BIOGENA Osteo Calbon Komplex Gold

Rating breakdown

Evidence for ingredient 8.0/10

Calcium + D3 + K2 is the most evidence-backed bone stack. Hydroxyapatite also provides phosphorus. Silicon and boron have supplementary evidence.

Value for money 5.0/10

€1.33 per day is premium pricing. Equivalent single supplements cost less combined, but the convenience of one product has value.

Product Description

BIOGENA Osteo Calbon Komplex Gold combines six bone-relevant actives in one product. The centerpiece is Calbon-N — microcrystalline hydroxyapatite from natural sources, delivering calcium and phosphorus in the natural ratio (as found in bone itself). Complemented by coral calcium, vitamin D3, K2 as K2VITAL (all-trans MK-7), silicon from bamboo shoot extract, and boron.

What We Like

Hydroxyapatite instead of isolated calcium carbonate — delivers calcium + phosphorus in the natural ratio
K2VITAL (all-trans MK-7) — the most effective K2 form
750 mg calcium per daily dose — clinically relevant amount
Silicon from bamboo (52 mg) + boron (3 mg) — often overlooked bone cofactors
Biogena pharmaceutical quality from Austria
Smart combination: D3 for calcium absorption, K2 to direct calcium into bones instead of arteries

What We’re Missing

3 capsules per day — a lot to swallow
€1.33/day is the highest price in our bone segment
90 capsules = only 1 month supply
No magnesium included (a commonly recommended bone cofactor)
Hydroxyapatite has fewer absorption studies than calcium citrate
