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
Best taken in the morning
The Vitamin B12 in it is what pulls this toward the morning. Take it with a meal containing fat — the vitamin E in it absorbs poorly without one.
With a meal containing fat
NAC 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.
On the label
One to two (1-2) capsules daily, or as directed by a healthcare professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
