after taking this everyday for a week, i frequently feel a "half a second falling sensation" everyday. at first i thought i may be getting some illness, and i know it is not Vertigo as i had Vertigo before. i also do not want to go to the doctor as they may be alarmed and put me through many expensive tests to investigate. i googled a bit and it says it is due to stress, nothing to worry about. but i am healthy and not stressed, so i start to think what was it that i had started to intake and i traced it to this supplement. i stopped taking and two weeks later that sensation is gone. my husband is taking too but he is fine. i am writing this so that if anyone feel some weirdness or slight giddiness, it could be this
