Amenorrhea
Amenorrhea is a condition in which menstrual periods are absent. It is categorized here as a hormonal condition, which means it can be related to changes in the body’s hormone balance.
Amenorrhea is a hormonal condition. This page gives a simple overview and notes its relation to Vitex Agnus-Castus.
This list shows research findings, not treatments. Nothing here replaces medical care. If you have this condition, talk to a doctor.

How to read the evidence
Evidence tier — overall strength of the evidence for the whole compound
- StrongWell established — backed by strong, consistent human research.
- ModerateSome genuine support, but mostly from small or lower-quality studies. Promising, not proven.
- PreliminaryEarly-stage evidence — a promising hypothesis, not an established effect yet.
- LimitedVery limited evidence — treat this as a hypothesis, not proof.
- InsufficientNot enough good evidence to draw conclusions yet.
Certainty — how sure we can be that the effect is real
- Very highVery sure — strong, consistent evidence
- HighFairly sure — consistent evidence from good studies
- MediumModerately sure — new studies could change this
- LowNot sure — little or mixed evidence
- Very lowVery unsure — almost no usable evidence
Source — where the data comes from
- Meta-analysisPooled analysis of many trials — the strongest evidence
- RCTRandomized controlled trial — a strong human study design
- ClinicalA human clinical study
- Reference knowledgeFrom general health-science or pharmacology references, not a study of this exact claim
- Animal researchStudied in animals, not humans
- Community reportsAggregated user reports — anecdotal signal, not evidence
- TheoreticalMechanism-based reasoning, not yet tested
Study grade — quality of each underlying study (A best, D weakest)
- AHigh-quality — strong, consistent human trials
- BGood — solid evidence with some limitations
- CModerate — limited, small, or mixed-quality studies
- DWeak — preliminary, indirect, or animal-only
Confidence — how strongly the sources back a finding
A 0–100 score from study quality and agreement
Most supplement evidence is graded C–D. Read it as preliminary signal, not proof.
Full write-up
What is it
Amenorrhea is a condition in which menstrual periods are absent. It is categorized here as a hormonal condition, which means it can be related to changes in the body’s hormone balance.
This page includes two entities that may be discussed in connection with amenorrhea: Vitex Agnus-Castus and Clomiphene. For any case of absent periods, a clinician can help determine the cause and whether it needs evaluation.
Evidence-backed options
For amenorrhea, the available evidence-backed options in this data are limited. Clomiphene and Vitex Agnus-Castus are both listed as helping, but the evidence level is very low and comes from a pharmacology reference rather than stronger clinical evidence. That means they appear in reference materials as possible options, but the support for their use is not robust.
Because amenorrhea can have different causes, the most relevant option depends on why periods have stopped. This summary does not indicate which option is appropriate for any individual case, and it does not replace evaluation by a clinician.
