My whole family (two adults and two children aged 8 and 11) take this vitamin C throughout the winter months. It is a very reasonable price and extremely pure. I tend to choose our vitamins based on the quality and number of ingredients - this product has proved itself a winner again and again. The Finchley clinic never disappoints when it comes to reliability, both in terms of delivery (prompt) and product quality. I recommend them unreservedly to my friends and family.
