why are you taking supplements if you have healthy diet! your age and bmi details would have been more helpful to advice you. get a blood test done to check for your iron levels, vit b12 and vit d levels. get a cardiac evaluation done just to be sure that you dont have any cardiac problem causing this fatigue. too much of anything is too bad.. so unless you have any deficiency i would suggest not to take supplements.. once you are sure that you dont any cardiac problem ,then you should start excersing mre to increase your metabolism and to stay fit.. hope i answered your query .. do rate my answer. thank you.
