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 meals — its glucose effects act on the food you're eating. Usually split 2–3 times daily.
With food
On the label
As a dietary supplement, take 2 capsules, 1-3 times daily, just before meals, with 6-8 oz water.
The label says to take it on an empty stomach. What's in this one sits better with food, and you give up little by taking it that way.
General guidance based on the ingredients, not a substitute for the label or your doctor.
