Questions we could help with
Real questions from people like you, and how a B vitamins blood test can help answer them.
Could mood swings be linked to my nutrition?
B12 and folate support the synthesis of serotonin and dopamine. Low levels can affect mood.
Why does my skin look dull?
Folate supports cell renewal and tissue repair. Low levels slow regeneration and affect skin vitality.
Why am I always tired?
A low vitamin B12 level can contribute. The test checks these markers so you can take targeted action.
