Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1: 200mg tocotrienol rich Vitamin E from palm oil
Dose: 200mg once daily
Duration: 3 months
Mode of administration: Oral capsule
Active ingredients:
1) Gold Tocotrienol E 70%
2) Yellow palm superolein

Adherence will be assessed by counting the remaining capsule brought back by the participants during the follow-up visits. In addition, the plasma Vitamin E levels will me measured to assess adherence of the participants.

Outcomes
Primary outcome [1] 329129 0
Blood samples will be withdrawn from participants during the visits for data analysis.
Changes in Vitamin E levels (Tocotrienol and Tocopherol) in the blood will measured using high performance liquid chromatography (HPLC).

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)
Allocation will be concealed by numbered containers.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratified allocation will be employed in this study. The participants will be stratified according to their gender, age and HbA1c levels. Allocation of subjects will be done by simple randomisation using a randomisation table created by computer software (i.e computerised sequence).
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data

Safety/efficacy
Statistical methods / analysis
The total sample size of the study is 240 participants. Each cohort (active vs placebo) comprises of 60 participants with an allowance of maximum 2 dropouts per cohort. This number is derived from an online sample size calculator available at: http://clincalc.com/stats/samplesize.aspx.

Statistical analysis such as ANOVA and t-test will be done using SPSS version 25.
