Hydroponic Fortification and Dietary App Effect on Nutrients Level (Harvest)
United Kingdom52 participantsStarted 2023-05-04
Plain-language summary
Veganism and vegetarianism have clear benefits where they have a lower risk of many health issues. However, they also have a higher risk of nutrients and vitamin deficiency such as iron and vitamin B12. Iron can be found in plant-based food but in varying quantities, whereas vitamin B12 is mainly found in red meat, thus vegans and vegetarians can only take this vitamin in supplements such as tablets. In this study, the investigators are testing two interventions, the consumption of recipes with a certain iron amount to increase iron levels, and the consumption of vitamin B12 biofortified plants to increase serum B12 levels in vegan and vegetarian participants.

Inclusion criteria
. Women over 18 years with a regular menstruation cycle (\>21 and \<40 days).
. Has followed a vegan or vegetarian diet that does not include the consumption of meat or fish for at least 1 year.
. Willing to remain on their background diet for the duration of the study.
. Those who are on a routine regimen of iron and/or vitamin B12 supplements must maintain the same doses 3 month prior to the study and during the duration of the study.
. SF \>15 µg/L and \<60 µg/L \[WHO uses the following cut-offs for context: below 15 µg/L indicates iron deficiency, 16-40 µg/L indicates borderline deficiency, and 41 - 150 µg/L is normal\].
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
