In discussions elsewhere, the two terms seem to be used almost interchangeably.
 
I would like to just get a small amount of a supplement (1000 IU) without doing the blood test. (My doctor suggested I do it without bothering to get the test) Should I get D or D-3?

"Vitamin D without a subscript refers to either D2 or D3 or both."

 Vitiman D is found in milk and other foods and is not absorbed into the body very well. D3 is what is found in your skin which is made by sunlight and is absorbed  than the more  easily. D3 is what you want. How much depends on your location and skin type. If you have a darker complexion the more D3 you need. I have herdf up to 40,000 IU per day.

D2 is ergocalciferol, a plant based form. This is not the form which is metabolized in the human body to affect bones, general health, etc. You (we) want cholecalciferol, or D3

Wow. Someone said 40000IU of D-3.

My doctor just suggested 1000 IU of D.

 

I'm thinking of doing 1000 units of D-3.

Are the IU of D and D-3 comparable?

 

Or does 1000 IU of D translate to a higher IU number for D-3.

 

Thanks,

Mel

Mel I know I am weird (LOL) but my example of using 6000 units of D3 and achieving a level of 60 ng/ml the average area they mention is useful for us types of patients.
Was a clue, I doubt you are than much different, but you can test for this with OH25 test.

The "Vitamin" in Vitamin D-3 is a misnomer. It's actually a pre, or prohomone that is essential to the whole hormonal system. Most of us are either deficient, or sub-optimal, and need to bomb the system with D-3 supplements to get into the optimal range. So whether you see me taking 50K pill per week, or other guys taking 5000-6000 per day, it's all in an effort to jump start things. Not meant to stay at that intake level once circulating level is achieved.
 
Google some version of D-3, plug in testosterone, etc., and you'll be amazed at how important this is............of course, 95% of us here are post-treatment, but it's protective benefits in warding off cancer are well documented as well.
 
Mel, I too think it would be beneficial for you to establish a baseline of D-3 before you take anything. If it's really low, you could be pissing in the wind like I was with 1000 IU perday after having a starting level of 25. Then, whatever approach you decide on, you can monitor so it gets high enough, but not too high that it would become detrimental.

<<Dr Myer recommends D3, but don't ask me why>>

Dr. "Snuffy" Myers, in his book "Beating Prostate Cancer: Hormonal Therapy & Diet", states:

(Quote) We live in an age when obesity and the diabetes that follows are increasing at stunning rates. Vitamin D Deficiency exacerbates both. Lack of adequate Vitamin D also increases the risk of hypertension. In turn, high blood pressure, diabetes, and obesity foster the development of heart disease; inadequate vitamin D levels increase the risk of heart attack and congestive heart failure (End Quote)

Dr. Myers goes on to say that he recommends 4000 - 5000 IU daily even though the commonly recommended daily allowance is only 400 (multi-vitamin). Further, he recommends D levels be checked concurrent with other lipid panel reviews such as PSA, dihydrotestorone, etc. every 3 months. Reviews in the 50-100 ng/ml range are the broad 25-hydroxy Vitamin D goals.

Without doing a blood test why bother taking anything

Like I said before if you had a blood test and knew your level were 22 taking 1k of D3 may get you to 25 and that does nothing for you, so you are still way short. BUT say your blood test shows 95 then taking 1k gets you over 100 and causes a toxicity problem, then you need blood tests and figure out a way to lower it

Blood test is free, like the Nike add says " Just Do It"

What peace of mind does taking 1k of D3 offer you if you do not know if it is working

The generic Vitamin D - labeled pill I'm taking refers to it being D3 Cholecalciferol 1,000 IU; 250% of the recommended daily value when you look at the facts label. My doctor said it wouldn't hurt (1 a day), but will add the level test for next checkup.
 
Mr. Gimpy - my insurance (still employed, <65) makes me pay for blood work, so when I get the next round of tests I'll have a $ number for you cry .
