Vegan & Vegetarian Check: What's the Capsule Shell?

2026 guide · CardioC2 Team

A capsule's shell material isn't always obvious from the named active ingredients alone — worth checking directly if a vegan or vegetarian diet matters to your decision.

What to actually check

Confirm directly with the seller whether the capsule shell is gelatin-based (not vegetarian) or a plant-based alternative like HPMC, since this isn't specified on the pages reviewed.

Why this is worth checking separately from the eight named actives

Beta-Cyclodextrin, Beet Root Extract, L-Citrulline, Hawthorn Berry, L-Arginine, L-Theanine, Black Garlic Extract and CoQ10 are all plant-based compounds, but the shell material itself is a separate formulation choice worth confirming.
