Kosher capsules and gelatin: softgels, veggie caps and fish gelatin

By the KosherVitamins.com team · Updated November 6, 2026

Capsules are where many supplements run into kosher problems, because standard gelatin is often made from non-kosher animals. Here is what each type of capsule is made of and what the major agencies say.

Types of capsules

What makes gelatin kosher

The OU accepts gelatin made from kosher species of fish (from fish skins, under strict supervision) or from the hides of kosher-slaughtered cattle, and certifies plant-based gelling agents such as pectin. COR in Toronto accepts pareve gelatin made from dried hides of kosher animals, following Rav Moshe Feinstein, and notes that some authorities treat any kosher animal gelatin as meat. Kosher fish gelatin often carries a fish designation (for example OK-Fish).

The Star-K warns that a label reading "kosher gelatin" or "K-gelatin" without a reliable agency symbol can be misleading. Gelatin from shellfish or non-kosher fish is not kosher.

Gelatin from non-kosher animals

Major Orthodox agencies do not certify gelatin from non-kosher animals. COR writes that "the greatest poskim of the generation did not accept animal gelatin as kosher." A minority view holds that gelatin becomes a new substance during processing. If you follow a specific standard, ask your rabbi.

Hard capsules vs. softgels for someone who is ill

When no kosher alternative exists, authorities differ on gelatin capsules taken as medicine:

• Rav Yisroel Belsky (OU): hard gelatin capsules may be used by someone who is ill when there is no kosher alternative (for example, don't take a capsule when the same product comes as a tablet). Softgels should not be used; if there is truly no alternative, he recommended wrapping the softgel in tissue paper before swallowing, so it is swallowed in an even more unusual manner.
• Rav Hershel Schachter (OU): sees no difference between hard and soft gelatin; either may be swallowed for medical reasons.
• cRc: both hard capsules and softgels need kosher certification. A seriously ill person with no gelatin-free option may take them, but a person taking softgel vitamins for general wellness may not.
• COR: healthy people taking daily vitamins need reliable certification, and even people who are ill should avoid softgels.

Some people instead place a softgel inside an empty vegetable capsule. This is not part of Rav Belsky’s guidance, so ask your rabbi whether it works for you. We carry kosher empty vegetable capsules.

For everyday vitamins, the simplest choice is a certified product in a vegetarian capsule, a kosher-gelatin softgel, or a tablet.

Other capsule and coating ingredients

• Glycerin makes softgels soft and is a key ingredient in liquids and gummies; it can be animal-derived and needs certification.
• Carmine (red color from insects) is not kosher, per the cRc and COR.
• Shellac coatings are accepted by U.S. national agencies.
• Stearates are often animal-derived. The Star-K and COR treat small amounts in medicines as nullified; in supplements the Star-K requires certification.

Label tips

• "Vegetarian capsule," "veggie cap" or "plant-based capsule" means no gelatin capsule, but look for the kosher symbol too.
• A softgel or gelcap is gelatin unless the label says otherwise.
• If a product comes as both a tablet and a gelcap, the tablet usually avoids the gelatin question.
• Gummies: check whether they use kosher gelatin or pectin, and look for the symbol.
