Product Description: Supplement Energy Production Support Vitamin B-1 (thiamine) is essential for the metabolism of carbohydrates, some amino acids, and alcohol. It is also necessary for the production of the neurotransmitter acetylcholine and the detoxification of alcohol and lactic acid (a byproduct of intense exercise). Thiamine plays a key role in the production of energy and ATP via the Krebs cycle reaction. A high-carbohydrate diet, intense physical exercise, or chronic alcohol consumption can increase physiological vitamin B-1 needs.
