- Regulatory synthesis of multiple RCTs: RBC folate 23% higher (95% CI 11-37%) for L-5-MTHF vs folic acid at >=400 mcg/day, chronic dosing. THE BASIS OF THIS DCR. EFSA also treats the calcium and glucosamine salts as bioequivalent per mg of active 5-MTHF, citing an UNPUBLISHED 2010 crossover (n=24) - that salt-parity claim is UNVERIFIED. DOI
- Narrative review. States folic acid and L-5-MTHF are comparable at EQUIMOLAR doses (reads ~1:1). Directional support only - a review, not a ratio source. Mass-corrected this would give ~1.04, which is direction-illegal for S4->S1. PubMed DOI
