Vitamin D 50000 Iu Once A Week – How well vitamin D works depends on the amount of other vitamins and minerals that are present in your body. The other vitamins and minerals needed to help vitamin D work well are called cofactors. Vitamin D has a number of cofactors, such as; Magnesium, Vitamin K, Zinc, Boron and Vitamin A.
Vitamin D deficiency happens when your body doesn’t get enough of the vitamin to stay healthy. vitamin D deficiency can occur when usual intake is lower than recommended levels over time, exposure to sunlight is limited, the kidneys cannot convert 25(OH)D to its active form, or absorption of vitamin D from the digestive tract is inadequate. Vitamin D-deficient diets are associated with milk allergy, lactose intolerance, ovo-vegetarianism, and veganism.
Your dosage of vitamin D will depend on your age, gender, weight, and other factors.
The Recommend Dietary Allowance (RDA) of daily vitamin D is:
600 IU for children and adults under age 70
800 IU for adults older than 70
400 IU for infants
The following doses have been studied in scientific research – For ADULTS :
For vitamin D deficiency: 50,000 IU per week for 6-12 weeks has been used. However, some patients require higher doses for longer periods of time to maintain optimal blood levels of vitamin D.
For preventing osteoporosis: 400-1000 IU/day of vitamin D in a form known as cholecalciferol has been used in older adults. Usually it is taken along with 500-1200 mg of calcium per day. Some experts recommended higher doses of 1000-2000 IU daily, and 0.43-1.0 mcg/day of calcitriol have been used for up to 36 months.
For preventing bone loss due to use of corticosteroids: 0.25-1.0 mcg/day of vitamin D in forms known as calcitriol or alfacalcidol have been used for 6-36 months. In many cases, these forms of vitamin D are used along with calcium. Also, 50-32,000 mcg/day of vitamin D in the form of calcifediol has been used for 12 months. Finally, 1750-50,000 IU of vitamin D has been taken in daily or weekly doses for 6-12 months.
For preventing cancer: 1400-1500 mg/day of calcium plus 1100 IU/day of vitamin D in a form known as cholecalciferol has been used for up to 7 years.
