The goal of this clinical trial is to learn if stingless bee honey can be an augmentation supplement in Major Depressive Disorder (MDD) in adults. It will also learn about the adverse effects of the honey. The main questions it aims to answer are: 1. Is there any effect of SBH on depressive symptoms between intervention and control groups in MDD? 2. Are there any effects of SBH on BDNF between intervention and control groups in MDD? 3. Are there any effects of SBH on oxidative stress between intervention and control groups in MDD? 4. Are there any effects of SBH on verbal learning and memory between intervention and control groups in MDD? There is no placebo. Participants will: Take stingless bee honey or nothing every day for 2 months Visit the clinic once every 4 weeks for checkups and tests Report adherence and adverse effects of stingless bee honey on a self-reported online questionnaires

Depressive symptoms
Depressive symptoms will be assessed using Beck Depression Inventory Malay-version questionnaire, For total score, no depression (1 - 10); mild to moderate (11 -20); moderate to severe (21 - 30); severe (31 - 40); very severe (41 - 63).
Time frame: Before intervention, at week 4 during the intervention, at week 8 of the intervention
Oxidative stress
Serum malondialdehyde concentrations in blood will be assessed
Time frame: Before intervention, at week 4 during the intervention, at week 8 of the intervention
Brain derived neurotrophic factors, BDNF
Serum BDNF concentrations of blood will be assessed
Time frame: Before intervention, at week 4 during the intervention, at week 8 of the intervention
Verbal learning and memory
Verbal learning and memory will be assessed using Malay version of auditory verbal learning test. The highest of total learning (sum of A1-A5 trial) is 75 score which one words = 1 score and the highest for delayed memory (A7 trial) is 15 score
Time frame: Before intervention, at week 4 during the intervention, at week 8 of the intervention
Serum Interleukin-6
Serum IL-6 concentrations of blood will be measured using Elisa kit
Time frame: Before intervention, at week 4 during the intervention, at week 8 of the intervention
