Buying guide and FAQs
What to compare
Amounts vary a lot between products, so read the full table rather than the name. Methylated formulas use forms such as methylfolate and methylcobalamin. Capsules and tablets are the most common, with liquids and gummies also available.
Is there a limit on vitamin B6?
The NHS advises not taking more than 10mg of vitamin B6 a day in supplements unless a doctor recommends it. Many B complex products contain more, so check the label.
Why does my urine turn bright yellow?
This is a common and harmless effect of riboflavin (vitamin B2).
