THE APPROACH
Understanding what we put into our bodies is fundamental to understanding our health.
Dr. Riker's approach to nutrition begins with examining the evidence, understanding how dietary and lifestyle choices affect the body, and using that knowledge to make more informed decisions about long-term health.
THE FORMULATIONS
Developed around specific areas of health.
Each proprietary formulation brings together nutritional compounds and botanical ingredients selected for their documented functions in humans and the complementary roles they may provide within the body.

Who is Dr. Adam Riker?
Dr. Adam I. Riker, MD, FACS, FSSO, is a board-certified surgeon and practicing surgical oncologist with more than 25 years of clinical experience. His work spans clinical medicine, cancer research, human nutrition and lifestyle medicine. He is also the author of two books exploring nutrition, lifestyle and long-term health and the physician behind The Riker Regimen.
What is Dr. Riker's approach to nutritional supplementation?
Dr. Riker's approach begins with nutrition, physical activity and sustainable lifestyle choices. Supplementation is intended to complement that foundation, not replace it. His approach examines published evidence, the biological functions of nutritional compounds in humans and how ingredients may work together to support specific areas of health.
How do I choose the right formula?
Start with the area of health you want to support. The Riker Regimen formulations are organized around inflammation, sleep, cognitive function, immunity, metabolism, longevity, and anxiety and stress. Visit Shop by Concern to explore the formulations associated with each area and learn more about their ingredients and intended nutritional support.
Can The Riker Regimen supplements be taken together?
Some Riker Regimen formulations are specifically recommended together. For example, Dr. Riker's existing guidance pairs NMN with LONGEVINATOR and discusses using ORGANO-CALM with REM-STATE as part of an evening routine. Because individual needs, medications and health considerations vary, review the Suggested Use for each formula and consult your physician or qualified healthcare professional before combining supplements.
Where can I learn more about the ingredients in each formula?
Each supplement page includes information about key ingredients, their documented functions and the rationale behind the formulation. For broader education on nutrition, ingredients and health, visit the Health Library, where Dr. Riker explores these subjects in greater depth.
Can I take The Riker Regimen supplements with medications?
Dietary supplements can interact with prescription and over-the-counter medications, and individual circumstances vary. If you take medication or are under medical care, consult your physician, pharmacist or other qualified healthcare professional before beginning a new supplement or changing your current regimen.
How should I take my Riker Regimen supplements?
Suggested use varies by formulation. Refer to the Suggested Use section on each product page and the directions provided on the product label for serving size and timing. If you have questions about how a supplement fits into your individual routine, consult your physician or qualified healthcare professional.
