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

can acid reflux worsen by taking biotin, b12, omega 3 fish tabs. vitamin k2 ,  buffered vitamin c,vitamin d3 have barrett's esophagus and a hernia.

Accepted Answer

Possibly fish oil: Fats including fish oil can sometimes aggravate reflux; this is less likely if taken with food.
But certain supplements are proven beneficial for reflux, esp. melatonin. See http://www.greenmedinfo.com/blog/5-natural-heartburn-remedies-proven-beat-drugs
and http://www.denvernaturopathic.com/MelatoninandGERD.htm

Question 7

what are the effects of vitamin c overdose?

Accepted Answer

Inconsequential : Vitamin c is water soluable, therefore amounts taken in excess of dietary needs are quickly excreted by the kidneys.  Thus vitamin c has a very low toxicity.  In rat studies the ld50 (dose that kills 50%) is very high.  We have no data in humans to compare.  One might expect diarrhea and/or abdominal cramping but nothing dangerous.  If intentional overdose seek, psychiatric care immediately.

Question 8

what are the side effects of taking vitamin c

Accepted Answer

Diarrhea. : Better health, less illness, and diarrhea is your gut is sensitive to the dose or preparation you choose to take. The whole vitamin c complex is more effective than plain ascorbic acid.

Question 9

are there any side effects of vitamin c megadoses to fight flu symptoms?

Accepted Answer

Laxative effect: Vitamin c is extremely safe. Excessive doses (usually over 5000 mg a day) can cause a laxative effect, but it is advised to take it until you get loose stools when you have the flu. Vit. C can interact with certain medications, esp. Coumadin (warfarin) (which interacts with everything!). See http://lpi.Oregonstate.Edu/infocenter/vitamins/vitaminc/  see my comment for more info.

Question 10

vitamin c abilify (aripiprazole) 
is there side effects with vitamin c ?

Accepted Answer

Vit C & Abilify (aripiprazole): You can take these two with no conflict.  Vitamin c is water soluble and is a necessary vitamin for many processes in your body.  People usually tolerate it well, because dietary excesses of it are excreted.  At higher doses (above 1000 mg/day by mouth) it can cause nausea, vomiting, and diarrhea.  It doesn't do this in everyone.
