Tennant Products is a company that puts quality first. Created by renowned health researcher Dr. Tennant, the company offers a wide range of supplements and products that are designed to support your health and well-being. With a focus on natural ingredients and effective formulas that are sourced from the best corners of the world and manufactured in the USA, Tennant Products aims to provide high-quality products that are both safe and effective.
When it comes to supporting the body, purity and quality matter. That's why Dr. Tennant's® supplements are made without GMOs, fillers, added sugars, artificial flavors, or harmful excipients. Unlike many brain supplements that rely on stimulants like caffeine, Dr. Tennant's® Brain Food is designed to fuel the brain naturally. By using MCTs, ketones, and bioavailable cofactors, it provides long-lasting focus and mental clarity—without the jittery side effects or crashes of caffeine-based products.
Every supplement in the Dr. Tennant's® line is manufactured in the USA under strict GMP (Good Manufacturing Practice) standards. What sets these products apart is the rigorous sourcing process—each ingredient is traced back to its origin to ensure purity, with no unwanted toxins or additives introduced along the way.
Many people struggle to fully absorb nutrients due to inefficient methylation, a process that converts vitamins and minerals into usable forms. Over 40% of the population has difficulty with this, which is why Dr. Tennant's® supplements use only bioavailable, methylated ingredients. This ensures the body can absorb and utilize the nutrients effectively—without needing extra conversion steps.
Dr. Jerry Tennant, MD, MD(H), PScD, is a world-renowned physician, integrative health practitioner, and author, recognized among the Top 20 Alternative Doctors in America. A Harvard-trained ophthalmologist and pioneer in LASIK surgery, Dr. Tennant revolutionized eye care with numerous medical device patents before his career took a dramatic turn. After contracting severe brain viruses from surgical exposure, he faced years of debilitating illness, unable to find answers within conventional medicine. Determined to heal himself, he delved into cellular biology and discovered that optimal health depends on maintaining proper cellular voltage. This realization led him to develop groundbreaking theories on chronic disease and regeneration, proving that restoring cellular voltage can reverse illness. Through his research, he regained his health and now shares his knowledge worldwide, helping thousands recover naturally. Dr. Tennant's books, including Healing is Voltage, detail his discoveries and have made a profound impact in holistic health.
