CALCIUM MANAGEMENT · EXPLAINED
Follow calcium from intake to normal bone support
Calcium, Vitamin D3 and Vitamin K2 act at different points. Combining them helps explain a coordinated bone-health routine, but it must not be presented as disease treatment.
01 · SUPPLY
Supply calcium
Calcium is a structural mineral in bones and teeth and must come from food or an appropriate supplementary source.
02 · ABSORB
Support absorption
Vitamin D promotes calcium absorption in the gut and helps maintain calcium and phosphate levels needed for normal bone mineralization.
03 · SUPPORT
Support bone proteins
Vitamin K2 is a form of vitamin K involved in proteins that take part in normal bone metabolism and maintenance.
WHY THE COMBINATION
Why these nutrients are often combined
Adds a key mineral
Helps increase calcium intake when the diet may be insufficient, while absorption still depends on several factors.
Adds the absorption step
D3 promotes intestinal calcium absorption, making this a directly relevant pair for bone nutrition.
Adds vitamin K-dependent proteins
Adds vitamin K's role in bone-related proteins. Evidence should not be overstated as prevention or treatment of osteoporosis or vascular disease.
WHEN INTAKE IS INADEQUATE
What inadequate status can mean
Inadequate calcium
Over time, the body may draw calcium from bone, contributing to loss of bone strength and a higher risk of osteoporosis.
Inadequate Vitamin D
Calcium absorption falls. Severe deficiency is associated with rickets in children and osteomalacia in adolescents and adults.
Inadequate Vitamin K
Clinically significant deficiency is rare in healthy adults, but it affects blood clotting and may affect bone-related proteins.
CHILD GROWTH · FACT CHECK
Children's height: keep the claim in context
Calcium and Vitamin D support normal bone formation and growth, especially when a deficiency is corrected. They do not make a child taller than genetic potential. Overall diet, protein, sleep, activity, health and developmental stage all matter.
This is general education only. The BONAVIE label states that children and pregnant women should not take this product.RESEARCH CONTEXT · RANDOMIZED CONTROLLED TRIAL
Independent research on Vitamin D3 + K2 in adults with Long COVID
A randomized controlled trial followed 151 adults for 24 weeks and compared Vitamin D3 plus Vitamin K2 with standard care.

Findings reported by the paper
- 25(OH)D increased in the D3 + K2 group and remained elevated through week 24.
- Long-COVID symptom scores and symptom counts changed more favorably than with standard care.
- The authors call for larger and longer studies to confirm the preliminary findings.
