Walk down the vitamin aisle and thiamine is one of those labels you probably skim past. It sits quietly on B-complex bottles, rarely gets its own spotlight, and most people could not tell you what separates one form from another. That is a problem, because thiamine comes in several forms and the one on the label decides how much your body actually puts to use.
Thiamine, or vitamin B1, is a water-soluble vitamin the body needs to convert food into usable energy. Some supplements use plain thiamine mononitrate or hydrochloride, while others use benfotiamine or TTFD, fat-soluble forms designed for better absorption. I looked at the Best Thiamine Supplements to find the ones with a clear dose per serving and a form worth the shelf space.
My overall pick for best thiamine supplements is the Life Extension Benfotiamine with Thiamine. It pairs a fat-soluble benfotiamine dose with plain thiamine in one capsule, so you get both forms without juggling two bottles. My top picks are just below.

- +240-count pouch supports a four-month routine

Key Facts
Detailed Review
Micro Ingredients packs 500mg of thiamine mononitrate alongside 50mg of benfotiamine into each 2-softgel serving, a combination that stands out from plain thiamine tablets. The softgels are built around an MCT oil base, which I see as a practical choice for anyone who prefers an oil-based delivery over a dry compressed tablet.
The 240-count pouch works out to roughly a four-month supply at the stated serving size, so it fits a daily routine without frequent reordering. The formula skips soy, dairy, and gluten, and the ingredients are screened for consistency.
Worth knowing before you buy: the two-softgel serving means a daily habit of four capsules if you follow the label, and the brand does not name a specific third-party certification program. I'd consider this for someone who wants a higher-dose B1 softgel with benfotiamine included.
This supplement provides 100 mg of benfotiamine per serving, a fat-soluble form of vitamin B1 noted for its bioavailability. The formula is non-GMO and gluten-free.
Pros
- +Higher-absorption benfotiamine form of vitamin B1
- +Straightforward single-ingredient formula
- +Non-GMO and gluten-free sourcing
- +Generous 120-capsule supply per bottle
Cons
- −No third-party certification like USP verified
- −Fat-soluble form may require dietary fat for optimal uptake
- −Lacks other B vitamins for broader support
Key Facts
Detailed Review
This product centers on a single, specific ingredient: 100 mg of benfotiamine per serving. Benfotiamine is a fat-soluble derivative of thiamine (vitamin B1), which the listing states may support levels faster and longer than the standard water-soluble form.
The serving is one vegetarian capsule, and the bottle contains a four-month supply at that frequency. I see this working best for someone seeking a targeted, high-dose B1 supplement from a reputable brand, with the understanding that benfotiamine's fat solubility means taking it with a meal could be beneficial.
A trade-off is the lack of a disclosed third-party certification for purity, though a Certificate of Analysis is available upon request. For my money, this suits a focused approach to B1 supplementation.
Vegan thiamine gummies delivering 500mg vitamin B1 per serving in a natural strawberry chewable, made in the USA in GMP-certified facilities.
Pros
- +500mg thiamine per serving in one chewable gummy
- +Vegan, gluten-free formula suitable for adults and kids
- +Natural strawberry flavor with no artificial junk
- +Made in USA in GMP-certified, FDA-registered facilities
Cons
- −500mg far exceeds typical daily B1 intake from food
- −Only 60 gummies per bottle, a 30-day supply at two daily
- −No specific third-party certification program named
Key Facts
Detailed Review
kindnature's B1 gummies deliver 500mg of thiamine per serving, a dose far above what most daily multivitamins provide. That matters if the goal is a concentrated B1 chewable rather than a broad B-complex. The format is a natural strawberry gummy, vegan and gluten-free, which suits adults and kids ages 4 and up who dislike capsules.
The main trade-off is the serving math: at two gummies daily, a 60-count bottle lasts about a month. The label states 500mg per serving, so anyone comparing this to a standard B-complex should note the difference in scale. I'd consider this for households wanting one chewable B1 option that works across age groups.
Worth knowing before you buy: the features name GMP-certified, FDA-registered US facilities and third-party lab review, but no specific certification program like USP or NSF is listed. For my money, this suits a family routine where a flavored chewable beats a pill.
This supplement delivers 600mg of benfotiamine, a fat-soluble form of vitamin B1, per two-capsule serving. The formula is third-party tested and made with non-GMO, vegan ingredients.
Pros
- +Substantial 600mg dose of benfotiamine per serving
- +Vegan capsule format with a broad allergen-free profile
- +Independent third-party testing on ingredient quality
Cons
- −Daily serving requires taking two capsules together
- −Fat-soluble format may require dietary fat for optimal absorption
- −No specific third-party certification program named for testing
Key Facts
Detailed Review
This product centers on a 600mg dose of benfotiamine per serving, a fat-soluble derivative of thiamine. That high, targeted dose in a fat-soluble form is its main distinguishing feature. The formula uses vegan capsules and excludes major allergens like gluten, dairy, and soy, which I see working best for those with dietary restrictions.
It's third-party lab tested, a practical step for verifying ingredient purity, though the specific certification program isn't disclosed. The main trade-off is the two-capsule serving size; you'll need to take both to get the full 600mg dose. I'd consider this a straightforward option for someone specifically seeking a high dose of this particular B1 form.
Nature Made Vitamin B1 100mg Tablets provide 100mg of thiamine per tablet in a 100-count bottle, USP Verified and gluten free.
Pros
- +USP Verified for quality and purity
- +100mg thiamine dose per tablet
- +Gluten free with no artificial flavors
- +100-day supply from one bottle
Cons
- −Only one active ingredient, not a full B-complex
- −No third-party testing beyond USP disclosed
- −Tablet form may not suit those preferring capsules
Key Facts
Detailed Review
Nature Made Vitamin B1 100mg Tablets deliver a straightforward 100mg of thiamine per tablet, with a 100-count bottle lasting 100 days at one tablet daily. The USP Verified mark is the detail I weigh most here, since it confirms the product meets a recognized quality standard for potency and purity. It is also gluten free and made without artificial flavors or preservatives, which keeps the formula simple for a daily routine.
The main trade-off is that this is a single-ingredient B1 supplement, not a full B-complex, so it suits someone targeting thiamine specifically rather than broad B vitamin coverage. I see this working best for a straightforward daily regimen alongside a meal, and the tablet format is easy to take with water.
For my money, this is a reasonable pick for anyone who wants a dedicated B1 product with a verified quality mark and no unnecessary extras.
Objective Nutrients Thiamax delivers 100mg of TTFD thiamine with magnesium in small, easy-to-swallow capsules. Made in the USA and non-GMO.
Pros
- +TTFD form may support cellular energy utilization
- +100mg thiamine dose per serving
- +Extra-small capsules for easy swallowing
- +Non-GMO and made in the USA
Cons
- −Only 60 capsules per bottle
- −Serving size not explicitly stated on label
- −No specific third-party certification program named
Key Facts
Detailed Review
Objective Nutrients Thiamax stands out for using TTFD thiamine, a form that may support cellular uptake better than standard thiamine. Each capsule delivers 100mg of thiamine with magnesium, and the extra-small size makes them easy to swallow for daily use.
I'd consider this for someone looking for a well-absorbed B1 option that fits a morning routine. The formula is non-GMO and made in the USA, with third-party review for purity. The main trade-off is the 60-capsule count, which may require frequent reordering if taken daily.
Worth knowing before you buy: the serving size is not explicitly stated, so I'd check the label for how many capsules equal one dose. Overall, I rate this a reasonable pick for those wanting a TTFD thiamine supplement with magnesium.
Deal Supplement Vitamin B1 delivers 500mg thiamine mononitrate plus 25mg benfotiamine per two-capsule serving, combining water- and fat-soluble forms in one capsule.
Pros
- +Dual-form formula pairs thiamine with benfotiamine
- +Third-party reviewed for quality assurance
- +240-capsule bottle yields 120 servings
- +Excludes eight common allergens including gluten and soy
Cons
- −Two-capsule serving may not suit once-daily routines
- −Benfotiamine dose at 25mg is modest relative to thiamine
- −No specific third-party certifier named on label
Key Facts
Detailed Review
Deal Supplement Vitamin B1 stands out for its dual-form approach: each two-capsule serving supplies 500mg thiamine mononitrate alongside 25mg benfotiamine, a fat-soluble derivative. That combination is designed to cover both water-soluble and fat-soluble thiamine pathways, which is a more targeted strategy than plain thiamine alone.
With 240 capsules per bottle, the serving size works out to 120 total servings, so a daily two-capsule routine lasts about four months. The formula is also third-party reviewed and excludes gluten, dairy, eggs, peanuts, soy, wheat, yeast, and tree nuts, which matters if you are managing multiple food sensitivities.
Worth knowing before you buy: the benfotiamine dose is modest at 25mg compared to the thiamine, and the two-capsule serving may not fit a once-daily habit. I'd consider this a reasonable pick for someone seeking a combined thiamine and benfotiamine formula in a large bottle.
Why You Should Trust Us
Nutrition Comparison does not run a testing lab, and I am not going to pretend otherwise. What I do is read labels closely, compare ingredient forms and doses across brands, and note where a product discloses third-party testing or a certification. Each product gets an NC Score built from those factors: how clear the serving size is, whether the form matches what the label claims, and how the formula fits a normal daily routine.

Final Thoughts
What matters most with thiamine is the form and the dose per serving, not the bottle size or the marketing on the front. A plain 100mg tablet and a 500mg benfotiamine blend serve different needs, and picking the wrong one for your routine is the most common way people waste money here.
For most people who want a straightforward daily option, the Life Extension Benfotiamine with Thiamine is my best overall pick. It combines benfotiamine with plain thiamine in a single vegetarian capsule, which suits anyone who wants both forms without tracking two separate products. If you are watching your budget, the Nature Made Vitamin B1 100mg Tablets, 100 Tablets is the value pick: a simple 100mg dose, one tablet daily, and a USP Verified mark on the label. It is a no-frills choice that fits a basic routine.
If you want a higher-dose option with both fat- and water-soluble forms, the DEAL SUPPLEMENT Vitamin B1 500mg covers that ground. And if you are comparing benfotiamine specifically, the benfotiamine supplement options break down how those formulas differ. The right pick here is really about matching the form to your routine, and once you do that, the label stops being confusing.
FAQs
What is the difference between thiamine and benfotiamine?
Benfotiamine is a fat-soluble form of vitamin B1, while plain thiamine is water-soluble. The fat-soluble form is generally absorbed more efficiently, which is why many higher-dose B1 supplements use it. Plain thiamine still works well for basic daily intake, and some formulas combine both forms to cover more ground.
Can you take thiamine with other B vitamins?
Thiamine is commonly taken alongside other B vitamins because they work together in energy metabolism. A B-complex or a standalone B1 capsule both fit that pattern. If you take a separate B-complex, check the label so you are not doubling up on the same dose from two products.
Do you need to take thiamine with food?
Taking thiamine with a meal is a common approach because it can be gentler on the stomach and may support absorption. Fat-soluble forms like benfotiamine are often paired with food for the same reason. If you notice any stomach discomfort, moving your dose to mealtime is a simple first step.
Is it better to take thiamine in the morning or at night?
Morning is the more common choice because thiamine supports energy metabolism, and some people find it stimulating later in the day. That said, timing is flexible for most routines. If you are managing a health condition or taking medication, check with your doctor before setting a schedule.
