What does the data say about Igennus Super B-Comple... vs B-Complex Plus?
Both products use methylated B-vitamin forms—methylcobalamin for B12 and methylfolate—which means they're absorbed properly even with MTHFR gene variants. Igennus scores higher on effectiveness (82/100 vs 74/100) and uses a clean label without silicon dioxide, magnesium stearate, or titanium dioxide. Its sustained-release tablets deliver steady energy. Thorne's ingredient quality is slightly better (91/100 vs 89/100). Price-wise, Igennus is £25.99; Thorne's isn't listed publicly.
Igennus wins on value (70/100 vs 62/100). Pick it if you want sustained-release delivery and fewer fillers. Choose Thorne if you prioritise absolute ingredient purity. Thorne uses niacinamide (high-dose niacin), which can trigger flushing or stomach discomfort in sensitive people—Igennus avoids this. Both work well for MTHFR variants and fatigue. Your choice comes down to sustained-release convenience and cleaner additives (Igennus) versus maximum ingredient quality (Thorne).
Igennus Super B-Complex is a premium UK-formulated B-vitamin supplement using methylated and active forms of all 8 B vitamins, including methylfolate and methylcobalamin B12, making it particularly suitable for those with MTHFR gene variants who struggle to convert standard folic acid.
