20,000 iu D3 at 1st: I advise you take 20,000 iu of vit D3 a day for 2 months then recheck your levels.Your goal is 50-80 ng/ml ; you can adjust your dose as needed to maintain that- see https://www.vitamindcouncil.org/further-topics/i-tested-my-vitamin-d-level-what-do-my-results-mean/. Once you find the dose that maintains you at 50-80 continue it indefinitely. Most need 5-8000 iu/day. Can be serious- see comment: ...Read more

Are there different tests for Vitamin D & Vitamin D3? Specifically: Vitamin D3 (25 OH D) and 25 (OH) Vitamin D?

Are there different tests for Vitamin D & Vitamin D3? Specifically: Vitamin D3 (25 OH D) and 25 (OH) Vitamin D?

Yes: When there is a reason to test, testing for 25-OH-VitD2 level and for 25-OH-VitD3 level, plus adding the results to get the total vitamin D level, can help the doctor check the source of the vitamin deficiency and the treatment progress. There is debate over when it would be needed to do these tests. Some doctors feel that giving people more vitamin D would avoid deficiencies and avoid lab tests. ...Read more

There is: No advantage to having a vitamin d level above normal. That's an awful lot of vitamin d per day; luckily it's not toxic to most people. 2000/day is usually enough to keep things normal for most people. ...Read more

Vitamin D: Research shows that raising your vitamin d level can boost immunity, elevate mood, and more.

Experts say between 50-80 is optimal. 20s or 30s is minimal. Ask doc about over the counter supplementation. ...Read more

I had tests done  found out I'm vitamin d  defeciant what problems can this cause?

Usually ok: Low 25 vitamin d can be associated with low dietary calcium uptake/bone health issues... And there are other potential health benefits of vitamin d on immune function. However most adult with d deficiency do not have overt symptoms. If tested because of bone health concerns, take the vitamin d doses prescribed by your doctor. Otherwise, probably ok to just take an OTC supplement to treat. ...Read more

Vitamin D was 18, after improving diet went up to 23.1 in 6 mos. Now been in summer sun alot- recent test 23.6. Why won't food/sun get it any higher?

Would not worry: While many people believe a healthy vitamin D level has to be >30, I and others believe that >20 is fine. Some people seem to get more of a boost in their D level from sun than others. You could take a vitamin D supplement of 600-1000 units per day to safely boost your D level a bit but I don't think it is necessary ...Read more

Why have lab tests: You don't know what you don't know. I deal with a proactive approach to health in functional medicine, so I do a lot of labs. Vitamin D is a fat soluble vitamin, so you want to know your level before you take a very high dose. Being low is a risk factor for osteoporosis, major depression, and even increases your risk for several cancers. ...Read more
