From the kitchen cupboard
Sodium bicarbonate is in many Dutch kitchen cupboards, as baking soda. Bakers use it to make dough rise. A spoonful in water used to be a home remedy for heartburn. Bicarbonate occurs naturally in the body, as a buffer that keeps the acidity of the blood within narrow limits.
Almost a hundred years of research
As early as 1931, German researchers showed that test subjects who had taken sodium bicarbonate could keep going longer during strenuous exercise. Since then it has become one of the best-researched substances in sports nutrition. In 2018, the International Olympic Committee named sodium bicarbonate in a consensus statement as one of the few sports supplements with good evidence for an effect on performance.
From the stomach to the skin
The problem was always the stomach. To have an effect, you have to drink a considerable amount of sodium bicarbonate. Many athletes get stomach pain, nausea or diarrhoea from it. The American company Amp Human therefore developed a lotion that delivers the sodium bicarbonate through the skin, so that the stomach is bypassed.
PR Lotion
PR Lotion is the world’s first and only lotion that gives muscles more power, reduces fatigue, and promotes recovery by being absorbed through the skin. Using patented technology from Amp Human, the natural electrolyte sodium bicarbonate is delivered directly to the muscles. Sodium bicarbonate is so effective because it buffers the acid build-up in muscles that are working hard.
Benefits and function
PR Lotion helps you perform at a high level for longer and provides more muscle power, faster recovery and less muscle soreness. It allows a higher training intensity, so that you make progress faster. The function of PR Lotion is to counteract acidification in the muscles, so that you can perform at a higher level for longer. It also reduces muscle soreness and optimises recovery for your next workout.
Scientifically Backed
Several decades of research show that sodium bicarbonate is a safe and effective ergogenic aid. It is even recommended by the International Olympic Committee (IOC). Research shows that athletes using PR Lotion were able to perform 25% more high-intensity work, lift 16% more weight, and had a 53% reduction in muscle soreness (Delayed Onset Muscle Soreness, DOMS) compared to athletes who did not use PR Lotion. Some effects of PR Lotion can be felt within 30 minutes. With consistent use over several weeks or months, the effects will be stronger, and the best results will be visible.
Kelly Starrett on PR Lotion
Kelly Starrett, mobility expert and author of Becoming a Supple Leopard, is also a fan of PR Lotion: “We are a bit obsessed with how easy it is to use PR Lotion during our tough weekly workouts. We used to have to drink it, and that wasn’t really great. Now we simply rub PR Lotion on larger muscle groups before intense efforts to improve performance and reduce DOMS (delayed onset muscle soreness) after intense training. There’s a reason it’s called PR Lotion. Go faster and have less muscle soreness? You can see why we love it.”
Better performance and faster recovery
To make the most of PR Lotion, apply a generous amount to your muscles. Don’t be stingy! Once the sodium bicarbonate is absorbed through the skin, it remains active in the body for 5 to 6 hours. During this time, you can perform more and stay at a high level longer. The acidity that would normally set in earlier is delayed, preventing a decline in muscle function. If you use PR Lotion regularly, the effects of more intense workouts will compound, leading to faster progress. Don’t forget that your recovery is better too, so your starting point for the next workout will be improved!
