What Does Klean B-Complex Do?
This well-formulated B-complex supports energy, cardiovascular health, and athletic recovery with research-backed active forms and effective dosages for most vitamins. However, the 50mg B6 exceeds safe long-term limits, posing neuropathy risk, though overall safe for short-term use in healthy adults.

Overview
•All B vitamins in this formulation are water-soluble with low toxicity risk; dosages for B12, niacinamide, biotin, and pantothenic acid are well within safe limits per NIH guidelines.
•Vitamin B6 at 50 mg exceeds the 2023 EFSA UL of 12 mg/day, potentially causing peripheral neuropathy with long-term use, though risk is lower than at higher doses (>100 mg).
•No significant drug interactions specific to this product, but high B6 and B12 may interact with anticonvulsants or metformin; consult healthcare provider if on medications.
•Safe for healthy adults and athletes; medium caution for pregnancy/nursing due to high B6—consult professional; not recommended for children without guidance.
•Gluten-free and non-GMO with no common allergens; NSF Certified for Sport ensures quality and minimal contamination risks.
•Short-term use is low risk, but monitor for B6-related nerve symptoms with prolonged daily intake; excess vitamins are generally excreted in urine.
