Calcarea Phosphorica 6X: Growing Pains, Not Calcium

Dr. Dheeraj Sharma BHMS (Kanpur) Published August 26, 2026 Updated September 18, 2026

Calcarea phosphorica 6X is the biochemic and homeopathic preparation of calcium phosphate, Schüssler’s tissue salt No. 2. It is classically used for slow dentition, growing-pain pictures, school-age headaches at the sutures, and a thin, dissatisfied child who wants ham and smoked meat. A 6X tablet still contains a tiny, weighable amount of mineral — not a therapeutic calcium dose. It does not treat rickets, osteoporosis or a low 25-OH vitamin D. Do not swap a prescribed calcium or vitamin D course for Calc phos.

This article is for people searching calcarea phosphorica 6x uses, Calc phos 12X, or Calcarea phosphorica 30. It is not a growth-hormone protocol, a fracture-union drug, or infant formula.

Calcarea phosphorica at a glance

What Calcarea phosphorica is — and what it is not

Calcium phosphate is the mineral of bone and teeth. Boericke: tardy dentition and the troubles of that period; non-union of fractures as a classical claim; anaemic, peevish, flabby children with cold extremities and feeble digestion; symptoms worse from any change of weather; numbness and crawling.

One labelled 6X pellet declares on the order of 0.443 mg of “active” per pellet at 6X — that is still a homeopathic quantity, not a 500 mg calcium carbonate tablet.

It is not a nutritional calcium supplement, a vitamin D analogue, or a treatment for vitamin D deficiency. The old page listed calcium fluoride, magnesium phosphate and sodium phosphate as “constituents” of Calc phos. Those are other tissue salts, not ingredients of this bottle. See the biochemic tissue salts guide.

The dilution arithmetic

• 6X is one part in a million. It is not “nothing,” and it is not a dietary dose.
• 12X is a thousand-fold smaller still.
• 30C is past the point where a molecule of the original salt is expected. It is a different product from 6X even though both say “Calcarea phosphorica.”

People search calcarea phosphorica 6x and calcarea phosphorica 30 as if they were strengths of the same pill. They are different manufacturing ideas. 6X is the biochemic tablet habit (several tablets, several times a day, in the Schüssler tradition). 30C is a short homeopathic dose, then stop.

What the evidence actually says

There is no reliable trial that Calc phos 6X increases bone mineral density, closes a fontanelle, heals a fracture, treats anaemia, or raises serum calcium. For confirmed vitamin D deficiency use IU of D2 or D3, then maintenance — not tissue salts. For dietary calcium, food and, when a clinician advises it, milligram-dose calcium salts are the tools. Rickets is a paediatric emergency of mineralisation, not a 6X gap.

What Calc phos is classically used for

Teeth and growth. Slow teething with delayed, difficult teeth; school-age “growing pains” in the legs; headaches in children around the cranial sutures, worse with weather change. Complementary classically to Ruta and compared with Calcarea carbonica (the chilly, sweaty, plump Calc carb child versus the thinner, discontented Calc phos child).

School and study. Headache in school children; wants to wander; dissatisfied. This is not ADHD care — see ADHD.

Recovery pictures. After acute illness, a child who does not pick up; bone-pain pictures. Non-union of a fracture is an orthopaedic problem. Do not sit on Calc phos instead of a repeat X-ray.

Craving. Smoked meat, ham, bacon — a Boericke food note, not a diet plan.

Calc phos 6X vs 12X vs 30C

OTC 6X directions vary (five pellets three times daily on one label; chewable acute dosing every 30 minutes up to six times on another). We do not invent a milligram calcium schedule. If you use 6X at all, treat it as a short matching course, not a year of “bone support.”

How to take Calcarea phosphorica 6X

• Dissolve or chew as the label says; clean mouth.
• Biochemic habit is frequent small doses while the picture is there, then stop.
• Do not combine five tissue salts because a chart said “bones.” One salt, or none.
• Infants: teething is not a reason to skip a fever work-up. Do not pack 6X into a bottle of milk.
• Pregnancy: 6X is a microdose of phosphate in lactose; unstudied as obstetrics. Prenatal calcium and vitamin D come from the obstetric list, not Schüssler.

Side effects

6X / 12X. Realistic issues: lactose bloating in the intolerant; sugar load if someone is grazing on tablets all day; a brief sharpening of the pictured complaint. The fluoride, kidney-stone and “too much calcium” warnings copied between blogs do not survive the microgram arithmetic — this salt is phosphate of lime, and the mass is tiny. See homeopathy side effects.

30C / 200C. Vehicle only. No calcium loading.

What is not a side effect of 6X: correcting or causing osteoporosis. The harm is delay of vitamin D, DEXA, or paediatric growth assessment.

Calc phos compared with nearby remedies

When to see a doctor

• a child not gaining length or weight; delayed walking; bowed legs — rickets / endocrine work-up
• a fracture that is not uniting
• bone pain at night, a lump, or unexplained bruising
• a low 25-OH vitamin D or low serum calcium — replace with real IU / milligrams
• tetany, spasms, or a seizure
