Source Naturals Vitamin B-1 (Thiamine) 100 mg - 250 Tablets

Who Might Benefit from Thiamine Supplementation?

While most individuals get enough thiamine from food, certain groups may have higher requirements. Those who consume alcohol regularly often experience reduced thiamine absorption. Older adults, people with gastrointestinal conditions such as Crohn’s disease or coeliac disease, and those on highly processed diets may also need more. Vegans and vegetarians can consider supplementation because some plant sources provide less absorbable thiamine than animal products. Always consult a healthcare professional before starting any new supplement regimen.

What is Thiamine?

Thiamine, also known as vitamin B1, is an essential water-soluble vitamin that plays a critical role in converting carbohydrates into energy. It is a key component of the Krebs cycle, where it helps generate ATP—the primary energy currency of your cells. Beyond energy metabolism, thiamine supports normal nervous system function by aiding in the production of neurotransmitters and maintaining myelin sheaths. Because the body cannot store thiamine for long, regular dietary intake or supplementation is necessary to maintain optimal levels.

Health Benefits of Thiamine

Thiamine supports overall wellness in several ways. It helps the body metabolise carbohydrates, some amino acids, and alcohol, making it important for maintaining energy levels throughout the day. Additionally, thiamine contributes to healthy nerve function and helps support normal heart function. By promoting efficient energy production, it may help reduce feelings of fatigue when combined with a balanced diet. These statements have not been evaluated by Health Canada.

How to Choose a Thiamine Supplement

Thiamine supplements come in several forms: thiamine HCl (the most common and well-studied), thiamine mononitrate (less hygroscopic, often used in tablets), and benfotiamine (a fat-soluble derivative that may offer enhanced absorption for nerve health). Source Naturals Vitamin B-1 uses thiamine HCl in a straightforward 100 mg tablet—a dose suitable for daily maintenance. The brand has been manufacturing supplements in the USA since 1982, adhering to current Good Manufacturing Practises (cGMPs). For those seeking a trusted, straightforward option, Source Naturals offers over 40 years of quality assurance.

As with any supplement, consult with a healthcare provider to determine the appropriate dosage for your specific needs.
