Vitamin D 1000 IU-90 tabs

Quest Vitamin D 1000

Vitamin D is a fat-soluble vitamin that plays a dual role as both a vitamin and a hormone. Vitamin D is a great regulator of calcium and phosphorus metabolism. Without vitamin D, the body cannot properly absorb calcium and the bones and teeth become soft and poorly mineralized.

The efficacy of vitamin D supplementation is borne out by scientific research. In a recent study, 198 children were followed to determine the effect of vitamin D supplementation by their mother during pregnancy. The researchers found that children whose mothers took vitamin D has significanly larger bones and a higher bone-mineral content in their bodies than children who mothers did not take the vitamin. In addition, several studies indicate that adequate vitamin D intake may offer protection against cancer of the breast, prostate, colon and overies.

Quest Vitamin D Cautions

No side effects expected at recommended dosage. Excess vitamin D (more than 50,000 IU per day) can increase blood levels of calcium, leading to weight loss, nausea, and damage to the heart and kidneys. Too much vitamin D can also cause a weakening of the bones and deposition of calcium in the soft tissues (i.e. muscles). Excess vitamin D can also cause diarrhea or constipation, headache, appetitie loss, nausea, vomiting, extreme fatigue, and heartbeat irregularities.

Do not use if you are taking anticoagulant drugs, calcium channel blockers, or magnesium-containing antacids.
