A Legacy Rooted in Science and Healing

• For over 40 years, our family — now three generations of chiropractors — has been dedicated to researching, developing, and providing therapeutic magnetic products. Our story began in the late 1960s with the pioneering work of Dr. Ralph U. Sierra, the first chiropractic doctor in Puerto Rico and a visionary in biomagnetism.

Thousands of clients and patients have experienced relief and wellness through the correct use of magnetic therapy, thanks to the dedication of our family:

• Dr. Ralph U. Sierra
• Dr. Irma I. Sierra
• Dr. Jorge C. Jarrot
• Dr. Jorge R., Dr. Adrian & Dr. Alexandra Jarrot Sierra
  

We now stand on the verge of a great new age in magnetic science and its applications, a tool that has been provided by Mother Nature itself. Quote of  one of the voices of the experts “Dr. Ralph U. Sierra.”  

Our Story

It all began in 1967. Dr. Ralph U. Sierra, then 63, was suffering from Meniere’s disease and an enlarged prostate. He began research with Albert Roy Davis, applying a simple domino magnet to his ear and drinking north-charged magnetized water. This experience sparked a lifelong commitment to magnetic healing.

Dr. Sierra founded the Puerto Rico Scientific Research Laboratory, which became a global hub for collaboration with scientists, doctors, and researchers from the U.S., Canada, Japan, China, Australia, and more. Together, they explored the physiological effects of magnetic fields on living systems.

Throughout the 1970s and early '80s, Dr. Sierra became an international speaker, featured on TV and radio shows and in publications across the Americas and beyond. He co-authored several books, including Power in a Magnet and Energía Magnética, and was referenced in works like The Body Electric and Magnet Therapy by Dr. Buryl Payne.

One of his most iconic innovations, “The Magic Bands of Dr. Sierra,” was adopted by athletes worldwide. These flexible magnetic supports were handcrafted for injured joints — and were the inspiration for many of today’s commercial magnetic wraps.

Sadly, Dr. Sierra passed in 1982 following a fall. Yet, his legacy lives on through the continued work of his family and the mango tree he magnetized, which still bears sweet fruit to this day.

Carrying the Torch

In 1984, Dr. Irma I. Sierra, daughter of Dr. Sierra, began her chiropractic practice using her father’s original equipment. She was joined by her husband, Dr. Jorge C. Jarrot, who shared a deep interest in biomagnetism and later became a chiropractor himself.

Together, they expanded the family mission, and today, their three children — also chiropractors — continue to uphold the Sierra-Jarrot tradition of excellence in biomagnetism and natural wellness.

We have witnessed firsthand how manufacturing of magnetic products exploded globally in the 1980s. However, not all products are created equal. Many mass-produced magnetic items lack therapeutic potency, polarity accuracy, or even real magnetic charge.

At Health Magnetic Store & More, we:
- Evaluate each product for correct polarity (north-facing when applicable)
- Verify magnetic strength and field penetration
- Ensure design integrity for actual physiological effect

We educate our customers so they can avoid ineffective or misleading products and invest in tools that truly support their health.
