The Cellular Energy Vitamin Your Body Actually Needs.
Riboflavin is an essential B vitamin that supports normal energy metabolism and normal nervous system function.†
Each labeled serving provides 400mg of vitamin B2 as riboflavin in a lemon-flavored gummy format. The amount is clearly disclosed with no proprietary blend.
Review the product label for complete ingredients, suggested use and cautions. Take only the labeled serving unless a qualified healthcare professional advises otherwise.

ONE INGREDIENT. CLEARLY LABELED.
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
Each labeled serving provides 400mg of riboflavin, with the amount clearly disclosed.†
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
Riboflavin is an essential B vitamin involved in normal energy metabolism and normal nervous system function.†
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).†

WHAT OUR CUSTOMERS SAY
Trusted by people who actually read the labels.
I wanted a clearly labeled 400mg riboflavin product without large capsules. The lemon gummy format is easy to add to my daily routine.
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?
Riboflavin is naturally bright yellow, and urine color may become brighter after use. This is an expected characteristic of riboflavin. If you have questions or ongoing health concerns, consult a qualified healthcare professional.
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?
Kindnature B2 gummies provide 400mg of riboflavin per labeled serving in a lemon-flavored vegan gummy. The amount is fully disclosed with no proprietary blend.†
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.
