Hard-shell vs. Soft-gel—understanding the animal byproduct

Gelatin is a common ingredient in medications, especially in capsule forms. It is often overlooked because it is not part of the active drug, but for some individuals, it can be an important consideration.

What it is

Gelatin is a protein derived from animal collagen, typically sourced from bovine (cow) or porcine (pig) materials. It is widely used in pharmaceuticals as an inactive ingredient to form capsules and stabilize certain formulations.

Why it matters

For many people, gelatin is not an issue. However, it may matter if you:

  • Have sensitivities or reactions to animal-derived ingredients
  • Follow dietary or religious restrictions (e.g., vegetarian, vegan, halal, kosher)
  • Are concerned about specific sources such as bovine or porcine materials

In these cases, even though gelatin is not the active ingredient, it can still be relevant.

Where it shows up

Gelatin is most commonly found in:

  • Hard-shell capsules – typically two-piece capsules used for powders
  • Soft-gel capsules – sealed capsules often used for oils or liquid formulations
  • Some specialty coatings or formulations

Hard-shell vs. Soft-gel

Understanding the difference can help identify where gelatin is being used:

  • Hard-shell capsules are usually made from two pieces that fit together and often contain powdered medication. These are commonly made with gelatin, though some alternatives exist.
  • Soft-gel capsules are a single, sealed unit that contains liquid or oil-based ingredients. These almost always contain gelatin.

If a medication is labeled as a “softgel,” it is very likely to contain gelatin.

What to watch for

  • Gelatin listed in inactive ingredients
  • Capsule descriptions such as “softgel”
  • References to collagen-derived materials

Not all capsules are gelatin-based, but many are, and the source is not always specified on the label.

What you should do

  • Check inactive ingredients when reviewing medications
  • Be aware that capsule form often indicates gelatin use
  • If needed, ask your pharmacist about alternative formulations

Instead of manually searching labels, you can scan your medication and compare it to your allergen profile.





Use manufacturer to filter generics (fillers/dyes often differ).

NOTE: Generic medications may have different formulas depending on the manufacturer. To confirm the exact ingredients used, consult your pharmacist.

Tip for generics/store brands: Use the exact name as it appears on the bottle, e.g., “Equate” instead of “Walmart”, “GoodSense” instead of “Walgreens”, “Kirkland” instead of “Costco”. If nothing shows up, try leaving Manufacturer blank or searching the generic name only.
