Why Probiotic Effect
Formulated with Dr Darija Strah, gynaecologist & obstetrician Meet the doctor →The problem
Modern science reveals a strong connection between gut health and hormonal balance. The gut is not only responsible for digestion — it is the centre of the immune system, mood regulation and even hormone production.
When gut flora is out of balance, digestion, nutrient absorption and comfort suffer.
Beneficial bacteria that renew gut flora — key for optimal digestion, better nutrient absorption and reduced bloating.
Beneficial gut bacteria help metabolise hormones like oestrogen. A disrupted microbiome can lead to imbalance.
An essential component for stabilising hormones and improving insulin sensitivity.
Imbalance can show up as irregular cycles, fatigue, mood swings and weight changes.
Plays a crucial role in cellular functions and additionally supports reproductive health.
The whole body feels the consequences when key minerals and vitamins fall short.
Magnesium for normal psychological function, zinc for fertility and reproduction, chromium for normal blood glucose and vitamin D for healthy bones and teeth.
The mechanism
When the gut microbiome is balanced, the conditions for successful hormone regulation are created.
The solution
Two products that work together — Complete Biotics for your gut flora and My Cycle for hormonal balance. With a small change in your daily routine, you take care of the root, not just the symptoms.
