Jarrow Formulas Methyl Folate vs Igennus Super B-Complex: What Does the Data Say?

Vegan Methyl Folate from Jarrow Formulas edges out Igennus Super B-Complex with an overall score of 81.0/100 against 79.0/100. The two differ sharply in formula and format. Jarrow offers a single 400 mcg dose of Quatrefolic 6S-5-MTHF in small veggie capsules while Igennus packs methylated folate and boosted methylcobalamin B12 plus vitamin C into sustained release tablets that spread delivery across the day. Effectiveness sits at 85.0/100 for the Jarrow product and 82.0/100 for Igennus. Ingredient quality scores 90.0/100 versus 89.0/100.

Pick Vegan Methyl Folate if you need targeted support for MTHFR gene variants or confirmed folate deficiency and want the lower price of £9.70 for 60 capsules. Choose Igennus Super B-Complex at £25.99 for 180 tablets when fatigue or brain fog hits and you prefer a full B spectrum with steady energy from the sustained release format. Budget matters here since value scores favour Jarrow at 80.0/100 over Igennus at 70.0/100.

Practical points come down to size and feel. Reviewers praise the tiny capsules from Jarrow for easy swallowing with no taste or smell though some report anxiety if taken alone without B6 and B12. Igennus tablets avoid common additives and give consistent energy without crashes yet cost more for the same daily use.
