That is how you might feel if you were severely deficient in any of the B-complex vitamins. Vitamin B1, along with B2, B12 and niacin are essential nutrients that play important roles in energy production, particularly in the metabolism of carbohydrates, fats and proteins. Without sufficient B1, you would feel weary, fatigued, and find it hard to function normally. The B vitamins are in a family of nutrients called coenzymes that help enzymes perform essential chemical reactions. This helps energy production, but also reactions critical to the function of neurotransmitters, hormones, digestive enzymes, mineral metabolism, and many more. Vitamin B1 helps to support the health of the central nervous system, cardiovascular system, pulmonary system, immune system and muscle function, which is why it is considered essential. ## Features - DAILY ENERGY SUPPORT: Easy-to-swallow high-potency thiamine tablets for adults 18+ to take once daily, preferably with food, as a dietary supplement - PURE THIAMINE (B1): Our potent formula delivers 250 mg of pure thiamine (B1) to support nervous system function and help convert food into energy - BENEFITS: Vitamin B1 is part of a coenzyme family that assists enzymes in crucial chemical reactions, supporting the health of the central nervous, cardiovascular, pulmonary, & immune systems - CLEAN INGREDIENTS: Soy & sodium free, with no added starch, wheat, corn, yeast, egg, artificial colors or flavors, gluten, fragrance, & preservatives - TRUSTED FOR OVER 50 YEARS: Mason Natural has produced quality vitamin supplements for over five decades, adhering to cGMPs (current Good Manufacturing Practices) and US guidelines with rigorous testing & inspections ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0050NMR9O | | Age Range Description | Adult | | Allergen Information | Soy Free | | Best Sellers Rank | #15,608 in Health & Household ( See Top 100 in Health & Household ) #18 in Vitamin B1 (Thiamine) Supplements #1,425 in Sales & Deals | | Brand | MASON NATURAL | | Brand Name | MASON NATURAL | | Color | No Color | | Customer Reviews | 4.6 out of 5 stars 3,442 Reviews | | Diet Type | Vegetarian | | Dosage Form | Tablet | | Flavor | Unflavored | | Global Trade Identification Number | 00311845056610 | | Item Dimensions | 2 x 2 x 4.1 inches | | Item Form | Tablet | | Item Highlight | 250 mg high-potency thiamine to support energy production, normal metabolism & nervous system function | | Item Weight | 2.9 ounces | | Manufacturer | Mason Vitamins | | Manufacturer Part Number | B002VPE80K | | Model Name | NATURAL, Vitamin B-1 Thiamine Tablets, 250 Mg, 100-Count Bottle, Dietary Supplement Supports Energy Production and Healthy Metabolism, Helps Break Down Fats and Protein | | Model Number | B002VPE80K | | Number of Items | 1 | | Primary Supplement Type | Multivitamins | | Product Benefits | Energy Management | | Special Ingredients | Thiamin (Vitamin B1) | | Specific Uses For Product | Energy Health | | UPC | 311845056610 | | Unit Count | 100 Count | ## Product Details - **Brand:** MASON NATURAL - **Diet Type:** Vegetarian - **Flavor:** Unflavored - **Item Form:** Tablet - **Primary Supplement Type:** Multivitamins ## Images ![MASON NATURAL Vitamin B1 Thiamine 250 mg, Support Energy, 100 Day Supply - Image 1](https://m.media-amazon.com/images/I/71SW29wcvaL.jpg) ## Available Options This product comes in different **Unit Count** options. ## Frequently Bought Together - MASON NATURAL Vitamin B-1 Thiamine 250 mg, 100 Day Supply Dietary Supplement, Easy-to-Swallow Tablets, Support Energy Production & Healthy Metabolism - Nature's Bounty Vitamin B6 100mg Tablets - Supports Energy Metabolism & Nervous System Health, 100 Ct - Nature Made Vitamin B12 1000 mcg, Dietary Supplement for Energy Metabolism Support, 150 Softgels, 150 Day Supply --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/11164054-mason-natural-vitamin-b1-thiamine-250-mg-support-energy-100](https://www.desertcart.co.za/products/11164054-mason-natural-vitamin-b1-thiamine-250-mg-support-energy-100) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-20*
