Quality & testing.

The National Animal Supplement Council audits its members for ingredient quality, dosing accuracy, label truthfulness and adverse-event reporting. Membership isn't bought — it's inspected.

• Facility and process audits by NASC
• Adverse-event monitoring and reporting
• Label claims that match what's in the jar

The lot number printed on the bottom of every jar maps to a Certificate of Analysis. If your vet wants proof before recommending APEX, that's the document to send them — request your lot's COA here.

• One COA per production lot
• Covers identity, potency, heavy metals and microbials
• Available on request, free, no hoops

Every batch is screened for the four heavy metals that matter in pet supplements — because "natural ingredients" can still carry what the soil carried.

• Lead
• Arsenic
• Mercury
• Cadmium

Powder that sits in a jar for 30 days has to start clean. Each batch is tested for the pathogens that cause recalls in the pet-food industry.

• Salmonella
• E. coli
• Total yeast and mold counts

Two questions every supplement should answer and most don't: is the ingredient what the label says, and is there as much of it as the label says? We test both, per batch.

• Ingredient identity verified against reference standards
• Active doses confirmed at clinical levels on the label
• The scoop in your jar delivers the dose we tested

Quality is also what you refuse to put in. The exclusion list is as deliberate as the formula.

• No wheat, corn or soy — the top three canine allergens
• No maltodextrin, sucrose or artificial sweeteners
• No artificial colors or dyes
• No BHA, BHT or ethoxyquin — vitamin E preserves it naturally
• No bulking fillers
