What Are the Side Effects of NBI Osteo-K?
Always consult your health practitioner if in doubt.
RiskLow Risk
Overview
•Vitamin K2 (MK4) at 45 mg/day is well-tolerated with minimal side effects like mild GI upset, but contraindicated with anticoagulants like warfarin due to clotting interference.
•Calcium citrate 1000 mg/day is within safe limits (UL 2500 mg) but may cause constipation or bloating if total intake exceeds needs; monitor in kidney disease patients.
•Vitamin D3 2000 IU/day is safe and below UL (4000 IU), supporting bone health without hypercalcemia risk in healthy adults.
•Suitable for pregnancy under medical supervision, as calcium and vitamin D aid maternal health, but vitamin K2 requires caution with consistent intake to avoid clotting issues.
•No major allergens; veggie capsules avoid gelatin sensitivity, but rice flour may concern those with rare rice allergies.
•Long-term use supported by trials up to 8 years without serious adverse effects, though periodic monitoring of calcium levels recommended for high-risk groups.
