Vitamin D3 + K2 supplement manufacturing

Fat-soluble micro-doses — delivery and uniformity done right.

Vitamin D3 and K2 are fat-soluble vitamins dosed in micrograms, so two things define the product: a fat-based delivery system that carries and absorbs them, and precise uniformity of a very small active load. HBM manufactures D3/K2 as oil-based liquid drops and as gummies, protecting the MK-7 form of K2 and validating dose uniformity, in Tampa Bay, FL.

Fat-soluble means fat-based delivery

D3 (cholecalciferol) and K2 (menaquinone) are absorbed with fat, so the cleanest delivery is an oil base — an MCT or similar oil for liquid drops, or a gummy formulated to carry the oil-borne actives. HBM builds the delivery system around that chemistry rather than forcing a fat-soluble vitamin into a purely water-based format.

Micro-dose uniformity and MK-7 stability

Doses are tiny — D3 around 1,000–5,000 IU (25–125 mcg) and K2 around 90–180 mcg — so, as with any low-dose active, even distribution is the whole game. The MK-7 form of K2 is also sensitive to certain minerals and pH, so HBM keeps incompatible components apart in the formula and confirms both potency and uniformity by testing.

Formats and combinations

D3 is often paired with K2 (which supports where calcium is directed), and sometimes with a base oil for absorption. HBM makes it as a liquid dropper or a gummy, at a liquid MOQ of 3,000 units or 150 liters and a gummy MOQ of 300,000 units.

FAQ

Why are D3 and K2 made in an oil base?

They are fat-soluble, so a fat-based delivery — an MCT or similar oil — carries and helps absorb them better than a purely water-based format.

Are D3 and K2 doses hard to hit accurately?

They are micro-doses, so even distribution is the whole challenge; HBM validates content uniformity by testing rather than assuming it.

Why combine D3 with K2?

K2 is commonly paired with D3 in a single product; HBM formulates the combination as a liquid dropper or a gummy while protecting the sensitive MK-7 form of K2.
