Does the test detect vitamin deficiencies or absorption problems?

Updated on

No. The test does not measure your vitamin levels or how your body absorbs vitamins. The report may describe microbial genes involved in the synthesis or metabolism of certain vitamins, but their presence does not indicate how much is produced or absorbed, or whether you have a deficiency.

If you suspect a deficiency, consult your doctor, who will assess your diet, symptoms and any tests needed before recommending supplements.
