Meet Our Chief Medical Advisor
Dr. Warren Ringold, M.D.

Hi, my name is Dr. Warren Ringold. 

I am a licensed U.S. medical doctor that graduated from the University of Michigan Medical School in 1976. During my career I have been featured on TV programs like CBS’ 60 Minutes and also featured in newspapers and magazines like People Magazine.

Throughout the years, I built a large, successful medical clinic with thousands of patients and since have retired.

Additionally, I’ve been the Chief Medical Advisor to Ringold Nutritional Systems for over 15 years, and along with a leading team of scientists we are dedicated to formulating the highest quality dietary supplements with unparalleled ingredients helping tens of thousands of people around the world.

My wife of more than 50 years and I have 6 grown children and 13 grandchildren. My personal eyesight became a grave concern to me when I was told by my eye doctor that I had the early stages of a debilitating eye condition affecting my macula.  I was told it could lead to severe vision loss, and the only protection was taking specific combinations of vitamins and minerals. 

This led me on a journey almost two decades ago to carefully formulate the company's flagship product, Preserve Mac Forte, which is still one of the most complete vision supplements on the market to this day.  Since then millions of capsules have shipped to customers around the world. 

Still now, each of the company's nutritional products is prudently crafted with only the finest ingredients. Every ingredient that enters our facility is highly scrutinized for quality at each step of the manufacturing process. All of our products must pass a stringent 3-step purification process before approving them as "Triple Test Certified." 

These are the products that I use and trust. I would recommend these products to my wife, mother and anyone else who wants premium nutritional supplements with science-backed ingredients.

Safe, Proven Ingredients

Let's face it - a dietary supplement is as only good as what each capsule has inside. Some store bought products are produced in China or third world countries and may not contain what is stated on the label, or worse yet they may contain contaminants, fillers, and cheap ingredients.

Our products are different. 

Our products are made in the USA in an FDA compliant facility. Plus, every bottle is "Triple Test Certified" and must pass a stringent 3-step purification process that guarantees the highest quality product and only the purest ingredients in every bottle.  

This rigorous 3-step process is supervised by a staff of Ph.D.s. constantly monitoring for quality.  From raw materials entering the manufacturing facility through testing dosage potency and capsule disintegration, we ensure product quality and consistency in every bottle of our products.

It Works!

"I started taking Preserve Mac Forte Advanced 3 years ago. After 6 months I noticed that my glasses were really bothering me. So I went to my eye doctor and he told me my eyes were better. My glasses went down one step. I continued taking it and after a year I regressed back 2 pairs of glasses. I went back to my doctor and he said he could not believe what had happened. I would like for other people to know that Preserve Mac Forte Advanced works. If anyone is skeptical about trying Preserve Mac Forte Advanced I would say don't hesitate and take it immediately."

Been taking it since 2008!

"I heard about this product from a friend.  I decided to try it because my friend had good results.  I starting using Preserve Mac Forte Advanced in November of 2008 and what I like most is that it seems to be helping my condition. I would tell people who are thinking about trying Preserve Mac Forte Advanced that originally I was somewhat skeptical, but would recommend to try it for 6 to 8 months and see if it helps you."
