High-Potency B1, at the Dose That Actually Matters.

Vitamin B1 (Thiamine) is an essential nutrient your body can't make on its own. It's a critical coenzyme in how your body converts carbohydrates into cellular energy (ATP) — the fuel every cell, including your brain and nerves, runs on.†

Here's the gap: the RDA for B1 is just 1.1-1.2mg — the minimum to prevent classical deficiency. But B1 is water-soluble, meaning your body doesn't store it. Stress, sugar, caffeine, and processed foods can all increase how quickly it's used up. The minimum isn't the same as optimal.†

That's why we formulated at 500mg. A high-potency dose for people who want real B1 support — not the 1-5mg buried inside a generic B-complex. Pure thiamine, water-soluble, with no established upper limit (excess is simply excreted).†

It supports normal energy metabolism, healthy nervous system function, and everyday cognitive support — the foundational roles thiamine plays in the body, every day.†

A gummy you'll actually take. The high-potency dose. For your everyday energy, focus, and nervous system support.†

ONE VITAMIN. ONE PURPOSE. HIGH-POTENCY.

Why 500mg, and Why It Matters.

Pure thiamine at a high-potency dose. Not a token amount buried in a B-complex. That's the difference between a label and a real B1 supplement.†

Thiamine (Vitamin B1) — 500mg

High-potency pure thiamine. An essential coenzyme in carbohydrate metabolism — helping your body convert food into cellular energy (ATP). The dose researchers and clinical settings actually use, not the 1.2mg RDA minimum.†

Why 500mg, Not 1.2mg

The RDA is the minimum to prevent classical deficiency — not the amount for optimal everyday support. Thiamine is water-soluble with no established upper limit. Your body uses what it needs and excretes the rest.†

Energy Metabolism

Thiamine is a required cofactor in the enzymes that turn carbohydrates into ATP — the energy currency of every cell. Supports normal energy production throughout the body.†

Nervous System Support

B1 supports normal nervous system function and healthy nerve signaling. It's one of the foundational nutrients for everyday cognitive and nervous system wellness.†

Clean Gummy Format

Pectin-based (vegan, no gelatin). Naturally flavored strawberry. No artificial colors, no synthetic fillers, no proprietary blends. Just 500mg of pure thiamine in a gummy you'll actually remember to take.†

THE SCIENCE

Why 500mg? Because the Minimum Isn't the Optimum.

The RDA is the bare minimum to prevent deficiency. Here's why a high-potency dose makes sense for everyday energy and nervous system support — and why thiamine is so well-tolerated.†

Energy Metabolism

Thiamine is a critical coenzyme in carbohydrate metabolism — helping your body produce ATP, the energy currency every cell runs on. Supports normal energy production.†

Nervous System Support

B1 plays a role in normal nerve signal transmission and nervous system function. One of the foundational nutrients for everyday nervous system wellness.†

Cognitive Support

The brain is one of the most energy-hungry organs in the body, and thiamine fuels cellular energy production. Adequate B1 supports normal focus and everyday cognitive function.†

Water-Soluble & Well-Tolerated

Unlike fat-soluble vitamins, B1 doesn't accumulate in the body — excess is excreted in urine. No established upper limit, so 500mg sits well within the range used in research and daily supplementation.†

WHY KINDNATURE B1

Most B1 supplements cap at 100mg, or bury thiamine inside a B-complex at 1-5mg — token amounts. We deliver a straight 500mg of pure thiamine. No unnecessary fillers, no confusing blends. Just high-potency B1 your body can actually use for everyday energy and nervous system support. If you've researched your way to B1, you're in the right place.†

WHAT OUR CUSTOMERS SAY

Trusted by people who actually read the labels.

Megan T. Verified

Added these to my morning routine a couple weeks ago and I genuinely look forward to them - the strawberry flavor is great, nothing artificial tasting. Feeling good about having a real dose of B1 in my day instead of the tiny amount in my old multivitamin.

Chris R. Verified

I hate swallowing pills so a B1 gummy at an actual high dose is exactly what I wanted. Easy to take, no aftertaste, and I'm on subscribe now so I never run out. Simple and does what it says.

Sarah K. Verified

I take these alongside the B2 gummies from KindNature and like having both as part of my daily routine. Love that they're clean and vegan - no weird fillers or aftertaste. Would be 5 stars if the bottle were a little bigger.

James P. Verified

Bought for myself but my teenager started stealing them lol. Now we share a bottle. 500mg is genuinely hard to find in a gummy - most are 100mg or less. This is the real dose, which is why I bought it.

Frequently Asked Questions

What does Vitamin B1 (Thiamine) do?

Thiamine is an essential nutrient that helps your body convert carbohydrates into usable cellular energy (ATP). It also supports normal nervous system function. It's one of the foundational B vitamins for everyday energy and nervous system wellness.†

Why is your dose 500mg when the RDA is only 1.2mg?

The RDA (1.1-1.2mg) is the minimum to prevent classical deficiency — not the amount for optimal everyday support. Thiamine is water-soluble with no established upper limit; your body uses what it needs and excretes the rest. High-potency doses like 500mg are commonly used in both research and daily supplementation.†

Why not just take a B-complex?

Most B-complex supplements contain 1-5mg of thiamine — spread thin across 8+ vitamins. If you specifically want high-potency B1 support, a dedicated 500mg gummy delivers far more thiamine than a generic complex.†

When should I take these?

Take in the morning or early afternoon with or after food. B1 is water-soluble and non-stimulating, so it won't keep you up — but morning dosing helps many people feel the energy and clarity support throughout the day. Consistency matters most.†

Are there any side effects?

Vitamin B1 is generally very well tolerated, even at high doses. Because it's water-soluble, excess is excreted naturally through urine. There is no established toxic upper limit for thiamine. Rare reports include mild stomach discomfort if taken on an empty stomach. Consult your healthcare provider if you're pregnant, nursing, or taking medications.

How long until I notice a difference?

Many people incorporate B1 into a daily routine and assess how they feel over 1-4 weeks of consistent use. B1 works cumulatively — daily consistency is key. Individual experiences vary.†

Can I pair this with other KIND NATURE products?

Absolutely. Many customers pair our B1 gummies with our B2 Riboflavin for broad B-vitamin support, or with our Magnesium gummies for everyday energy and nervous system support. B1 and B2 both play roles in the body's energy metabolism. Consult your healthcare provider if taking prescription medications.†

Is this safe for kids and teens?

Our gummies are formulated for adults and children ages 4+ (with adult supervision). The strawberry flavor makes them easy even for picky eaters. Thiamine is water-soluble and well-tolerated across age groups. Always consult your pediatrician before starting any new supplement for children.

Is this safe for daily long-term use?

Yes. Thiamine is water-soluble, non-habit-forming, and has no established upper intake limit. At 500mg per serving you're well within the range used in research and daily supplementation. Your body simply excretes what it doesn't need.†

Is this vegan and clean?

Yes — 100% vegan, pectin-based (no gelatin), naturally strawberry-flavored. No artificial colors, no synthetic fillers, no proprietary blends. Third-party tested for purity and potency.

Build Your Daily Routine

B1 is one foundation. Pair with B2 Riboflavin and Magnesium for broad everyday energy and nervous system support — at clinical doses, with full transparency.†
