I am feeling week from past couple of months. Might be due to current pandemic situation, working has increased to 11-12 hours with very less movement. So recently started basic push-ups from past 2-3 weeks and feel more tired for complete day. Seems like lack of exercise and no proper diet time, is causing this issue. So can you suggest some good multivitamin which can be taken for general health improvement, so that can get back to my normal health ? Market is full of different brands multivitamin but looking for trusted and genuine multivitamin.
