I live in the Himalayas of India and have been an author who seldom stepped out of the house and was clearly Vit D deficient. I had no blood tests done for Vit D all my life.

Since I was diagnosed with osteopenia and felt muscle fatigue and weakness all the time I decided to take Vit D on my own. No doctors here knew anything about Vit D dosing.

I began taking Vit D3 at 60,000 IU per week ( 8500 IU per day) for three months. And at the end I got my results just now in January 2010 through Grassroots.com who sent me a kit at home from the USA.

The results are 103 ng/ml

Their normal values show the range:

30 - 100 ng/ml

Even fifteen days before the results came I had reduced by dose to half, i.e. 30,000 IU per week ( 4300 IU per day) just to be on the safe side.

Now that I know that my levels at the start of Jan 2010 stood at 103 ng/ml, do I need to reduce or stop my Vit D3 intake for some time?

Is 103 ng/ml too high a level? I feel fine and energetic as before.

Can you tell me what I should do next?

Thanking you in anticipation,

You're doing perfectly

Hi Nathji,

Well, it's very likely that the calcium from all the milk you were drinking simply went right down the toilet.

I'm sorry to hear about your osteopenia, but it sounds like you are doing EXACTLY the right thing now. 60,000 IU's per week is an excellent Vitamin D Deficiency Treatment dose, and 30,000 IU's per week is almost exactly right to meet your daily Vitamin D Requirements.

I wouldn't worry too much about the 'high' vitamin d level. The normal levels on your lab sheet are from 30 to 100 ng/ml. And while the 'optimal levels' are a little bit lower than that, a level of 103 ng/ml has never been shown to cause any harm and it's still QUITE far from levels that cause Vitamin D Toxicity- which need to be AT LEAST 150 ng/ml and likely closer to 250 ng/ml.

And in fact, in certain disease states, like Multiple Sclerosis, researchers found that patients had the most benefit when their Vitamin D Levels were about 100 ng/ml. So, in some disease conditions, that high a level can even be beneficial.

So, now that you are at the 30,000 IU's per week, your numbers will gradually come down and will likely be right at the Optimal Vitamin D Levels soon. Just get your level rechecked in 2 to 3 months.

Thank you for writing in.

tests can be done in India

Well nathji,

I recently got tested and my result was 19.1 ng/mL, I got it done through an Indian provider called Thyrocare(+91-22-30903090),their business model is of blood collection points scattered all over india , blood samples are then sent to Bombay where tests are done and the results are emailed.

I believe they have collection center in Roorkee, Haridwar besides Delhi and their charge is also very nominal Rs 600($13). I would suggest get a complete blood profile done.

Their reference range was confusing (11.1 - 42.9 ng/mL). I contacted their inhouse physician and she told me the reference ranges are prescribed by the manufacturer of their test equipment, in this case Roche. However she acknowledged based on general consensus amongst experts/researchers the level should atleast be 35 ng/mL !

I would also suggest checking out Dr BK Roy who is endocrine specialist practicing in Delhi, I believe he does online consultation and is at least aware what 25 hydroxy test is all about !
