Bone Density
Strains with DEXA-validated bone-density benefits — the same measure your doctor uses.
Bones & Joints · 2 formulasClinical DomainBone Health
Stiff knees, aching joints? Stronger bones, easier movement.
Morning stiffness, nagging joints, quiet worries about bone density as the years add up — strength and mobility are worth protecting early. How much calcium you absorb and how much inflammation reaches your joints both trace back to the gut.

What this domain supports
The everyday wins of a balanced gut.
Joint Comfort
Dampen the inflammatory cytokines that drive joint pain, stiffness, and cartilage wear.
Calcium Absorption
Improve how efficiently the gut absorbs the calcium you already eat, before adding more supplements.
Mobility Support
Protect the gut–muscle axis that supports strength, balance, and ease of movement as you age.
Vitamin D Synergy
D3 paired with the strains to complete the absorption pathway calcium alone can't activate.
How probiotics actually help
Strength starts with absorption. Three levers, one blend.
Ostio D3 pairs four strains with Vitamin D3 and C for the gut–calcium axis.
01
Poor calcium uptake
L. reuteri 6475 improves how efficiently the gut absorbs calcium — and has shown bone-density benefits in DEXA-tracked trials.
L. reuteri 647502
Joint inflammation
L. casei dampens the inflammatory cytokines that drive joint pain and cartilage wear.
L. casei03
Low vitamin D
Calcium is useless without D3 to escort it. We pair the strains with Vitamin D3 to complete the absorption pathway.
