Vege Caps or Gelatin Caps?

Vege caps does not seem advantageous compared to Gelatin form capsules. While vege-caps dissolve in water, they do not dissolve in acid, and instantly coagulate, capturing food in them. Our stomach is filled with acid. Gelatin capsules dissolve in the stomach. This permits the product they contain to stay longer in the active gastro-intestinal tract, to be better processed and to deliver their full spectrum of mineral properties. Also Vegetarian capsules lack naturally occurring protein. As a result, the stomach does not recognize a vegetarian capsule as food, so the capsule only dissolves in bile, in the lower GI tract.
