what it claims

Take an active role in your well-being by listening to your body's signals (fatigue, irregular cycles, difficulties conceiving): these indicators related to the reproductive sphere are often the first warning signs of deeper imbalances linked to lifestyle, even if your routine exams show normal results.

This approach of viewing the female cycle and fertility as a barometer of overall vitality is scientifically grounded.

This approach of viewing the female cycle and fertility as a barometer of overall vitality is scientifically grounded. A meta-analysis published in the journal BJOG shows that difficulties in conceiving are frequently correlated with variations in the body's energy and fat management. Similarly, an observational cohort study published in the Journal of the American Heart Association associates fertility history with the preservation of long-term cardiovascular vitality. The idea of listening to these signals before major discomforts set in is therefore very pertinent, as standard so-called 'normal' exams do not always capture subtle drops in health. However, while the pillars of well-being such as sleep, stress management, and nutrition are essential, the direct impact of 'toxins' on these delicate balances remains more difficult to quantify and is sometimes exaggerated.

What the graded evidence says

Evidence: B

Linked to, not proven to cause.

Effect: cycle regularity as a clinical health indicator — Endorsed by AAP/ACOG as a 'vital sign': deviations in cycle length, regularity or flow can flag underlying endocrine, metabolic or nutritional conditions. Qualitative guideline/consensus, not an effect estimate.
Measured on: adolescents and adults who menstruate

Cycle regularity is a useful general signal, not a specific test: an irregular cycle points to 'worth looking into', not to any one cause. Noli surfaces the idea and encourages tracking; a clinician interprets the specifics.
