The Cycle and us – A Self-Experiment

13.02.2026

Perhaps you know the feeling: Once a month, everything changes. Your mood fluctuates, your body feels heavy, and concentration becomes a challenge. For many of us, this is part of everyday life – yet we rarely talk about it. Cycle-related complaints are widespread but are often underrepresented both socially and scientifically.

Why This Self-Experiment?

The research motivation is quickly explained: Many over-the-counter supplements promise relief from PMS symptoms, but their effectiveness is often insufficiently proven. At the same time, there is a lack of systematic recording of what we actually experience.

This article describes a non-representative self-experiment – an observational study without a control group. The goal is not evidence-based efficacy testing, but rather structured symptom recording with an exploratory character. It is about recognizing patterns, understanding connections, and above all: taking one's own experience seriously.

Study Design

The study spanned three menstrual cycles per participant:

Cycle

Phase

Documentation

Cycle 1

Baseline without supplement

Symptom recording with PMSS

Cycle 2

Supplement A intake

Symptoms + bleeding data

Cycle 3

Supplement A intake

Comparative analysis

Each participant took a different supplement – from magnesium to Vitex to specialized nutritional supplements. Symptoms were recorded throughout the entire cycle, based on the Premenstrual Syndrome Scale (PMSS). Additionally, we documented:

  1. Bleeding duration and intensity
  2. Mood changes
  3. Physical complaints
  4. Sleep quality and energy levels

What We Discovered

The comparison between Cycle 1 (without supplement) and Cycles 2 & 3 (with supplement) showed interesting patterns. Many participants reported subjective symptom relief – especially regarding mood swings and sleep disturbances.

However, something else proved particularly valuable: Systematic documentation helped identify previously unconscious connections. “I never consciously noticed how much my concentration declines in the second half of my cycle,” reported one participant. “The tracking helped me plan my daily life better.”

Scientific Classification

It is important to clearly define the limitations of this self-experiment:

  1. No statistical significance
  2. No generalizability to other women
  3. No causal evidence

The knowledge gained is limited but potentially hypothesis-generating. This means: We cannot derive universally applicable recommendations, but we can raise questions that stimulate further research.

Why This Matters

Cycle-related complaints cause real suffering. Even if they do not represent a disease, they are a legitimate topic for research, visibility, and care. Systematic documentation is a first step toward taking complaints seriously and investigating them better in the future.

For each of us who lives with these symptoms monthly, this is not an abstract research question – it is everyday reality. And that reality deserves to be heard and taken seriously.
