Basic Nutrients 2/Day
Thorne's formula is the gold standard for bioavailability, utilizing methylated B vitamins and chelated minerals that the body can actually absorb. It carries the NSF Certified for Sport designation, ensuring it is free from 200+ banned substances and that label claims are 100% accurate.
Ingredients & Purity
Features 2,000 IU of Vitamin D3, K2 (MK-4) for bone health, and the active form of folate (5-MTHF) rather than synthetic folic acid.
Scientific Evidence
NSF Certified for Sport; Thorne is the only supplement brand to collaborate with the Mayo Clinic on health and wellness research.
Brand Transparency
Full disclosure of ingredient forms and sources; manufactured in an NSF-certified, cGMP-compliant facility.
Value Assessment
At roughly $1.00 per day, it is more expensive than mass-market brands but offers significantly higher nutrient density and absorption rates.
Why Not Alternatives?
Unlike One-A-Day or Centrum, Thorne avoids low-quality oxides and carbonates, opting instead for superior bisglycinates and malates. It also excludes unnecessary synthetic dyes (like Red 40 or Titanium Dioxide) found in most drugstore brands.
