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
Best taken in the morning
The Vitamin B2 in it is what pulls this toward the morning. Take it with a meal containing fat — the vitamins A and E in it absorb 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.
Space it a couple of hours from Iron and Calcium
On the label
As a dietary supplement, take 1 capsule, 1-2 times daily, with meals.
