DUTCH Plus

For the athlete who's fatigued despite rest, stuck in a plateau, sleeping poorly, or noticing changes in drive, mood, or cycle. The DUTCH Plus uncovers the hormone and stress patterns behind those symptoms — your cortisol rhythm across the day, your cortisol response at waking, and your sex hormones, including how your body makes and clears them. It reveals whether your stress system is keeping up with your training, and flags nutrient gaps, oxidative stress, and gut imbalance. An at-home urine and saliva test for what standard labs keep calling 'normal.'
