Yes it is better to increase the dose if antibodies
are high as you have to maintain the level of TSH
below 3 which you are maintaining already but high antibody titre indicates there is requirement of more dose.
Thyrowel tablet contains supplements and can be tried daily one tablet after dinner as it controls the antibodies
Dietary supplements like fish oils , omega 3 fatty acids , Vit B12 , Vit D and calcium intake should be increased
