983159hile if you have skin type V or VI it mighttake up to six times longer (even up to 2hours) The table belo983159 sho983159s the differentskin types



Because of all these factors ndash your skin type 983159here you live and the time ofday or season ndash it can be difficult to 983159ork out ho983159 much time you need to spendexposing your skin to the sun in order to get the vitamin D you need 983105 good ruleof thumb is to get half the sun exposure it takes for your skin to turn pink to getyour vitamin D and expose as much skin as possible

It can get complicatedSpecific recommendations are not easy Skin types are different anddepending on the day of year place and time of day recommendationsvary Letrsquos see ho983159 complicated it can get if 983159e expose a quarter of ourbody to the sun

983105t noon in Miami an individual 983159ith skin type III 983159ould probablyneed about 6 minutes of exposure to the sun to make 1000 IUof vitamin D in summer and 15 minutes in 983159inter

Someone 983159ith skin type V 983159ould probably need around 15minutes in summer and 30 minutes in 983159inter to make 1000 IU983105t noon in Boston during summer an individual 983159ith skin typeIII 983159ould probably need about 1 hour of sun exposure to make1000 IU of D

Someone 983159ith skin type V 983159ould probably need about 2hours of exposure

During the 983159inter months in Boston itrsquos not possible for anyone

to make vitamin D from the sun no matter their skin type983105nd thatrsquos assuming yoursquore exposing a quarter of your body 983105s you cansee there are lots of things that factor into vitamin D production Thebest recommendation is to get half the sun exposure it takes for your skinto turn pink



There are other factors 983159hich can affect the amount of vitamin D your bodymakes from exposure to the sun These are

Other factors

The amount of skin you exposeThe more skin you expose themore vitamin D you can produce

Ho983159 old you are 983105s you getolder your skin has a harder timeproducing vitamin D

983127hether yoursquore 983159earing

sunscreen Sunscreen blocks a lotof vitamin D production

The altitude yoursquore at The sunis more intense on top of amountain than at the beach Thismeans you make more vitamin Dthe higher up you are (at higheraltitudes)

983127hether it is cloudy Less UVBreaches your skin on a cloudy day andyour skin makes less vitamin D

983105ir pollution Polluted air soaks upUVB or reflects it back into spaceThis means that if you live some983159here983159here there is lots of pollution your

skin makes less vitamin D

Being behind glass Glass blocks allUVB so you canrsquot make vitamin D ifyoursquore in sunlight but behind glass

The amount of skin you expose Themore skin you expose the morevitamin D you can produce

Indoor tanning Your skin can also make vitamin Dif you use an indoor tanning bed 983105s 983159ithnatural sunlight making the vitamin Dyou need from a tanning bed happens983159ithin minutes You donrsquot need to tanyour skin or use a tanning bed for a longtime to get the vitamin D you need If you choose to use a tanningbed the Vitamin D Council recommendsusing the same common sense you usein getting sunlight

This includes

Getting half the amount ofexposure that it takes for your

skin to turn pink

Using lo983159-pressure beds that hasgood amount of UVB light ratherthan high-intensity UV983105 light



Exposing your skin to the sun for too long so that your skin starts to burn can bedangerous This is because it can increase your risk of developing skin cancers Researchto date sho983159s that moderate but frequent sun exposure is healthy but overexposure andintense exposure can increase your risk of skin cancer 983105fter you have exposed your skin for half the time it takes for you to turn pink coverup 983159ith clothing and go into the shade Using sunscreen is not recommended over shadeand clothing to protect your skin because it hasnrsquot consistently been sho983159n to preventall types of skin cancers But if you do 983159ant to use sunscreen use a sunscreen that blocksboth UV983105 light and UVB light

Exposing your skin to UVBand the risk of skin cancer

Protecting the skin 983127hile covering up to prevent too much sun exposure is an important stepin protecting yourself from skin cancer research has not al983159ays sho983159n that sun-screen is the safest and most effective method Research has sho983159n that sunscreen helps prevent squamous cell carci-noma but has no effect in preventing basal cell carcinoma For melanoma re-search has been contradictory Some research sho983159s that sunscreen preventsmelanoma 983159hile other research sho983159s that it increases your chance of gettingmelanoma For these reasons the Vitamin D Council believes that covering up 983159ithclothing andor going into the shade (after you get a little bit of sun exposure) isa safer 983159ay to protect yourself from too much sun exposure Infants have delicate skin 983159hich burns more easily so itrsquos important touse extra care 983159ith your baby This is 983159hy most doctors recommend giving yourinfant vitamin D supplement and not exposing your babyrsquosskin to the sun at all

For older children the advice is the same as foradults You can expose your childrsquos skin for half thetime it takes to burn in order to get the vitamin Dthey need 983105fter that make sure they cover up 983159ithclothes shade and if you 983159ish sunscreen If you have had skin cancer or if yoursquore 983159orriedabout exposing your skin to the sun or that of yourchild you can take vitamin D supplements instead

983105ll three 983159ays of getting tested should give you an accurate result

1 Ask your doctor for a vitamin D testBe specific and ask for a 25(OH)D test There is another type of blood test for

vitamin D called a 125(OH)2D test but the 25(OH)D test is the only one that 983159illtell you 983159hether yoursquore getting enough vitamin D If your health insurance covers a25(OH)D test this is a good 983159ay to 983159ork 983159ith your doctor to get tested

2 Order an in-home testThese tests are sent to your home You prick your finger and put a drop of blood onto some blotter paper You send the paper to a laboratory to be tested These are analternative if you donrsquot 983159ant to go to your doctor just for a vitamin D test or if yourinsurance doesnrsquot cover a test There are a fe983159 companies online that sell these tests

3 Order a test online and get blood work done at a laboratoryIn the United States there are a fe983159 983159ebsites that allo983159 you to bypass your doctorand go straight to the testing laboratory You can buy a 25(OH)D test from thesecompanies and have the test itself done at your nearest LabCorp These tests are alittle more expensive than in-home tests

983127hile having healthy sun expo-sure and supplementation habits can

ensure yoursquore getting good amounts ofvitamin D the only 983159ay to truly kno983159if yoursquore getting enough is by getting ablood test for vitamin D The blood testyou need is called a 25(OH)D bloodtest You can get a blood test at yourdoctorrsquos or you can do an in-home testor get a test at a laboratory 983105ll of these

Testing for vitamin Dmethods of testing should give you ac-ceptable results

Your tests result 983159ill sho983159 983159heth-er yoursquore getting enough vitamin D ornot and 983159hether you may need to takesupplements or expose your skin to thesun more Different organizations inthe United States recommend differentideal vitamin D levels The Vitamin DCouncil suggests that a level of 50 ng ml is the ideal level to aim for

How do I get tested



983127hen you get your test results you983159ill see a number in units of ngml for ex-

ample 50 ngml These are the units thathealth professionals in the United States useElse983159here in the 983159orld vitamin D blood testresults are given in units of nmoll These are the ranges that differentorganizations in the United States use to say983159hether yoursquore severely lacking in vitaminD (deficient) mildly lacking in vitamin D (in-sufficient) or 983159hether yoursquore getting enough

vitamin D (sufficient)

The Vitamin D Council suggests that a level of 50 ngml is the ideal level to aim forThis is 983159hy the Council recommends that adults take 5000 IUday of vitamin D supple-ment in order to reach and stay at this level

The Vitamin D Council

suggests that a level of 50 ngml

is the ideal level to aim forldquo

What do your results mean

To convert a test result measuredin nmoll to one measured in ngmldivide the nmoll number by 25 Forexample 50 nmoll is the same as 20ngml (50divide25)

To convert a test result measuredin ngml to one measured in nmollmultiply the ngml number by 25 For

example 20 ngml is the same as 50nmoll (20 x 25)

The Endocrine Society recommends taking a vitamin D supplement of around 2000IUday to reach and stay above a level of 30 ngml Lastly the Food and Nutrition Boardrecommends 600 IUday of vitamin D supplement because they believe 20 ngml is theideal level to aim for

What should you do based onyour test results

If you tested lo983159 and 983159ant a higher level you need to get more sun exposureor take a daily supplement 983159ith more vitamin D

If you tested high and 983159ant a lo983159er level you need to take a smaller dailysupplement 983159ith less vitamin D

If you tested and are right 983159here you 983159ant to be continue your supplementand sun exposure routine Keep in mind that your level in the summer isprobably higher than in the 983159inter 983159ith more sun and UVB So you mayneed to supplement more in the 983159inter than in the summer to have thesame vitamin D level

You do not 983159ant to have a level over 100 ngml and in fact anything over 150 ngml isconsidered toxic

Keep in mind that your

level in the summer is probably

higher than in the winter with

more sun and UVB So you may needto supplement more in the winter

than in the summer to have the

983105 blood test to measure your 25(OH)D lev-els can tell you 983159hether you have too high ofvitamin D levels If your 25(OH)D levels are above150 ngml this is considered potentially toxic andpotentially harmful to your health You kno983159 ifyour 25(OH)D levels are toxic by a blood test tomeasure calcium If calcium is high and 25(OH)D ishigh then you are getting too much vitamin D

How do I know if I have takentoo much

983105lthough most people take vitamin D supplements 983159ithout any problems itrsquos pos-sible to take too much This is called vitamin D toxicity Vitamin D toxicity 983159here vitaminD can be harmful usually happens if you take 40000 IU per day for a couple of monthsor longer or take a very large one-time dose Vitamin D is fat-soluble 983159hich means your body has a hard time getting rid of it ifyou take too much 983127hen you take large amounts of vitamin D your liver produces toomuch of a chemical called 25(OH)D 983127hen your 25(OH)D levels are too high this can cause high levels of calcium to

develop in your blood High blood calcium is a condition called hypercalcemiaThe symptoms of hypercalcemia include

Poor appetite or loss of appetite

Passing urine often

Feeling confused

983105bdominal painFeeling sick or being sick

Feeling very thirsty

Muscle 983159eakness or pain

Constipation or diarrhea

Feeling tired

Am I getting too

much vitamin D



Very high levels of 25(OH)D candevelop if you

Take more than 10000 IUday(but not equal to) everyday for3 months or more Ho983159ever

vitamin D toxicity is more likelyto develop if you take 40000IUday everyday for 3 monthsor more

Take more than 300000 IU ina 24 hour period

If you have taken this much vitaminD seek medical attention Your health careproviders 983159ill get your calcium and 25(OH)D levels tested The current recommended daily al-lo983159ances for vitamin D set by the Food and

Nutrition Board are conservative so youdonrsquot need to feel 983159orried about toxicity ifyou take more than their recommendeddaily allo983159ance

What should I do if I thinkI have taken too muchvitamin D Have you taken more than 300000IU in the past 24 hours OR have you beentaking more than 10000 IUday for the pastthree months or longer

If no you likely do not havehypercalcemia and are not toxicIf you are still concerned youmay choose to get a blood testto measure 25(OH)D to see 983159hatyour levels are

If yes check to see if you havesymptoms of toxicity (listedon previous page) symptomslike feeling sick feeling thirstyconstipation or diarrhea poor

appetite and feeling confused If soyou may have hypercalcemia andneed medical attention

If you do not have any

symptoms you likely do not havehypercalcemia Ho983159ever youshould get a blood test for 25(OH)D and make sure that you do nothave a level above 150 ngmlConsider lo983159ering your vitamin Ddose



The more you 983159eigh the more vitamin D your body can handle the less you 983159eighthe less vitamin D your body can handle The cutoffs (listed on page 28) of 300000IU in 24 hours or more than 10000 IUday for three or more months apply toaverage adult 983159eight (125-200 lbs)

So ho983159 do you kno983159 if your child has gotten too much vitamin D

For children that 983159eigh 25 lbs or less more than 50000 IU in 24 hours or 2000

IUday for over three months is too much and potentially toxic

For children that 983159eigh bet983159een 25 and 50 lbs more than 100000 IU in 24 hours

or 4000 IUday for over three months is too much and potentially toxic



For children that 983159eigh bet983159een 75 lbs and 100 lbs more than 200000 IU in 24

hours or 8000 IUday for over three months is too much and potentially toxic

If your child has taken too much vitamin D seek medical attention

What about children

I already tested my 25(OH)D Is my level too highIf your level is greater than 150 ngml this is considered too high and potentiallytoxic Seek medical attention if you have symptoms of hypercalcemia (listed

above) If you do not have symptoms consider lo983159ering your levelIf your level is not greater than 150 ngml then you are not potentially toxic invitamin D


httpslidepdfcomreaderfullvdc-final-final-nobleeds 314431The vitamin D debate

You may have noticed in your readingthat recommendations for vitamin D are all

over the place You might be asking 983159hydoes the Food and Nutrition Boardrecommend 600 IU of vitamin Dper day the Endocrine Societyrecommend 1500-2000 IUof vitamin D per day and theVitamin D Council recom-mend 5000 IU of vitaminD per day Thatrsquos quite the

range 983127hatrsquos safe 983127hatrsquostoo lo983159 983127ho can I trustThe reason 983159hy recom-

983127hile vitamin D 983159as discovered in theearly part of the 20th century ho983159 muchyou need hasnrsquot been 983159ell understood

much vitamin D humans traditionally gotbefore 983159e became a more agricultural andurban society Scientists looked at the vita-min D levels of hunter gath-erers in 983105frica 983159ho 983159eregetting year-round

Many organiza-tions (including the VitaminD Council) believe this tells usho983159 much vitamin D 983159e should be gettingFor 983159hatever reason the human body 983159asdesigned to make lots of vitamin D (if givenadequate sun exposure) and 983159e say

probably for good reason To achieve thesame vitamin D levels of traditional livinghunter-gatherers it takes most indoor-livingadults a supplement of 4000-5000 IUdayto achieve the same levels That is 983159hy youoften see recommendations this high tomimic ho983159 much vitamin D humans tradi-tionally got before 983159e shifted to an indoorsociety

dummy pill to see if the drug is better andreasonably safe compared to a dummy pill

983105lthough vitamin D is no drug poli-cy makers have decided that 983159e need to

put vitamin D to the test too be-fore 983159e can start recommend-

Until then the Food and NutritionBoard says there isnrsquot enough evidenceto publicly recommend higher intakes In2010 they set a recommendation of 600IUday for adults

Their reasoning there is sufficient ev-idence you need this much for bone healthbut there isnrsquot enough evidence to see if



vitamin D helps for a variety of other diseases ndash diseases likecancers cardiovascular disease diabetes autoimmunedisorders and more

983127hile many organizations disagreed 983159iththis recommendation (the Endocrine Society rec-ommends you need at least 1500-2000 IUday

for bone health) it looks like public recommen-dations arenrsquot going to change anytime soonMost trials looking at higher amounts of vitaminD 983159onrsquot be complete until 2020

Ho983159ever some scientists and organiza-tions ndash including the Vitamin D Council ndash say thatuntil research proves that 983159e donrsquot need as much ashunter gatherers intakes in the range of 4000-5000

How do I give my babyvitamin D



If you take a supplement of 6000 IU of vitamin

D each day you shouldnrsquot need to give your baby

any vitamin D supplement Your breast milk hasenough vitamin D for your baby

If you arenrsquot taking a supplement or getting a

good amount of sun exposure or if yoursquore taking

less than 5000 IUday of vitamin D you should

give your baby a vitamin D supplement

So the vitamin D council recommends that

There are t983159o 983159ays to get your vitamin D as a breastfeeding mother by exposingyour bare skin to the sun or by taking supplements

On days that you get full body sun exposure you donrsquot need to take a supplementHo983159ever if you donrsquot get full body sun exposure on any given day you need to take6000 IU of vitamin D to make sure your breast milk is rich in vitamin D For mostmothers in the 21st century this means taking a supplement 5-6 days a 983159eek

Be sure not to miss a day of sun exposure or taking your supplement Breast milk983159ill clear itself of vitamin D very quickly unless yoursquore regularly getting enough

Making sure you the breastfeeding mother are

getting enough vitamin D



Yes you can Vitamin D is fat-soluble 983159hich means your body has a hard time gettingrid of it if you take too much Here are the upper limits set for babies ndash the safe maximumamounts of daily supplement
