Thiamine (Vitamin B1) functions

Vitamin B1 is an essential, water-soluble vitamin. It helps with processing food into energy and is needed by every tissue in the body,

Thiamine dosage

The Nutrient Reference Value (NRV) is around 1.2mg per day. In every dose of the Heights Smart Supplement there is 30mg (equal to 20 bowls of fortified cereal or 100 mussels), this is 2727% the NRV. The NRV is really the minimum amount and higher doses have been shown to be beneficial. There are also no negative side effects from taking this higher dose.

This is why we choose to include a higher dose of thiamine to make sure you are getting all the benefits from the vitamin B1.

Thiamine research

Untreated thiamine deficiency, (although this is rare) could result in delirium and brain damage and higher risks of depression. It’s also being tested, with promising results on the cognitive function of Alzheimer’s patients.

Our own research found higher thiamine deficiency than we expected when we tested for it.

What does thiamine do for the brain?

Thiamine is needed for normal brain and nervous system function, and could play an important role in mental health.

  • Used by every cell in the body 

  • Could play an important role in mental health
