Capsule ShellCapsule

Generic capsule shell where the label does not specify the material. Common materials are hypromellose (HPMC) for vegetarian capsules and gelatin for traditional capsules — both are GRAS-listed and safe. Fish gelatin and pullulan variants also exist.

How to Take It

Take it anytime

Take with food to avoid stomach upset. Benefits, where they exist, take weeks of daily use to appear.

With food

Glutamine does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.

Split into 2 doses across the day

On the label

As a dietary supplement, take 2 capsules, twice daily, with or between meals.

General guidance based on the ingredients, not a substitute for the label or your doctor.
