Frequently Asked Questions
Is Natural Factors a trustworthy supplement brand?

Natural Factors receives a brand trust score of 100/100 in GoodSupp's independent analysis. The company was founded in 1950 and is headquartered in Coquitlam, British Columbia, Canada. Our research did not find independently verified third-party certifications for this brand. While this doesn't mean their products are low quality, third-party testing is considered a strong indicator of commitment to quality assurance. 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?

GoodSupp's research did not find verified third-party testing certifications for Natural Factors. Third-party testing by organizations like NSF International, USP, or Informed Sport is considered one of the strongest indicators of supplement quality. Without it, consumers must rely more heavily on the brand's own quality claims. This doesn't necessarily mean Natural Factors's products are low quality, but it does mean there's less independent verification of their claims.

What are the best Natural Factors supplements?

Based on GoodSupp's quality analysis, the highest-rated Natural Factors supplements are: Vitamin D3 LipoMicel Matrix (score: 100/100); Vitamin K2 100 mcg (score: 100/100); SunVitamin D3 1000 IU (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 832 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.
