What will this vitamin do for me?
Vitamin D is essential for health and well-being. It plays a critical role in regulating calcium and phosphorus levels in the body, and is important for healthy bones and preventing abnormal cell changes, which may increase the risk of some cancers. Optimal levels of vitamin D appear to be associated with reduced risk of death, especially in the elderly.
When will it start to work?
This will depend on the condition being treated. In uncomplicated patients, serum levels should begin to rise in one to two days and after three weeks signs of calcium and phosphorus mineralization appear in X-rays. For disease prevention, long term adequate vitamin D status is recommended. Sometimes it can take up to 6 months for vitamin D levels to become normal! The recommended dosage for most people with low vitamin D that are otherwise healthy is 1,000 I.U., taken twice daily.
Are there any safety issues?
Vitamin D is considered to be a safe supplement when used in the recommended doses: however, it may interact with some medicines.
