Hidden Stress Marker – Kryptopyrrole
Kryptopyrrole in urine carries vitamin B6 and zinc out with it. People under long-term stress and oxidative imbalance are often losing these two key nutrients continuously without realising it.
Worth testing if:
- Long-term anxiety, irritability and poor sleep
- Big mood swings, and you crumble as soon as stress hits
- White spots on your nails, and wounds that heal slowly
- You supplement B-complex and zinc yet never feel it is enough

What this test is for
Using the kryptopyrrole concentration in your urine, this test assesses whether long-term stress and oxidative imbalance are accelerating the depletion of key nutrients such as vitamin B6 and zinc.

Frequently asked questions
Isn't unstable mood purely a psychological issue?
Not only. The stress response also drives the loss of specific nutrients, which in turn affects neurotransmitters and emotional stability
Isn't taking a B-complex and zinc enough?
If a metabolic by-product such as kryptopyrrole is running high, supplementing may still not keep up with the rate of depletion. You need to find the root cause first, then adjust dose and form
Isn't a urine test unreliable?
Kryptopyrrole is an established parameter in functional medicine for reflecting stress-driven nutrient depletion. It is especially suited to interpreting psychological symptoms, nutrient deficiency and chronic tension together
