Nature Works Best is a natural integrative cancer clinic located in Tempe, Arizona, that focuses on natural, holistic, integrative and alternative cancer treatments. The clinic offers metabolic treatments via their team of naturopathic medical doctors, who have administered over 52,000 IV nutrient treatments, used for all stages and types of tumours.

Nature Works Best was founded by Dr Colleen Huber in 2006. She is currently on sabbatical from practicing medicine, while writing books and articles, and staying involved with the clinic. Dr Huber has served as President of the Naturopathic Cancer Society and co-founded the American Naturopathic Research Institute / Naturopathic Oncology Research Institute. Dr Huber was the principal keynote speaker at the 2015 Euro Cancer Summit, and in 2014 was a speaker at the World Congress on Cancer Science and Therapy, and at the International Congress of Naturopathic Medicine.

She wrote the books Choose Your Foods Like Your Life Depends On Them, Manifesto for a Cancer Patient, among other books and articles. Dr Huber authored the largest and longest study in medical history on sugar intake in cancer patients, which was reported in thousands of media outlets around the world in 2014. Her academic writing has appeared in The Lancet and Cancer Strategies Journal, and other medical journals.

Unlike most clinics, Nature Works Best publish all of their results, both successes and failures, and including every patient who takes the metabolic treatments for at least two weeks. The clinic does not turn away patients due to being “too sick” and will “ruin their statistics.”
