Why we made it
Taking calcium on its own is close to pointless. Calcium needs calcitriol — the active form of vitamin D — to be absorbed from the gut, and it needs Vitamin K to be directed into bone rather than deposited in soft tissue and arteries. Magnesium is required for the enzymes that handle it. Miss those and most of a calcium tablet simply passes through.
Calcin-K27 is built around that dependency chain. Each soft gelatin capsule carries 500 mg of calcium carbonate with calcitriol 0.25 mcg, Vitamin K27 45 mcg, elemental magnesium 50 mg and elemental zinc 7.5 mg, plus methylcobalamin 1500 mcg and L-methyl folate 800 mcg for nerve and homocysteine support.
The softgel format matters too: a liquid-filled capsule disperses faster than a compressed chalk tablet and avoids the constipation that makes people abandon calcium supplements.
Uses
The difference
Four things you can check on any competing label before you decide.
Calcitriol is the biologically active form of vitamin D — the body does not have to convert it through the liver and kidney first. That matters most in exactly the older patients who need calcium supplementation.
Calcium absorbed without vitamin K can end up in arteries and soft tissue rather than bone. Including K27 is what turns absorption into deposition.
A significant share of the population carries MTHFR variants that impair conversion of ordinary folic acid. L-methyl folate skips that step entirely.
Compressed calcium tablets are large, gritty and constipating. A liquid-filled soft gelatin capsule disperses faster and is far easier to keep taking.
Specification
The full quantitative breakdown, so you can compare us against anything else on the shelf.
Each soft gelatin capsule contains: Calcium Carbonate IP 500 mg, Calcitriol IP 0.25 mcg, Zinc Sulphate Monohydrate IP equivalent to Elemental Zinc 7.5 mg, Magnesium Sulphate IP equivalent to Elemental Magnesium 50 mg, Vitamin K27 45 mcg, Methylcobalamin IP 1500 mcg, L-Methyl Folate 800 mcg, Excipients q.s.
Take 1 capsule daily after a meal with water, or as directed by your healthcare practitioner. Do not take at the same time as an iron supplement or thyroid medication — space them at least two hours apart.
Consult your doctor before use if you have kidney stones, hypercalcaemia, or kidney disease, or if you take digoxin, thiazide diuretics or thyroid medication. Contains calcitriol — do not combine with another active vitamin D analogue without medical supervision. Not for children except on medical advice.
Questions
Calcitriol is the already-active form. The body normally has to convert D3 through the liver and then the kidney, and that conversion becomes less reliable with age or kidney impairment.
It directs absorbed calcium into bone rather than letting it deposit in soft tissue and arteries. Calcium without vitamin K is absorbed but not necessarily well placed.
It is a softgel rather than a compressed tablet, which disperses faster and is generally easier on the gut. The magnesium content also helps.
Not at the same time — calcium blocks iron absorption. Leave at least two hours between them.
