Study type
Interventional
Description of intervention(s) / exposure
This study aims to compare a formulated honey designed to deliver benefits to people with type 2 diabetes over and above the benefit of honey itself. To this end kanuka honey has been combined with cinnamon, chromium and magnesium to create a honey dietary supplement that may deliver positive effects on blood glucose and insulin levels. 15g of honey orally is administered daily for 40 days containing 200 micrograms chromium, 120mg magnesium and 1.5g cinnamon. Adherence will be monitored by returned amounts of honey at the end of 40days. There will be a 20 day washout period between treatments.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After the baseline visit the order in which the honeys will be administered will be randomised. Allocation will be done by sealed opaque envelope, sequentially numbered.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Random sequence will be computer generated.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Crossover
Other design features
masking cannot be used due to the colour and aroma of the cinnamon
Phase
Not Applicable
Type of endpoint/s
Efficacy
Statistical methods / analysis
ANOVA for area under the curve glucose and insulin from baseline OGTT, then for differences between baseline and 40 days for all variables. A 2 arm crossover trial requires multiples of N=2 as there are 2 possible orders of treatment administration. Previous data on the variability of measurements of glucose tolerance and insulin sensitivity were used to calculate required sample size. Calculations performed using a one-sample T-test and a 2 sided type-1 error rate of 5% revealed a sample size of 12 would be 90% powered to detect a clinically significant difference between the treatment groups.

Summary
Brief summary
This study aims to compare a formulated honey designed to deliver benefits to people with type 2 diabetes over and above the benefit of honey itself. To this end kanuka honey has been combined with cinnamon, chromium and magnesium to create a honey dietary supplement that may deliver positive effects on blood glucose and insulin levels. This formulated honey will be compared with ordinary kanuka honey firstly in an oral glucose tolerance test for acute glucose and insulin response, then over 40 days in an intervention.
