  For the last couple of months, I've been doubling the dosage of my Vitamin C. I'm 44-years-old and I've been taking two tablets of Vitamin C —1,000 mg each tablet— every morning and one tablet of Vitamin B —100 mg each tablet— every morning. A friend told me that it's harmful to take 2,000 mg of Vitamin C everyday because there is a risk of it causing kidney stones. How true is this and are the dosages of these vitamins I'm taking proper for my age?

In order to avoid any side effects, we advise that you follow the recommended dosage set by Health Canada for Vitamin C.
For adults, including pregnant and breastfeeding women, the minimum recommendation is 6 mg/day and a maximum dose of 2,000mg/ day of total vitamin C intake from both food and supplements (IOM 2006). Do not exceed the recommended dosage unless prescribed by your healthcare practitioner.
With all supplements, it is a good idea to divide your dosage over the course of the day. This will allow your body to absorb more of each nutrient. In order to enhance absorption and prevent indigestion, take your supplements with meals and water.
