Question: Hi Dr. Manhart – I’m using the calcium granules with success. just wanted to clarify some things. If the granules turn gray, are they still safe to use? Can i use the granules repeatedly as long as there are in the bottle? – Thanks, L.L. NY
Answer: As long as there are granules in the bottle it is good to use. The color will fade, but the concentration is still high with the granules in the bottle. Each order of the bottle or the refill will make 4 bottles of solution, 32oz.
