Natrum phosphonic is used as a Homeopathic medicine (cell salt). Homeopathic potencies accredit their strength and efficacy to the electromagnetic signatures of the original substrate; these are scientifically created dilutions and succussions of medicines such that generally not even a molecule of the original substrate or medicine is present in the medicine.

As a Homeopathic or used simply as a micro-nutritional, Natrum phosphonic has demonstrated effectiveness against the following symptomology: "Natrum phos. is the remedy for conditions arising from excess of lactic acid often resulting from too much sugar." (Boericke) -"Natrum phos. also serves to saponify fatty acids; it therefore cures those ailments which arise from eating fatty food or which are aggravated thereby." (Clarke) -ill-effects from abuse of sugar (Boericke).
