“These are the most common nutritional deficiencies I see in my Orange, chiropractic and integrative medicine practice: Magnesium, Zinc, Vitamin D, Vitamin E, Omega 3 Fatty Acids (ALA, EPA, DHA) and Iodine (potassium Iodide). I personally feel that these deficiencies are not just representative of my local area but are a glimpse of what the world, in general, is experiencing. Below is a brief summary for each nutrient. I have come to this conclusion based on dietary analysis, clinical observation/correlation, blood and urine tests.” Marcus Ettinger BSc, DC

Recommended Nutritional Supplements: BEST VITAMIN D3 (cholecalciferol) PRODUCT: Liquid Vitamin D Forte by Biotics Research ($20  for 700+ drops. Each drop = 2,000 IU’s). Recommended dosage of emulsified Vitamin D3 (cholecalciferol) –  (6,000 – 10,000 IU’s per day for adults and 2,000 IU’s for children above the age of five).  Skin exposure to the sun, 15 minutes per day, is another great way to get adequate Vitamin D exposure.  Note: living in southern California, I only take my Vitamin D3 during the months of October through the beginning of June. I surf a lot, and as soon as my wetsuit comes off and I can get 15 minutes+ of direct sunlight, I no longer need the supplement form. In fact, if I kept taking it, I would sunburn within 15 minutes. This is what your body does when the vitamin D3 level is maxed-out.
