Best Thiamine (Vitamin B1)

Thiamine, also known as vitamin B1, is part of the vitamin B complex family. Mainly known for its role in a healthy nervous system and cardiovascular functionality, it also has a plethora of other benefits. (See Reference 1)

Thiamine is not stored in the body, so a steady intake of it in the diet or by supplementation is necessary. The skeletal muscles, heart, liver, kidney, and brain all rely on thiamine.

Here are some of the most important benefits of thiamine:

Health Benefits of Thiamine

Stress

Vitamin B1 is sometimes referred to as the “anti-stress” vitamin. Chronic stress has been shown to deplete B vitamins, yet supplementation with B vitamins can decrease stress levels. (See Reference 2)

One study found that thiamine supplementation reduced stress-induced physiological symptoms, indicating that it could be used to help with stress relief. (See Reference 3)

Heart Function

Thiamine is required for the production of the neurotransmitter acetylcholine, (See Reference 4) which means thiamine is good for your heart. Acetylcholine is essential because it plays a crucial role in the contraction of your muscles, including cardiac (heart) muscle).

Deficiency in thiamine could cause a decreased heart rate. One study that induced thiamine deficiency in rats showed that as a thiamine deficiency develops, the heart rate drops. Slowed heart rate can have further complications such as dizziness and fatigue.

Individuals with chronic alcoholism are even more at risk of thiamine-related heart failure because of decreased intake, absorption, and storage.

Athletic Performance

Thiamine is widely used by athletes as a dietary supplement to improve athletic performance.

A study looking at the effects of thiamine supplementation on endurance athletes found that thiamine intake during exercise decreases lactate and ammonia concentration by benefiting the way your body processes carbohydrates.

Lactate and ammonia build up during exercise, and as their levels increase, recovery slows down. Hence, thiamine supplementation helps athletes recover faster. Furthermore, those who have a highly physical lifestyle, such as athletes, need more thiamin (and other vitamins) than the recommended daily intake. Because their needs are higher, they are more susceptible to deficiency.

Fatigue

A common symptom of thiamine deficiency is increased tiredness and lack of energy. (See Reference 8) Several studies have linked thiamine deficiency to fatigue. (See Reference 5)

Fatigue is complicated in that it has a variety of potential causes. (See Reference 6) Vitamin deficiencies such as thiamine are often overlooked. Thiamin deficiency could contribute to fatigue, as it is an essential component of the process by which our body extracts energy carbohydrates from food. (See Reference 7) A deficiency in thiamin slows this process. (See Reference 6)
