Materials and methods:Between June 2016 and May 2017, 48 patients with baseline total 25-hydroxyvitamin D less than 30.0ng/mL were randomly assigned to either group one (one dose of 100,000 international units (IU) of Vitamin D2) or group 2 (100,000IU of Vitamin D2 once weekly for ...
infections in individuals 0 to 95 years of age, age-appropriate daily or weekly vitamin D3supplementation without additional bolus doses was suggested to protect against acute respiratory infections, particularly in those with low baseline 25-hydroxyvitamin D (25[OH]D) levels (less than 25 nmol/...
Although D2 and D3 differ by a single carbon atom, there is evidence that D3 is more efficiently utilized in chicks (4) and, more to the point, in humans. "The assumption that vitamins D2 and D3 have equal nutritional value is probably wrong and should be reconsidered." (5) There ...
An initial supplementation for 8 weeks with vitamin D3 at either 6000 IU daily (10,000 IU for high-risk adults, 2000 IU for children) or 50,000 IU weekly is usually administered. And then, a daily maintenance dose of 1000 (for children) to 2000 IU is recommended (3000 to 6000 IU ...
Here, a vitamin D level below 30 ng/ml was considered insufficient. All participants in the study were prediabetic. The treatment group received a once-weekly dose of 60,000 IUs of vitamin D3, along with 1,250 milligrams (mg) of calcium carbonate daily, for eight weeks. A second group...
Vitamin D deficiency may impair muscle strength recovery after ACLR. Correcting vitamin D levels may improve muscle strength. Methods This is a double-blinded, randomized controlled trial to investigate the effects of vitamin D supplementation during the post-operative period on quadriceps muscle ...
Furthermore vitamin D can be taken daily or the total amount can be taken once a week or even once a month as long as the total is the same i.e., 3000 IUs daily or 21 000 IUs weekly or 90 000 IUs monthly are equally effective in maintaining serum 25(OH)D levels in the ...
Treatment of existing prostate cancers with vitamin D also shows promise. In a 2006 Phase II clinical trial,62researchers administered calcitriol three times weekly (at up to 12 mcg [480 IU] per dose) with the potent steroid dexamethasone. Thirty-seven men with androgen-independent prostate cancer...
Once vitamin D enters the circulation, it is weakly bound to the vitamin D binding protein for transport and is stored in adipose tissue. It is metabolized by 25-hydroxylase (CYP2R1) in the liver to 25-hydroxyvitamin D [25(OH)D], which is then converted by the 25-hydroxyvitamin D-1α...
