Fully Active B Complex, 60 Veg Caps
Pros
- ✓Active B vitamin forms throughout — Quatrefolic® folate, methylcobalamin B12, riboflavin 5'-phosphate — not cheaper synthetic alternatives
- ✓Reviewers consistently report reduced fatigue and better energy, often noticing effects within a few days
- ✓1000mcg methylcobalamin per capsule is a solid B12 dose at a price most reviewers call good value for a 2-month supply
- ✓Niacin delivered as niacinamide — no flush reported, and capsule size described as easy to swallow with no aftertaste
Cons
- ✗Bright yellow urine and occasional smell from sweat noted by several users — harmless but worth knowing before starting
- ✗Some users report burping or mild digestive discomfort after taking, particularly on an empty stomach
- ✗No third-party testing — the active form claims rely on brand transparency, not independent verification
- ✗One reviewer questions whether all forms are truly active, suggesting some inactive B vitamin forms may be included alongside the premium ones

What does the data say about Fully Active B Complex... vs Igennus Super B-Comple...?
Both products score 79/100 overall and 82/100 for effectiveness, so the real differences come down to ingredient delivery and price. Doctor's Best Fully Active B Complex uses Quatrefolic folate, methylcobalamin at 1,000mcg per capsule, and riboflavin 5'-phosphate — all active forms your body can use directly. Igennus Super B-Complex also uses methylcobalamin and methylfolate, scores higher on ingredient quality (89/100 versus 85/100), and adds sustained-release tablet technology designed to spread absorption across the day rather than delivering everything at once. It also includes vitamin C and avoids fillers like silicon dioxide and magnesium stearate, which matters to some buyers.
Budget is the sharpest dividing line here. At £16.07 for 60 capsules, Doctor's Best scores 83/100 for value — Igennus comes in at £25.99 for 90 servings but scores only 70/100 on value. If you have an MTHFR variant or suspected B12 deficiency and want active-form B vitamins without spending much, Doctor's Best is the practical pick. Igennus suits those who want the cleaner label, the sustained-release format, or who find the twice-daily Doctor's Best capsules cause burping or digestive discomfort — a complaint that comes up regularly in reviews, especially when taken on an empty stomach.
One thing worth flagging about Doctor's Best: bright yellow urine and occasional body odour from sweat are reported by several users. Harmless, but unexpected if you haven't seen it before.
Doctor's Best Fully Active B Complex earns its name by using genuine active forms throughout: Quatrefolic® 5-MTHF for folate, methylcobalamin at 1000mcg for B12, and riboflavin 5'-phosphate alongside standard riboflavin.
