Can it be taken with other supplements or vitamins?
Can it be taken with other supplements or vitamins?
Yes — D3 and K2 work synergistically and are safe to combine with magnesium, calcium, or a daily multivitamin. Avoid double-dosing K2 if your multivitamin already contains it.
Are there any specific instructions for taking it safely?
