With the ‘flu season’ among us, it’s very important to discuss one of my favorite health topics: Vitamin D. Three components are covered in this video: (1) Why is vitamin D important? (2) How much do you need? (3) Resources

(1) Why is vitamin D important? Vitamin D is vital to the immune system and its production in the human body is initiated when UVB sunlight makes contact with the skin. The so called ‘flu season’ is actually ‘less sunlight season’. Vitamin is a critical component for the body to produce antimicrobial peptides which are a major immediate defense mechanism of the innate immune system. So in essence, no lower sunlight exposure mean, lower vitamin D, and finally lower antimicrobial peptide product. This results in a weaker immune system during the critical winter months.

(2) How much do you need? There is no simple answer to this question. Each person will have their unique need. The first important step to do is to have a blood test performed to assess your current vitamin D levels. The next step is discuss with your doctor what your results mean and how much you may or may not need to take through supplements or diet. The traditional scale ranges between 30 – 100ng/mL (nanograms per millileter). More naturopathic ranges are between 40 and 60 ng/mL or 50 – 80 nb/mL. A vast majority of people are deficient (have less than 30 ng/mL). Vitamin D is typically packaged in dosages referred to as International Units (IU). On average for every 1000 IU’s the vitamin D blood levels may be raised about 10ng/mL. There are many factors that effect overall vitamin D levels that will need to be disgust with your doctor.
