Vitamin D - in Puritans Pride CalMag citrate with Vitamin D.
The Mayo Clinic states on their web site: Vitamin D is included in most multivitamins, usually in strengths from 50 IU to 1,000 IU as softgels, capsules, tablets, and liquids.
The Adequate Intake (AI) levels have been established by the U.S. Institute of Medicine of the National Academy of Sciences. Recommendations are: 5 micrograms (200 IU or International Units) daily for all individuals (males, female, pregnant/lactating women) under the age of 50 years-old. For all individuals from 50-70 years-old, 10 micrograms daily (400 IU) is recommended. For those who are over 70 years-old, 15 micrograms daily (600 IU) is suggested. Some authors have questioned whether the current recommended adequate levels are sufficient to meet physiological needs, particularly for individuals deprived of regular sun exposure. The upper limit (UL) for vitamin D has been recommended as 2,000 IU daily due to toxicities that can occur when taken in higher doses.
Not all doses have been found effective for conditions that have been studied. However, ergocalciferol has been used in an oral dose of 400 to 800 IU per day (sometimes higher doses are used in conjunction with calcium) for osteoporosis prevention and treatment.
Calcitriol has been used in an initial oral dose of 0.25 micrograms per day; dosing may be increased by 0.25 micrograms per day at four to eight week intervals in patients with hypocalcemia from chronic dialysis.
Dihydrotachysterol has been used in an oral initial dose of 750 micrograms (0.75 milligrams) to 2.5 milligrams per day for several days for the treatment of hypoparathroidism. A maintenance dose is typically 200 micrograms (0.2 milligrams) to 1 milligram per day. Ergocalciferol has also been used in an oral dose of 50,000 to 200,000 IU units daily concomitantly with calcium lactate 4 grams, six times per day." End of Mayo Clinic information.
Since Puritan's Pride CalMag Citrate with Vitamin Doffers 25 IU per capsule, taking the recommended 4 capsules a day will give you 100 IU. Since the recommended dosages for those over age 50 is between 400 - 600 IU and recent recommendationsfor those with Osteoporosis and Osteopenia are even higher, Puritans Pride CalMag Citrate with Vitamin D will NOT supply enough Vitamin D in the recommended dosage.
