Jamieson makes a yummy effervescent vitamin C. It is a great way to get a much-needed glass of water and Vitamin C. You just drop a tablet into a glass of water and wait for it to dissolve. One tablet delivers 1000 mg of vitamin C and it is a delicious naturally flavoured orange drink. It is sweetened with stevia NO SUGAR! I really like that it is easy to throw in your bag or take with you travelling for when you need that extra boost of vitamin C.
