It contains the oolate form which has the best absorption rate of calcium, and it is ordered and fed for 6 years old. In the 15th millitorium, calcium 250 contains vitamin d 3 and magnesium 100. It feeds 30 millitories. This product is included. Orotate-containing type, which is the best type in terms of absorption rate, is only for this product. I have to order 2 bottles per month, which is a little inconvenient.
