To get detailed portrait of the human body’s internal biochemistry, it is helpful to understand how biomarkers impact each other. In this article we investigate recent scientific literature looking at how testosterone levels are affected by a commonly overlooked biomarker: the mineral magnesium. Read below to learn the importance of each biomarker and how monitoring magnesium can boost testosterone and improve muscle growth, sex drive, and overall health and wellness in both men and women.Read more
If you could tap into >40,000 calories of your fat fuel during endurance exercise instead of relying on your maximum 2,000 calorie storage of carbohydrate fuel, would you do it?
What if it meant no more liquid gels, sugar-containing sports drinks or bananas to give you that energy boost when you're on the verge of exhaustion? If LeBron James did it. Was it really a wise choice based on current science?Read more
We get a lot of questions about the uses of whey protein. As a result, we did some nitty-gritty research on how this protein can potentially impact levels of the 30 blood biomarkers that InsideTracker monitors. In this first blog post of a three-part series, we will explain research examining how the consumption of whey protein may be a valuable intervention in reducing chronic stress by regulating levels of cortisol and serotonin.
Before we do that, we will define what chronic stress actually is and then look at the chemical structures and physiological functions of whey protein, cortisol, and serotonin. Continue reading below to see the research and learn how InsideTracker can both monitor your biomarkers and provide you with well-researched interventions to get them to optimal levels.Read more
Suzie Snyder joins the ranks of world-class athletes like Sarah Haskins, Jarrod Shoemaker, and Ruben Sanca who have used the InsideTracker program to increase their speed and improve their strength. As a professional off-road triathlete, Snyder is no slouch when it comes to her physical fitness. In addition to getting her certification as a strength and conditioning specialist (CSCS), she has a master’s degree in exercise science and a deep knowledge base of human physiology and nutrition. However, she wasn’t sure about the best approach to take in improving her physical performance.Read more
For women, the role of testosterone in the body is not always clear. Here is some basic information that every woman should know about this mighty hormone... and why it's not just for the boys.
What is testosterone?
Testosterone is a steroid hormone that belongs to a class of hormones called androgens. It is produced mostly in the testes of men and the ovaries of women, although small amounts are produced in the adrenal glands as well. Testosterone is best known for its anabolic effects, like building muscle and tissues, helping with protein synthesis, and increasing bone density. Testosterone also has androgenic effects that we often associate with male secondary sex characteristics, i.e. deepening of the voice, development of facial and body hair, and changes in facial bone contours.Read more
Athletes spend a considerable amount of time and money trying to find the right sports drink, nutrition bar, or protein powder that could give them the extra edge during a competition. Here’s a little secret: knowing your biomarker status might be a more efficient way of improving your athletic performance than any other product on the market. Whether you’re a professional athlete or a weekend warrior, getting a sufficient amount of good sleep can help improve speed, accuracy, and reaction time.
I believe in and practice a methodical approach to athletic performance. I control what I can control, and have faith in myself, my training, my body, and my craft. I believe in inspirational athletic feats and heightened states of athletic performance. I know these states exist and they are almost impossible to duplicate or explain. How do you explain what it means to be in “the zone”? It’s obvious to anyone watching when an athlete is in “the zone.” The athlete moves freely and effortlessly, transcending boundaries and defeating opponents. It’s a special thing to witness and a special thing to experience.Read more
Testosterone is a steroid hormone that is essential for muscle development and strength, bone health, sexual function, overall energy, and athletic performance. Although both men and women produce testosterone, women normally have very little of this hormone - a fraction of the amount that men typically have. However, having too much or too little testosterone can cause problems. Excess testosterone decreases the levels of HDL (good) cholesterol, affects heart health, and impairs sexual and reproductive function. In contrast, low testosterone can make you feel tired, uninterested in sex, and less competitive, as well as diminishing your athletic performance. Possible causes of low testosterone include overtraining and low levels of zinc and magnesium.Read more
It’s easy to see why InsideTracker can be beneficial for professional athletes like Sarah Haskins, Jarrod Shoemaker, and Ruben Sanca, who have to keep their bodies in the best condition possible to rival other world-class competitors. Even a small change in nutrition can improve performance and turn a good effort into a winning one. But InsideTracker also offers big benefits to other people—especially individuals like retired Master Sergeant (MSG) Joseph Roberts, who knows how important it is to stay healthy before, during, and after long military stints in Iraq.Read more
Is your energy low? Don’t just chalk it up as “one of those weeks”—you might be deficient in certain nutrients! Fatigue is a common complaint for many individuals, and it becomes more common with age. Fortunately, there are plenty of simple ways to boost your energy levels, but you need to find out what’s going on inside of your body first.
