Solgar Folate Metafolin 1000µg scores 86.0/100 vs Jarrow Formulas Methyl Folate at 81.0/100. Solgar Folate Metafolin 1000µg wins on effectiveness, ingredient quality, side effects. Jarrow Formulas Methyl Folate is stronger on value for money.

Solgar Folate Metafolin 1000µg vs Jarrow Formulas Methyl Folate: What Does the Data Say?

Both products use bioactive methylfolate rather than standard folic acid, meaning neither requires MTHFR enzyme conversion — an important distinction for anyone with C677T or A1298C gene variants. The key difference is dose: Solgar delivers 1,000mcg per tablet, well above the standard 400mcg recommendation, while Jarrow sits at a more conservative 400mcg per capsule. Solgar scores 86/100 at £16.94; Jarrow scores 85/100 at £9.70, with noticeably better value marks (82 versus 73 out of 100).

If you have a confirmed deficiency, elevated homocysteine, or your GP has suggested higher-dose supplementation, Solgar's 1,000mcg makes clinical sense — though medical supervision is sensible at that level. For most people planning pregnancy or supplementing preventatively, Jarrow's 400mcg is the more appropriate starting point, and at nearly half the price it's significantly easier to sustain long-term.

On practicalities, Jarrow has the cleaner profile: small veggie capsules, no gluten, soy, dairy, eggs, or nuts, and consistently praised for easy daily compliance. Solgar's tablets are straightforward but not explicitly allergen-free. Neither product carries third-party certification, so those requiring independent verification will need to look elsewhere regardless of which they choose.
