Lamberts MSM 1000mg From  £13.50

I use MSM for Sinusitis and clearing any kind of runny nose symptoms, and it's excellent. After trying many chemist bought medications, this was the only thing that allowed me to breath through my nose within an hour of taking it. I particularly like this brand as it's from a natural source and is such a good price.

...service from start to finish. As for the effectiveness of the actual product, it is yet too soon to say.
