Study summary

85 percent of women of reproductive age experience consistent period cramps/menstrual pain, and 60% indicate that they do not use painkillers to relieve menstrual symptoms; there is a need for natural and non-medicative supplements to dysmenorrhea. The purpose of this clinical trial is to examine the effect of 'Cramp Bites'--classified by a mixture of natural ingredients researched to help with period pain--on women suffering from primary dysmenorrhea: this will be done through providing participants with the snack and surveying them on how it changes their period symptoms.

Read the detailed description

Participants will be asked the following information at the interview: name, month and year of birth, ethnicity, email, and phone number. As well, they will be prompted for their lifestyle habits, allergies, prior pregnancies and deliveries, presence of pathological disorders, medication (specifically asking about oral contraception), use of over-the-counter painkillers for period cramps/menstrual pain, expected date of next period, and menstrual cycle history. They will also be asked to complete the Menstrual Symptom Questionnaire.

The baseline questionnaire will ask the participant about their prior experience with primary dysmenorrhea symptoms and with period cramps/menstrual pain on a sliding scale.

The daily questionnaire will ask the participant to rate the extent of their period cramps/menstrual pain, to describe their pain, and whether they have taken any drugs for their period pain on that day. This questionnaire will be completed by all participants starting 2 days before their next onset of menstruation. Participants were randomly assigned Cramp Bites or the Placebo Snack: all other protocols remain the same.

After their next menstrual cycle ends, participants will be asked to fill out a final questionnaire: this questionnaire will ask the participant if they have noticed any changes in their period pain, the efficacy of the snack, and if they have suggestions/comments about the snack. This study is divided into 4 parts. Some parts will take place at Cornell University, and other parts can be completed online.

Inclusion criteria

  • Women between the ages of 18 and 25 who experience primary dysmenorrhea and have no pathological disorders.

Exclusion criteria

Exclusion Criteria:

  • Pregnancy or breast feeding within 6 months
  • Primary or secondary amenorrhea
  • less than the 1st percentile or body weight above 300 lbs
  • Undergoing menstrual suppression by medicative means

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

What researchers measure

Primary outcomes

  1. Visual Analogue Scale for Spasmodic Cramps

    Participants rate their spasmodic cramp severity before and after eating either Cramp Bites or the Placebo Snack using the Visual Analogue Scale. This is on a scale from 0 to 10, where 0 represents no cramps and 10 indicates extreme abdominal cramping.

    Time frame: Participants complete this survey when they experience cramps: once before they consume their snack, and once after. Completion time for each survey is 7 minutes.

  2. Visual Analogue Scale for Congestive Cramps

    Participants rate their congestive cramp severity before and after eating either Cramp Bites or the Placebo Snack using the Visual Analogue Scale. This is on a scale from 0 to 10, where 0 represents no cramps and 10 indicates extreme abdominal cramping.

    Time frame: Participants complete this survey when they experience cramps: once before they consume their snack, and once after. Completion time for each survey is 7 minutes.

Secondary outcomes

  1. Menstrual Symptom Questionnaire (MSQ)

    Filled out during intake exam. MSQ indicates to what extent the participant suffers from spasmodic cramps, congestive cramps, or a mixture of the two.

    Time frame: Participants complete this questionnaire with a researcher before the study. Time to complete this questionnaire is 15 minutes.

Other outcomes

  1. Product Feedback Form

    Participants are asked to fill out a feedback form indicating how confident they were about their assigned snack's efficacy and the taste of the snack.

    Time frame: Participants were asked to fill out this survey at the end of the study. Completion time was 5 minutes.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 12, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
