Key Benefits of Thiamine

Thiamine (vitamin B1) is essential for converting carbohydrates into energy and supporting normal nerve function. It helps your body metabolise food into fuel, which can be especially helpful during periods of increased physical activity or mental demand. NOW Vitamin B-1 provides 100 mg of thiamine (as thiamine HCl) per tablet, with a 4-pack giving you 400 tablets in total for consistent daily use.

This product is a natural health product. Health Canada approved claims include: Helps the body to metabolise carbohydrates and supports normal nerve function. Always read and follow the label directions. Consult your healthcare practitioner before use if you are pregnant, breastfeeding, or have a medical condition. Do not exceed recommended dose.

Who Should Consider a Thiamine Supplement?

While a balanced diet provides thiamine from whole grains, pork, fish, and legumes, certain people may need extra support. Older adults, those who regularly consume alcohol, individuals with digestive conditions like Crohn’s or ulcerative colitis, and people following vegan or vegetarian diets often have higher requirements or reduced absorption. Athletes and active individuals may also benefit from thiamine for energy metabolism. As with any supplement, assess your diet and speak with a healthcare professional to see if thiamine is right for you.

What is Thiamine?

Thiamine, also known as vitamin B1, is a water-soluble vitamin that plays a critical role in how your body uses energy. It acts as a coenzyme in metabolic processes, helping unlock fuel from the foods you eat. Without enough thiamine, energy production slows and nerve function can suffer. NOW Vitamin B-1 is a straightforward way to ensure you get this essential nutrient every day.

How to Choose a Thiamine Supplement

Thiamine HCl (hydrochloride) is the most common and well-absorbed form, found in this NOW supplement. Thiamine mononitrate is another option but is less moisture-resistant. For targeted nerve support, benfotiamine (a fat-soluble derivative) offers better bioavailability, but that’s not the form here. Dosage matters: a typical maintenance dose is 25–100 mg daily. At 100 mg per tablet, this product suits moderate to higher needs. The 4-pack delivers excellent value and convenience. NOW Foods is a trusted brand with GMP-certified manufacturing, and this product is free from soy, milk, and sugar.

Recommended Dosage and Usage

Take 1 tablet daily with a meal. Each tablet provides 100 mg of thiamine. Don’t exceed the suggested dose unless directed by a physician. Since thiamine is water-soluble, extra amounts are usually excreted. Always consult your healthcare provider before starting a supplement if you are pregnant, nursing, or have a medical condition.
