* Science + Therapeutic Potency = Results * Since 1972 * Dietary Supplement * The Wright Formula For Bone Health * 3rd Party Confirmed GMP Compliant Osteo-Mins PM with D was developed and formulated by Jonathan V. Wright M.D., author of Nutrition & Healing. This product is recommended and used at his Tahoma Clinic and Dispensary in Renton, Washington. Bioavailable calcium is essential for bone health; however, bone is complex living tissue that, like other body tissues, has a wide range of nutritional needs. The Osteo-Mins formulas were developed and formulated by Jonathan V. Wright, M.D., author of Nutrition and Healing. In addition to calcium these formulas supply strontium, boron, silicon and other vitamins and trace minerals proven by research to support bone growth. The Osteo-Mins AM formula containing strontium, zinc, selenium, copper, manganese, molybdenum, boron and silicon is taken in the morning. The Osteo-Mins PM formula containing calcium, magnesium, vitamin D (or vitamins D and K) are taken at bedtime. Many researchers feel when these nutrients are taken at different times during the day, assimilation of all nutrients is improved.
