Analysis updated August 2026 · How Scout scores
At a glance
Summary
This supplement contains beneficial methyl B-12, which supports brain and nerve health, but includes natural flavor, which lacks transparency and could potentially include undisclosed additives. The presence of dextrose as a filler is a minor concern, though it is not a major red flag. Overall, the formulation is relatively clean with minimal processing, but the inclusion of natural flavor and fillers slightly impacts its score.
