Secondary outcome [3] 390550 0
The participant's activity levels will be noted using a self-reported simple questionnaire ( how many hours a week, are you spending doing atleast moderate physical activity?) and rated based on the below Ministry of Health’s guidelines for adults, as to whether they are physically active or at present have limited activities level.

Physically active people are defined as someone who will do at least 2 ½ hours of moderate or 1 ¼ hours of vigorous physical activity spread throughout the week.

-Moderate intensity is defined as an activity that causes a slight but noticeable increase in breath and heart rate. You can still carry on a conversation.

-Vigorous-intensity is an activity that makes you out of breath – you can't do these activities and chat at the same time.

Summary
Brief summary
We are planning a Pilot study to look at the effectiveness of ingesting a multistrain probiotics for eight weeks in the treatment of Major Depressive Disorder in community along with conventional biological treatment, antidepressants.Apart from the above, study also tries to clarify whether there will be a change in the levels of inflammatory markers called interleukin 1 and 6 due to the above intervention and does people's eating and lifestyle have any confounding effect in the above relationship.

Public notes
Although probiotics are used over the counter for the above condition, understanding this relationship better within the evidence based framework will boost the possibility of a more Holistic treatment to this condition in the near future. it will also help us in getting approval from Governments to consider funding this treatment option.
