DHC SUPPLEMENT
PRODUCTION PROCESSES

DHC’s painstaking supplement production process consists of multiple stages, from preparation of raw materials to delivery of final products to customers.

stepO1

Weighing and
mixing capsule
contents

After measuring the total weight of the raw materials, contents are moved from drums to vacuum emulsifiers. Once all raw materials have been added, the resulting mixture is agitated to a uniform consistency. The contents are then passed through a fine filter to a separate tank while checking for impurities or other defects.

stepO2

From capsule
formation to
tumbler drying

Capsule formation

Supplement capsules are made of gelatin. Two sheets of gelatin are punched into semispherical halves. The specified contents are injected before the two halves are brought together. The machinery operates around the clock, producing 75,000 capsules per hour.

Tumbler drying

Capsules are dried for 24 to 30 hours while exposed to streams of air inside a drying room with a room temperature of about 23°C and humidity of 30% or less.

stepO3

Laser printing

The DHC logo is laser printed on each capsule in a pocket.

stepO4

Visual capsule
sorting

Capsules are checked visually for scratches, deformation, air bubbles, laser misprinting, and other defects. These duties are handled by staff who are required to pass tests administered every three months. Each staff member is able to check some 50,000 capsules in approximately 15 minutes.
