Question 1

which brand of d vitamin out there is the best or most reliable?

Accepted Answer

Depends: Look for USP or consumerlabs certification for quality. Choose d3. However, before supplementing make sure you need it. Ask your doctor to check your blood levels. Don't supplement if you don't need something. Waste of money and may be harmful.

Question 2

how much vitamin  d3 should ou take a day? i have a bottle of vitamin  d3 5000iu in which i take two a day. one am one pm since i am low in d. ok?

Accepted Answer

Vitamin D3: Usual dose is not more than 5000 units daily. I take that and my level is right in the middle of the normal range (50) Bear in mind that persons who have had gastric bypass surgery will absorb Vitamin D more readily and can become intoxicated with even 5000 units daily. Thanks for trusting HealthTap!

Question 3

can too much of vitamin a and d be bad for you?

Accepted Answer

Yes: Water-soluble vitamins (b, c) being water soluble are easily eliminated from the body if excess is consumed. Fat-soluble vitamins (d, a, k, e) aren't as quickly eliminated from the body, but rather are stored in fat tissues and in various organs throughout the body. So toxicity can occur. See chart.

Question 4

if i take calcium with d could i also take vitamin d3?

Accepted Answer

KEEP D 3 LEVELS: Below 3000 units a day total.

Question 5

what if i melted vit d, would the skin absorb the vitamin?

Accepted Answer

No telling: Dyshidrosis only affects the palms and soles, so what you have on your arms is up for grabs.

Question 6

what is the difference between taking vit d and vitamin d3?

Accepted Answer

D is a  general term: Vitamin d comes in two forms, vitamin d3 is made in the skin after stimulation with ultraviolet light from sun shine and vitamin d2 comes from irradiated mushrooms.  They both have the same effects but vitamin d3 stays in the blood for a longer time than d2.

Question 7

what effect could taking too much vitamin a and d have on you?

Accepted Answer

Can be toxic: Fat soluble vitamins can be toxic when overdosed.  That includes a, e, d, and k.  Overdose can cause problems with skin, hair, bones, liver function, and blood pressure in the brain.  Hair can fall out, headaches can occur, and if pregnant,  toxicity can case birth defects in the infant.  Be very carefully with all fat soluble vitamins.  If you have concerns about your levels, talk to your doctor.

Question 8

what are some things that can cause low vitamin a and d levels?

Accepted Answer

Bad diet, indoors: It is rare to have low vitamin a in the usa as even limited diets contain enough of this vitamin to meet the body's needs.  Vitamin d however is dependent partially on diet and also on sunlight so low vitamin d is common and it is reasonable to supplement this with 2000-4000 units of d3 per day especially in poorly lit climates like seattle and alaska.

Question 9

what does vitamin d do?

Accepted Answer

To keep you healthy: Good for your general health.

Question 10

what decreases vitamin d?

Accepted Answer

The roof: Most of the vitamin d in the body is produced by exposure to the sunshine. But, nowadays we live, work and drive under a roof so our body is not exposed to the sunlight.  Check this video i made about vitamin d. http://otwithmd.com/vitamin-d/.
