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 heart 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.

Night Leg Cramps I rated a 5-star first off because Andrew has yet to fail me with his quality supplements, .... and I am a loyal fan of nearly 15 years! My husband and I are in our late 50's and of course with aging comes the typical aches/pains......and sleep-disrupting leg cramps!!! I've done plenty of research to understand that Potassium and Magnesium are important for so many reasons, ......and surprisingly enough, including helping with leg cramping! So, only trusting Andrew's products, we are giving this Oxy-Energizer a fair trial. I also take Ultimate Calcium-Magnesium (2 capsules nightly), so combining with the Oxy-Energizer will take some careful planning as I can sometimes get diarrhea with too much Magnesium. But---to help with or even eliminate nighttime legs cramps is worth trying. Maybe we will take the Oxy-Energizer during the day or a few hours prior to bed. Fingers crossed!!!

Helps Improve Sleep Since taking the Oxy-Energizer, my sleep has improved tremendously!!! I read an article that said magnesium helps improve sleep so I thought I would give the Oxy-Energizer capsules a try. I have been taking these for about a month and can tell a major difference in my sleeping pattern. I also experimented with going a night or 2 without a dose and noticed my sleep was interrupted and less relaxed. I take 1 or 2 capsules about 15 - 30 minutes before bed and I have a restful sleep. Great alternative to other sleep enhancers.

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.
