Filed label facet · NIH DSLD snapshot 2026-08-10
2 labels, 2 brands, one filed formulation (400 mg × 1)
2 labels from 2 brands file the same formulation in NIH DSLD snapshot 2026-08-10: 4 other ingredients, 1 unit per serving and 400 mg of elemental magnesium per unit. Fewer than two priced labels share a salt here as of 2026-11-02, so no spread is computed. The labels do not name who makes them.
