Overview
•High 10,000 IU Vitamin D dose is effective but may cause hypercalcemia in sensitive individuals or long-term use without monitoring; safe for most adults per NIH guidelines when under 4,000 IU daily upper limit is considered, but this exceeds it.
•Vitamin K2 (100 mcg) and D3 synergy reduces arterial calcification risk, but K2 may interact with blood thinners like warfarin, requiring physician consultation.
•Low doses of B6 (3.4 mg), magnesium (25 mg), and zinc (10 mg) are well within safe limits (ULs: B6 100 mg, Mg 350 mg supplemental, Zn 40 mg) with minimal side effects.
•Ox bile (5 mg) and MCT powder (20 mg) aid absorption but may cause mild GI upset in those with gallbladder issues or bile sensitivities.
•Not recommended for pregnant/nursing women, children under 18, or those with kidney disease without medical advice due to high Vitamin D and potential hypercalcemia risks.
•No major contaminants reported for Dr. Berg products; vegetable capsule is vegan-friendly with low allergen risk.
