Vitamin D (D2) Ergocalciferol (D3) Cholecalciferol

What is Vitamin D?

Vitamin D is a fat-soluble vitamin which can also occur as D2 (Ergocalciferol) and D3 (Cholecalciferol). Of these, Vitamin D2 is the most common form added to foods and milk. It is not as active as D3. Vitamin D3 is formed in the skin when exposed to ultraviolet sunlight. When formed it is transported, by a transport protein, to the liver and converted into 1, 25-dihydroxyvitamin D3: the most biologically active form of vitamin D. The conversion can occur in other organs and tissues including the kidneys, prostate, bone and white blood cells. Some prominent researchers have identified Vitamin D deficiencies as pandemic. Deficiencies are associated within individuals who have little sunlight exposure, or who have digestive issues with poor absorption or kidney disorders.

Why is Vitamin D important and what does it do in the body?

Vitamin D is a fat-soluble vitamin that plays a role in many important body functions. It is best known for working with calcium to help build and maintain strong bones. Vitamin D is also involved in regulating the immune system, reducing the risk of autoimmune responses such as insulin-dependent diabetes and multiple sclerosis and it may help prevent cancer. A lack of vitamin D3 in mothers during pregnancy has also been associated with the development of autism and developmental disorders.


What amount of Vitamin D do you need each day?

Vitamin D comes in a number of different forms and you have to choose your supplement carefully. The most bio available source is 1, 25-dihydroxyvitamin D3. Requirements are different for each individual but an intake of 700 - 1,000 ius/day has been shown to increase serum D3. Intakes for younger adults may be higher, ranging from 4,000 - 10,000 ius/day.

The DRI (Daily Recommended Intake) /RDA (Recommended DailyAllowance) of dietary vitamin D are listed below:

Please Note: By definition, the DRI/RDA recommendations apply only to 98% of healthy individuals and are not sufficient for those with higher nutrient requirements based upon their biochemical individuality, genetics, health status, medications, deficiencies, lifestyle, and toxic exposures.

Recommended dietary allowances for vitamin D are listed below.

The National Institutes of Health has set the maximum tolerable upper limit at 1,000 IU daily for infants 0 - 6 months, 1,500 IU daily for infants 6 months to one year, 2,500 IU daily for children 1 - 3 years, 3,000 IU daily for children 4 - 8 years, and 4,000 IU daily for anyone over 9.

Pediatric

Ask your doctor before giving a vitamin D supplement to a child.

  • Infants birth to 12 months: 400 IU (adequate intake)
  • Children 1 -18 years: 600 IU (recommended dietary allowance)

Note: The American Academy of Pediatrics (AAP) recommends 400 IU of vitamin D daily for breastfed infants until they are weaned and drinking at least 1 liter per day of whole milk, or formula fortified with vitamin D. The AAP also recommends that children and teens, who drink less than 1 liter of milk a day, take 400 IU of vitamin D.

Adult

  • 19 - 50 years: 600 IU (recommended dietary allowance)
  • 70 years and older: 800 IU (recommended dietary allowance)
  • Pregnant and breastfeeding females: 600 IU (recommended dietary allowance)

Recommended Daily Intake 5mcg/Day

Optimal daily Allowance 30mcg/Day

What are possible Vitamin D excess symptoms?


Dosages of Vitamin D are poorly understood regarding toxicity. You cannot get too much vitamin D from sunlight, and it would be hard to get too much from food. Generally, excess vitamin D is a consequence of taking in too high a dose as a supplement.

Excess vitamin D can cause several side effects including:

  • Extreme thirst
  • Metal taste in mouth
  • Poor appetite
  • Weight loss
  • Bone pain
  • Tiredness
  • Sore eyes
  • Itchy skin
  • Vomiting
  • Diarrhea
  • Constipation
  • A frequency of urination
  • Muscle problems

Individuals with the following conditions should be especially careful in taking vitamin D supplements:

  • High blood calcium or phosphorus levels
  • Heart problems
  • Kidney disease
  • Sarcoidosis
  • Tuberculosis


What steals Vitamin D from the body?

A lack of sunlight - prevents Vitamin D3 synthesis.

Anti-Hyperlipidemiadrugs (bile acid sequestrants): Cholestyramine (Questran) and Colestipol (Colestid).

Antiseizure medications: Phenytoin (Dilantin), Carbazamine (Tegretol) and Primidone (Mysoline)

Corticosteroids: Prednisone(Meticorten), Dexamethasone (Decadron), Methylprednisolone (Medrol)

Goutmedications: Colchicine (Colbenemid), Probenecid (Benemid)

Antifungalmedication: Ketoconazole(Nizoral)

H-2 Receptor Antagonists: Cimetidine (Tagamet), Famotidine (Pepcid), Nizatidine(Axid), Ranitidine (Zantac).

Weight management drugs: Orlistat (Xenical) as it decreases exocrine output and reduces fat absorption.

Mineral oil - interferes with absorption of vitamin D.

Additional drug/vitamin D interactions;

Atorvastatin(Lipitor)- vitamin D may reduce the amount of Lipitor absorbed, making it less effective.

Calcipotriene (Dovonex) - vitamin D supplements could cause calcium levels to increase in the blood.

Calcium channel blockers- vitamin D may interfere with: Nifedipine (Procardia), Verapamil (Calan), Nicardipine(Cardene), DiltiaZem (Cardizem, Dilacor) Amlodipine (Norvasc)

Corticosteroids- long-term corticosteroids can cause bone loss and osteoporosis and may require additional Vitamin D3 and Calcium.

Digoxin(Lanoxin) -vitamin D may cause levels of calcium to increase in the blood.

What tests can be used to assess Vitamin D levels?

Blood levels Vitamin D as 25-Hydroxyvitamin in serum 250nmol/L is indicated as toxic.
