Question 1

children up to 4 years old we have to give 10 g of vitamin d3 daily, but we still give this to our 5 year old son every day. could this have adverse effects? could we better stop to give it? we also give him vitamin c supplement daily, is this ok?

Accepted Answer

: Vitamin C &amp; D are often added or already present in food in our regular diet (i.e. cereal, milk, orange juice). The Vitamin D recommended dietary allowance (RDA) for children 4-8 years old is 600 IU/day (15µg). The upper limit is 3000 IU/day. For Vitamin C the RDA is 25 mg/day, the upper limit is 650 mg/day.

Question 2

i was wondering what are the adverse effects of taking excess dosages of vitamins and calcium?

Accepted Answer

Confused question: No toxicity from water soluble vitamins. Toxicity from fat-soluble vitamins. Toxicity from calcium.

Question 3

are there any adverse effects of coming into contact with sunlight when taking vitamin b tablets?

Accepted Answer

NO: B vitamins do not have significant interactions with sunlight.  Vitamin a is a different story, as it can increase sensitivity to sunlight.

Question 4

i want to know about vitamins and minerals that can help me to counter the adverse effects (diabetes risk) of aripiprazole 15 mg.  i'm doing excercise

Accepted Answer

Preventative diet.: Evidence for vitamins and minerals reducing diabetes risks evidence is not strong. A  better bet is to adapt a preventative diet to lower risks.

Question 5

my vitamin d level is 19ng/ml the lab reference is 30-100. nih website says 20ng/ml is adequate, and above 50 has adverse effects, but md says above 30 is optimal. do i need to supplement and how much? md advised 5000 iu/day, i think it's excessive?

Accepted Answer

: Levels of 50 nmol/L (20 ng/mL) or above are adequate for bone and overall health. Levels below 30 nmol/L (12 ng/mL) are too low &amp; might weaken your bones &amp; affect your health. Levels above 125 nmol/L (50 ng/mL) are too high and can cause health problems.For you, the 19 is too low and should be increased and initially increasing with 5000 IU per day for about a month, then 1000 IU per day usually.

Question 6

what is a good and safe amount of vitamin d3 that a healthy 47 year old woman should take daily? are there any possible side effects associated w/ d3?

Accepted Answer

D3: Please get your D3 tested by your doctor and then you will know the right amount to take daily.  Experts suggest your level be between 50 &amp; 80 for optimal benefit.  You can OD on D3 and have some side effects like fatigue &amp; GI symptoms.  Peace and good health.

Question 7

what's the latest research on the interaction/detrimental effects of vitamin a (eg from raw carrots) on vitamin d3 (from sunlight) effectiveness?

Accepted Answer

Militant fringe: This is at present a fringe idea, primarily the work of a handful of pro-vitamin-d, anti-vitamin-a militants on anti-doctor websites; the centerpiece is a 2009 number-crunch journal article on vitamin d levels and colon cancer with a tiny sidebar on vitamin a. I hesitate to draw cause-and-effect conclusions from studies based only on statistics without an obvious mechanism.

Question 8

i've heard a lot about the benefits of vitamin d3. what is a safe amount to take in supplement form? are there any side effects/risks of taking it?

Accepted Answer

5-10,000 iu/day: There are many proven benefits of Vitamin D3. While the RDA is only 600-800 iu/day, many experts recommend 5-10,000 iu/day to achieve optimal serum levels of 50-100. The only hazard is from taking too much, but one has to take at least 40.000 iu/day for months to get toxic.  It's wise to take some Vit K2 with it.

Question 9

what amount vitamin d3 should i take?

Accepted Answer

Vitamin D Dose: Vitamin D3 is often too low in patients these days.   There are many reasons for this, including less time in the sun and more sunscreen.  Also, vitamin D is used in the operation of approximately 350 genes, including many involved with detoxification.  We have many more chemicals that need detoxifying over the past 20 years or so.

It varies how much is needed.  4, 000 i.u. is usually safe.  Test.

Question 10

is vitamin d3 dangerous for your health?

Accepted Answer

No.: Helps bones, and is strikingly associated with breast, prostate, and colon cancer reductions, up to 50%.  Also associated with cardiovascular health and lessens heart attacks and strokes.  Vitamin d3 is really a hormone.  Daily amounts of 5000iu or less are not harmful. I do 5000iu/day!
