Vitamin D is more effective than calcium for protecting and building bone, plus it powerfully protects against cancer. Too much calcium can actually interfere with the conversion of vitamin D into its biologically active form, but some extra calcium taken with the Vitamin D has been shown in studies to aid bone health. The main issue is that most people still take too much calcium and do not have adequate levels of vitamin D in their tissues and this places them at a dramatic increased risk of osteoporosis and other diseases. A multivitamin containing the RDA for D is simply not sufficient to bring blood levels up to the ideal range, especially as we age.
My recommended dosage of Vitamin D varies based on individual need, but my supplement Osteo-Sun is designed so most people will be in the ideal range from the intake of 3 per day, in addition to one's multivitamin. Some may require more and some may not need as much as 3, however, the amount that is right for you can best be determined by a blood test screening for vitamin D 25 hydroxy. Most people, over 80 percent, taking a typical multivitamin that contains 400 IUs of vitamin D are still deficient when tested.
I recommend that people take 2 of my Gentle Care Formula daily supplement, with 800 IUs of vitamin D, plus 3 of the Osteo-Sun. Then at some point, just to make sure the standard recommendation is right for you, have your vitamin D levels checked with a blood test. Then the supplement dose can be adjusted up or down depending on the results. Take one extra if your level is below 35 and take one less if your level is above 50.
My vitamin D supplement is designed to have most people fall in this ideal range, not too much and not too little. For those getting more daily sun exposure, generally, taking only 2 daily is adequate. Plus, it has silica for stronger bones, hair and nails! Osteo-Sun gives you the extra vitamin D you need and just the right levels of calcium and magnesium to maximize bone health. It comes in two formulas:
Osteo-Sun: Contains vitamin D3, or cholecalciferol, derived from sheep wool and is the most potent and efficient form of vitamin D.
Osteo-Sun Vegan: Utilizes vitamin D2, or ergocalciferol, a form of the vitamin which is obtained only from plant sources. Higher levels of vitamin D2 are used in this product to adjust for its lower hormonal activity. Even though it may have a shorter half life, in daily use, this higher dose, taken regularly, is just as effective.
