Tesco

Tesco receives a brand trust score of 60/100 in GoodSupp's independent analysis. The company was founded in 1919 and is headquartered in Welwyn Garden City, Hertfordshire, England, UK. 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: Tesco has 2 historical regulatory incidents on record. These are factored into the overall trust score and are detailed in the violation history section above.

GoodSupp's research did not find verified third-party testing certifications for Tesco. 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 Tesco's products are low quality, but it does mean there's less independent verification of their claims.

Based on GoodSupp's quality analysis, the highest-rated Tesco supplements are: High Strength Chewable Vitamin C 1000 mg Orange (score: 81/100); Vitamin B Complex (score: 60/100); Calcium Effervescent Tablet (score: 50/100). 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.
