Vitamin B1 Supplement Reviews

BulkSupplements Thiamine HCl Powder Review

OVERALL RATING 10
  • Editor’s Pick: Best thiamine hydrochloride supplement
  • Form: Powder
  • Doses per container: 1,000
  • Flavor: No flavor
  • Shipping: Free shipping on orders over $49.00 (contiguous US only)
  • Price and discounts: $21.96, discount available with subscription or when buying together with other products

First on our list, we have a promising thiamin product from BulkSupplements. The Thiamine HCl Powder can help with consistent thiamine delivery in larger doses, providing all of the essential B1 supplement benefits.

With 100 mg of thiamine per serving, and bonded with hydrochloride (HCl), this product has improved absorption rates, which is important to those who already have more severe thiamine deficiency problems and need a reliable product that will help them treat their disorder.

Furthermore, because it’s water-soluble, it can also be a great product for those who just want to keep their thiamine levels optimal without “overdosing” (which again, is almost impossible).

On the other hand, the powder might not be the most convenient and otherwise best form of vitamin B1 supplement for everybody, as dosing can get a bit difficult,

Apart from this, user reviews of the product are quite positive, with people praising it for being really helpful in fighting fatigue and improving eye health. Some reviewers mentioned that it does wonders in managing stress, while others were really satisfied with the purity of the product.

Simply put, Thiamine HCl Powder is one of the best natural thiamine supplements on the market.

PROS:
  • Powder form allows creating specific doses
  • Natural, with no additives
  • Great bundle options on the official website
CONS:
  • The powder form might not be ideal for everyone

Seeking Health Thiamin Review

OVERALL RATING 9.9
  • Editor’s Pick: Best B1 supplement for boosting energy levels
  • Form: Capsules
  • Doses per container: 120
  • Flavor: No flavor
  • Shipping: Free shipping, 60-day money-back guarantee
  • Price and discounts: $10.95, subscribers save 10%

Vegetarians who are looking for the best source of vitamin B1 at a low cost (and a subscription option) might find that Seeking Health’s Thiamin is a trustworthy product that’s bound to deliver the desired results.

The mild-potency capsules of 50 mg of thiamine per serving are great for better dose management, especially for those who require more thiamin throughout the day, as prescribed by their doctor.

As far as user reviews go, the majority of buyers were satisfied with the product stating that it gave them lots of energy. Some even said that considering the price, this is the best quality B1 product on the market.

And while the majority of the people will say that pure thiamine capsules are the best form of thiamine, there will always be those who prefer a little “more bang for their buck”. Namely, a handful of customers said that the brand’s TPP Thiamine lozenges were better as they were in active form and were better for people with thiamine deficiencies.

PROS:
  • Great for vegetarians
  • Pure product
  • Positive user reviews
CONS:
  • Some might prefer an alternative product from the brand

Country Life Vitamin B1 With Benfotiamine Review

OVERALL RATING 9.9
  • Editor’s Pick: Product with the best benfotiamine reviews
  • Form: VCaps
  • Doses per container: 60
  • Flavor: No flavor
  • Shipping: Standard shipping
  • Price and discounts: $21.39, frequent sales and a 5% off newsletter subscription bonus

This benfotiamine product also ranks pretty high on our list, and for a reason. For starters, it’s among the cheapest benfotiamine supplements on the list and apart from that, it also boasts some pretty nice features that make it a hard-to-pass deal for someone who wants to get the best from vitamin B1 supplementation.

We’ve already discussed that benfotiamine has the best thiamine supplement bioavailability (or at least, better than water-soluble options). Well, apart from that, this product is also a certified non-GMO supplement, good both for kosher and vegan users with recyclable packaging and energy-conscious manufacturing processes.

Furthermore, the manufacturer also claims that the raw materials and ingredients are all tested before creating the product, meaning that they are reliable and fresh throughout the product’s shelf life.

That all sounds good, but how does the product hold up in terms of online benfotiamine supplement reviews?

All in all, a lot of users are more than satisfied with this product. Some praise it for helping them improve their focus, while others mentioned that it helped a great deal with issues such as diabetic neuropathy.

On the flip side, others mentioned developing headaches from the product and other unwanted side effects.

Because of this, you should always consult your doctor before taking supplements.

PROS:
  • Unbeatable price
  • Improves focus
  • All-natural supplement
CONS:
  • Might cause headaches for some users

BulkSupplements Thiamine Mononitrate Review

OVERALL RATING 10
  • Editor’s Pick: Best large-package B1 vitamin supplement
  • Form: Powder
  • Doses per container: 2,000
  • Flavor: No flavor
  • Shipping: Free shipping on orders over $49.00 (contiguous US only)
  • Price and discounts: $42.96, 5% off for subscribers

If you’re looking for a straightforward and no-fuss deal, this is pretty much it—2,000 servings of pure thiamine mononitrate with at least 100 mg of vitamin B1 in each serving.

It might come as a surprise that this product ranks this low. Even though it’s pretty similar to the supplement on the top of our list, there are a few differences. First, it’s not HCI powder, meaning that absorption is a bit poorer, and it’s a synthetic form of thiamine. However, that’s not to say that it’s any less safe than the best natural supplement source of vitamin B1 that you can currently buy.

Quite the opposite, it’s still a pretty good product, and user reviews back that claim up.

More precisely, the majority of buyers felt the benefits of B1 supplementation while using Thiamine Mononitrate and stated that the powder is easy to mix with juices and drinks.

On the other hand, some said that they didn’t feel any major difference, or were dissatisfied because they didn’t get a scoop with the product, which made dosing more of an issue.

While it’s true that powders and vitamin B1 liquid supplements might be a bit harder to dose without a scoop or a dosing instrument, this didn’t seem to be a huge problem for the majority of buyers.

PROS:
  • Large container
  • Good price/quantity ratio
  • Pure B1 vitamin
CONS:
  • Some buyers dislike the fact that the main ingredient is synthetic

Nature's Plus Vitamin B1 Review

OVERALL RATING 9.7
  • Editor’s Pick: Best natural vitamin B1 supplement with high potency
  • Form: Tablets
  • Doses per container: 90
  • Flavor: No flavor
  • Shipping: Standard shipping
  • Price and discounts: $14.79, no current deals

If you’re looking for a high-potency thiamine product, then Vitamin B1 from Nature’s Plus is a supplement that probably deserves your attention. Delivering 300 mg of vitamin B1 in a single dose makes it one of the more potent products on our list.

Apart from all this, what else made us rank this supplement rank so high? Well, from a price vs potency standpoint, this might be the best low-cost thiamine supplement on the market. Furthermore, it ranked pretty well among users as well, who also praised it for its price and effectiveness ratio.

On the other hand, some users have complained about the fact that the product is a bit hard to syringe-feed, as the tablets crush okay, but the powder tends to turn cloggy and lumpy when coming into contact with water, becoming impossible to suck up.

Also, some have mentioned that the pills are too big, making them difficult to swallow.

While these problems can be bothersome, for most users, they probably won’t be an issue. Most will find that the tablets are the best form of thiamine supplement administration, as they enable the users to accurately dose their vitamin B1.

Lastly, it’s true that not everyone needs high-potency thiamine products. For those who just want to keep their levels in check, something with less B1 per serving should suffice to provide them with all the benefits of the vitamin.

PROS:
  • Great price/value ratio
  • 3 months of high-potency thiamine supplementation per bottle
  • Sustained release of vitamin B1
CONS:
  • Pills might be too big for some

Vitamatic Vitamin B1 Review

OVERALL RATING 9.6
  • Editor’s Pick: Best B1 vitamin containing 500 mg of thiamine
  • Form: Capsules
  • Doses per container: 120
  • Flavor: No flavor
  • Shipping: Standard shipping
  • Price and discounts: $13.99

For those who are looking for a very potent product, Vitamatic’s Vitamin B1 with 500 mg of thiamine per serving might be the real deal. One of the most potent products on our list, this supplement does its best to maintain energy levels and healthy heart function with a large amount of thiamine in every dose.

As we’ve already said, water-soluble thiamine capsules might not be the best supplement form of vitamin B1 for everyone as they have slightly weaker bioavailability than benfotiamine products. However, this product can be ideal for those who want to replenish their B1 levels with water-soluble options.

It also needs to be mentioned that the supplement is made with GMP standards in mind, so product purity and quality shouldn’t pose issues.

When looking at vitamin B1 supplement reviews, it becomes evident that people who were looking for a strong B1 product were quite satisfied with this Vitamatic supplement. On the other hand, pill size is quite a heated topic, with some people thinking that the pill is easy to swallow, and others claiming that the size of the pills is actually the biggest drawback of the product.

All in all, this product can be a great purchase for those who want to find all the B1 supplement benefits in a potent, yet simple package.

PROS:
  • Among the strongest B1 supplements on the market
  • Simple and effective product
  • Made in accordance with the highest GMP standards
CONS:
  • Pill size may be an issue for some buyers

Pure Encapsulations BenfoMax Review

OVERALL RATING 9.6
  • Editor’s Pick: Best benfotiamine supplement
  • Form: Capsule
  • Doses per container: 90
  • Flavor: No flavor
  • Shipping: Standard shipping
  • Price and discounts: $45.90

Like many similar high-quality supplements, BenfoMax contains benfotiamine, which is the fat-soluble relative of thiamine. Being lipid-soluble means that benfotiamine penetrates the nerve cells more easily, offering better bioavailability. 

For most consumers, these facts make benfotiamine a better option for treating vitamin B1 deficiencies than its water-soluble counterparts. When it comes to other possible benefits of benfotiamine, its nerve repair potential is currently being examined, implying it might find use in the treatment of neuropathy.

Unconfirmed benefits aside, Pure Encapsulations’ BenfoMax has been proven to be a good option for those who want to get their hands on a product with enhanced bioavailability and bioactivity.

Also, this product can be great for those who try their best to only use all-natural products. BenfoMax is a non-GMO product, free of wheat, eggs, nuts, artificial sweeteners, flavors, and colors, shellacs, coatings, preservatives, binders, and fillers. All these attributes make this product the best vitamin B1 for vegan buyers who are looking to reap the benefits of benfotiamine.

User reviews are generally favorable as most buyers praise the product for helping them overcome autoimmune issues, fatigue, and other problems related to low levels of vitamin B1. On the other hand, some actually got fatigued after starting to use the supplement, while one reviewer complained of changes in the urine odor.

Apart from these negative experiences, BenfoMax was practically uniformly praised as a good source of B1.

PROS:
  • Benfotiamine formula
  • 200 mg of benfotiamine per serving
  • You only need to take one capsule a day
CONS:
  • Some users experienced mild side effects

Source Naturals Coenzymated B1 Review

OVERALL RATING 9.7
  • Editor’s Pick: Best coenzymated B1 vitamin supplement
  • Form: Lozenges
  • Doses per container: 60
  • Flavor: Natural peppermint flavor
  • Shipping: Standard shipping
  • Price and discounts: $22.75, discounts offered with combo purchases

Coming in the form of already coenzymated B1 lozenges with natural and mild peppermint flavor for those who are tired of flavorless capsules and powders, Source Naturals’ Coenzymated B1 is a supplement that’s worth looking into.

“Already coenzymated” means that B1 is ready to act once it enters the body, which can be a great selling point for those who are looking to feel the immediate benefits of thiamine supplementation.

As it has only 13 mg of thiamine per lozenge, it could be the best way to supplement thiamine for those health-conscious users who already have almost adequate B1 levels and need just that little extra.

Vitamin B1 supplement reviews state that this product is great for those who have problems absorbing vitamin B1, and mentioned that it also helped them with pain management.

On the other hand, a few customers said that the product couldn’t effectively dissolve in water, while one user mentioned experiencing a negative reaction to mannitol and sorbitol.

Apart from that, this product can be a great thiamine source for most buyers.

PROS:
  • Fast-acting B1
  • Mildly flavored
  • Lozenges might be “friendlier” than capsules for some
CONS:
  • Sorbitol and mannitol may cause problems for some consumers

Life Extension Benfotiamine With Thiamine Review

OVERALL RATING 9.8
  • Editor’s Pick: Best thiamine supplement for arrhythmia
  • Form: Capsules
  • Doses per container: 120
  • Flavor: No flavor
  • Shipping: Free shipping on orders over $75.00
  • Price and discounts: $14.96, $10.00 off on signup and on orders over $75.00

For those who are looking for the “best of both worlds” i.e both water- and fat-soluble thiamine supplement, Life Extension’s Benfotiamine With Thiamine might be the best product to choose.

By providing “standard” and enhanced bioavailability at the same time, this product might be the best bet for most users who want to keep their heart health and brain function in check.

When looking at the product, it doesn’t really stand out from the long list of vitamin B1 supplements, and with 100 mg of thiamine/benfotiamine per serving, it’s not the most potent out of this bunch, however, the mixture of both water- and fat-soluble vitamins do make it stand out.

The available online reviews also make this product seem pretty credible, as most users experienced subsiding symptoms of neuropathy and improving energy levels along with mental focus.

On the flip side, some users mentioned that taking 4 capsules a day is a bit too much, while others complained of experiencing dizziness after one pill.

Also, some sources cite that there’s a connection between benfotiamine and hair loss, which might deter some users from benfotiamine products altogether (or at least make them invest in the best hair loss treatments as well, and use them congruently with B1 supplements).

PROS:
  • Lipid- and water-soluble
  • Great price
  • Vegan
CONS:
  • Might take a while before results become apparent

Ecological Formulas Allithiamine (Vitamin B1) Review

OVERALL RATING 9.7
  • Editor’s Pick: Best allithiamine product among natural thiamine supplements
  • Form: Capsules
  • Doses per container: 250
  • Flavor: No flavor
  • Shipping: Standard shipping
  • Price and discounts: $48.56, no discounts on product

This is the first allithiamine product on our list. If you’ve been wondering what allithiamine is, simply put, it’s a lipid-soluble B1, that manufacturers get from garlic and onions.

As a fat-soluble variant of thiamine, it also has better bioavailability than water-soluble options, making it all that much more inviting for buyers who want to get the most out of their vitamin B1 supplementation.

Because of its better overall availability in the body, this option might be a better, if not the best thiamine supplement for alcoholics and for other patients who have more severe cases of thiamine deficiency and need something potent to soothe their symptoms.

That being said, this 250-capsule product with 50 mg of allithiamine per serving can be a great option for those who need to fine-tune their dosing and spread it throughout the day.

On the review-end of things, most users are pretty satisfied with the product, praising it for helping them to improve mental focus and general energy levels.

On the other hand, some vitamin B1 reviews stated that users developed stomach problems.

All in all, we’re talking about a quality product here, which might be a steep deal financially for some, given that there are less expensive options on our list.

PROS:
  • Easy dosing
  • Great allithiamine source
  • Lots of positive reviews
CONS:
  • A bit on the pricier side

Finding the Best B1 Supplement (Buyer’s Guide)

After carefully reading everything about the best products on the market, it’s now time to learn a little more about vitamin B1 and the supplements based on it.

About B1

Finding the best B1 supplement starts with learning about this vitamin. This water-soluble vitamin (often referred to as thiamine, or thiamin) is a compound that enables the body to use carbohydrates more efficiently as fuel (energy). It’s important in metabolizing glucose and it also plays a crucial role in maintaining healthy heart, nerve, and muscle functions.

When it comes to getting enough thiamine, experts argue that the best source of vitamin B1 is food, such as grains, meat, and fish, yeast, nuts, whole grains, and pork.

Kale, asparagus, oranges, eggs, cauliflower, liver, and potatoes are also known to contain the vitamin, however, cooking, processing, and heating these foods can destroy thiamine.

Vitamin B1 Benefits

When talking about these compounds, we should also mention their potential health benefits. Thiamine helps prevent several complications in the body, including problems with the brain, nervous system, muscles, intestines, stomach, and heart. It can also help electrolytes enter and leave the muscles and nerve cells.

Taking an adequate thiamine supplement dose on a regular basis can also help prevent such diseases as beriberi. 

Also, thiamine treatments are prescribed for those who suffer from peripheral neuritis, a condition characterized by inflammation of the nerves on the outer part of the brain.

Thanks to its characteristics, athletes may also take B1 products, to help enhance their athletic performance.

The main vitamin B1 function is converting carbs, fats, and protein into energy. As such, B vitamins (especially vitamin B1 supplements) are essential for keeping the skin, hair, liver, and eyes healthy, not to mention, they keep the nervous system intact, along with promoting healthy brain function.

Lastly, B vitamins are often referred to as “anti-stress” vitamins as well, because they can help boost the immune system in stressful periods (the best vitamin B12 supplements may also help improve your mood).

Vitamin B1 Deficiency

One of the main reasons people look for a reliable B1 vitamin supplement is to combat vitamin B1 deficiency.

Those who eat a diet consisting mainly of white flour, processed carbohydrates, and white sugar might actually develop thiamine deficiency over time.

The first vague symptoms of the condition are usually irritability and fatigue, however, as the condition progresses, it can affect the brain, heart, and muscles as well.

To correct the deficiency, supplements are usually prescribed, taken orally.

More often than not, experts will agree that the best form of thiamine is undoubtedly food, because it’s widely available in our everyday diet, especially if we look for whole-grain, nuts, potatoes, legumes, and non-processed food options.

Furthermore, several sources cite that thiamine isn’t toxic, meaning, “overdosing” shouldn’t be a concern.

Apart from eating a poor diet, excessive alcohol consumption may also lead to thiamine deficiency (among other alcohol-related problems).

Beriberi (Severe Thiamine Deficiency)

When vitamin B1 deficiency progresses, patients may develop beriberi, a condition characterized by several heart, brain, and nerve abnormalities. Beriberi also has several forms.

  • Dry beriberi: When the best B1 vitamin foods and other sources are avoided for long enough, patients may develop dry beriberi, a condition mostly presenting itself through muscle and nerve abnormalities such as a prickling sensation in the toes, along with leg cramps and pain. Muscle atrophy and weakness may also occur.
  • Wet beriberi: The hearts of patients with wet beriberi usually start beating faster and pumping more blood. In return, the blood vessels dilate and the skin becomes moist and warm. Eventually, heart failure will set in if the condition goes untreated, as the organ isn’t able to keep working at such an elevated rate.
  • Brain abnormalities: The best thiamine supplement for alcoholics can also help combat this deficiency that can potentially harm the brain. Sometimes, these abnormalities present themselves without any symptoms at all.
    At other times, symptoms are triggered after something worsens the condition, like an alcoholic binge or when the patient is given carbohydrates intravenously. In the latter case, problems occur because the excess carbs only increase the body’s thiamine needs.
    These brain abnormalities are called the Wernicke-Korsakoff syndrome, and they have two distinctive parts. Wernicke encephalopathy can lead to confusion, apathy, eye problems, and eye paralysis. The other part, Korsakoff’s psychosis can cause confusion, memory loss, and confabulation.

With such severe consequences, no wonder most doctors will urge you to choose the best vitamin B1 supplement when you’re suffering from thiamine deficiency. 

Vitamin B1 Dosage 

According to the US guidelines, the recommended daily allowance taken orally should be 1.2 mg for men and 1.1 mg for women over the age of 18. Breastfeeding or pregnant women have a slightly higher RDA of the compound, at 1.4 mg daily.

When supplementing, dosages will mostly depend on your conditions. In the case of mild thiamine deficiency, 5 mg to 30 mg of the best thiamine supplements may help, however, in more severe cases, you might have to take as much as 300 mg daily.

Side Effects, Interactions, and Products to Look For

Generally, thiamine is considered nontoxic, however, experts from the US Food and Drug Administration (FDA) advise users to be cautious when buying supplements.

Not to say that these products are harmful, but as the FDA does not regulate supplements, the testing and standards aren’t as high as they are for pharmaceuticals. As such, some less reliable and reputable manufacturers can fabricate claims and manipulate nutrient contents.

So, to avoid buying faulty products, reading vitamin B1 reviews (such as this one) can be a huge help. Also, consulting with your doctor is essential. Lastly, you can learn more by reading different product labels, researching manufacturers, and looking for certificates and third-party lab test results to ensure that you’re getting the right product. 

As far as interactions go, tannins found in coffee and tea may interact with thiamin and make it harder to absorb. Also, chemicals in raw fish and shellfish may destroy thiamine and can lead to deficiencies if you eat them in large quantities.

Final Thoughts

Whatever your reason is for taking B1 vitamin products, hopefully, these vitamin B1 supplement reviews have helped you learn a bit more about this nutrient and make a decision regarding which product to use.

Whether you’re trying to improve your health and diet or trying to combat thiamine deficiency, it’s always important to let your doctor know about your intentions. With the help of a professional, you won’t just get the product that will suit your needs, but also a personalized program and diet regimen that will help you get the most out of what thiamine offers.

FAQs

What is the best B1 supplement?

The “best” will be slightly different for everyone, as each of us has different needs. Some of us will only look for thiamine-only products while others may seek a good B complex supplement (or the best multivitamins). Simply put, the best supplement of this kind is going to be the one that satisfies your needs the most and fits your budget the best.

What is the best form of thiamine?

Naturally, the best way to take thiamine would be through a balanced and healthy diet. That means that you should try to improve your diet by introducing thiamine-rich foods before even considering B1 supplements. This includes lean meats, dried beans, cereals, peas, fish, whole grains, and soybeans.

Is 50 mg of vitamin B1 too much?

According to several sources, the average RDA (recommended daily allowance) of vitamin B1 is 1.1 mg for women, 1.2 mg for men, and 1.4 mg daily for pregnant or breastfeeding women, taken orally. 

Some experts also recommend taking 50 mg of a B-complex supplement daily to get the full spectrum of B vitamins (along with riboflavin and niacin, to name a few).

Additionally, those who have more serious B1 deficiency problems (or are at a higher risk of developing said conditions) should always consult their doctor for the best dosages.

What are the side effects of too much vitamin B1?

Most medical sources cite thiamine as being nontoxic, thus safe, even at higher doses. 

On the other hand, other expert sources mention that larger doses (those exceeding 100 mg/day) may cause muscle relaxation or drowsiness. Furthermore, when injected, people may feel a slight burning sensation.

What is B1 vitamin good for?

In short, B1 helps prevent complications in the stomach, intestines, brain, heart, muscles, and nervous system. It can also positively affect the two-way flow of electrolytes to and out of muscles.

It can help prevent diseases such as beriberi and it’s used in the treatment of such conditions as peripheral neuritis (inflammation of the nerves on the outside of the brain).

Also, B1 may be prescribed to people with ulcerative colitis, diarrhea, and a low appetite. Coma patients may also receive thiamine injections.

Apart from these, the B1 vitamin might be used for other conditions such as:

  • Cataracts
  • AIDS
  • Canker sores
  • Glaucoma 
  • Cervical cancer
  • Stress
  • Heart disease
  • Kidney disease

Can I take vitamin B1 every day?

Yes, however, dosages will be highly dependent on your condition. If you want to combat mild thiamine deficiency, then your average dosage shouldn’t be higher than 5 mg to 30 mg a day. If you’re dealing with severe deficiency, doses can go up to 300 mg per day. 

For kidney damage, around 100 mg of thiamine three times a day for 3 months may help.

For menstrual cramps, 100 mg of thiamine with 500 mg of fish oil should be efficient if taken for up to around 90 days.

Is benfotiamine the same as vitamin B1?

Benfotiamine can be described as a relative of B1 or thiamine. Benfotiamine converts to thiamine once it’s in the body. 

However, the main difference is that benfotiamine is a fat-soluble form of vitamin B1, while thiamine is a water-soluble form. This means that benfotiamine manages to raise thiamine levels in the blood much better and remains in the blood flow much longer than its water-soluble variant.

All in all, you may find that for you, a benfotiamine product would be the best B1 supplement. However, if you suspect that you might suffer from thiamine deficiency, don’t hesitate and reach out to your doctor.
