Calcium Citrate • Liposomal Magnesium • Vegan D3 • K2-7 • Superior Absorption
Not all calcium is created equal. While calcium carbonate requires stomach acid and causes constipation, Bonoxil uses calcium citrate which absorbs 24% better, works without food, and is gentle on your digestive system.
Calcium citrate demonstrates ~24% higher absorption than carbonate and does not require acidic environment for dissolution. Delivers 70-95mg systemic calcium vs 75-125mg from 500mg carbonate, with far superior tolerability.
| Parameter | Bonoxil (275mg Citrate) | Standard (500mg Carbonate) |
|---|---|---|
| Elemental Calcium | 275mg | 500mg (appears higher) |
| Absorption Rate | 25-35% | 15-25% |
| Systemic Delivery | ~70-95mg | ~75-125mg |
| Acid Dependency | ✓ No (works anytime) | ✗ Yes (needs stomach acid) |
| Constipation Risk | ✓ Low | ✗ Higher |
| GI Comfort | ✓ Better | ~ Less |
| Take With Food | ✓ Yes | ✗ No (empty stomach only) |
In real-world conditions—especially pregnancy, menopause, and low-acid states—275mg calcium citrate performs close to higher-dose carbonate while minimizing side effects.
24% better absorption than carbonate. No acid dependency. Gentle on stomach. Optimal for pregnancy and low-acid states.
30-40% absorption vs 4-15% from oxide. Phospholipid bilayer enhances cellular uptake. No GI irritation. Essential for bone matrix.
100% RDA. Enhances intestinal calcium absorption. Maintains optimal bone mineralization. Clean-label vegan source.
100% RDA. Activates osteocalcin to bind calcium into bone. Prevents arterial calcification. Long half-life ensures calcium goes to bones, not arteries.
Most calcium supplements only provide calcium. Bonoxil delivers the complete bone-building team: calcium for structure, magnesium for matrix, D3 for absorption, and K2-7 for proper placement.
28% RDA. 24% higher absorption than carbonate. Independent of stomach acid. Superior GI tolerability. Better for pregnancy and menopause.
6% RDA. Liposomal delivery achieves 30-40% absorption vs 4-15% for oxide. Would need 75-200mg oxide for similar systemic levels.
100% RDA. Cholecalciferol from vegan source. Enhances calcium absorption 10-15x. Critical for bone mineralization.
100% RDA. Long half-life (72 hours). Activates osteocalcin for bone binding. Prevents vascular calcification. Completes the calcium pathway.
Higher absorption = better bone density results with fewer side effects
High calcium needs without constipation. Citrate form safe and effective during pregnancy. Supports fetal bone development.
Declining estrogen affects bone density. K2-7 ensures calcium goes to bones, not arteries. Citrate works despite reduced stomach acid.
Age-related hypochlorhydria reduces carbonate absorption. Citrate works regardless of acid levels. Gentle on aging digestive systems.
Maintain peak bone mass. Liposomal magnesium supports muscle function and recovery alongside bone health.
Taking PPIs? Carbonate won't work. Citrate absorbs without acid. Perfect for those on acid-reducing medications.
Vegan D3 source. Complete bone support without animal-derived ingredients. Clean-label formulation.
