Two-piece capsules have been made from gelatin since they were originally patented by James Murdock in 1847. Gelatin (also spelt Gelatine) is an animal protein which what know as Generally Recognised as Safe (GRAS) in pharmaceutical and food consumption by the majority of international regulatory bodies. Our empty gelatin capsules are GMO free and derive from completely natural sources. Gelatin capsules are usually derived from beef or pork along with water and a plasticizing agent such as glycerine to provide durability. Gelatin is an essential component for human consumption and development.
HPMC capsules are manufactured from Hydroxypropyl Methylcellulose and is globally referred to also as “Hypromellose”.
HPMC is derived from plant cellulose and was one of the first alternatives available for vegetarians. Hydroxypropyl Methylcellulose rose to popularity in the early 2000s as it proved to be a stable polymer with a low moisture content that makes it suitable for moisture-sensitive ingredients. It is also extremely resistant to higher than average heat and humidity.
Our vegetable capsules or "veggie caps" as they are often referred to are manufacture out of tapioca extract. The benefits of empty veggie capsules over HPMC capsules is mainly how comfortable your customers or whoever is consuming the capsules are with which ever source they are consuming.
Our vegetable capsules offer a balance of performance within high output capsule manufacturing and clean label ingredients for health conscious manufacturers and consumers. Made from tapioca which is naturally fermented into pullulan, a starch-free vegetarian capsule, our Veggie capsules speak to the needs of the most discerning consumers.
