BONE & CALCIUM

Bone Health Supplement Manufacturing — Calcium, D3 and K2 Done Right

Bone formulas only work when calcium, vitamin D3 and vitamin K2 are dosed together and against each other. We manufacture bone-health lines on our partner lines in Zhengzhou — from single calcium plus D3 products to full D3, K2, magnesium and collagen stacks.

Calcium, vitamin D3, vitamin K2 (MK-7), magnesium and boron combinations
Tablet, capsule, softgel and powder formats
D3 and K2 co-formulated to the ratio your label specifies

Calcium, vitamin D3 and vitamin K2 formulas in tablet, capsule, softgel and powder formats — built to a dose and a ratio you can defend.

Why Bone Formulas Are a Ratio Problem

Calcium needs vitamin D to be absorbed, and vitamin K2 (as MK-7) to direct that calcium into bone rather than soft tissue. That makes bone health a ratio problem first and a dosing problem second. A calcium-only product, or a D3 dose that does not match the calcium load, under-delivers against its own label.

The second constraint is physical. Calcium carbonate is bulky — a clinically meaningful dose of elemental calcium does not fit a small tablet, so honest formats are larger tablets, two-a-day units, or powders. Buyers who insist on a tiny single unit end up under-dosing.

Bone Health Product Lines: Pick Your Route

Bone health is a ratio problem — calcium alone does nothing without D3 and K2. Pick the route before you lock the ratio.

D3+K2 Route — Vitamin D3 + K2

The absorption route — the pair that makes calcium work. Softgel or drop, strong in EU and North America.

Mineral Route — Magnesium

The bone-density support route. Tablet or powder, broad ageing demographic, pairs with D3.

Calcium Route — Calcium + D3

The classic bone route for seniors and women. Tablet-led, high daily dose, the volume play.

Formats We Run for This Category

Tablets — the standard for calcium, D3 and K2 combinations, allowing a multi-gram daily dose across two units
Softgels — for vitamin D3 and K2 in an oil carrier, protecting the fat-soluble vitamins
Hard capsules — for magnesium, boron and smaller mineral blends
Powder and sachets — for high elemental-calcium loads and senior-friendly drink formats
Gummies — for a consumer-friendly calcium and D3 product with a lower dose ceiling

Actives We Already Work With

Calcium carbonate and calcium citrate, vitamin D3 (cholecalciferol), vitamin K2 as MK-7 (menaquinone-7), magnesium (citrate, glycinate, oxide), boron, hydrolysed collagen peptides, and trace minerals including zinc and manganese.

Frequently Asked Questions

What is the right calcium-to-D3 ratio?

There is no single universal ratio, but calcium is typically paired with 400–800 IU (10–20 mcg) of D3 per serving, depending on the target market and the calcium load. We confirm the ratio against your label before pricing.

Do you use MK-7 or MK-4 for vitamin K2?

Both are available, but MK-7 is the usual choice for bone positioning because it has a longer half-life. We confirm the form and the microgram dose against your claim.

Can you make a vegan calcium and D3 product?

Yes. Vegan D3 comes from lichen rather than lanolin, and calcium can be sourced as citrate rather than carbonate. Both affect cost and are confirmed at quotation stage.

Why can’t a full calcium stack fit a one-a-day tablet?

Calcium carbonate is bulky — a meaningful elemental-calcium dose needs roughly 1.2–1.5 g of the salt, which does not fit a small tablet. Honest formats are larger tablets, two-a-day units, or powders.
