Today, we're stepping into another part of our GMP‐certified facility to show you how supplement oral liquids are made - a process that demands precision, hygiene, and advanced technology to ensure every bottle delivers safety, potency, and consistency.

1. Formulation & Raw Material Sourcing

Every oral liquid starts with a scientifically designed formula:

• Active ingredients: vitamins, minerals, herbal extracts, amino acids

• Supporting components: stabilizers, sweeteners, natural flavors

• Designed for taste, solubility, and shelf life

We source all raw materials from audited, trusted suppliers to meet international quality standards.

2. Ingredient Testing & Preparation

On arrival, ingredients are:

• Quarantined and tested for purity, potency, and contaminants (heavy metals, microbes, pesticides)

• Liquids and extracts are filtered to remove impurities

• Powders are pre‐dissolved or emulsified for uniform mixing

3. Mixing & Homogenization

In stainless steel mixing tanks, ingredients are combined under controlled temperature and agitation. For certain formulas, high‐shear mixers or homogenizers are used to:

• Achieve even distribution of active ingredients

• Create stable emulsions for oil‐in‐water blends

• Ensure consistent taste and texture

4. Pasteurization or Sterilization (If Required)

Some formulas undergo heat treatment or sterile filtration to:

• Extend shelf life

• Ensure microbial safety without degrading active compounds

5. Filling & Nitrogen Protection

The prepared liquid moves to the filling line, where:

• Bottles or vials are automatically cleaned and sterilized

• Liquid is filled to precise volumes

• Nitrogen flushing may be used to displace oxygen, protecting sensitive ingredients from oxidation

6. Sealing & Capping

Containers are sealed immediately to prevent contamination. Depending on the product, this may include:

• Screw caps

• Dropper caps

• Heat‐sealed foil lids

7. Labeling & Batch Coding

Each unit is labeled with:

• Product name and ingredients

• Usage instructions

• Batch number and expiration date (printed via continuous inkjet coding)

8. Quality Control & Inspection

Our QA team conducts:

• In‐process checks for fill volume, seal integrity, and label accuracy

• Final product testing for potency, purity, and stability

• Visual inspection to remove any defective units

9. Packaging & Shipping

Finished bottles are:

• Packed into inner boxes, then outer cartons

• Palletized for safe transport

• Stored in climate‐controlled warehouses until shipment
