This months question:
- Dietary Supplement Mania. Should we worry about mega-dosing fat soluble vitamins or water soluble vitamins or all of them? Why?
Dr Cathy’s reply:
Fat soluble antioxidant vitamins can accumulate in the body over time and cause unwanted side effects. For example, vitamin E in doses higher than 200 IU daily for more than two years can increase risk of stroke and other cardiovascular disease. Vitamin A intake higher than 1250 IU daily (supplement or juicing) increases risk of hip fracture in both men and women. Water soluble vitamins have their issues in high doses, too. Vitamin C may actually be pro-oxidative in doses higher than 500 mg – 1,000 mg daily. It can cause kidney stones, increased risk of bruising and bleeding as well. The body does not absorb more than 250 mg daily.
All three of these supplements are excellent antioxidants but it’s still better to eat colourful fruits and vegetables from the Mediterranean Diet than to supplement since there are literally thousands of antioxidants in nature from which to choose. The body craves variety.
Be sure you talk with your doctor or pharmacist about the best vitamin supplements for your individual health needs and goals.
