What Does Cal/Mag/Vit D3 with Vitamin K2 Do?
A straightforward bone-support formula with calcium, magnesium, vitamin D3, and K2 in clearly labeled doses. The main formulation caveat is the use of magnesium oxide, which is a less absorbable magnesium form.
Is this formula suitable if I'm taking a calcium supplement already?
How does the magnesium oxide in this product compare to other magnesium forms?
Can I take this with vitamin K2 if I'm on blood thinners?

Overview
•Vitamin K2 can interfere with warfarin and other anticoagulants; this product should not be used without clinician guidance if you take blood thinners.
•Calcium and magnesium can cause constipation, bloating, or loose stools depending on sensitivity and total daily intake.
•The magnesium form is magnesium oxide, which is less well absorbed than citrate or glycinate and may be more likely to upset the stomach at higher intakes.
•Pregnancy and breastfeeding safety is not clearly established for this combination at this dose; medical advice is recommended before use.
•No major food allergens are obvious from the label, but the formula contains rice-derived ingredients and may not suit those avoiding rice-based excipients.
•Total calcium intake from diet plus supplements should be monitored to avoid excessive intake, especially if you have kidney stones or kidney disease.
