A few years ago while on holiday in Majorca, I suffered from painful night cramps in my legs. I went into the local pharmacy and asked the chemist for something and she said "Ah! Magnesio. One glass every night." She sold me a tube of fizzy magnesium. It was difficult to find the product in London but I logged onto Higher Nature and voila! there was Fizzy Magnesium. No more cramps and even my MS sufferer husband ehas been prsuaded byhis consultant to take it to stop his twitchy legs at night. Two happy consumrs and delighted that I can get the product in the UK.
