Question 1

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

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

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 4

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 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

started femara (letrozole) 2 weeks ago;side effects r minimal. one night every bone in my 2 feet cramped ;dr rec  vitamin k n magn will these interact with femar?

Accepted Answer

No interference: You are probably taking vitamin-d(not vitamin-k).

Question 7

i took one dose of vitamin k2 (mk7) and had awful side effects (palpitations, chest pain, headache, stomach ache, etc). i was just wondering can vitamin k cause blood clots in your body?

Accepted Answer

: This was likely an individual allergic reaction to some material (even a  trace amount) in the product, not the vitamin K which is present in foods you eat. The natural vitamin K is a co-factor in the formation of the blood factors that allow you to clot normally. The exposure you cited is unlikely to have any effect on your clotting, or anything else. I would avoid that product in the future.

Question 8

is there any need to take extra vitamin k?

Accepted Answer

No: Most do not require extra vit k.  Vit k may be beneficial for a select group of patients - those with intravenous feedings, those with malabsorption and those on long term antibiotics. Sometime pts with difficult to control INR while on Coumadin (warfarin) are given low dose vit k to help regularize their numbers.

Question 9

can you please list foods high in vitamin k?

Accepted Answer

Natto: Green leafy veggies and something called natto which is a fermented product that i hear is popular in japan.

Question 10

does jujube has vitamin k?

Accepted Answer

Jujube: No, green vegetables are a source of vitamin k. Jujube does, however, have alot of vitamin c, and when dried b vitamins (riboflavin and thiamine).
