My 11 year old daughter (weight 35 kgs and overall healthy) was found to be deficient in Vitamin D (25 OH level of 9.5 ng/ml, although she had no symptoms of any Vitamin D deficiency) around 9 months back and as per the recommendation of her pediatric, we gave her Vitamin D3 supplement for 2 months (we gave her 60,000 units supplement, I think 6-7 times) while resulted in her levels shooting up to 65 ng/ml. After this as per the advice of her pediatric we stopped with the supplements for the last 7 months. However, we do give her multiivitamins on alternate days which provides her 5 mcg of Vitamin D. My questions is whether 5 mcg of Vitamin D on alternate days is sufficient for her, going forward as a maintenance dose? We live in India and her exposure to sunliight is moderate.Also is 65 ng/litre very high for her and was such a rapid increase from 9.5 ng/ml to 65 ng/ml in a span of 2 months would have harmed her in anyways that we yet dont know about?
Thanks in advance for your revert.
