Side Effects
It has been suggested by some authorities that milk is not a good source of calcium to rely on, partly because of the commonness of allergic reactions and also because it lacks Magnesium, which can lead to a magnesium deficiency, especially in children drinking large quantities. It is usually not toxic in healthy persons. Do not give at the same time of day as magnesium and Manganese. Ensure stomach acidity is satisfactory.

Important Notes
Dosages advised are deliberately on the safe side and may not be high enough to give benefit, but it is recommended that higher dosages should only be taken under the care of a practitioner experienced in nutritional medicine.

Side Effects refer to effects of much larger doses on the whole than those recommended here.
