Dosages, bone density
Regarding your June 13 article “Panel: Calcium, Vitamin D don’t prevent fracturesâ€: Unfortunately in many supplement and vitamin studies patients are under-dosed or the necessary combination of vitamins and minerals are neglected. Standard osteoporosis trials rarely use magnesium but focus exclusively on calcium. Magnesium is an important mineral for bone metabolism, so calcium alone may not be effective.
One researcher found that bone density increased up to 8 percent annually with calcium-magnesium in combination, whereas untreated controls lost bone density an average of 1 percent annually. In another study nearly 65 percent of postmenopausal osteoporotic women who received magnesium at levels ranging from 1,500 to 3,000 mg of magnesium lactate per day for two years were classified totally free of pain and with no further vertebrae deformity.
Another study showed that using 4,000 IU per day of Vitamin D was effective. However the National Academy of Sciences recommendation is only 2,000 IU/day. The correct dosage is essential. Patients should consult practitioners who are knowledgeable about supplements.
