Vitamin D FAQ :)
The sunshine vitamin is good stuff :tu
since we often have same questions about supplementing and natural production, I'm starting this thread :sillygrin 1. Production of Vitamin D--getting out in the sun :sun --UVB rays cause vit. D production. Melanin will filter UVB. the darker the skin, the more time a person has to spend in the sun to produce necessary vit. D. --This is a very nifty handy calculator that will tell you how long to stay outside, while accounting for skin color, time of day, geographical position, etc. This is an article that will help with use of the calculator. --Antioxidant-rich diet will offer natural protection to your skin. Eat well and hang out with no sunblock for some time ;) --If your skin turns a very very slight shade of pink, you can assume you have made all the vitamin D you will for that day. It will now take you up to 48 hrs to absorb it into the bloodstream. Avoid scrubbing, rubbing, soaping, and exfoliating. 2. What's vitamin D good for: :question Currently we have scientific data to show that vit. D plays an important part in preventing and/or treating -chronic pain -cancer (breast, ovarian, colon, rectal, pancreatic and other) -cardiovascular disease -premature births -insufficient strength/endurance of the uterus -weak immune system -psoriasis -osteoporosis -diabetes -high blood pressure -MS -postmenopausal weight gain -tooth health -mental health -overall mortality reduction :phew convinced yet? 3. What are the food sources of vitamin D? :brownies :lol Cod liver oil is a natural source, highest in vit. D. other fatty fish, liver and egg yolk also contain it. here is a table :) 4. Supplementing :chill Tolerable upper intake levels (this is the highest level of intake considered safe for daily use, without risking toxicity or other adverse events) for vitamin D have been revised and are not being revised again b/c of studies being done. afaik, latest data is this: Birth--1 yr old=25 micrograms (or 1,000 IU) 1 yr and up=50 micrograms (or 2,000 IU) these numbers are produced by the same guys that come up with RDA's commonly referenced on the nutrition panel of our food packages, and in my opinion, they tend to be conservative. Alternative medical advice: Adults over 100 lbs--10,000 IU daily Breastfeeding mothers--10,000 IU daily (emphasis mine :giggle) Children over 2 yrs old and under 100 lbs--5,000 IU daily HomeFirst flu/cold treatment: 1,000 IU per 1 lb for 7 days. (so, if you weigh 150 lbs, that's 150,000 IU for 7 days) if you are scared by numbers, remember that a dressed caucasian adult will make 10,000 IU in 30 min of being outside, even without being in direct sunlight. D2 (ergocalciferol) vs D3 (cholecalciferol) Whenever I talk about vitamin D, what i mean is vit D3 :yes This is what gets formed when the sunlight comes in contact with your skin. D2 is made by stuff like mushrooms and slugs under the sunlight :yuck :giggle While today western medical community recognizes both D3 and D2 as appropriate for supplementation and use them interchangeably, alternative practitioners avoid vitD2 because: -it is not found in human body except when consumed with, say, mushrooms, and even then in *tiny* amounts -tends to be more toxic -while little is known, there may be some metabolic issues :shrug3 Bottom line is, supplementation with D3 is a lot more desirable, b/c it is the natural form made in the human body. 4. Testing for blood levels when getting blood work, the test needed is called: 25(OH)D3 aka 25D3 aka calcidiol aka 25-hydroxyvitamin D :phew try saying that really fast five times. those are all the same thing, just different ways to say it. How to interpret the results: western medicine 0-20 ng/ml -- deficient 30-60 ng/ml -- preferred over 150 ng/ml -- toxicity alternative medicine under 50 -- deficient 50-80 -- preferred over 150 --toxicity If you are supplementing for significant health concerns, or have a history of one of the disorders mentioned above, it is recommended that you do test. Some people required much higher doses and continued testing to stay within healthy range. http://www.informationisbeautiful.net/2010/vitamin-d/ cute graphic |

Re: Vitamin D FAQ :)
ok, i'm done editing for now. let me know if there is any other info you'd like to see, have any further questions, etc. :)

Re: Vitamin D FAQ :)
Are there any brand/supplement suggestions? Michigan is awful for sunlight in the winter. I don't remember us having a single day of sunshine in Februray. I think supplementing would help me out a lot.
I was totally going to make a thread asking this too! i'm so glad it was already here! |
Re: Vitamin D FAQ :)
Very nice, Irene :)
When DD2 was Vit D deficient w/ asymetrical bowing of her legs @ 10 mons (she was a VERY early walker), the endocrinologist had us put her on 2000iu per day supplement for 2 mons. That was 5x the recommended dosage for her age/size. I thought 400iu was the recommendation for kids? ---------- Post added at 01:44 PM ---------- Previous post was at 01:43 PM ---------- Quote:

Re: Vitamin D FAQ :)
:ty
I can take 10,000iu easily when I have the 5,000iu capsules but do you think I should take more than that, Irene? (I have MS.) Also, I make my ds take it because of the mother/son MS potential. How much should he take? He takes 4,000iu atm. He is not very heavy yet, just tall. LOL. Thanks! |
Re: Vitamin D FAQ :)
If you are concerned about vitamin D levels please have them checked--if possible, by an endocrinologist or someone who can get you to one as soon as your levels are low. Too low can be critical. And menopause is NOT the primary sign for checking for parathyroid levels or osteopoenia.
I do not make vitamin D hardly at all. I have to be on extremely high supplemented levels under doctor supervision (100,000 iu's a week). I had hyperparathyroid and osteopoenia at 37 :( I have not gone through menopause. There is also a difference between D2 and D3 but I can't find a lot about it. |
Re: Vitamin D FAQ :)
Crystal, :hug i considered getting into all the parathyroid and osteopoenia issues, but figured it'd be a little to hairy for FAQ totally valid points though :yes and again, i totally agree that you will have a really extra fancy heavenly body :angel (off to add info on D3 vs D2)
Ruth, b/c of the MS, i would really look into getting tested. :) What you and your son are taking right now is good, yes. However, you may require a little or a lot more, or perhaps you are exactly where you need to be. One way or another, it'd be very valuable info to have b/c good vit. D levels are essential with this condition. (off to add info on testing) |
Re: Vitamin D FAQ :)
Supplemental vitamin D needs to be an oil-based D3, *not* D2 and not in dry tablet form. Carlson Ddrops is a good brand (it raised my kids' and my levels well, verified by blood tests; I have no vested interest in them other than being a very satisfied customer :giggle).
Blood test for level should be the 25-hydroxy vitamin D. (Double-check the name of the test; there is another test called the 1,25 dihydroxy which is *not* good for assessing whether your vitamin D level is adequate.) On the amount to supplement, medical literature shows that 10,000 IU/day is generally safe for adults. HOWEVER, as a breastfeeding mother up north, over a number of months 10,000 IU/day raised my blood levels to 141, which is too high. Right around 70-80 is probably the safest ideal blood level, based on current knowledge. Blood levels should not be lower than 50, or your body is most likely chronically starved for vitamin D and not storing any (conventional labs are behind and still consider as low as 30 to be ok--it's not). The Vitamin D Council currently recommends: -children under 1: 1000 IU/day (note: I disagree with this IF baby is breastfed AND the breastfeeding mother's levels are adequate/supplemented. I did not supplement my son directly until he was 2, and he had adequate blood levels from my milk and the sun. My own blood levels were adequate with supplementation.) -children over 1: 1000IU/day per 25 lbs body weight -adults: 5000 IU/day All to be followed by a blood test a few months later. It really is important to get your blood levels checked (and continue to do so at least twice a year) because everyone metabolizes vitamin D differently, as Crystal said. Factors which tend to reduce metabolization of vitamin D include obesity, age, and taking statins. http://www.vitamindcouncil.org/healt...eficient.shtml |
Re: Vitamin D FAQ :)
What do you know about the controversy about the accuracy of Vit D3 tests? I just read an article about that here and it gives me pause about trusting the test results to be accurate and whether it's even worth doing:

Re: Vitamin D FAQ :)
That's the first I've heard of that issue. :-/ It makes me want to :hissyfit Thanks for the info.
Anecdotally, the first test I did was from ZRT; the next two were from my doctor's office. The results made sense (good level; high level; high level but significantly better--I'd stopped supplementing between the 2nd and 3rd tests). Beyond that, :shrug |
Re: Vitamin D FAQ :)
each lab, even those standardized, has their own levels they use for everything. The key is to look at their range and where you fall in that.
and I didn't think it would be good to put everything in the OP, but I wanted to mention it in the discussion so that it would be out there and those who wanted more info could start searching or asking :yes ---------- Post added at 03:00 PM ---------- Previous post was at 03:00 PM ---------- also, is all oil based vitamin D D3? |
Re: Vitamin D FAQ :)
i see y'all been chatting while i've been updating.
according to the info i have ;) vit D3 is well absorbed from oil, pill or glycerin preparations. it is not well absorbed by persons on ultra low fat diets, those with radical weight-loss surgeries or other abdominal surgeries (much of the intestine is missing) or those on pills like Alli. d2 or d3 can be in any form, but see OP for which is best :) ---------- Post added at 05:17 PM ---------- Previous post was at 05:06 PM ---------- re testing controversy: i don't believe there is any, quest sucks, plain and simple :duck i have long been aware of their many shortcomings. quest is the walmart of american labs. they are big, they get away with a lot. but much of what they do works and is efficient. i don't doubt that they messed up a number of vit D tests among many other mistakes they have made over the years. the fact that they are coming out and talking about it tells me that there's mucho $$$ involved. :shrug also remember that you dr. or the hospital, or a home health nurse, or midwife may draw the blood. what also matters is what lab will process it. not all bloodwork collected by the hospitals and offices is processed on site. it may well go off to quest or another facility. just ask :) as for me, i would still get a test and hope the results are helpful. :think if i were paying out of pocket anyway, i'd avoid quest though. |
Re: Vitamin D FAQ :)
there is new evidence that D2 can cause your bones to not just get "hard" but get "dense" and turn to stone.
I'm trying to find out how you can know if you're taking D2 or D3 if it doesn't specifically say. |

anything OTC should say if it's D2 (ergocalciferol) or D3 (cholecalciferol). You want D3. If your prescription doesn't say, I'd call the pharmacist until you find out which it is. |

My mother was telling me about it. I would bet Dr. Mercola had something about it :shrug3

Re: Vitamin D FAQ :)
Crystal, sadly I am 99% sure that it is ergocalciferol.

Re: Vitamin D FAQ :)
oh, it just hit me, Crystal: i wonder if your mama is talking about meds like boniva and acotnel :think they come up in vitD convos often b/c they are used for osteoporosis as well. and yes, i did hear the whole creating an artificial matrix within the bone, so on so forth. it is well outside my area of expertise and interest at this time, so i never looked into it further than reading a snippet here or there.

Re: Vitamin D FAQ :)
I just found out I am Vit D deficient. I got a call from the nurse last week that my levels were 11.3. They put me on a little green, oil filled pill...50,000 IUs once a week.
I've been reading up on it, and had no idea there was such a thing as being vit D deficient. :shifty But I am AA, so I see that dark skin is a factor in being deficient. :think I'll have to check out that scale! :tu So...my question is, what are the symptoms of being Vit D deficient? I've been reading about it and alot of the literature has a lot to say about bones, and some say things about mood swings, depression, fatigue...I've had those symptoms, more intense PMS symptoms (yup!) but I was also severely iron deficient (doing better now!) so I'm sure all that is linked to how icky I was feeling for a long time. :shifty I guess my question is, will I be able to feel a difference now that I'm taking this? I have already felt SOOOO much better after getting 2 units of blood for the iron. But I knew I wasn't 100% and still needed to be "tweaked". I'm wondering if the Vit D thing was it? :think (I didn't have the Vit D test until after the transfusion...different doctor. I had no idea they were even going to test my D levels, I didn't even know you could! :giggle I guess that says alot about my new doctor! :tu) |
Re: Vitamin D FAQ :)
Crystal is/was severely deficient..she has a few post about it around her

Re: Vitamin D FAQ :)

as i told Crystal, what you are taking is D2, not D3, latter being preferable. my greatest concern is what this deficiency is doing to you over time:increasing the risk of many many cancers and general morbidity (likelihood of becoming ill) so, i'm glad to hear you are doing some reading. we are coming to understand that vit. D levels are essential for maintaining and restoring health. |
Re: Vitamin D FAQ :)
Very helpful post, Irene, thank you. :heart
If it's any help to anyone, Vitacost has a great sale on D3 drops right now - http://www.vitacost.com/NSI-Vitamin-...-fl-oz-2000-IU Easily hidden in my kids nightly cal/mag dosage. ;) |

(thankfully, her legs straightened out very quickly after 2 mons of D3 supplementation, and Ud never know she had an issue as a baby :ptl) |
Re: Vitamin D FAQ :)
sadly, i do not believe that vitamins have good obvious deficiency symptoms: by the time you can tell, there is an *illness* (you know, scurvy, rickets, chicken blindness, all the ones with cool names :shifty )
|
Re: Vitamin D FAQ :)
My doctor told me that Vit D deficiency can contribute to muscle weakness, fatigue, mood swings, depression. But, I was severely anemic too, (and still am but not as severe) so I couldn't tell you if my symptoms were more due to the anemia. I'm sure there is an overlap. :shrug3 I know that before my blood transfusion, I felt way "off", and I knew I needed "major tweaking". But I didn't know what. After the transfusion, I feel TONS better, but I knew I still was not 100%. That was when the Vit. D deficiency was discovered, and that I'm not nearly as anemic as before, but still anemic. My mood swings and depression virtually disappeared overnight.
I expect that in about 2 months, after building both my iron stores and the Vit. D, I'll just feel even better. :tu I'm paying closer attention to how I "feel" and honestly I feel like everyday, I get better and better, not just physically but mentally and emotionally too. |
Re: Vitamin D FAQ :)
is taking Vit D daily all year a good idea? I mean, we're spending at least an hour outside now that is sunny and warm... :think Would it still be good to supplement?

I cut out my kiddos D for the summer as I don't know their levels and they get a ton of sun. I still take mine because I know I am very deficient. |

Is there such thing as getting "too much" Vit D? :think

I have supplemented Vit D for years before doctors were saying that we should, simply because after 5 minutes in the sunlight, I start to get sunburn. So I just have done it on my own. When my doctor said that as a postmenopausal woman, I needed to supplement, I said ;)"Good idea!", and :Dcontinued on as I always have (except now I don't have to remember to not mention it at an appointment). I get some of both D2 & D3, but try to let the D2 be the "incidental" stuff. And my favorite yogurt (Stony Field) is supplemneted with :rockonD3!! |

What about sunscreen? :think I'm AA so it takes me much, much longer in the sun to absorb Vit D than a caucasion person. And from what I understand, or at least I thought I read somewhere that sunscreen hinders Vit D absorption. So I am less stressed about putting sunscreen on me or dd :shifty because I figure we need to be able to get Vit D. in our system. She is biracial so lighter skinned than me, and tans really well :tu but I feel like she's probably not gettin enough Vit D either...so why bother using sunscreen? :shrug3 Thoughts? |
Re: Vitamin D FAQ :)
Well there are a few posts in the suncreen thread that take CLO and use coconut oil so they are protected against the bad rays of the sun but get the benefits of it too

Re: Vitamin D FAQ :)
Ditto. I only use sunscreen when there is a risk of sunburn. My kids are all fair skin w/ blue eyes so I have to gradually increase their sun exposure but by mid summer they get a lot of sun w/ no sunscreen. I use sunscreen when they'll be swimming for a long time.
And sunscreen DOES prevent the body from making vit d. :yes2. It's one of the reasons for the rising cancer rate. :yes2 Posted via Mobile Device |
