Question 1

Why is it important to have vit d2?

Accepted Answer

It's important to not take d2! 
natural vit d3 is essential for our health ; reduces mortality, preventing cancer, heart disease, osteoporosis, autoimmune disease etc.However, vit d2 (a pharmaceutical) has been shown to actually increase mortality! it's commonly prescribed by doctors but these docs are (likely) unaware that d2 is harmful.Most adults need 5-8000 iu of d3/day.See http://bit.Ly/1hc250m.

Question 2

My vit. d2 is 21.4 ng and my d3 is 26.3 ng for a d2/d3 total of 47.7 my dr. says aok others say now way to low opinions?

Accepted Answer

Sounds ok for a typical normal person. Testing for 25-OH-VitD2 and 25-OH-VitD3, and then adding the results to get the total vitamin D level, can help the doctor check the source of the vitamin deficiency and the treatment progress. There is debate over when it would be needed to do these tests. Some doctors feel that giving people more vitamin D would avoid deficiencies and avoid doing lab tests.

Question 3

Why does dr have me on vit d2 instead of vit d3?

Accepted Answer

If you are on very high dose vit. D -m 50, 000 iu, it only comes as d2 . Otherwise you should be on vitamin d3 that is what almost all otc supplements are.

Question 4

I have vit d deficiency and was prescribed vit d2 1.25 mg (50, 000). what is the difference between v it d2 and vit d3?

Accepted Answer

If you have a choice, use the d3 rather than the d2. The d3 is a more useful form for the human body. There are very technical differences between these compounds. Note that I am not using the term 'more natural' since these compounds are often both made synthetically.

Question 5

Vit d2 is less than 4 ng/ml while d2 is 27. overall my vit d is low. does d2 matter?

Accepted Answer

Vitamin d2 (ergocalciferol) is a "prodrug" meaning it must be converted to its active form - d3 - to be beneficial. That being said, knowing your vit d3 level can be more helpful. Vitamin d3 levels in the 50 ng/ml range are considered optimal. Remember, sunlight, fatty fish, fortified foods and even shitake mushrooms can all contribute to vitamin d levels. Proper levels ensure proper immune fnxn.

Question 6

I was given vitamin d2  50, 000 units, 1.25 mg to take weekly. i took 2 in 4 days by accident. what will happen?

Accepted Answer

This is not harmful- you would need to take it daily for weeks to become toxic. But i advise you stop d2 & change to d3 (available at health food stores) 5000 units/day & tell your doctor, because recent research suggests that whereas vit d3 is very helpful, d2 may be quite dangerous!

Question 7

My doc rx vit d2 50,000 units q week for my vit d level of 12.is that an appropriate type and dose?was taking 2,000 units d3/day obviously not working

Accepted Answer

is a drop in the ocean w/ a D level of 12.  Please do what your doc says but I prefer 5K daily of D3, 10K for the first week w/such a low level.  Peace and good health.

Question 8

What is safer to take vitamin d2 or vitamin 3?

Accepted Answer

Both are safe however some people do not convert D2 to D3 , so be sure to have your vitamin D levels checked to make sure they are rising if you take D2.  Take with meals for best absorption.

Question 9

How long does it take for vitamin d2 to get in your system?

Accepted Answer

see response. I have seem many do poorly on D2, including D3 concentrations going down. 20-25% of the population do not convert D2 to D3 well. Thus would avoid in favor of D3. Read: http://ajcn.nutrition.org/content/84/4/694.full, a relevent discussion. The D- vitamins are derivatives of cholesterol. Intake & absorption are low on a low fat diet, thus avoid. Desirable D3 conc. in the 70 range.

Question 10

Taking vitamin d2 50,000 u weekly.  is there anything else (vitamin or mineral) i should be taking with it?

Accepted Answer

The best way to know if you need vitamins, minerals, etc. is to do a Micronutrient Test.  Spectracell Lab in Texas has an excellent one.  The results are given in clear language and suggest supplements or food for any deficiencies found.  Peace and good health.
