Dr. Newton’s Naturals is proud to partner with Nulab for the manufacture of many of our high quality vitamin and mineral supplements. Nulab is an FDA-registered manufacturer of dietary supplements. They have been manufacturing tablets, capsules and powders for over 20 years. The focus of their production process is to maintain a standard of quality throughout manufacturing that results in an exceptionally high quality product.

Manufacturing takes place in their Clearwater, Florida factory. With over 65,000 square feet, 20,000 of which is clean-room production space, and with modern automatic equipment to make tablets, capsules, powders, liquids and blister packs, Nulab has an incredible production capacity.

Quality Control

Nulab’s manufacturing is based on a system that is centered on quality control. Control of quality exists at each step throughout their production process. It does not consist simply of checking the finished product—it is an integral part of all that they do.
Nulab builds quality into the product at each production step. From screening of raw materials, through the steps of weighing, mixing, encapsulation or tableting, and bottling, a Quality Control inspector is on hand on the production floor to make sure that at each point a Standard Operating Procedure is followed.

FDA Compliance

The new regulations from the FDA for the dietary supplements industry (“Current Good Manufacturing Practice in Manufacturing, Packaging, Labeling or Holding Operations for Dietary Supplements”, 21 CFR , Part 111) has brought fundamental changes to the way dietary supplements are manufactured in the USA.

What used to be a food-based production process that focused on hygiene and cleanliness has now been tightly regulated, requiring that the manufacturer ensures the “identity, purity, strength and composition” of the ingredients it uses as well as its finished products.

Nulab has implemented in-process controls to comply with these new rules:

Ingredient Screening – Nulab screens each dietary ingredient in two steps. First, they validate by analysis its identity and potency. They then make sure that it does not contain contaminants, such as harmful microbes, yeast, mold, heavy metals, pesticides and foreign particles.

In-Process Controls – Each step of the production process, from the receipt of raw materials to the release of a finished product, has its own precise SOP (Standard Operating Procedure). Following these SOPs ensures that the product is made per its Master Manufacturing Record.

Product Certification – Before Nulab releases a product they analyze it to verify its potency and other specifications per its Master Manufacturing Record.
