Frequently Asked Questions
What testing evidence is available for Swanson?

The September 3, 2026 review found public listings from SuppCo, ConsumerLab, Labdoor. The evidence table identifies the products or company listings covered. A publisher listing does not mean every product has passed testing.

What are the best Swanson supplements?

Based on GoodSupp's quality analysis, the highest-rated Swanson supplements are: Maximum-Strength Fermented Turmeric (score: 100/100); WellCore Defense with EpiCor & Wellmune (score: 100/100); American Ginseng 300 mg (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 Swanson located?

Swanson is headquartered in Fargo, North Dakota, United States. The company was founded in 1969. They currently offer 1329 products in their supplement lineup. Their official website is swansonvitamins.com. Manufacturing location may differ from corporate headquarters — look for GMP certification to verify manufacturing quality standards.
