Vitamin B12 Deficiency & Pernicious Anaemia
Mendus projects are completely free or involve minimal cost (e.g. the price of whatever you're testing). Studies are done from your own home, following our guidelines. Each study is listed on the 'Project Board' below and has a description further down.
ACTIVE - you can officially join the study and begin at any time
PENDING - we have enough interest but the study isn't ready yet
PROPOSED - we are waiting to see if enough people are interested
COMPLETED - there was no need to keep the study open

How Treatment Parameters Relate to Symptoms
This survey assessed vitamin B12 use in ~200 pernicious anaemia and/or vitamin B12 deficiency patients and has now been published. Each person was asked to report as many discrete epochs of B12 use as possible, defined as periods of B12 treatment (i.e. characterized by the type of cobalamin used, frequency of use, administration route and dosage). A list of 20 symptoms were rated for severity, for each epoch entered. The results of the survey are currently under review for publication and therefore not displayed on the results page. In brief we found that oral B12 was not as effective as injections, that injections work better when administered more frequently and that folate is very important for symptoms relief.
