Enteric Coating
Also known as: enteric-coated, delayed-release coating, pH-responsive coating, gastro-resistant coating, EC formulation
Effective Dosage
No established dose — enteric coating is a delivery technology, not an active ingredient
What the Science Says
Enteric coating is a pharmaceutical shell applied to tablets or capsules — it is a delivery technology, not an active ingredient itself. The coating resists dissolving in the acidic stomach environment (pH ~1.2) and only breaks down in the more neutral small intestine (pH ~6.8), protecting acid-sensitive compounds from degradation and reducing stomach irritation. Studies show this approach improves the bioavailability of compounds like sulforaphane and proton pump inhibitors, and enables targeted delivery to the intestine or colon for conditions like inflammatory bowel disease.
What It Doesn't Do
Enteric coating is not a supplement ingredient with health benefits of its own — it does nothing by itself. It does not make a weak or ineffective ingredient suddenly work. It does not guarantee better absorption for every compound. Crushing or chewing enteric-coated pills destroys the coating entirely, potentially causing dose dumping or stomach irritation. It is not a sign that a product is higher quality or more potent.

Absorption & Bioavailability
Variable — enteric coating is designed to improve bioavailability of acid-sensitive ingredients by protecting them until intestinal release. Effectiveness depends on the specific polymer used, gastric emptying time, and whether the coating remains intact. Studies confirm negligible drug release at gastric pH and efficient release at intestinal pH when formulations are properly designed.
Red Flags to Watch For
- Never crush, chew, or split enteric-coated tablets or capsules — this destroys the protective coating and can cause dose dumping or stomach damage
- Some enteric coating excipients (e.g., propyl gallate as a permeation enhancer) have shown organ toxicity in animal studies — check full ingredient lists
- Enteric coating listed as a selling point on a supplement label is a marketing feature, not evidence the active ingredient works
- Delayed release means slower onset — do not expect rapid effects from enteric-coated supplements
- Infants and patients with dysphagia cannot safely use standard enteric-coated tablets — alternative formulations are needed
