Symptoms of Vitamin B1 Deficiency Are Common

Fatigue, nerve pain, brain fog, muscle pain, and muscle fatigue are all common manifestations of vitamin B1 deficiency.

Vitamin B1 deficiency is a common consequence of gluten/grain sensitivity. Lack of this important B vitamin is often times responsible for continued health problems even when adhering to a gluten/grain free diet.

Vitamin B1, also known as thiamin is a water soluble B vitamin. It aids in the production of energy in all tissues in the body but more is used in the heart and skeletal muscle. Additionally it is necessary for the body to produce the neurotransmitter (chemical used by the nervous system and brain) acetylcholine.

Signs & Symptoms of Vitamin B1 Nutrition Deficiency Include:

Congestive Heart Failure
Tachycardia (increased heart rate)
Loss of appetite
Memory loss
Muscle wasting

Drugs, medications, or additives that may deplete or interfere with Vitamin B1 metabolism:

Diuretics used to lower blood pressure
Seizure Medications

    Thiamine, also known B1, really helps to turn food into energy and to keep the nervous system healthy. It’s in my B complete from DR. Osborne, but it really helped me by taking the extra B1.
