Title : High Dose Vitamin D - Are 5,000 IUs of Vitamin D Too Much?
The Vitamin D Council advises of which most healthy people can receive 5,000-10,000 IU of vitamin D3 a day without harm. yet high dose vitamin D must be accompanied by sufficient calcium in addition to magnesium...in addition to people with certain diseases should only take supplements under the supervision of a knowledgeable doctor. Vitamin D will be essential for the absorption of calcium in addition to the prevention of osteoporosis. Recent studies have shown of which of which may also boost the immune system in addition to help to prevent cancer.
Our Centeng will automatically regulate how much vitamin D of which produces coming from sunshine. Studies show of which sunbathing from the summer for about 30 minutes can result from the production of over 10,000 IU of vitamin D in addition to of which once our skin makes about 20,000 IU, the ultraviolet light begins to degrade the vitamin producing sure of which we do not "overdose" on the sun. Vitamin D expert Dr. Vieth reports of which there will be no practical difference between vitamin D acquired coming from the sun in addition to of which acquired coming from food in addition to supplements.
The Vitamin D Council reports of which doses of 5,000 IU per day coming from all sources (sun, diet in addition to supplements) are safe for most healthy people in addition to of which there are no reports of toxicity up to 10,000 IU per day. yet the Council also warns of which without calcium in addition to magnesium in sufficient quantities, vitamin D supplementation will withdraw calcium coming from the bone in addition to will allow the uptake of toxic minerals. As everyone metabolizes vitamin D differently, the best way to identify the optimal level of supplementation will be to adjust the dosage to maintain target blood levels. The Vitamin D Council recommends of which optimal health will be supported by blood levels of 50-80 ng/mL (125-200nmol/L) as identified in a 25(OH)D vitamin D blood test.
HIGH DOSE VITAMIN D FOR TREATMENT OF SEVERE DEFICIENCY
High dose vitamin D treatment will be broadly accepted from the medical community for people who are suffering coming from a severe deficiency yet are otherwise in Great health. There are two views on the best way to receive high dose vitamin D. The most common form of high dose vitamin D from the US will be a prescription form of ergocalciferal also known as vitamin D2. yet as vitamin D2 will be less potent than vitamin D3, many doctors currently recommend high dose vitamin D3 which can be purchased in a health food store or on-line.
VITAMIN D2 (50,000 IU/week)
Dr. Michael Holick of the Boston University School of Medicine recommends high dose vitamin D2 treatment for people whose 25(OH) blood levels are below 10 ng/mL (25 nmol/L). He proposes an oral dose of 50,000 IU/wk of vitamin D2 for 8 weeks followed by another blood test to check serum levels. If the levels are still inadequate, another 8-week course of 50,000 IU/week may be prescribed until blood levels reach 30 to 50 ng/mL (75-125 nmol/L). Once these target blood levels have been attained, patients prone to developing vitamin D deficiency may be encouraged to take 50,000 IU of D2 every 2 weeks to sustain their blood levels...or 1,000 IU a day of vitamin D3. He also suggests of which exposure to direct sunlight for 5-10 minutes on the arms in addition to legs between 10am-3pm during the spring, summer in addition to fall can prevent further deficiency.
Ergocalciferol will be available to U.S. doctors in prescription strength of 50,000 units from the brand names of Drisdol in addition to Calciferol. As of which will be derived coming from plants rather than animals, ergocalciferol will be considered Kosher.
VITAMIN D3 (4,000 IU/day)
Dr. Vieth (Mount Sinai Hospital in Toronto Canada) recommends of which vitamin D3 will be the preferred choice for supplementation. In 2001, a study involving 61 healthy men in addition to women resulted in healthy increases in blood levels following daily intake of 4,000 IU of vitamin D 3-without an increase in blood calcium or urinary calcium excretion. After 2-5 months, the blood levels of participants increased to a range of 28-50ng/ml (69-125 nmol/L). Dr. Vieth has proposed a rule of thumb, of which 4,000 IU of vitamin D3/day will increase 25(OH)D blood levels by 100nmol/L (40ng/ml) after 8 months of use in addition to of which any surplus vitamin D will remain from the Centeng for approximately 2 months.
Dr. Vieth recommends a daily dose of 4,000 IU/day in order to maintain blood levels above 100nmol/L. He also clarifies of which published cases of vitamin D causing elevated blood calcium (hypercalcaemia) have involved daily intake of 40,000 IU. Hypercalcaemia due to excessive vitamin D will be generally accompanied by blood concentrations greater than 88ng/ml (220 nmol/L).
Dr. Vieth also suggests of which high in addition to infrequent dosing may result in blood level fluctuations without producing sustainable improvements in blood levels. Intake of lower doses of 2,000-4,000 IU daily rather than 100,000 IU once a month are more likely to produce the desired results.
CALCITRIOL
Calcitriol will be a steroid of which will be produced after vitamin D passes through the liver in addition to kidneys. The Vitamin D Council warns against treating vitamin D deficiency with calcitriol (or its analogs) as of which poses risks of hypercalcaemia (high blood calcium) in addition to fails to replenish the Centeng's stores of vitamin D.
HIGH DOSE VITAMIN D TREATMENT GETS SILLY (500,000 IU)
Non-compliance (failure to take medications) will be common both with prescription drugs in addition to vitamins. Pharmaceutical companies in addition to researchers often seek to address This specific problem having a "one shot a year" approach to osteoporosis medication in addition to occasionally with vitamins.
In 2010, professors at the University of Melbourne reported results of a study involving 2,256 women (aged 70 years or older in addition to considered to be at high risk of fracture) who received an annual dose of 500,000IUs of D3 supplements for three to 5 years. They were surprised of which the recipients of This specific high dose vitamin D regime had 26% more fractures in addition to 15% more falls than the placebo group. Treatment of non-compliant people with mega doses of vitamin D does not seem to be the solution....as suggested by earlier research of which lower doses ingested daily produce the best results.
There are numerous diseases for which vitamin D supplements can cause elevated blood calcium in addition to possibly compromise the immune system. In these cases, supplements should only be taken under the supervision of a knowledgeable doctor.
