While sweat rate is generally linked to size (larger athletes typically sweat more) and gender (males sweat more than females), the concentration of electrolytes in sweat is uncorrelated. Two similar athletes can have different sweat rates and sweat composition, and the electrolytes lost can vary over 200 fold.
Electrolyte depletion can lead to a gradual and subtle loss of performance. As electrolyte depletion becomes more extreme, debilitating muscle cramps can suddenly set in. For every athlete, the point at which performance decreases or muscle cramps start is different. Athlete sweat testing & sweat composition analysis is the only way to know what your body’s specific needs are.
Athlete sweat testing is critical for optimizing performance and minimizing heat-related injuries. Knowing your exact needs takes the guess work out of fluid and electrolyte replenishment, allowing you to maintain peak performance, to prevent heat-related issues like muscle cramping, and to focus on other aspects of your game.
Just like elite professional & collegiate teams and athletes, you can now determine your Individual Sweat Profile, and end the electrolyte replenishment guessing game. Our LEVELEN™ Electrolyte Replenishment System (ERS™) is the only integrated solution of sweat testing and electrolyte replenishment products customized to your specific needs.
After performing an Athlete Sweat Test, you will receive your Individual Sweat Profile. Your Sweat Profile details your hourly hydration strategy and specific recommendations of LEVELEN™ products that are customized for your specific electrolyte replenishment needs.
We recommend that serious athletes test twice a year (pre-season and mid-season), and more frequently (quarterly/monthly) for those that train/compete in very different climates and conditions.

[In 2005], a lady named Sandy (Dr. Sandra Fowkes Godek) came to me after it was recommend that I get help with cramping problems I was having when trying to perform on the field. I had tried everything, and I hydrated as much as I could, but nothing worked. Sandy sweat tested me and recommended LEVELEN Level 5, which I started to take before my practices and games. This is the best part, my cramps were immediately gone. Being a (11) year veteran in the NFL, I take my job very seriously. I want be at peak performance when competing.
This past weekend I played in a charity tournament at my local rink. 6 games in 4 days was a tall order, but the Levelen I had kept me hydrated and never at a loss for energy. I’ve suffered from dehydration-related migraines in the past and had no such issues here. My level-4 strawberry citrus powder has worked wonders and is now an essential on game days and for workouts. Tastes great and truly does work, and after being an advocate for Biosteel for a long time, I now have a product that is tailored for me and truly works.
Since I started using LEVELEN 3 electrolyte hydration before my workouts, I have seen a big difference in my energy level and my performance during workouts. Unfortunately, working in the industry I work in, drinking the amount of water I need is not always easy but with adding LEVELEN to my water before I work out has been key to my performance. It is not something I find I need every single day, but definitely with the hot weather coming I have found myself using it more and more. I would recommend everyone get their sweat tested,
Two years ago after playing two ice hockey games and one indoor lacrosse game all in the same day, I was hospitalized due to severe dehydration. My legs cramped up so bad that I was unable to walk, so they rushed me to the emergency room by ambulance. Once released from the hospital, I was introduced to the Philadelphia Flyers Strength and Conditioning Coach, Jim McCrossin. He was made aware of my condition by my coaches with the Team Comcast ice hockey organization. Jim talked with me about hydration and the ability to manage it to maximize my performance while balancing my levels.
Two years ago during training camp, I met Mrs. Sandy (Dr. Sandy Fowkes-Godek). She told me they were testing players that lost large amounts of weight during practice. So I was an obvious choice for her study. I was consistently losing 10 lbs a day during those long and hot practices. I was advised to consume Level 4 of LEVELEN, to help combat dehydration which had started to set in. After about a week of hydrating with LEVELEN, and my normal gallon of water, I became more alert due to the fact I was fully hydrated.
I participate in long distance X-country mountain bike races. I’ve always had trouble with cramping on these hard rides, typically around the 4-hr mark. I got sweat tested by LEVELEN, and began using LEVELEN Level 3 while riding. I am confident that their products, which are tailored to your personal specific mineral and electrolyte losses, were integral to my success at the Leadville Trail 100, where I completed the 104 mile course, with 12,500 feet of elevation gain in 11:37:52 without one single cramp!

I had an outstanding performance using LEVELEN 4 during during the Amica Marathon this past weekend!!! I recently incorporated Levelen 4 into my long distance training plan and the results have been great!!! For the first time, “the wall” never came!! I couldn’t be happier! Thank you for your help!
I had one of my best seasons in 2013 thanks in part to the LEVELEN team. Cramping during races has always been a problem for me, and after researching the potential causes, I tried every possible solution including different nutritional strategies, training styles, and pacing strategies. Nothing seemed to work, and I thought, perhaps due to my genetic susceptibility, that I would always have to deal with my cramping. Then, I met Sandy from HEAT Sport Sciences, and she convinced me to get tested and try out LEVELEN for the second half of my 2013 racing season.
LEVELEN is a recent addition to my necessity list. The only thing that rivals the importance of my workouts, is how I RECOVER from those workouts. Hydration is my primary focus when recovering. Subsequently, so is my LEVELEN Electrolyte powder.
Your body can’t utilize or retain water if you don’t consume electrolytes. I’ve found that most electrolyte powders are better for hydration than just drinking water by itself. That being said, most electrolyte powders taste awful. I found that I could hardly choke some down. Replenishing my electrolyte intake requires a lot of unnecessary energy when it tastes unpleasant.
I began working with the LEVELEN team to get a more detailed understanding of the concentration of electrolytes in my sweat during exercise. While it’s simple to determine your fluid loss, it’s not simple to know the concentration of the sweat and what the actual replenishment needs are. The sweat test kit is very simple and straight forward, and the results were clear. I had some follow-up questions, and LEVELEN was quick to reply and answer everything. It’s clear that the LEVELEN team is all about the science and fine-tuned needs of athletes when it comes to electrolyte replenishment;
