Product Information


Oxy-Energizer was one of the first products developed by Andrew Lessman in 1979 based upon extensive research in France, Germany and Japan. Its original formula was the subject of a US Patent and has gone on to become one of our most popular products ever since. It is a unique combination of two vital electrolyte-minerals (Potassium and Magnesium) fully reacted with Aspartic Acid and Citric Acid to form a stable complex that is chemically referred to as Potassium-Magnesium Aspartate-Citrate. Please note that despite the similar name (aspartate), it is a natural amino acid and NOT the unrelated, undesirable food additive Aspartame. Potassium and Magnesium are often overlooked by most individuals, but their dramatic impact on general and hear t health should never be neglected. Oxy-Energizer was originally developed for health care professionals to support the energy and performance requirements of their elite athlete patients, and it is now most frequently used by individuals like you to support optimum cellular energy production. Oxy-Energizer's mechanism of action stems from its “mineral-transporter” properties, which allows it to help support the energy requirements necessary to maintain healthy, high concentrations of Potassium and Magnesium inside all your cells. This process of balancing electrolytes for all of the trillions of cells in your body, particularly the cells of the heart muscle, requires extreme amounts of energy. The unique, natural mineral-transporter properties of Oxy-Energizer supports your cells, particularly those of the heart, in more efficiently performing this vital energy-demanding function thereby conserving energy for other essential functions.

The best of the best I have tried many similar products so far. None of them are so efficient like Andrew's the Original Oxy-Energizer. I strongly recommended.

Fewer leg cramps at night! We have both been taking this for several months now to help reduce getting leg cramps during the night. Andrew doesn't advertise it for that, but It has definitely been making a difference. A significant body of research has found that increasing your magnesium intake can help with the frequency of night time leg cramps, especially for pregnant women. Thank you Andrew for another great product!

Oxy-Energizer I easily develop kidney stones and had low Potassium and Magnesium so my doctor prescribed Potassium Citrate. I had to take (3) daily as well as take them for the rest of my life. The meds are extremely expensive, over $150.00 a month, but I knew I had to take them to rid my body of the acid that was creating the stones. After several months my legs and arms started to tingle and I would wake up with numb limbs. I researched the Potassium Citrate and found this was a side effect. I told my doctor I was going to stop taking the meds and asked if she would test my magnesium and potassium levels in two weeks upon my next appointment. I also bought and started taking your Oxy-Energizer. I started taking two daily and after 2 weeks the tingling and numbness was gone. My blood test results were better in all categories than any of my previous tests. I have been taking Pro-Caps for over a decade and tell everyone what reliable and great products you provide. There are a lot of companies that sell vitamins, but none that I trust more than Pro-Caps. What you identify is in your products I know I can trust, Thank you, for providing great health saving products, you are serving the people well... God Bless

ENERGIZING!! I originally bought this for someone that had hypokalemia, or low potassium. He had terrible stomach cramps and skin problems with blisters. I did a lot of research on the internet and figured out that he had this condition. This product has helped him a lot. He says that it has given him strength. While he was waiting for the product, he ate high potassium foods such as molasses, avocados, bananas, etc. I have also been taking it and have felt more energetic. Some reviewers mentioned taking it when they needed more energy. The label does say that its benefits are not felt immediately and are only realized after consistent daily use. So, it's best to take it every day. We've been using it for just over a week. I've been taking Andrew's supplements for about 10 years and love them!
