Frequently Asked Questions
Is Natural Factors a trustworthy supplement brand?

Natural Factors receives a brand trust score of 0/100 in GoodSupp's independent analysis. The company was founded in 1950 and is headquartered in Coquitlam, British Columbia, Canada. They hold 5 verified certifications including B Corp Certified, Usp Verified, Fda Gmp Inspections, Non Gmo Project, Usda Organic. These certifications are independently verified by GoodSupp and indicate the brand meets recognized quality, purity, and manufacturing standards. Note: Natural Factors has 5 historical regulatory incidents on record. These are factored into the overall trust score and are detailed in the violation history section above.

Is Natural Factors third-party tested?

Yes. Natural Factors holds 5 verified third-party certifications: B Corp Certified, Usp Verified, Fda Gmp Inspections, Non Gmo Project, Usda Organic. Third-party testing means an independent laboratory — not the supplement company itself — has verified the product's contents, purity, and/or manufacturing practices. This is one of the strongest indicators of supplement quality because it removes the conflict of interest inherent in self-testing. Not all certifications are equal: NSF International and USP are considered the gold standard, while GMP certification indicates proper manufacturing practices.

What are the best Natural Factors supplements?

Based on GoodSupp's quality analysis, the highest-rated Natural Factors supplements are: SunVitamin D3 1000 IU (score: 100/100); Stress-Relax®, Ashwagandha, 600 mg, 60 Vegetarian Capsules (score: 100/100); Natural Factors BioPQQ Pyrroloquinoline Quinone 20 mg, 30 Veg Caps, Supports Healthy Aging, Proudly Canadian (score: 100/100). These scores are calculated from ingredient quality, dosage adequacy, bioavailability, label transparency, and inactive ingredient safety. Scores can vary significantly across a brand's product line — a high brand trust score doesn't guarantee every individual product is top-quality.

Where is Natural Factors located?

Natural Factors is headquartered in Coquitlam, British Columbia, Canada. The company was founded in 1950. They currently offer 390 products in their supplement lineup. Their official website is naturalfactors.com. Manufacturing location may differ from corporate headquarters — look for GMP certification to verify manufacturing quality standards.
