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

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.
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.
