Your quote: The minerals of the alkaline reserve are sodium, calcium, potassium, and magnesium – these must come from plants!
Answer: What about Manganse, Zinc, Copper, Cobalt, and all of the rest of the Trace Alkaline Minerals ?
What does a person do when the plant foods they are eating do not contain these in them, like Calcium in enough quanity ?
It may be better to say these would be better if they would come from a plant source !
This is "WHY" the Moreless Protocol, using the Lime water to help supply Calcium and the BSM to supply Live Carbohydrates and lots of Alkaline Minerals and Kelp to supply "ALL" of the other Alkaline Minerals !
