B complex

别名: B vitamin complex

A B complex contains all or most B vitamins (B1, B2, B3, B5, B6, biotin, folate, B12) in one tablet. It suits restricted or plant-based diets and periods of higher demand, but quality depends heavily on the forms and doses on the label.

用途

Normal energy metabolism, nervous system and reduced tiredness – strong evidence for the individual vitamins (EFSA)
Lowering homocysteine (via B6, folate and B12) – moderate evidence
Less stress and better mood in healthy people – weak evidence

剂型及区别

standard B complex (100 % NRV)

doses around recommended intake – suitable for long-term use

forte or high-dose

doses well above needs; watch B6 and niacin in particular

with active forms (methylfolate, methylcobalamin, P5P)

more expensive, advantages for most people are not clearly shown

effervescent and chewable tablets, children's versions

convenient, but check sugar, sweeteners and age-appropriate dosing; PABA is not a vitamin

何时服用

In the morning or at lunch with food – in some people evening use may disturb sleep.

适合搭配

Magnesium, vitamin C.

不宜同服 / 需错开

Do not combine with other products containing B6, niacin or biotin to avoid exceeding limits.

注意事项

High-dose biotin in a B complex can distort lab tests – tell your doctor before a blood test. If you take medicines (e.g. for epilepsy, Parkinson's disease, methotrexate) or are pregnant, consult your doctor.

安全性

Respect EFSA limits especially for vitamin B6 (12 mg/day), folic acid (1000 µg/day) and nicotinic acid (10 mg/day); otherwise do not exceed the label dose.

实用建议

For long-term use choose a B complex with doses close to 100 % NRV – higher doses are not automatically better.
