Dietary Supplement Solutions
Laboratory Testing, Quality & Scientific Support for Dietary Supplement Manufacturers
Dietary supplement manufacturers must understand and control scientific variables across
ingredients, raw materials, formulations, contaminants, microorganisms, manufacturing
processes, finished products, stability, and quality programs.
Products may contain multiple ingredients from different suppliers, complex formulations, and
raw materials with naturally variable characteristics.
.
As a result, manufacturers may encounter questions such as:
Are incoming ingredients consistent?
Could heavy metals or other contaminants be present?
Why does one production lot differ from another?
Is microbial contamination affecting the product or process?
How should we investigate an unexpected laboratory result?
What analytical approach is appropriate for this product?
CMDC Labs supports appropriate dietary supplement projects with multidisciplinary resources
spanninganalytical testing, raw-material testing, heavy-metal analysis, microbiology,
product characterization, stability-related investigation, product development, scientific
troubleshooting, method development, scientific consulting, and quality and regulatory
support.
