Capsule FAQ

Pharmaceutical Capsules

Are your capsules pharmacopoeia approved?

Yes, they are. Under the 1996 revision to the Japanese Pharmacopoeia, capsules are defined as being "made using appropriate base capsule materials listed in the Japanese Pharmacopoeia."

Gelatin Capsules

How safe is pork-derived gelatin?

The pork-derived gelatin used in the manufacturing process of our gelatin capsules is sterilized by the raw material manufacturer during the manufacturing process by heating to 138°C. An administrative notice (dated April 26, 2009) issued by the Tuberculosis and Infectious Diseases Control Division of the Ministry of Health, Labor and Welfare's Health Service Bureau stated that when preparing porcine meat for consumption, cooking the meat so that the internal temperature reaches 71°C is sufficient to kill the swine influenza virus. Therefore, we believe that the pork-derived gelatin used here at Qualicaps poses no safety issues.
