Is Glycerin Kosher? Here's the One Factor That Matters Most
Glycerin is everywhere — in food, supplements, cosmetics, and beyond. But if you keep kosher, there's one vital question to ask: Where does it come from?
📂 What Is Glycerin Made From?
- Vegetable-based: From soy, coconut, or palm — most commonly kosher-friendly
- Animal-based: From beef or pork fats — not kosher
- Synthetic: From petroleum — may be kosher if supervised and certified
✅ When Is Glycerin Kosher?
Only when all of the following are met:
- Comes from a kosher-approved source
- Produced on kosher-supervised equipment
- Bears a kosher certification (e.g., OU, KOF-K, Star-K)
❌ When Is Glycerin Not Kosher?
- Derived from non-kosher animal fats
- Made on shared equipment with non-kosher products
- Lacks kosher certification — origin and processing unclear
🕵️♂️ How to Spot Kosher Glycerin Products
- Look for kosher symbols: OU, KOF-K, OK, EarthKosher
- "Kosher for Passover" means it avoids grain-based fermentation
- If unsure, contact the brand or certifier
🧠 Bottom Line
Glycerin's kosher status depends entirely on its source and supervision. For full peace of mind, choose products that clearly carry a trusted kosher certification symbol. One ingredient — but two very different outcomes.
