This fat-soluble vitamin is highly necessary for the way that the body metabolizes calcium, but can also be integral for mood stabilization, as it affects hormonal release through its effect on the parathyroid. Although Vitamin D is available in gelatin capsules, it is also commonly taken by the dropper, since this allows for easier absorption through the intestinal walls. Vitamin D is found in many fish oils, although it may also be clarified or synthesized for easier ingestion.
Vitamin D is actually manufactured by the body, although exposure to sunlight is necessary for this to happen. Many people do not produce the necessary amounts of Vitamin D, due to lifestyle habits, and this can lead deficiency issues which manifest in the bones and teeth, but also as mood problems such as depression and Seasonal Affective Disorder.
Daily requirements for Vitamin D are around 400 IUs daily, although this can greatly vary depending upon an individual’s sun exposure. Since Vitamin D is stored in the fat cells, toxicity can be a concern due to buildup in the tissue, especially if higher therapeutic doses are taken. However, the RDA is considered quite safe, and deficiency problems can create greater concerns.
Individuals who have issues with calcification may be candidates for therapeutic dosages of Vitamin D. People with mood disorders also do well on this supplement, as it is necessary for triggering hormonal responses, but also for supporting the development of the myelin sheaths on nerves. As a result, Vitamin D has been used effectively in problems with nerve pain and some neurological issues, although this is as an adjunct to other therapy.
Although there are food sources for Vitamin D, it is most frequently taken as a supplement in order to gain the concentrated dosage that is required. While the body will produce Vitamin D with sufficient sun exposure, this is not always enough to aid in healthy bone formation and hormonal regulation.
