What is HPU – and why it has far more to do with your health than you might think

Maybe you’ve already tried everything — eating healthier, checking your hormones, sleeping more, taking supplements… and yet you still feel exhausted, irritable, struggle with digestive issues, skin flare-ups, mood swings, or your cycle is completely out of balance.
If that sounds familiar, it may be time to learn about something that is barely acknowledged in conventional medicine — yet for many people is the missing piece of the puzzle:
What Is HPU?
HPU stands for Hemapyrrollactamuria.It is NOT a disease, but a metabolic pattern in which your body loses specific micronutrients through the urine — especially during stress or physical overload — without you noticing it.
The nutrients most affected are:
Zinc
Vitamin B6
Manganese
These three nutrients are key players in the body.If they are depleted, essential processes begin to struggle, including:
energy production & nervous system regulation
detoxification pathways (Phase 1 & Phase 2)
hormone balance
gut flora & mucosal repair
mood, skin health & stress resilience
And here’s the tricky part:Standard blood tests usually show nothing abnormal.Which is why HPU often remains undetected for years.
Typical Symptoms of HPU
Many people live with the effects of HPU without ever knowing it:
chronic fatigue or burnout feeling
brain fog & concentration issues
IBS symptoms, bloating, food intolerances
mood swings, PMDS, menstrual problems
acne, eczema or other skin issues
sleep disturbances & inner restlessness
histamine intolerance
muscle weakness
sensitivity to light, sounds, smells
feeling constantly overwhelmed
You don’t need to have all symptoms — sometimes just a few are enough to disrupt your metabolism.
Why HPU Is So Often Missed
It does not show up in a standard blood panel
It is not yet recognized as a classic medical diagnosis
Symptoms are often labeled as “stress” or “psychosomatic”
Complaints vary widely between individuals
Micronutrient testing is rarely done preventively
In reality, HPU is far more common than most people think.
Which Test Can Confirm HPU?
HPU is not diagnosed through blood work. The most important test is a simple urine test that measures the HPU / Kryptopyrrole value.
Supplementary blood markers can then help understand your individual needs:
active Vitamin B6 (P5P)
Zinc (whole blood)
Manganese
relevant liver & detox parameters
thyroid hormones (often affected as well)
I’m happy to guide you on which values are meaningful and how to interpret them.
HPU & Detoxification — How They’re Connected
If your body constantly loses Zinc, B6, and Manganese, your detoxification processes slow down:
Phase-1
enzymes become unstable
Phase-2
detox pathways get blocked
liver & gut become overloaded
toxins are cleared more slowly
oxidative stress increases
This often leads to:
skin issues
headaches
PMS
chronic fatigue
inflammation
digestive complaints
HPU & the Gut — A Critical Connection
In my practice, I see the same combination again and again:
➡️ HPU + gut issues
Why?
Zinc & B6 are essential for gut lining repair
deficiencies can contribute to leaky gut
weakened gut flora stresses the immune system
digestive enzymes work less effectively
inflammation develops more easily
This was also true for me:
I developed intolerances, bloating, brain fog, and unstable energy — and only after discovering my HPU, everything finally made sense.
My Personal Journey With HPU
When I received my own HPU diagnosis, it felt like someone finally turned on the lights. I suddenly understood:
why I reacted so strongly to stress
why my detox system ran slowly
why I had nutrient deficiencies despite eating well
why my digestion was unstable
I went through a 6-month detox & metabolic support protocol, which is typical for HPU, including:
targeted supplementation
gut-healing protocols
metabolic & liver support
stress & nervous system regulation
individualized nutrition adjustments
Yes — I experienced a temporary initial worsening, which is completely normal when the body starts regulating and balancing. But afterwards, everything improved noticeably:
more energy
fewer stress symptoms
clearer skin
more stable digestion
improved hormone balance
more inner calm & emotional balance
What HPU Is NOT
not a trend
not a psychological disorder
not “just a blood value”
not something to fear
not a disease that needs to be “cured”
HPU is a metabolic individuality — and once you understand it, everything changes.
How I Support You
I guide clients with HPU holistically through:
nutritional coaching
micronutrient rebuilding
gut healing
stress & nervous system support
TriloChi® & Laughter Yoga
emotional coaching
cycle & hormone support
I work especially often with women experiencing PMDS, hormonal imbalance, or chronic exhaustion — but my coaching is open to anyone wanting personalized guidance.
✨ You don’t have to function perfectly. But you’re allowed to start understanding your body.
