The "Free T" Problem: Unlocking Bound Testosterone
Share
Here is a frustrating medical fact: You might have "High Testosterone" on paper, but still feel low energy.
How? Because of a protein called SHBG (Sex Hormone Binding Globulin). Think of SHBG like a magnet. It floats through your blood and "grabs" your testosterone molecules. Once testosterone is attached to SHBG, it becomes useless. It can’t enter your cells to build muscle or give you energy.
The Key is "Free Testosterone"
You want Free Testosterone—the amount that is unbound and available to use.
How Longjack Helps
Eurycoma Longifolia, also known as Longjack or Tongkat Ali, has been shown in studies to help lower SHBG levels. By "distracting" the SHBG, it frees up more of your body's natural testosterone to actually do its job.
This is why we included it in Vitality Roots. We don't just want to help you make more testosterone; we want to make sure you can actually use it.
