#76749, Thank you for sharing your story. Will you please let us know what brand of kelp you are taking? I have AFIB and I'd like to try what worked for you. I found you by searching for CoQ10 and palpitations, which led to this article. It might be the brand I was taking, but I suspect the CoQ10 for the palps I've had recently, so I'm discontinuing it, as you did. I have some thyroid anomalies and have suspected Iodine might be beneficial. Will you help with the brand, please? Thanks, Tom
