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 plenty of water. Fiber binds other things in the gut, so give it a 1–2 hour gap either side.

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.

Keep it away from medication and mineral supplements

On the label

As a dietary supplement, take 3 capsules daily, between meals with 8-12 oz water, or as directed by a health professional. Daily water intake should be increased when consuming this product.

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