Vomiting
Adverse effectVomiting is an adverse body-related effect in which stomach contents are expelled through the mouth. It describes the act of being sick itself, rather than a possible cause, underlying condition, or treatment goal.
A focused overview of vomiting as a body-related health effect.
These are research findings, not promises. Most options have little evidence, and results differ from person to person.

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

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
Vomiting is an adverse body-related effect in which stomach contents are expelled through the mouth. It describes the act of being sick itself, rather than a possible cause, underlying condition, or treatment goal. It may be reported in connection with interventions such as Zinc, Saffron Extract, Vitamin B9 (Folate), and Vitamin E.
How interventions help
The interventions associated with this outcome are linked to causing vomiting rather than reducing it. They include supplements and a procedure, so the reasons for the association may differ: some findings reflect adverse reactions, while others are described in relation to gastrointestinal irritation or fluid and electrolyte loss.
Dose varied across the evidence, so these findings do not establish a single dose threshold at which vomiting occurs. No consistent duration of use, time to onset, or persistence after stopping is provided, and the available findings do not show that continuous use is required.
The evidence comes from both clinical research and pharmacology references. Some clinical findings are consistent across studies, while at least one intervention has conflicting evidence, so the strength and reliability of the association are not uniform. Health status was not specified for the interventions, meaning the findings cannot be assumed to apply equally to every population or situation.
Choosing guidance
When comparing these options, pay attention to the context in which vomiting was observed rather than treating every entry as equivalent. Several reports relate to excessive, concentrated, higher-dose, or large oral amounts, while others involve prolonged use, injectable administration, or systemic or rectal treatments. This makes the amount, preparation, and route important when interpreting the possible association.
The evidence is not uniformly human or equally direct. Some options are supported by clinical research, including randomized trials or meta-analyses, whereas others rely on pharmacology references, theoretical reasoning, anecdotal reports, or small case series. Many studies do not specify the health status of participants, so their relevance to a particular person or situation may be limited.
Timing and duration are also inconsistently reported. The available findings generally do not establish how quickly vomiting appeared, how long it lasted, or whether risk changed consistently with continued use. Where studies conflict, the association should be viewed as uncertain rather than settled; this is specifically relevant to Saccharomyces Boulardii.
For a reader prioritizing human evidence, options supported by clinical studies provide a more directly relevant basis for comparison than entries based only on reference material or anecdotal reports. For a reader concerned about gastrointestinal tolerance, the most relevant context is whether vomiting was linked with large amounts, concentrated preparations, higher doses, prolonged use, or a particular route of administration. These distinctions help frame the listings but do not establish that vomiting will occur in every person.
