Question 1

what are the sources of vitamin d3?

Accepted Answer

The best is the sun : I give all of my patient 2000iu of d3 daily not kids i give the 1000iu if older than 4.

Question 2

what would be recommended to transition from vitamin d3 to d2?

Accepted Answer

Same dosage.: The d3 and d2 are equally effective at the same dose.

Question 3

what is the rda for vitamin d3?

Accepted Answer

Vitamin D RDA: The rda for vitamin d for adults through age 70 is 600 iu, which increases to 800 iu after age 71. For pregnant and lactating mothers, intake of 600 iu is recommended.

Question 4

is vitamin d3 the same as calcium?

Accepted Answer

Calcium &amp; vitamin D.: Calcium and vitamin D are different, but they work together as building blocks for our bones.  Supplementing calcium and vitamin D can help keep bones strong and hopefully prevent or delay the development of osteoporosis when used in combination with weight-bearing exercise.

Question 5

can vitamin d3 softgel pills go bad?

Accepted Answer

Yes: The vitamin d3 softgel has oil in it. All oil can go rancid over time. Be sure the bottle has been properly stored, and check the expiration date on the bottle.

Question 6

do i need take calcium or vitamin d3?

Accepted Answer

Supplement Need: The only way to know if you need supplemental calcium or vitamin D3 is to be lab tested by your doctor.  Many people are low in Vitamin D3 but you may not be.  Also, do not take calcium w/out a co-factor such as D or it will do more harm than good.  Peace and good health.

Question 7

do vitamin d3 help you to lose weight?

Accepted Answer

No, no effect: Hi. No, vitamin D3 supplements have no effect on weight loss. Healthy diet, regular exercise. If you're overweight or obese, you can talk with your doc about more aggressive ways to lose weight. Good luck!

Question 8

how fast can vitamin d3 liquid drops work?

Accepted Answer

Fairly quickly: Vitamin d3 liquid drops are well-absorbed & should quickly get into your system. If you are deficient in d it may, however, take some time to bring your levels up to optimal levels. I feel most adults should take 4000-5000 units a day to achieve optimal vitamin d levels. If your level is low you could safely take 10, 000 units a day for a couple weeks to speed bringing your levels up.

Question 9

does vitamin d3 have antiviral properties?

Accepted Answer

Perhaps: Vitamin D plays a vital role in maintaining proper bone structure. Evidence has also suggested that vitamin D plays a major role regulating the immune system, perhaps including immune responses to viral infection.  I wish you well with your health!

Question 10

is it safe to take 5000 of vitamin d3 daily?

Accepted Answer

Yes, may need more!: I recommend all adults take 5000-10,000 iu of D3 daily during fall and winter months (it's possible to get adequate D from the sun in spring/summer but take year-round if you don't get much sun). 
Optimal blood levels are 50-80 and that's the dose most need to attain those levels.One must take 40,000 iu/day to become toxic! Take K too! See http://tinyurl.com/2chkcer and http://tinyurl.com/4rqhnn4
