The Foundation for Health & Vitality: Natural Supplements by Dr. Jerry Tennant

Choosing natural supplements shouldn’t feel overwhelming or uncertain. Too many brands rely on flashy labels, vague science, and empty promises.

Tennant Products takes a different approach to natural health .

We build every formula on clinical insight, rigorous research, and uncompromising quality. We design each supplement to support cellular health using bioavailable, methylated supplements that your body can actually use.

Dr. Jerry Tennant, founded Tennant Products to simplify the journey toward better health based on his own experiences.

We are rooted in real science, heartfelt integrity, and a genuine desire to help. Whether you’re just beginning to explore natural health or are seeking something more effective and intentional, this is where your wellness journey can find solid ground.

Who We Are: Champions of True Wellness

At Tennant Products, our mission is simple. We aim to bring you the highest-quality natural health products crafted with integrity. Named after its founder, Dr. Jerry Tennant, a Harvard-trained ophthalmologist turned integrative health pioneer.

His life and work changed dramatically after he faced a devastating prognosis. Doctors told him he had six months to a year to live. Instead of accepting that outcome, Dr. Tennant committed himself to understanding how the body truly heals.

Our mission is to deliver the highest-quality, all-natural supplements that are bioactive and readily absorbable. We believe your health deserves nothing less.

Our vision is to empower individuals and healthcare professionals to live their best lives through better nutrition. Tennant Products is committed to delivering the nutrients your body needs to build healthy new cells and support natural healing and energy.

Why You Can Trust Tennant Health Supplements

What earns trust in the world of Tennant supplements is not a flashy label. It is our uncompromising standards and commitment to excellence.

Purity You Can Trace
All products are proudly 100 percent made in the USA, with no GMOs, artificial fillers, unnecessary excipients, or unnecessary sugars. Ingredients are meticulously traced back to their source, sometimes as far as Siberia or Japan, always in pursuit of the purest form available.
Bioavailable and Methylated for Efficiency
While many brands overlook how much of a nutrient can be lost during digestion, we take this seriously. That’s why we prioritize using bioavailable & methylated ingredients. For instance, instead of niacin, we use NADH, allowing your body to absorb and utilize it immediately without the extra conversion steps.
Backed by Research and Updated with Care
We continuously review the latest science. When new research revealed that delta-tocotrienols offer better absorption than mixed tocopherols, we made the switch. This decision increased cost but delivered superior results.
Formulas That Perform
We prioritize effectiveness in every formula of bioavailable supplements we create. Take our Brain Food Plus, for example. It delivers sustained energy and focus without relying on stimulants. Instead, it's powered by MCTs and ketones to support mental clarity and performance without the crashes or jitters. Our Probiotic Formula is another example, featuring Capsugel® DRcaps® (Delayed-Release Capsules), a specialized delivery technology designed to protect probiotics from stomach acid and ensure they reach the intestines intact. This allows them to effectively colonize the gut and support overall health and wellness. We also include prebiotics to nourish the probiotics, helping them thrive where they’re needed most.
