- BEYOND CALCIUM — THE FULL BONE MATRIX: Real bone contains far more than calcium. Each serving delivers the complete matrix: calcium, phosphorus, and magnesium in natural ratios alongside collagen Types I & II, bone-specific peptides, and phospholipids — all working together the way they do in actual bone tissue. Isolated calcium gives you one compound. This gives you the matrix.
- COLLAGEN TYPES I & II FROM WHOLE BONE: Type I collagen supports connective tissue, skin elasticity, and tendon integrity. Type II supports cartilage and joint cushioning. Both are naturally present in whole bone and are absent from every mineral-only calcium supplement on the market.
- BONE MARROW — THE NUTRIENT FACTORY: Marrow is the site of blood cell production and contains growth factors, fat-soluble vitamins A and K2, and beneficial fatty acids. Traditional cultures cracked bones specifically to access it. Three capsules make that nourishment accessible daily without cooking or sourcing marrow bones.
- STACKING NOTE — SEPARATE FROM IRON SUPPLEMENTS BY 1–2 HOURS: Calcium competes with iron for absorption. If you take Beef Liver or IRONCLAD alongside Bone & Marrow, space them 1–2 hours apart to preserve full iron uptake. This is a real, well-documented nutrient interaction — worth managing, especially if iron is a priority.
- 5-STAGE TESTING — PUBLIC COA: Every batch tested five times across identity, in-process, finished product, heavy metals, and microbial safety. Results available on our product page. Sourced from 100% grass-fed, grass-finished cattle on regenerative pastures in New Zealand — recognized for some of the world's most stringent animal welfare and grazing standards.
