What could be causing low vitamin d even with normal calcium levels?

Too little intake: The body maintains stores of vitamin d in the fat cells. It takes a long time for a deficiency to develop, and a long time to correct it using typical over-the-counter supplements. People normally get vitamin d from sun exposure and a few food sources (liver, eggs) as people have moved indoors and don't eat as much eggs & liver, vitamin d deficiency has become more common. ...Read more

many possiblities: While hyperparathyroidism is by far the most common cause of elevated serum calcium, there are many other possible causes.

Is it important to monitor vitamin d levels annually if my calcium levels are normal?  Only my vitamin d was low (>15).  My doc says it's not import

It is important: It is important to try to mantain a vit d level of greater than 50ng/ml many docs do not see this as important but this is gradually changing/improving check vit d levels about every 3-4 months until a steady state is achieved and then about once per year dose is about 1000iu vitd per each 25# of body wt therefore a 100# person would use 4000iu/day. ...Read more

Could a severe vitamin d deficiency mask primary hyperparathyroidism by lowering serum calcium levels? [would u see low-normal calcium and high pth?]

Could a severe vitamin d deficiency mask primary hyperparathyroidism by lowering serum calcium levels? [would u see low-normal calcium and high pth?]

Primary hyperpara: Low vit d is common in patients with primary hyperparathyroidism. Although it is possible that it can mask the hypercalcemia, usually it does not. If your d is low, and you have hyperpara, you will likely still have a high ca. The low d may make the PTH level even higher, and vit d supplements should be given and they will not exacerbate the high calcium. This is complex. See endocrinologist. ...Read more

Take the D: You need at least 2000 units of vitamin d3/day and recheck your levels in 3 mos. Or so. They are not dangerous, but need to be improved. Also make sure your thyroid level is normal and that you are receiving brand name T4 replacement, as the generics are unreliable. ...Read more

I get kidney stones but I am also very low on active vitamin d. Will taking active vitamin d cause an increase in calcium thus more stones?

I get kidney stones but I am also very low on active vitamin d. Will taking active vitamin d cause an increase in calcium thus more stones?

D3 and stones: Vitamin D3, when activated by the liver and kidney, does enhance calcium absorption across the intestine. So, your kidney's excretion of calcium may increase. It is essential to know why you form stones. The standard prevention is high intake of citrate and fluids - get citrate from ReaLemon extract, 5 tblspn / day - and drink 4 liters fluid per day, avoid salt, reduce meat. Add 1000 IU D3/day. ...Read more

Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine. ...Read more
