Igennus Super B-Complex - High A...

Pros

  • Methylated B12 (methylcobalamin) and folate (methylfolate) for superior bioavailability and MTHFR compatibility
  • Clean-label formula with no silicon dioxide, magnesium stearate, or titanium dioxide
  • Sustained-release delivery provides steady energy without afternoon crashes
  • Includes Vitamin C alongside the full B-complex spectrum

Cons

  • Premium price point — not the cheapest B-complex on the market
  • Not independently third-party tested (only lab-verified internally)
  • One reviewer reported a noticeable formula change that reduced confidence in consistency
  • Twice-daily dosing requirement questions the claimed sustained-release mechanism

Best For

People with MTHFR gene variants who cannot efficiently use standard folic acid Those experiencing fatigue, brain fog, or low energy Women seeking hormone balance support (B6/B12 for cycle regulation) Vegans and those with multiple food allergies seeking a hypoallergenic formula Health-conscious buyers who scrutinise additive lists

BioActive Complete B-Complex, 60...

Pros

  • Methylcobalamin (B12), 5-MTHF (methylfolate), and benfotiamine (B1) — premium bioactive forms praised repeatedly by reviewers and confirmed in the formula
  • Multiple reviewers report noticeable energy increases and calmer nervous system within one to two weeks of starting
  • Several reviews from users with doctor-diagnosed B vitamin deficiencies report clear, measurable improvement
  • Transparent ingredient list with no unnecessary fillers — consistently praised across reviews

Cons

  • Distinctive strong supplement smell on opening — multiple reviewers flag it, particularly those sensitive to odours
  • 60 capsules equals only a 30-day supply at the recommended two-per-day dose — shorter than many competitors
  • No independent third-party testing despite premium pricing; LE Certified is Life Extension's own in-house standard
  • Not vegan — vegetarian capsules only, which excludes a portion of the supplement market

Best For

People with MTHFR gene variants who cannot efficiently convert standard folic acid or cyanocobalamin Those with doctor-diagnosed B vitamin deficiencies seeking bioavailable forms High-stress or high-workload individuals needing reliable daily energy and nervous system support Athletes with elevated B vitamin requirements from training load

What does the data say about Igennus Super B-Comple... vs BioActive Complete B-C...?

Both products use methylcobalamin and methylfolate — the bioactive forms that matter for anyone with an MTHFR gene variant — but they differ meaningfully in delivery and formula scope. Life Extension BioActive Complete B-Complex adds benfotiamine, a fat-soluble form of B1 not found in the Igennus product, and comes in a standard capsule. Igennus Super B-Complex uses sustained-release tablets, which reviewers say avoids the energy spike-and-dip you sometimes get from regular B-complexes, and includes vitamin C alongside a clean-label formula free from silicon dioxide, magnesium stearate, and titanium dioxide. On scores, Igennus edges ahead overall (79/100 vs 78/100), with slightly better marks for both effectiveness (82/100 vs 80/100) and ingredient quality (89/100 vs 86/100).

Price is where the choice gets clearer. At £8.08 for 60 capsules — a 30-day supply at the two-per-day dose — the Life Extension option costs far less per month and wins on value for money (72/100 vs 70/100). Igennus at £25.99 for 90 servings is considerably more expensive, though you get three months' worth in one purchase. If you're on a tight budget or just want to test whether a B-complex helps you, Life Extension makes sense. If steady energy release, a cleaner excipient list, and boosted B12 are worth the extra spend, Igennus is the better buy.

One practical note: the Life Extension capsules have a noticeable smell on opening, which multiple reviewers flag. Sensitive noses may find this off-putting. Both come in swallowable formats — capsules versus tablets — so neither is ideal if you struggle with pills.
