I want to start taking 4mg of biotin a day but I have no idea if there is a toxicity level.
Also I read in a post about biotin causing erratic heartbeats for some ppl and throwing off the menstrual cycle.That sounds bad to me.
Can anyone who has taken over 3 mg of biotin please repsond and tell me if they had negative side effects?or if they just got tons of growth
