Bestrong, l get it from ebay, they send it from America, just type "Sal de uvas Picot" in the search bar.
But Nexium, Bicarbonate Soda, Picot l use then when l want to have foods that l know l shouldnt, because they cause me heartburn, like bread (any flour), potatoes, coke, coffee, so the healthiest thing would be to be on a diet to avoid foods that cause you heartburn, l guess...
