NOW Supplements Vitamin B-1 (Thiamin) 100 mg is a straightforward, high-potency supplement designed for individuals looking to support their energy levels and nervous system. It's ideal for anyone with a B-vitamin deficiency, those on a vegan or vegetarian diet, or anyone seeking to improve their overall metabolic function.
The standout feature is the 100 mg dose of thiamin, which is significantly higher than the recommended daily allowance, making it effective for addressing deficiencies or supporting high-energy lifestyles. The inclusion of clean, allergen-free ingredients (vegan, non-GMO, soy-free) adds to its appeal, and the GMP certification ensures you're getting a quality product that meets strict manufacturing standards.
In terms of design and build, the tablets are simple and easy to swallow, and the bottle is sturdy and travel-friendly. While it lacks additional B-vitamins that often work synergistically, this is not a drawback if you're specifically targeting thiamin intake. The lack of artificial additives is a plus for health-conscious consumers.
A potential drawback is that some users might experience a mild upset stomach if taken on an empty stomach, which is common with high-dose B-vitamins. Also, the 100 mg dose may be excessive for those with a balanced diet, but it's generally safe as B-1 is water-soluble and excreted in urine.
Overall, NOW Vitamin B-1 is a reliable, affordable option for supporting nerve health and energy production. With its high potency, clean label, and trusted brand reputation, it's a smart choice for anyone needing a targeted thiamin supplement. Highly recommended for its quality and value.

Buying Guide: How to Choose the Right B-Vitamin Supplement
When shopping for a B-vitamin supplement, especially a single-entity B vitamin like B-1 or B-2, you need to consider more than just the label. Here are the key factors we used to evaluate these NOW products and that you should keep in mind for your own purchase.
1. Dosage and Potency
The amount of active vitamin in each serving is crucial. Both NOW products offer 100 mg of their respective B vitamins, which is a high dose, far exceeding the daily recommended intake for basic health. This level is often used for targeted support, but it’s important to consider your individual needs and whether you require a high-potency formula or a standard one. Always check the label for the exact amount per serving and whether it’s a tablet or capsule.
For most people, a high dose like 100 mg is safe, but it’s wise to consult a healthcare provider if you have any underlying conditions. The form of the supplement, whether tablet or capsule, can also affect absorption and convenience. For example, some people prefer capsules for easier swallowing, while others find tablets more cost-effective.
2. Brand Reputation and Certifications
Choosing a brand you can trust is non-negotiable. NOW Foods has been a staple in the natural products industry since 1968, and they are known for their rigorous quality control. Their GMP certification means every aspect of their manufacturing process is reviewed, and their in-house labs are ISO/IEC accredited for stability and potency testing. This gives you confidence that what’s on the label is actually in the bottle.
Additionally, look for third-party certifications like Non-GMO, Kosher, or Halal, which indicate a higher standard of ingredient sourcing. Both NOW products we reviewed boast Non-GMO and Soy Free designations, and the B-1 is also Vegan and Halal. These certifications can be a deciding factor for those with dietary restrictions or preferences.
3. Specific Health Benefits
Different B vitamins serve distinct roles in the body. Vitamin B-1 (thiamin) is essential for energy production and healthy nerve tissue, while B-2 (riboflavin) is a key cofactor for energy metabolism and supports the body’s natural detoxification systems. Consider your primary health goals: if you’re looking for nerve support, B-1 might be your priority; if you need help with energy and antioxidant protection, B-2 could be more suitable. Many people opt for a B-complex to cover all bases, but a single B vitamin can be beneficial for addressing a specific deficiency.
For a more comprehensive approach, you might also explore a full B-complex, but these individual options are perfect for those who want to control their intake of each B vitamin separately.

4. Value and Serving Size
Value isn’t just about the price tag; it’s about the cost per serving and the number of servings per container. Both NOW products come with 100 servings, which is a solid supply for a three-month period if taken daily. This makes them an affordable option in the long run, especially when you consider the high potency per serving. Always calculate the cost per serving to compare products effectively, but remember that quality should be your primary driver.
Beyond price, consider the serving size and whether it’s easy to split if you need a lower dose. Some supplements are scored for easy halving, while others are not. In this case, the B-1 is a tablet, which can be split, while the B-2 is a capsule, which cannot. Keep that in mind if you’re planning to adjust your dosage.
Final Thoughts
When it comes to supporting your energy and nervous system, both of these NOW supplements deliver on their promises. If you’re specifically targeting nerve health and carbohydrate metabolism, NOW Supplements, Vitamin B-1 100 mg is an excellent choice with its added vegan and halal certifications. On the other hand, if you’re looking to boost your energy metabolism and support your body’s detoxification pathways, NOW Supplements, Vitamin B-2 (Riboflavin) 100 mg offers a potent, allergen-conscious formula. Both are backed by NOW’s solid reputation, making them reliable additions to any supplement routine.
Frequently Asked Questions
What is the difference between NOW B-1 and B-2?
Vitamin B-1 (thiamin) is primarily involved in energy production and nerve cell function, while B-2 (riboflavin) is a coenzyme for energy metabolism and supports antioxidant defenses. Both are essential, but they serve different roles in the body. Choosing between them depends on your specific health goals.
Can I take NOW B-1 and B-2 together?
Yes, you can take them together, and it’s actually common to combine B vitamins since they work synergistically. Many people opt for a B-complex for convenience, but taking individual B vitamins allows you to adjust dosages as needed. Always consult with a healthcare provider to ensure it’s right for you.
Are there any side effects of taking high-dose B vitamins?
High doses of B vitamins are generally water-soluble, so excess is excreted in urine, but some people may experience mild issues like digestive upset or a harmless bright yellow urine (from B-2). At 100 mg, these products are safe for most adults, but it’s best to stick to the recommended dosage. If you have any concerns, talk to your doctor.
How long does it take to feel the effects of B vitamins?
Many people notice a difference in energy levels within a few days to a couple of weeks of consistent use, especially if they were deficient. However, individual responses vary based on diet and lifestyle. For a comprehensive approach to your wellness, you might also explore other supplements; for instance, learning about types of magnesium for men can complement your B-vitamin routine.
