Taking a multivitamin alongside this formula is common — worth understanding what to actually check before combining the two, especially given the disclosed Vitamin B12 here.
Compare both labels for overlapping Vitamin B12 content, since a typical daily multivitamin already includes it alongside this formula's own B12 dose.
Since Vitamin B12 contributes to brain energy and nervous-system function, checking your total daily intake across all supplements is worth doing carefully, not just estimating — mention both to your doctor if you take blood-thinning medication.
