Softgels have many desirable properties and several advantages over tablets and hard-shell capsules. Soft gelatin capsules are easy to swallow, disintegrate quickly, and can significantly improve the bioavailability of active ingredients. Softgel capsules can be adapted for many specialized uses. Consumers can see that softgels are hermetically sealed, which not only protects the active ingredients in the fill material from oxidation, moisture, and microbial contamination, but also are tamper-proof. Problems with the one-piece softgels would be indicated through leakage or discoloration. This dosage form is precise and uniform, providing greater stability, purity, and consistency of the nutrients encapsulated.
Another key strength of softgels is their versatility. There are wide varieties of shell colors, shapes, and sizes available to offer product differentiation in the market. Although aesthetically-pleasing supplements appeal to the consumer eye, the inner fill of the capsule is even more important. Softgel capsules can accommodate a wide variety of compounds filled as a semi-solid, liquid, gel, or paste. Also, more emulsion and micro-encapsulated materials are being put into softgel capsules, making them more functional and giving a greater variety of choices as to availability and dosing.
