GNC Vitamin B1 300mg - 100 Vegetarian Tablets

Who Might Need Thiamine Supplementation?

Certain people may have higher thiamine needs. If you drink alcohol regularly, have digestive issues like Crohn’s or coeliac disease, follow a vegan diet, or eat a lot of processed foods, you might not be getting enough. Athletes and active folks also require more to fuel their energy metabolism. Thiamine is water-soluble, so your body doesn’t store it — you need a steady supply from food or supplements.

Key Benefits of Thiamine

Thiamine (vitamin B1) is essential for turning carbs, fats, and proteins into usable energy. It also helps maintain the myelin sheaths around your nerves, supporting nerve function. Some research suggests it may contribute to normal heart function and cognitive health as well.

What Is Thiamine?

Thiamine, or vitamin B1, is a water-soluble vitamin that acts as a coenzyme in carbohydrate metabolism. It’s crucial for nerve and muscle function. Because your body can’t store it, regular intake is necessary — either through diet or supplements.

How to Choose a Thiamine Supplement

Look for a well-absorbed form like thiamine hydrochloride (HCl). This GNC product gives you 300 mg of thiamine HCl per tablet — a strong dose for targeted support. The tablets are vegetarian, gluten free, kosher, and free from artificial colors, flavours, and preservatives. Third-party testing ensures quality.

Recommended Dosage and Usage

For general health, the recommended dietary intake (RDI) for thiamine is about 1.1–1.2 mg per day. Supplementary doses typically range from 50–100 mg up to 500 mg for specific needs. This 300 mg serving is considered high-dose, so chat with your healthcare professional before starting.
