Vitamin B1

Vitamin B1 - Thiamine

 Benefits of vitamin b1

Thiamine (Vitamin B1) is an essential vitamin that your body and mind use, particularly the nervous system, heart, and brain. It is essential because all tissues in the body require B1 in order to function properly.

Interestingly, thiamine was the first of the B-complex family to be discovered, hence the name B1. Thiamine is water-soluble and helps heavily in energy production, enhances the body’s ability to withstand stress, maintains healthy nervous and cardiovascular functioning and helps turn food into energy.

Our body concentrates the use of vitamin b1 on the areas of the body that are the most metabolically active (meaning they use a lot of energy). As the brain uses more energy than any other organ, it heavily relies on vitamin b1 to ensure the conversion of food into energy. 

Due to the many benefits of thiamine we have used 200% of Australia's Recommended Dietary Intake of vitamin B1 in all Savvy products.

Thiamine Improves Energy Production, Mood and Alertness

Thiamine improves mood, energy and alertness

The body needs thiamine to make adenosine triphosphate (ATP) which is the body’s main energy-carrying molecule. This is a molecule that is responsible for transportation of energy within cells. Thiamine increases mood, energy, and alertness.

“The Max Stress B [B1,2,3,6,12 combination]  formula showed modest improvements in mood and mental health according to the BDI, BAI, and SF-36, making our findings consistent with the prior studies. Thus, our study shows that a high quality, whole-food dietary supplement may offer an opportunity for adults with depression to improve mood symptoms and quality of life.”

“This was a 4-week randomized placebo-controlled double-blind study to assess augmentation of open tricyclic antidepressant treatment with 10 mg each of vitamins B1, B2, and B6 in 14 geriatric inpatients with depression. The active vitamin group demonstrated significantly better B2 and B6 status on enzyme activity coefficients and trends toward greater improvement in scores on ratings of depression and cognitive function”

This literature review focuses on the neurological and psychological effects of thiamine deficiency. The review states that the deficiency of the vitamin causes mood changes like agitation, confusion and generalized malaise and the administration of the vitamin produced a positive mood in elderly and young individuals.

 

Smith, Taryn J., et al. ‘Thiamine deficiency disorders: a clinical perspective.’ 2020. [Link]

 

This review article finds a strong correlation of thiamine deficiency with disruption of energy in the body. The mechanism of energy deficiency is by reduction of the enzymes that are supplied to the Krebs cycle to produce ATP. A decrease in the energy in the body could lead to chronic energy deficiency that can cause malnutrition and weight loss. Neurologically, the deficiency can cause energy disruption to the neurons and increased oxidative stress, causing abnormalities in the blood-brain barrier.

The research study identified the antidepressant properties of thiamine at 200mg/kg/day for 2 weeks that regulated anti-oxidant, anti-stress and anti-inflammatory properties and reduced floating behaviour in mice. This was due to the mechanism of enhancement of the protein carbonyl levels in the brain, thereby improving the oxidation processes.

The literature review summarizes that the deficiency or insufficiency of Thiamine can cause depression, since the vitamin can result in malfunction in the synthesis of the required neurotransmitters, leading to depression. Other mechanisms includes induction of oxidative stress, leading to decreased hippocampal volume and damage in the neurons. A dose of 10 mg thiamine for 6 weeks led to a reduction in the depression symptoms in the elderly and a dose of 50 mg/day for 2 months improved the energy status and clear-headedness in young women.

This literature study summarizes that there is a direct correlation between thiamine deficiency, depression and major depressive disorders. The review also mentions that a 12 week, randomized, double-blind clinical trial effectively improved depression when Thiamine was administered for 6 weeks.

 

Thiamine boosts immunity and resistance to stress

Thiamine protects against stress

 

Vitamin B1 is sometimes called an “anti-stress” vitamin because it may improve immunity and also enhance the body’s ability to cope with stress.

The results of the study are consistent with two previous studies examining…supplementation of a B multivitamin.”

Administration of thiamine restored the activity of mitochondrial respiration and prevented neuroinflammation. It was also seen to reduce Endoplasmic Reticulum related stress, the occurrence of which can lead to neurodegenerative diseases.

 

Thiamine supports optimal mental performance through helping with the development of the myelin sheath

 

Thiamine boosts mental performance

 

Vitamin B1 helps with the development of the myelin sheath, which is a coat that wraps around nerves to protect them.

Myelin Sheath

The myelin sheath is an important part of the nervous system and is vital for optimal cognitive function. Myelin allows signals to travel faster, which can make everything in the brain work better.

Myelin controls the speed of impulse conduction through axons, and the synchrony of impulse traffic between distant brain regions is critical for optimal mental performance and learning.
