The Cellular Energy Vitamin Your Body Actually Needs.
Vitamin B2 (Riboflavin) is one of the most fundamental nutrients in human biology. Your body uses it for over 70 enzyme reactions, including the ones that power cellular energy production in your brain, your muscles, and your nervous system. Without enough B2, those reactions slow down — and the effects show up as fatigue, low mood, and reduced energy at the cellular level.†
Here's the catch: the 1.7mg of B2 in your multivitamin is the daily amount needed to prevent classical deficiency (like cracked lips or sore tongue). It is not the therapeutic dose used in clinical research. Studies examining B2's role in cellular energy metabolism, mitochondrial function, and neurological support use 200-400mg per day — 100-200x the multivitamin amount.†
The research is decades deep. The Schoenen 1998 study, published in Neurology, established 400mg/day as a meaningful dose in research on B2's role in cellular and neurological function — including research that has explored its use in migraine prevention contexts. The American Headache Society lists riboflavin in its evidence-based guidelines.†
It works by serving as a precursor to FAD and FMN — cofactors required by the electron transport chain that produces ATP, your cells' energy currency. When B2 is plentiful, those mitochondria run efficiently. When it's low, they don't.†
A gummy you'll actually take daily. The clinical research dose. For your everyday cellular energy, nervous system, and antioxidant support.†

ONE INGREDIENT. ONE PURPOSE. THE CLINICAL DOSE.
Why 400mg, and Why It Matters.
One ingredient. At the dose researchers actually use. That's the difference between a vitamin and a clinical protocol.†
Vitamin B2 (Riboflavin) — 400mg
The exact dose used in the Schoenen 1998 clinical study on B2's role in cellular and neurological function. Powers mitochondrial energy production in cells throughout the body — supporting healthy cellular energy metabolism.†
Why 400mg, Not 1.7mg
The 1.7mg in multivitamins is the daily requirement to prevent classical deficiency — not a therapeutic dose for cellular energy support. Clinical research uses 200-400mg. We use the research dose. Don't be fooled by underdosed alternatives.†
Antioxidant Support
Riboflavin is a precursor to FAD and FMN — cofactors required for the regeneration of glutathione, your body's master antioxidant. Supports normal cellular defense and energy metabolism throughout the body.†
Nervous System Foundation
B2 supports normal nervous system function, energy production, and red blood cell formation. It's water-soluble — your body doesn't store it, so daily intake matters. Excess is excreted (bright yellow urine is normal and harmless).†
Clean Gummy Format
Pectin-based (vegan, no gelatin). Naturally flavored. No artificial colors, no synthetic fillers, no proprietary blends. Just 400mg of pure Riboflavin in a gummy you'll actually remember to take.†
THE SCIENCE
The Research Behind 400mg Riboflavin.
B2 is one of the most clinically studied nutrients in human energy metabolism. Here's what the research shows — and why the dose matters more than the marketing.†
Schoenen 1998 — The Foundational Study
Published in Neurology. Established 400mg/day of Riboflavin as a meaningful dose in clinical research on B2's role in cellular energy metabolism and neurological function, including research that has explored its use in migraine prevention contexts.†
Mitochondrial Energy Production
Riboflavin is a precursor to FAD and FMN — cofactors in the electron transport chain that produces ATP, the cellular energy currency. B2 supports the foundational machinery of cellular energy in every cell of your body.†
Decades of Clinical Research
B2 is one of the most-studied B vitamins in human health, with published research spanning decades covering its roles in cellular energy metabolism, mitochondrial function, nervous system support, and antioxidant defense.†
Excellent Safety Profile
Water-soluble. No known toxicity at the doses used in published research. Excess excreted in urine (bright yellow — completely harmless and a sign B2 is being absorbed).†

WHY KINDNATURE B2
Most B2 gummies use 1.7-50mg of Riboflavin — the daily-deficiency-prevention amount. That's not the clinical research dose. Studies examining B2's role in cellular energy and nervous system support use 400mg. We use 400mg. Single ingredient, single purpose, full transparency. No proprietary blends hiding underdosed nutrients. If you've researched your way to B2, you're in the right place.†
WHAT OUR CUSTOMERS SAY
Trusted by people who actually read the labels.
My neurologist suggested adding B2 at 400mg to my daily routine - tried the horse pill capsules first and gave up after 2 weeks (couldn't get them down consistently). Found these gummies, same 400mg dose. Easier to actually take. About 3 months in and I'm in a way better place with my overall head wellness. The yellow urine thing was weird at first lol but it's just B2 doing its thing apparently.
Was swallowing the big yellow B2 horse-pills for years. These gummies are the same 400mg dose but actually pleasant to take. Bright yellow urine is the only sign you're getting the real dose - which means these AREN'T underdosed like other gummy brands with 25-50mg. Reorder set up.
Did a deep dive on B2 after reading some of the research. Most B2 supplements in gummy format are 25-50mg - which is barely above the multivitamin amount. Kindnature is one of the only brands actually using the 400mg dose. That's why I trust them. Plus the gummy is way better than the horse pill route.
I stack this with the 2-in-1 Magnesium and L-Theanine. Three months in feeling way better in my daily wellness. The transparency on dosing brought me to Kindnature originally - no proprietary blends, just real science. Bonus that the gummies taste good which matters when you're taking 2 a day.

Frequently Asked Questions
Why 400mg of B2 — isn't that a lot?
400mg is the dose used in the Schoenen 1998 clinical study published in Neurology — research that examined B2's role in cellular energy metabolism and neurological function. The 1.7mg in multivitamins is the basic daily requirement to prevent classical deficiency, not the dose used in research on cellular energy support.†
B2 is water-soluble, so excess is excreted in urine (which may turn bright yellow — completely harmless and actually a sign the B2 is being absorbed).†
How long before I notice a difference?
B2 typically requires 4-12 weeks of consistent daily use for the body to build up nutrient saturation and for cellular energy effects to compound. Clinical research on B2 typically measures outcomes at 3 months.†
Consistency matters more than dose. The best supplement is the one you actually take daily. Individual experiences vary — if you have ongoing health concerns, consult your healthcare provider.
Will my urine turn yellow?
Yes, very likely — and that's a good sign. Riboflavin is naturally bright yellow, and any excess your body doesn't immediately use is excreted in urine. The brighter the yellow, the better the absorption.
It's harmless, expected, and one of the easiest ways to confirm you're getting a real clinical dose (not the 1.7mg in a multivitamin).†
Can I take this with prescription medications?
B2 has an excellent safety profile and is generally well-tolerated alongside most medications. It's water-soluble with no known major interactions.†
That said, always consult your healthcare provider before starting any new supplement, especially if you're on multiple medications or have ongoing health conditions.
How does this compare to other B2 supplements?
Most B2 gummies contain 25-50mg of Riboflavin — barely above the daily-deficiency-prevention amount. Many use proprietary blends that hide underdosed nutrients.†
Kindnature's B2 gummies deliver the 400mg dose used in published clinical research on B2's role in cellular energy. Single ingredient, full transparency, no fillers.†
Should I stack this with Magnesium or L-Theanine?
Many of our customers do — B2, Magnesium, and L-Theanine each support different aspects of cellular and nervous system function, so they tend to complement rather than overlap.†
For starting out, B2 alone is the most evidence-backed foundation. From there, build up based on your individual routine and what your healthcare provider suggests.
Is this safe for kids?
The 400mg dose is studied in adults. For children, age-appropriate dosing is different. Consult your pediatrician before giving any new supplement to anyone under 18.
That said, B2 has an excellent safety profile — it's water-soluble with no known toxicity at the doses used in published research.†
When should I take them?
Take 2 gummies daily — ideally with food for best absorption. Morning is most common since B2 supports cellular energy production, but timing flexibility is yours.†
Consistency matters more than time of day. Set a daily anchor (with breakfast, with coffee, on your bedside table) and stick to it for the full 12 weeks.
Is this vegan and clean?
Yes — 100% vegan, pectin-based (no gelatin), naturally flavored. No artificial colors, no synthetic fillers, no proprietary blends. Third-party tested for purity and potency.
