calcium carbonate

How this group is counted

20 distinct NIH DSLD identifiers enter this group once each, using the 2026-08-10 snapshot and normalization dated 2026-09-13; multiple spellings on one label do not multiply its count.

Case and repeated spaces are normalized. Silica and silicon dioxide share one facet; hypromellose, HPMC and hydroxypropyl methylcellulose share another. Vegetable magnesium stearate joins magnesium stearate, and vegetable cellulose joins cellulose. Cellulose and microcrystalline cellulose remain distinct. Entries such as “none”, “coating” and “contains less than 2% of” are record markers rather than substance facets.

1 filed spellings feed this facet as of 2026-09-13:

• Calcium Carbonate

Salts and physical states

20 matching labels occupy 6 resolved-salt or unresolved groups and 4 physical-state groups, using NIH DSLD records classified 2026-09-13; each distribution totals 20.

Filed labels and observed prices

20 labels are listed below in brand and product order; 2 have a published retail match and 18 have no published matched price as of 2026-09-13. Prices retain their own observation dates and match status.

EC100 = item price ÷ (elemental mg per serving × servings per container ÷ 100). The table has no price sort across salts. A missing price states the barcode or DSLD identifier searched and the calculation date; no numeric zero substitutes for a missing observation.
