High Vitamin B1 (thiamine): what it means
A Vitamin B1 (thiamine) result above the normal range is considered high. Here is what a raised Vitamin B1 (thiamine) can point to, and when it is worth discussing with a doctor.
Reference range: ~70–180 nmol/L; deficiency is important in alcohol excess and malnutrition — where it can cause a treatable brain emergency (Wernicke's)

- Supplementation — the usual reason for a high level; thiamine is water-soluble and excess is generally not harmful.
When to discuss with a doctor
Thiamine deficiency is important not because it is common but because it is dangerous and completely treatable. It should be considered — and treatment often given without waiting for the test — in anyone at risk (alcohol dependence, malnutrition, persistent vomiting, after bariatric surgery) who develops confusion, unsteadiness, eye-movement problems, unexplained heart failure or nerve symptoms. Wernicke's encephalopathy is a medical emergency treated with urgent thiamine. A crucial safety rule is that glucose should not be given to an at-risk person before thiamine, as it can trigger the condition. Mediora.AI can flag the context and related nutrient deficiencies, but suspected thiamine deficiency in an at-risk person is treated promptly by a doctor, often before the level returns.
