does taking high dose of vitamin d supplements ( around 8-10,000 iu daily) affect calcium levels or the parathyroid gland? I do not take any calcium supplements. Thanks
what about d3 competing with K2?
yeah it should actually increase it, because it increases the absorption of minerals
Vitamin D will actually help absorption of calcium and help move it to the correct locations in your body i.e. bones instead of artery walls(plaque).
Vitamin D is fat soluble so you can take a pretty huge dose all at once, like 100,000 IU and not get another dose for 1-2 months, but what I do is 5000 IU every other day.
Really you should get a blood test to check your actual levels. The one you want is 25 OH vitamin D test which is pronounced 25 hydroxy vitamin D. This is the most active form of vitamin D in the blood so is the one you want to test.
The general suggestion is to have 75 ng/mL but some research is suggesting even higher levels towards 100 ng/mL may be beneficial.
What exactly are you trying to accomplish with 8-10,000 IU per day?
thanks for the replys. I am taking around 8-10,000 ius daily to try to get my d3 blood test into the 75-100 range. When i was taking 4-5000ius daily my blood test of d3 was in the mid 50's. I know there is a relationship between calcium and vitamin d, but am not enterily sure the physiology behind it and why there is a realtionship, and trying to make sure I dont totally mess up calcium levels or somehow affect the parathyriod.
Some good information on how vitamin D can help calcium absorption in the small intestine. It's kind of technical though.
Basically they're saying that there are passive and active ways calcium is absorbed. Vitamin D can increase the active calcium transport channels in the ileum(part of the small intestine).
I'm not sure if overdoing vit. D would affect the parathyroid but as long as your 25-OH D levels are 75-100 there should not be any problem. This is a normal and recommended range by a lot of people and is safe.
LEF magazine recently had a good article on Vitamin D. Level recommended is 5000ius
I noticed some D3 supps have soy bean oil listed as the first ingredient. Others use fish oil . I'm guessing the ones without soy bean oil would be better. Does it matter?
The amount of oil you'll be ingesting is tiny since the D pills are tiny. I wouldn't worry that much about it. The ones I have are olive oil. There needs to be some oil in the pills since Vit. D is fat soluble so they use it to dissolve the D into it.
I use Bio-D Mulsion by Biotics Research Corp.
and I think this is the best out there each drop is 2000 IU's I do 6 drops a day. Some say if you do 2 drops at bedtime it helps you sleep.
Thanks Pmgamer18 and Eatingisfun for the info. That was helpful.
Bio-D Mulsion Forte by Biotics Research Corp.---->2000 IU
Bio-D Mulsion by Biotics Research Corp.---------->400 IU
You guys are taking heaps of vit D.
I got tested moderately low, I think 25 or something, I got prescribed 2000IU for the 1st month and 1000IU each day, its been about 3 months and getting follow ups soon, should have results in about a week.
On 6 drops or 24,000 IU's my labs were still under mid range on 7 drops I do great.
6 drops = 12.000 iu
Thanks it's been one of them days.
