The main differences are material, dissolution speed, and target market. Gelatin capsules are made from bovine gelatin, dissolve in approximately 15 minutes, and are the most cost-effective option for broad-market supplements. Vegetarian capsules (HPMC or pullulan) are plant-based, dissolve in approximately 30 minutes, and are preferred for vegan, vegetarian, or clean-label products. Both types are available at Capsuline with the same pharmaceutical-grade quality standards.
