    About Us

Supplements from Science

At Theralogix, our methodology is simple: We only create products that are backed by published scientific evidence. To ensure that we stay true to this unwavering commitment, we prioritize research that demonstrates our products will address a specific need.

As science evolves, so do we, continuing to develop new products and improve current ones.​

Exceptional Ingredients, Without Exception

We never compromise on quality. We source only the finest ingredients to maximize performance and bioavailability and we prioritize the specific nutrient forms used in published clinical research.​

Certified Pure

Not all supplements are created equal. Our products are certified for content accuracy and purity by NSF® International – one of the most rigorous third-party dietary supplement testing programs in the world. This certification guarantees that our supplements contain exactly what they should, and nothing they shouldn’t.

And it’s never one and done. Our supplements continually undergo re-testing so you can trust every single product, every single time.  

We Don't Round Up. We Pass Savings Down.

You might notice our prices are oddly specific — and that’s on purpose.
We don’t believe in rounding up just to make things look cleaner on the surface. Instead, we pass every possible saving directly on to you. No hidden agenda. Just honest pricing that further reflects our commitment to transparency — down to the last cent.

Referred & Preferred for Decades

Thousands of physicians and other healthcare providers around the country have recommended us to their patients since 2002.

Over a million referrals and counting.

Our supplements are the top choice for providers and patients who rely on superior quality. ​

Clinical Trials

Another reason to feel good about choosing Theralogix: Top universities do, too. Research institutions, including the National Institutes of Health, Harvard University, and Cornell-Weill Medical College, have chosen to use Theralogix products in ongoing clinical trials. They trust our supplements for their high-quality and content-accurate formulations.

We’re honored that our work helps further the field of nutritional science.​

A Physician on a Mission

At the heart of the Theralogix brand is physician and Chief Science Officer, Dr. Mark Ratner. In 2002, he founded the company to create nutritional supplements that healthcare providers could believe in – and patients could benefit from.

Guided by physicians and scientists at the nation’s leading hospitals and academic medical centers, the Theralogix product family launched with a single men’s health supplement.

Our product line has now grown to 30+ supplements spanning multiple specialties – fertility, rheumatology, urology, women’s health, and more.​

Medical Advisory Board

No supplement brand goes further than Theralogix to ensure scientifically-sound products. For proof, look no further than our Medical Advisory Board (MAB).

Made up of a carefully selected group of physicians, top research scientists, and faculty members at leading U.S. medical schools, our MAB evaluates and approves new product formulations, while offering guidance to improve existing ones. ​
