Jim English
Jim English is a widely published nutritional-science editor and author of several books and articles on nutritional supplements. 
In 1991 Jim founded Smart Products, a unique company that introduced America to a number of novel supplements — many previously unavailable at the time — such as DHEA, melatonin and pregnenolone. In 1992, Jim was interviewed on the benefits of Ginkgo Biloba and other cognitive-enhancing supplements by Barbara Walters.
In 1993 Jim launched his first newsletter, IntelliScope. Dedicated to consumer education, IntelliScope avoided hype and published fully-referenced articles, product reviews, and ground-breaking interviews with leading antiaging researchers, such as Durk Pearson, Sandy Shaw, and Ward Dean, MD.
Jim has also served as editor of Focus on Health (Allergy Research Group/NutriCology), senior editor and writer for Vitamin Research News, and contributing writer for Life Extension Magazine. Recent publications include A Users Guide to Ginkgo Biloba, A Users Guide to Vitamin C, and several anthologies of collected articles (2000 and 2001), co-authored with Ward Dean, MD.
In addition to running Tango Advanced Nutrition, Jim also hosts Nutrition Review, a free online resource on the therapeutic application of nutritional supplements for preventing disease, enhancing health and extending life.
John Steinke
John began his medical career as an acupuncturist and herbalist specializing in sports medicine, including trauma care and performance enhancement. 
He noted that the elite athletes he treated for their injuries all showed signs of premature aging.
Football players and other contact sports athletes suffer from chronic pain disorders from frequent injury. Distance runners and triathletes develop chronic fatigue and immune disorders from overtraining. John then developed programs using the antiaging essence herb formulas from China to help both groups of athletes with a great deal of success.
His work is highlighted in Total Impact, the autobiographical story of San Francisco 49er Ronnie Lott’s playing career.
Since everybody eventually suffers from premature aging related to poor blood circulation and weak energy metabolism, John decided to offer his sports programs to the general public. He initiated contacts with leading Chinese research institutes to bring their modern formulas for aging disorders to the US.
