By tracking your biomarkers at regular intervals through our online dashboard, you can:

  • Track your fatigue levels
  • Avoid over-training
  • Monitor your immunity
  • Reduce injury risk


See how a simple test can improve your performance...

Over the past 4 years I’ve suffered with a number of serious knee injures from ski racing at an International level. My rehabilitation and training can be very demanding - up to 16 hours a week in the gym lifting weights or on the bike. When I’m skiing, I can easily rack up 30 hours per week. Therefore, it’s important I can regularly monitor key biomarkers for immune function and fatigue including vitamin D, iron, and thyroid function. This allows me to make informed decisions about my training, recovery and nutrition, so I can stay healthy and perform at my best.

I enlisted the help of Forth to help me get to the bottom of my current health concerns. The test is really easy to do, just provide a small blood sample from the comfort of your own home and pop in the post. Within 3 days Forth emailed my results back to me. I can’t thank Forth enough for dealing with my results so quickly which has meant I can take the action needed to get my hormones back to normal
