Core Four

Calcium isn't the problem. Where it ends up is.

Most indoor, screen-bound lives quietly run low on the nutrients that keep bones supported and energy steady. Not because you’re eating badly, but because sunlight, K2 and B12 are genuinely hard to get day to day. Calcium alone doesn’t fix it; calcium needs direction. Core Four covers the four that do the directing — in one tablet.

Products benefits
  • Bone support that goes beyond calcium alone
  • D3 absorbs calcium – K2 steers it into your bones
  • B12 for normal nerve function and energy upkeep
  • Magnesium to round out daily minerals – all in a single tablet
  • Vitamin D3 (Cholecalciferol) — a full day’s vitamin D (600 IU) for normal calcium absorption and bones.
  • Vitamin K2 (MK-7) — the long-acting K2 form that helps direct calcium into bone.
  • Vitamin B12 (Cyanocobalamin) — a stable, well-absorbed B12 form your body converts and uses.
  • Magnesium Sulphate — fully soluble, fast-releasing ionic magnesium — the classic mineral form.

Take 1 tablet in the morning, after breakfast. D3 and K2 are fat-soluble, so a meal with some fat helps absorption.

*Not intended to diagnose, treat, cure or prevent any disease.

Energy that doesn't quietly slip — the B12 your body runs on for normal energy metabolism, topped up day after day. Bones that keep their footing — steady D3 + K2 so your bones stay supported as the years add up, calcium going where it should. One small habit, fully covered — four nutrients in one daily tablet.

What These Nutrients Quietly Do Every Day

Vitamin D3 (Cholecalciferol)

The nutrient your body makes from sunlight and most indoor lifestyles don’t get enough of.

THE EVERYDAY ROLE → Helps your body absorb calcium and keeps bones and muscles working normally. 600 IU is a full day’s adequacy.

Vitamin K2 (MK-7)

The “traffic controller” for calcium, made by fermentation and scarce in modern diets.
THE EVERYDAY ROLE → Activates the proteins that direct calcium into bone where it belongs, rather than into soft tissue. MK-7 is the long-acting form.

Vitamin B12 (Cyanocobalamin)

The energy-and-nerve vitamin that’s hardest to get from a plant-based diet.
THE EVERYDAY ROLE → Supports normal energy metabolism, nerve signalling, and red blood cell formation — in a stable, well-absorbed form your body converts and uses.

Magnesium Sulphate

Fast-releasing magnesium your body
can put to work.

WHY IT’S QUICK → Fully water-soluble, so it dissociates readily into free magnesium ions – no complex to unpack, just the mineral itself, available fast.

Frequently asked questions

1. Who is Core Four for?

Adults looking to support everyday bone, nerve, and energy health — especially those 30+, with limited sun exposure, sedentary routines, or plant-based diets. It’s designed for daily nutritional maintenance, not to correct a diagnosed deficiency.

One tablet daily, in the morning after breakfast. D3 and K2 are fat-soluble, so taking it with a meal that contains some fat helps absorption.
They work as a pair. D3 helps your body absorb calcium; K2 (MK-7) helps direct that calcium into bone rather than soft tissue. Taken together, they support the calcium pathway more completely than D3 alone.
No. Core Four supports how your body uses calcium; it doesn’t supply a meaningful dose of calcium itself. It’s meant to complement a calcium-adequate diet, not replace dietary calcium.
Yes — all four nutrients are at daily, RDA-level amounts well within established safe intake ranges. As with any supplement, don’t exceed the recommended dose.
It’s a fully water-soluble, fast-releasing form — it dissociates readily into free magnesium ions your body can put to work, with no complex to unpack. It’s included to round out your daily mineral intake.

Generally it pairs fine with most daily supplements. But if you take blood-thinning medication (Vitamin K can interact with it), or any prescription medicine, check with your doctor or pharmacist first.

Nutritional needs change during pregnancy and breastfeeding, so please consult your doctor before starting any supplement.
30 tablets — a full month at one tablet a day.
In a cool, dry place below 25°C, away from direct sunlight, with the cap closed tight. Keep out of reach of children.
