Additive identity
Possible source pathways
The finished molecule can be identical across feedstocks. The Halal ruling follows the pathway, not the code alone.
- plant · Typical Halal Fatty acids from palm, soy, sunflower, or other vegetable oils.
- animal Halal if verified The same esters can be split from tallow or lard. Pork or non-zabiha fat is haram.
- undisclosed · Typical Halal if verified Most labels print only the E-number or US name. Treat as mashbooh until a plant, vegan, or Halal claim settles the fat.

Why this ruling
Magnesium stearate is the flow agent in a huge share of tablets. Codex numbers it INS 572; older EU paperwork used E572. E573 is aluminium stearate. Neither metal is the Halal issue. Stearic acid may be palm or tallow.[4][2]
It is not on the current EU Union list.[1] US labels still print the name constantly. Unspecified magnesium stearate is mashbooh.[5] 'Vegetable stearate' or a Halal mark closes it. Still check whether the capsule is gelatin.
Where you'll find it
- Tablet and capsule flow agent
- Confectionery anti-caking (legacy / non-EU)
How to verify
1) Match magnesium stearate, vegetable stearate, E572, INS 572, or aluminium/aluminum stearate (E573). 2) 'Vegetable stearate' or Halal-certified capsules settle it. 3) Related food salts are E470a/b; free acids are E570.
- E572 = magnesium stearate.
- Stearic acid source decides.
- Not a current EU food-additive code; still used on US labels.
Conditions for Halal
- Vegetable stearate or Halal-certified tablet → Halal
- Pork or non-zabiha tallow stearate → haram
- Unspecified magnesium stearate / E572 → Halal if verified
- Capsule shells (gelatin vs HPMC) are a separate check
Scholarly differences
Magnesium stearate is one of the most searched Halal supplement ingredients. The metal is not the issue; stearic acid is. Do not invent a fatwa that all magnesium stearate is haram, or that all of it is palm.
