Biotin issues

Hi guys

been taking biotin for around 3 months now, not sure if it works or not as not diagnosed yet

have any of you had any issues with heart palpitations while on it? I’ve had these misbeats before but recently I have had a lot more and they feel harsher. I’ve been taking 300mg a day split in 100mg thre times, read online that biotin can cause palpitations and wanted to know if anyone else has had this?

Tried them myself. Didn’t do let for me. No side effects. Stopped taking now
