it's difficult to ascertain whether you are a man or woman from your name...you don't give an age...it could be a thyroid issue or hormonal depending on what phase of your life you are going through...are you getting good sleep?
it's unrealistic to ask for health information this way, you are very vague about why you cannot get tests from your own physician.
my vitamins didn't do me much good until I switched to a high quality easily absorbed capsule type...the hard ones were just "passing through" not even fully dissolving...and a pill is not a substitute for a good diet.
