magnesium stearate

Magnesium outside the quantified panel

Magnesium stearate has a reference elemental magnesium fraction of 4.1% by mass in the chemistry model used 2026-09-13; the 284 labels here list it among other ingredients.

This label lists magnesium stearate, whose reference elemental fraction is 4.1% by mass. No stearate quantity is available in this record as of 2026-09-13, so its magnesium contribution cannot be quantified or added to the Supplement Facts magnesium total.

The quoted statement appears on the linked product records. The 4.1% fraction describes the stearate compound, not a 4.1% addition to any label's declared magnesium amount.

How this group is counted

284 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.

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

• Magnesium Stearate
• Magnesium Stearates
• Magnesium Vegetable Stearate
• Veg. Magnesium Stearate
• Vegetable Magnesium Stearate

Salts and physical states

284 matching labels occupy 12 resolved-salt or unresolved groups and 5 physical-state groups, using NIH DSLD records classified 2026-09-13; each distribution totals 284.

Filed labels and observed prices

284 labels are listed below in brand and product order; 30 have a published retail match and 254 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.
