I can’t get molybednum either! (well I can’t afford the conversion of US dollars to NZ and get it shipped here 🙁 )
I find oil pulling like you are doing seems to help, and having epsom salt baths, and getting plenty of sleep.
One of the pros will be able to help you better I’m sure! 🙂
ETA I have no idea if thrush can happen as a result of die off, really hope someone can help you with that!!
