Quality checks at every stage.
At Physician's Choice, quality is not something we check just once. Every product routinely goes through six stages of quality control, from the moment raw materials arrive through production, finished product testing, and ongoing stability monitoring. We work closely with our manufacturing partners to help ensure every batch meets the standards our customers expect and deserve.
01Raw material qualification
Before any ingredient enters production, we work with our manufacturing partners to qualify every supplier. This includes verifying certificates of analysis, confirming ingredient identity, and ensuring each raw material meets our specifications for purity and potency. No ingredient moves forward in the process until it has been properly vetted.
02Incoming raw material testing
Prior to weigh-up and blending, raw materials undergo identity testing to confirm that what we received matches what was ordered. This step protects against ingredient substitution, mislabeling, or contamination before it ever has the chance to impact a finished product.
03In-process checks
Quality is monitored throughout manufacturing through routine in-process checks to verify that critical process parameters remain within established specifications. Depending on the product, these may include weight or fill verification, pH, moisture or water activity, viscosity, seal integrity, and visual inspections to help ensure consistent product quality before final release.
04Finished product testing
Once a batch is produced, finished product testing is performed to verify that it meets established quality specifications. Depending on the product, testing may include identity, potency, purity, microbiological quality, and other quality attributes to help ensure the product meets label claims and our quality standards.
05Retain inspections
Retained samples from every batch are inspected to verify that the finished product continues to meet quality standards, including appearance, color, odor, texture, and overall organoleptic characteristics. These inspections help ensure product consistency over time.
06Stability testing
We conduct stability testing to evaluate how our products perform over time under recommended storage conditions. These ongoing studies help establish and verify shelf life while confirming that products continue to meet quality, potency, and safety standards throughout their intended shelf life.
Third-party testing
We work with independent laboratories, including Eurofins and Light Labs, to test for purity, potency, and safety, confirming that what's listed on the label remains in the bottle throughout shelf life, while screening for heavy metals and harmful microorganisms.
Rigorously tested.
Across our quality program, we test the ingredients inside our products, the amounts provided, and the presence of unwanted contaminants. Here's a closer look at what we test for and why.
Identity testing
Confirms that ingredients and finished products are what they claim to be.
Why we test for it: to help ensure the correct ingredients are used, and protect against substitutions, mix-ups, and mislabeled materials.
Potency testing
Verifies that active ingredients meet established specifications and label claims.
Why we test for it: to confirm each serving provides the intended amount of active ingredients listed on the label.
Probiotic enumeration
Measures probiotic levels in applicable formulas.
Why we test for it: to verify probiotic products meet their CFU count specifications and provide the levels stated on our labels.
Microbial testing
Screens finished products for harmful microorganisms.
Why we test for it: to ensure products are free from harmful levels of unwanted bacteria, yeast, and mold.
Heavy metal testing
Screens for the heavy metals most scrutinized in supplements.
Why we test for it: to ensure heavy metal levels remain within established safety specifications before a product reaches you.
Certified to the standards that matter.
Our manufacturing partners maintain a range of industry certifications and quality standards, which may include:
NSF cGMP certified
Indicates a facility has been independently audited to verify compliance with current Good Manufacturing Practices: a commitment to consistent quality, proper controls, and product integrity.
Non-GMO Project Verified
Select products are independently evaluated against the Non-GMO Project Standard, adding transparency into ingredient sourcing and supply-chain controls.
GFSI certified (FSSC 22000)
Manufactured in facilities independently audited to internationally recognized food-safety standards: rigorous food safety and quality management throughout the process.
No single facility does everything well.
That's why we work with a network of specialized manufacturing partners, each bringing unique strengths in format, technology, and scale, so that every product we bring to market is made the right way, by the right team, with the right equipment. Every facility in our network operates under the same expectations:
Probiotic manufacturing
We partner with manufacturing facilities that specialize in handling live cultures and moisture-sensitive ingredients. These facilities utilize controlled manufacturing and packaging processes designed to help protect product quality and probiotic viability throughout production, supporting products that meet our quality standards and label claims.
Powder & stick pack manufacturing
Our powders and single-serve stick packs are produced by a partner specializing in precision blending and sachet filling. Exact-dose formulas are blended for consistency and filled into single-serve packs, with quality checks at each stage to ensure every serving delivers the same texture, flavor, and active content.
Gummy manufacturing
Our gummies are made through a highly controlled process: ingredients are mixed to exact formulas, poured into precision-molded shapes, and cooled under carefully managed conditions to develop the ideal texture. Quality checks happen at every stage, ensuring consistency at a scale most manufacturers simply can't match.
Capsule manufacturing
Our capsule products are made by a global leader in the nutrition and wellness space with deep expertise in producing high-quality supplements. This facility uses advanced technology and rigorous quality checks at every stage to make sure each batch is consistent, dissolves properly, and stays effective all the way to your door.
