Cal-M is a capsule which supplies calcium and magnesium as acetates, with organic cider vinegar to create the optimum acidity. Cider vinegar manifests as an alkaline precipitate in the body and has many medicinal values of it's own. Pre-mixed and dried, it also provides traces of potassium, phosphorous, zinc and iron. Muscular spasms can be caused by calcium deficiencies. Nervous reactions can be diminished by magnesium. However, these minerals are not well absorbed unless supplied in an acidic form. Cal-M supplies calcium and magnesium along with organic cider vinegar to create that optimum acidity, allowing for far greater absorption than taking calcium and magnesium through other means. Suggested Uses: Athletes after exercise, Half an hour before bed, Convalescents, twice or more daily, During pregnancy, daily, Teething babies 1/4tsp daily and As needed to aid relaxation Cal-M also provides traces of potassium, phosphorous, zinc and iron.
