Like many Canadians I am Vitamin D deficient (as determined by my doctor) and tried a number of different tablets but was so happy to discover these at Shopper's Drug Mart. They are a more expensive option but I hate taking pills so these are a great way to make sure I get the extra Vit D I need. I stock up when they are on sale & they taste great so they are a little treat as well! I was having issues with my eyes and brain fog that have cleared up significantly over the past several months of taking the Vit D.
