Problems, 7 Steps to Overcoming Arthritis and Back Pain (because thumbing through a fiddly book is going to be easy with chronic arthritis) and AIDS: A Second Opinion (which seems to attempt to refute pretty much everything known about AIDS).
Null claims a PhD in "Interdisciplinary Studies" (thesis title: "A Study of Psychological and Physiological Effects of Caffeine on Human Health") from Union Institute & University, a correspondence college. Union Institute & University is accredited by the Higher Learning Commission, but only offers doctorate degrees specializing in education, leadership, humanities, and public policy.

Gary Null has been active on radio and television for some time. He has appeared on PBS and Pacifica Radio outlets, especially during fundraisers. He founded the Progressive Radio Network webcast in 2006 to, in part, peddle woo. On 16 October 2009 "Dr" Null organised a rally against vaccination in New Jersey in response to it mandating the flu vaccine.
In an unsurprising example of crank magnetism, Null appeared in Psychiatry: An Industry of Death, a "documentary" produced by the Citizens Commission on Human Rights, a front group of the Church of Scientology. 
I liked it so much, it nearly killed me
Null (as well as six other consumers) nearly died from overdosing on Vitamin D from eating his own branded "Ultimate Power Meal" twice a day. He claims that the supplement contained much more vitamin D than reported on the label, which is a plausible explanation. He is suing the company that makes it for him.
