MINERAL ASSIMILATION is affected by pH. Minerals have different pH levels at which they can be assimilated into the body. Minerals on the lower end of the atomic scale can be assimilated in a wider pH range, and minerals higher up on the scale require a narrower and narrower pH range in order to be assimilated by the body. For example….
Sodium and magnesium have wide pH assimilation ranges.
It narrows somewhat for calcium and potassium.
Narrows more for manganese and iron.
More for zinc and copper.
More for iodine.
