Thrush and white tongue are two different things.
sorry, for not using the right word. But I’m pretty sure that what he has is thrush, even though not a very bad one. But googling “thrush” and looking at the pictures it looks quite similar. I don’t know, I guess he just has to try longer… maybe the thrush now is not a Candida growth symptom anymore, but a die-off symptom?
Thanks Raster for the information. I will get the supplements for my boyfriend.
