For the past 15 years Provillus has been one of
the leading manufacturers and distributors of herbal supplements,
liquid formulas, and capsule products focused on restoring hair
growth.Our products are made from finest pharmaceutical grade ingredients
available and all of our raw materials must pass stringent quality
controls before they are utilized.
Provillus products are manufactured using the US Federal Drug Administration
Good Manufacturing Practices.
Provillus Quality Control
Prior to production all raw materials are tested for purity. Throughout
the production process quality control engineers have the authority
to reject any product that does not adhere to our strict quality
standards. During the manufacturing process every step is documented
and reviewed by quality control specialists.
To ensure the absence of any contamination during the manufacturing
process, manufacturing equipment is maintained and cleaned on a
predetermined schedule. All inspections are documented in company
logs for review by the Department of Agriculture.
Additionally the following steps are taken to ensure quality control:
This analysis contains the specific components of the herbal product
including a lot number for each of the ingredients and the production
All of the raw materials in our products come with a Certificate
of Analysis provided by the supplier. Additionally our in house
quality assurance team analyzes the raw materials for authenticity
upon delivery to ensure the shipments match the Certificate of Analysis
provided by the supplier.
All new labels are cross checked with the original master label
to ensure there has been no mistakes during the printing process.
Once an order request has been received a complete list of raw materials
is entered in the production records and a lot number is assigned.
The raw materials are subsequently released to the pharmacy once
all products have been checked for authenticity.
To ensure the highest quality control Provillus also adheres to
the following manufacturing guidelines:
Blending and Granulation
Prior to production all equipment used for in the process of mixing
and granulation is inspected by the director of operations. Raw
materials are then inspected for the final time and the lots are
then processed according to the strict guidelines for each herbal
product. Following granulation and blending the powder blends are
stored in specifically designed containers to ensure freshness and
to avoid any contamination.
Encapsulation and Compression
Once a test unit has been processed a sample unit is sent to quality
assurance to be compared to the control samples to insure product
integrity. Once the new unit has been approved by quality assurance
the full line production may begin. Quality assurance inspections
are conducted using set protocols for the capsules. As with the
blending and granulation process the capsules are stored in specifically
designed containers to ensure freshness and to avoid any contamination.
The production of liquid products follows the same stringent protocols
as the production of capsules previously detailed.
Packaging and Inspection
The quality control staff inspects the final product and broken
tablets, over filled capsules, and other defective finished products
are removed from the lot. Products released by the quality control
staff are subsequently either packaged for bulk storage or bottled
and labeled for consumer use. Product labels contain the appropriate
information as required by the Federal Drug Administration and batch
numbers are logged.
The quality control unit also retains samples of raw materials
for one year past the expiration date of the last product they are
used in and finished products for one year past the product expiration
date are maintained under control conditions.
Finished products are stored in a climate controlled environment.
