Vitamin D Debates



If you are female, over 50 and overweight you are most at risk of a Vitamin D deficiency. But according to research at Boston University, everyone living in northern climates is at risk during the winter. This is the time when we have very little sun exposure which means that our body cannot make its own Vitamin D. Long term deficiency of Vitamin D is related to increased risk of osteoporosis, multiple sclerosis, cancer, diabetes, inflammatory bowel disease and rheumatoid arthritis. There is also increased susceptibility to viral infections during winter.


Large scale studies found that Vitamin D levels in the body are reduced by 50% less during the winter. This makes it imperative to increase our intake at this time of year. The best form is D3 the same form that is created when our skin is exposed to the sun. Cod liver oil is one of the best sources of D3; sardines, salmon and herring are almost as good. Unfortunately, many supplements contain Vitamin D2, a synthetic source which the body does not absorb as well. Foods fortified with Vitamin D, like milk, will contain the synthetic D2. Since we can receive some Vitamin D from food, there is debate about how much we need by supplement. The answer is not simple because needs vary from person to person ranging from 400 IU to 1000 IU daily. In recent years these estimates have been increased to 2,000 to 8,000 IU daily, with the higher dosage reserved for those with ongoing health problems.


The question of whether YOU need more Vitamin D can be addressed in a Holistic Nutrition Consultation from Health E Guide. This consultation includes three assessment tools: 1. Analysis of symptoms or health issues that are related to Vitamin D intake; 2. Analysis of your diet for actual nutrient levels; 3. A Bio Energetic Evaluation to determine if you would benefit from a Vitamin D supplement.
