My Vitamin D update- What's yours?

[HRTstudent]

Thanks

For what its worth, my doctor who recommends and uses vitamin D said he wasnt concerned if my vitamin D went over 100. He might have mentioned there are no known toxicity cases of it, or something along these lines... basically I wasnt going to put myself in any acute danger if I went over 100.

Now if I went over 200... then maybe but once I got to 90's I cut my dose to 5k IU daily. I have yet to get follow up bloods for that, but I will in a few months probably.

Thanks for the link Kelkel and if you and Bass could post any rise,or drop in calcium from your last BW I would appreciate it. I did my blood draw for vit D last week and see dr tomorrow. Hopefully the results are in on the BW and my bone density scan which was done yesterday.

Coming out of winter this past May my Vitamin D level was 41, which wasnt too bad. After a summer of going to the beach at least once per week, my BW came back today @ 61.1. Not bad considering I've had little to no extra D supplementation. Is there really an optimal level we should be at though?

no one really knows, but mine has been hovering at about 87 or so and really don't know if i feel any different! i guess the higher the better as long as you're in range.

Well take this with a grain of salt but this is what one of my tests (NutrEval) had for Vitamin D:

Interesting abstract I came across... (did not read full paper)


Vitamin D3 supplementation (4000 IU/d for 1 y) eliminates differences in circulating 25-hydroxyvitamin D between African American and white men
http://ajcn.nutrition.org/content/96/2/332.abstract

Background: African Americans suffer disproportionately from diabetes and cardiovascular disease and are significantly more likely to have suboptimal concentrations of circulating 25-hydroxyvitamin D [25(OH)D]. The results of epidemiologic and observational studies suggest that there is a link between vitamin D deficiency and the risk of cardiometabolic disorders, which underscores the importance of maintaining healthy concentrations of 25(OH)D.

Objective: The objective was to investigate whether daily supplementation with 4000 IU vitamin D3 for 1 y would eliminate any disparities in circulating concentrations of 25(OH)D between African American and white men.

Design: Serum concentrations of 25(OH)D were measured every 2 mo in 47 subjects who received a daily oral dose of 4000 IU vitamin D3 for 1 y.

Results: More than 90% of African Americans had serum concentrations of 25(OH)D <32 ng/mL, and approximately two-thirds had serum concentrations <20 ng/mL. Furthermore, there were significant disparities in serum concentrations of 25(OH)D between African American and white men. Supplementation with 4000 IU/d for 1 y eliminated any significant differences in circulating concentrations of 25(OH)D between African American and white men.

Conclusion: The results of this clinical study show the feasibility and efficacy of this approach in the elimination of hypovitaminosis D, which is a widespread health disparity among African Americans. This trial was registered at clinicaltrials.gov as NCT01045109.

What level of Vitamin D, 25- Hydroxy do people shoot for?

life extension foundation recommends an optimal range of 50-80 ng/ml (Life Extension Magazine May 2012).

apparently, a recent study by the american heart association found "Those whose 25-hydroxyvitamin D level exceeded 100 ng/mL had an atrial fibrillation incidence 2.5 times greater than people in the safe ranges (below 100 ng/mL)."
