The probiotics produce short-chain fatty acids (especially lactic and acetic acid) that lower intestinal pH, converting insoluble mineral salts into easily absorbable ionic forms. L. acidophilus further produces phytase, which breaks down phytic acid - the main dietary blocker of mineral absorption- significantly increasing the pool of bioavailable Ca, Mg, and Fe.

Lorbiotics Ostio D3
Stronger bones start with better absorption. The probiotic component actively enhances your body's ability to absorb and retain the minerals your bones need.

Up to 40% increase in active calcium absorption with Vitamin D3 1000 IU via TRPV6 upregulation — combined with L. reuteri osteoclast suppression for comprehensive bone protection.
Why Ostio D3 works.
“Unlock Stronger, Healthier Bones Naturally – The Ultimate Microbiome + Collagen Power Trio”
Lorpro-OstioD3 is a specialised bone-health synbiotic that combines four clinically selected probiotic strains - Bifidobacterium lactis, Bifidobacterium longum, Lactobacillus acidophilus, and Lactobacillus reuteri - with Vitamins C and D3 to optimise the absorption and bioavailability of calcium (Ca), magnesium (Mg), and iron (Fe).
- 01Calcium absorption enhancement
- 02Magnesium & iron bioavailability
- 03Bone density protection
- 04Postmenopausal bone health
- 05Bone matrix quality
- 06Comprehensive mineral status improvement

Lorbiotics Ostio D3 · Bone Health
How it works, step by step.
The documented biological pathway — exactly how each component acts inside the body.
Vitamin D3 (cholecalciferol) enhances this by upregulating key calcium transporters (TRPV6) and binding proteins (calbindin-D9k/D28k) in the intestine, boosting active calcium absorption by up to 40%. Together, the probiotic–vitamin synergy delivers superior mineral uptake compared to either component alone.
Ideal for: Individuals at risk of osteopenia, osteoporosis, or mineral deficiency across all ages.
Lactobacillus reuteri is a game-changer for bone health. It doesn’t just help with calcium absorption - it delivers direct bone-building power.
This superstar strain actively suppresses bone-destroying osteoclasts by boosting protective IL-10 and reducing inflammatory TNF-α in bone marrow.
Backed by clinical trials, L. reuteri has been proven to significantly slow age-related bone loss in postmenopausal women - delivering real, measurable results through a powerful microbiome-bone connection.
Bifidobacterium longum helps restore hormonal balance where it matters most. By producing key enzymes (β-glucuronidase and β-galactosidase), it supports the natural recycling of estrogen in the body - fighting the rapid bone loss that hits after menopause when estrogen levels drop.
Vitamin C supercharges bone strength from within. As an essential cofactor for collagen synthesis, it builds the strong, flexible protein framework that gives your bones quality and resilience - so every bit of calcium you absorb turns into rock-solid, high-quality bone.
Every ingredient earns its place.
