Inside BPN’s Supplement Manufacturer: What This Tour Gets Right (and What Most Founders Miss)
Videos that tour supplement plants are catnip for founders: chrome blenders whirring, tubs zipping down a line, hairnets for days. But the real story lives in the unglamorous details—what gets tested (and what doesn’t), how the rooms are laid out, and where liability quietly rolls downhill onto you.
This post breaks down a manufacturer walkthrough (Formulife producing for Bare Performance Nutrition) from a compliance and quality lens. I’m not affiliated with either company; the goal here is to help you see what a trained eye looks for—so you can vet any plant with confidence.
What you’ll get from this teardown
The big differences between powder runs and other dosage forms (caps, tabs, gummies)
Where “we test everything” often means only ID testing
Green flags that suggest a mature QA culture
Red flags that warrant deeper questions (or a pass)

Short FAQ founders ask when they’re choosing a manufacturer
TL;DR — The three truths hiding in plain sight
Testing ≠ quality. Most plants trumpet “QC testing,” but many mean identification only on raw materials (the minimum FDA requires). Potency, heavy metals, and full micro are often extra—if you don’t ask (and pay) you may not get them.
Design beats cleanup. Room layout, air handling, material flow, and traffic control could prevent problems better than any wipe-down ever will.
The contract decides your fate. Many quotes shift liability to the brand and bury weak testing specs. If it’s not in the MSA/MMR/spec, it doesn’t exist.
Powders are not capsules (and both are not tablets)
The video features powdered products. Powders skip encapsulation and tableting, so:
Fewer unit ops, different failure modes (e.g., flavor/mixability, slack-fill, dust control)
Finished-product micro expectations differ from ready-to-eat foods but still matter
Flavor R&D becomes central—and a surprising time sink if you’re new
If you’re planning capsules/tablets later, know that each dosage form adds:
Additional in-process controls (e.g., capsule weight uniformity, tablet hardness/friability)
More chances for cross-contamination (lubricants, fines, tooling changes)
Different test panels and costs
What the video shows (and how to “read” it like QA)
The visible green flags
Gowning & hair/beard covers. Baseline GMP, good to see it enforced.
Dust collection near fills. Reduces residue and cross-contamination risk.
Segregated rooms. Doors and hard walls between operations beat plastic curtains.
In-process checks. Pulling blend samples for pH/organoleptic and spectral “fingerprints” is a solid control when used consistently.
MMRs and batch records. Required—but the quality of documentation varies by plant. Good that they emphasize it.
The “ask more” moments
Warehouse adjacency. If packaging lines sit in or open to warehouse aisles, you’ve got more external traffic, dust, and pests. Not a deal-breaker—but ask about pest logs, air handling, and traffic controls.
“Everything is QC’d” language. Listen for the specifics: the lab mentioned FTIR/TLC (great for ID) and HPLC (can be great for potency). They also said “sometimes micro” on raws. Translation: full panels are not automatic. Get the default test plan in writing.
Flavor development “free.” Many plants comp flavors at scale clients; startups often pay R&D/time & materials. Clarify fees, iteration limits, and who owns the formula/flavor system.
Brokering vs. making. Not an issue here, but always verify: Who actually manufactures? If your “manufacturer” is a broker, you inherit an extra layer of risk and delay.
The three tests founders confuse (and how to pin them down)
Identification (ID)
Confirms the material is what it claims (e.g., creatine is creatine). Often done by FTIR/TLC.Regulatory minimum for every incoming lot.
Does not confirm potency, purity, or contaminants.
Potency/Assay
Quantifies active(s) (e.g., 200 mg caffeine/serving). Typically HPLC/GC/ICP depending on analyte.Not automatically run on each lot at many plants.
You must specify per raw and/or finished product.
Contaminants
Micro: APC/yeast & mold/coliforms/pathogens (e.g., Salmonella).
Chemical: Heavy metals (As/Cd/Pb/Hg), residual solvents, phthalates, etc.
Allergens/adulterants as applicable.
These are often risk-based; many plants default to micro on finished goods for powders and skip metals or only test periodically.
Action: In your quote/PO/specs, require a matrixed test plan by material and by finished lot. If the price drops when tests drop, you have your answer.
Design > disinfectant: why room layout matters
You’ll never swab your way out of a bad floorplan. When touring, look for:
Product & personnel flow: Dirty → clean; warehouse traffic kept out of processing rooms.
Air handling: Positive pressure in clean areas, HEPA where appropriate, no condensate on vents.
Ceiling & floors: Nothing shedding above open product; hoses off the floor.
Segregation by allergen & form: Proteins far from botanicals, powders away from liquids where possible.
If you see pristine machines but a chaotic hallway stuffed with pallets, that chaos eventually lands in your tub.
Contracts & quotes: where liability shifts to you
Many “standard” quotes sneak in clauses like:
Customer responsible for finished-product testing
Manufacturer indemnified for most regulatory issues
Specs limited to ID and basic micro (no potency/metals)
Fix it before you wire a deposit:
Attach a finished-product specification that lists all tests, methods, limits, and label-claim tolerances.
Add release criteria (no ship without passing CoA that matches spec).
Define stability/shelf-life support if you print a date code.
Lock change control (no substitutions without written approval).
Slack-fill is real (and litigated)
Powders settle. You still need to minimize “empty space” or plaintiffs’ firms will notice. Pick the smallest compliant tub, validate fill accuracy, and monitor over the life of the run. Document why your headspace is necessary (scoop insertion, dust control, sealing).

Founder FAQs
Q1) My manufacturer says they “test everything.” Is that enough?
Usually that means ID only on raws and basic micro on finished goods for powders. Specify potency and heavy metals at minimum; add risk-based tests per formula.
Q2) Do I need heavy-metal testing on every lot?
For botanicals/minerals and proteins: generally yes, every finished lot (or, at minimum, high-risk raws every lot). For low-risk synthetics: a validated periodic plan may work—document your rationale.
Q3) Who pays for testing?
If it’s not in your spec and PO, you do (or it won’t happen). Bake test costs into your COGS. Cheap quotes often hide minimal testing.
Q4) Can I rely on flavor houses to make my powder “taste great”?
Yes—if you set constraints: sweetener type, acid system, label claims (e.g., “natural flavors”), and ownership of the flavor system. Otherwise you’ll be locked in.
Q5) Is packaging in the warehouse a deal-breaker?
Not automatically, but it raises questions. Ask about air handling, pest control, and how they protect open product. Higher-end plants keep packaging in controlled rooms.
Q6) How do I avoid slack-fill lawsuits?
Pick the tightest tub that fits your scoop/fill. Validate fill weights, document headspace rationale, and keep proofs. Don’t over-package for “premium feel.”
The bottom line
Plant tours are fun, but your success is decided by design, documentation, and definitions—of tests, specs, and accountability. Treat the quote and the spec as product-development documents, not paperwork. If the manufacturer welcomes your specificity and QA questions, you’ve likely found a possible partner. If they bristle, believe them the first time.
