 Is Vitamin D the Nutrient of the Decade? You Decide!
Text: Is Vitamin D the Nutrient of the Decade? You Decide! Ask Dr. Tim Doctor of Chiropractic – Registered Nutritional Consultant Practitioner In January 2011, the Irish Medical Times discussed a re-emergence of rickets, and that possibly over 50% of apparently healthy Irish adults have vi- tamin D insufficiency.

Vitamin D is naturally produced in the human body by interaction of the sun's UVB rays with cholesterol in the skin.

In Ireland from October to March, very little vitamin D is produced because al- most no UVB is available.

Some of the greatest proven benefits of maintaining optimal levels of vitamin D are a reduced risk of: cardiovascular disease, diabetes, depression, infectious diseases, dental cavities, autoimmune diseases such as multiple sclerosis, and certain cancers such as breast, colon, ovarian and prostate. Even athletic per- formance can be improved.

A 2011 peer-reviewed study done in the journal Anticancer Research, found that an intake of 1,100 to 4,000 IU of vitamin D daily and a blood serum concentration of 25-hydroxyvitamin D in the range of 60 – 80 ng/ml (150 – 200 nmol/L) is re- quired to reduce cancer risk. This same study showed that intakes as high as 40,000 IU daily are unlikely to result in vitamin D toxicity, and that no daily supplemental levels of 10,000 IU or less produced toxicity.

Ask your family doctor for a blood serum 25-hydroxyvitamin D test, and have levels monitored regularly – per- haps two or three times a year, especial- ly in the late fall, winter and early spring when sunshine is weakest. What are the optimal vitamin D serum levels? This is debated, but suffice it to say that most peer-reviewed research today shows that a serum level in the range of 50 – 80 ng/ml (125 – 200 nmol/L) provides the strongest benefits. See vitaminD, and VitaminD-

The best sources of vitamin D are sun- light (10-minutes of daily skin exposure a few days of the week), wild-caughtfatty fish like salmon, mackerel, and sar-dines, and UVB-exposed mushrooms.

If you choose to add a vitamin D sup-plement, be careful that it is not in a baseof omega-6 oils, nor containing artificialsweeteners such as aspartame.
