Does Vitamin D Thin Blood
Vitamin D3 is a fat: soluble vitamin and is best absorbed when eating fats & if you are not fat/obese. If you have a bleeding ulcer it does not thin the blood further, and possibly isn't even being absorbed if you are not eating, because of a bleeding ulcer.If a person is obese/fat, it gets sequestered or stored in the fat, and not absorbed either.It is not known to have that type of relationship to bleeding ulcers. ...Read moreSee 2 more doctor answers
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
I have a blood test tmrw afternoon to check my vitamin d. When do you have to fast for a blood test? I don't have to right? I forgot to ask. Thanks.
Not necessary but...: No, you do not have to fast for this test, but it is wise to not eat much within a couple of hours of any blood test as shortly after a meal your blood will be loaded with triglycerides which reduces the amount of serum available for testing. So i advise either eating a light lunch or waiting about 3 hours after eating- but that is not absolutely essential. ...Read more
Athlete. 112 lbs. Took 50000iu/day vitamin d for 3 months but 25-oh d blood test still normal. How is this possible? Is it bc i move alot/use up more
Blood result showed that I was deficient of vitamin D. I scored half of what a normal level is.Type of vitamin D should I take and how much (IU) a day?
5-10,000 iu D3/day: With levels that low I advise you start by taking 10,000 iu of D3 a day for 2 months, then reduce to 5-8000 iu/day. At some point you should recheck your levels. Optimal levels are 50-80. It is best to take Vitamin K along with D and make sure you are getting Vit A as these vitamins work synergistically. Avoid D2, which is dangerous!

Blood test came back low vitamin d. Dr recommends 2000 iu daily 50000 iu weekly. Does that seem excessive? Could low vit d be caused by deposit shot?
Safe: Use d3 as it is better absorbed and safer than d2. I routinely dose 5000 iu daily. Just recheck vit d levels in 2-3 months and adjust intake accordingly. Aim for serum level close to 60. ...Read more

No: A high B12 means nothing. If you have a low B12, you need to asking, "Why is it low?" and "What do I do to correct the situation before I end up with permanent brain damage?" If you're a non-supplementing vegetarian, please re-examine your choices. If there is any possibility you have pernicious anemia or another absorption problem, get worked up and treated. ...Read more
