Fitness InsideTracker refresher test
Loss of strength and mobility can begin as early as age 30. By optimizing biomarkers related to fitness, you can extend this age.
Want to maximize your strength, muscle growth and recovery and continue to monitor your results? This blood test analyzes key biomarkers that affect hormone balance, energy levels and muscle recovery so you can improve your fitness performance in a targeted way.
What is being tested?
- Testosterone - The most important muscle-building hormone, essential for strength, recovery and energy.
- Free testosterone - The active part of testosterone that is readily available for muscle growth and performance enhancement.
- SHBG (Sex Hormone Binding Globulin) - Regulates the availability of free testosterone; excessive SHBG levels can slow down muscle building.
- Cortisol - The stress hormone that when chronically elevated can promote muscle breakdown and fat storage.
- Vitamin B12 - Plays a crucial role in energy metabolism, muscle function and endurance.
- Folate (Vitamin B9) - Supports red blood cell production and contributes to oxygen transport to muscles.
- Albumin - A protein that aids in muscle recovery and plays a role in hormonal balance.
Additional option for women
For women, it is possible to expand this test to include:
- DHEA-S (Dehydroepiandrosterone sulfate) - A precursor hormone that contributes to the production of other hormones, such as estrogens and testosterone.
This extension is easily added via the slider.
