B-Complex Plus

Pros

  • Uses active, methylated B-vitamin forms for superior absorption and bioavailability

  • Clean formulation — minimal excipients, no unnecessary fillers or artificial colours

Cons

  • Premium price point — significantly more expensive than standard B-complex supplements
  • High-dose niacin (as niacinamide) may cause GI discomfort in sensitive individuals
  • Available review data for this exact product is sparse and partially from an unrelated company
  • Bright yellow urine from riboflavin is normal but can alarm first-time users

Best For

People with MTHFR gene variants Those with B12 absorption issues or on plant-based diets Athletes requiring NSF-certified supplements Adults with fatigue, stress, or cognitive fog Anyone prioritising ingredient form quality over cost

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).
