Vitamin B2 (Riboflavin) 400mg Gummies - Lemon Flavor
The dose that matters. 400mg of pure Riboflavin — the exact amount studied by researchers in cellular energy and mitochondrial function research. Not the 1.7mg in multivitamins.†
Three clinically-studied ingredients at the doses researchers actually use. For people who do their own reading on cellular energy, mitochondrial function, and nervous system wellness.†
Three primary nutrients with clinical research behind them. Plus L-Theanine for daily stress and calm focus.†
The dose that matters. 400mg of pure Riboflavin — the exact amount studied by researchers in cellular energy and mitochondrial function research. Not the 1.7mg in multivitamins.†
Glycinate + Citrate dual-form blend. Excellent absorption, gentle on the gut. Up to 68% of Americans don't meet daily magnesium intake.†
Supports the relaxed-but-alert state. Promotes alpha brain wave activity. Calm focus without sedation.†
Gold-standard mitochondrial antioxidant dose. Supports cellular defense via a different pathway than B2.†
Your cells run on cellular energy. Your nervous system needs the right minerals. The right nutrient stack — at clinical research doses — supports the foundations of how your body functions every day.†
Walk into any pharmacy or browse Amazon. Most "nervous system" or "brain support" supplements use proprietary blends that hide their underdosing — splashing in 50mg of B2 when the research used 400mg.†
For nutrients to support what they're studied to support, they have to be present in the exact doses shown in clinical research.†
Every cell in your body — including in your brain — runs on ATP, produced by mitochondria. B2 is a precursor to FAD and FMN, two essential cofactors in mitochondrial energy production. Real dose, real foundation.†
Each one backed by clinical research on cellular energy, nervous system function, and women's hormonal balance.†
Cellular nutrient saturation takes weeks, not days. Clinical research on B2 and magnesium typically measures outcomes at 90 days of consistent daily use. The supplement that supports your body is the one you actually take daily.†
Different routines call for different starting points. Choose what fits your life.†
Begin with B2. The most clinically studied of the three for cellular energy metabolism — strongest research base and longest track record.†
Add L-Theanine to your foundation. Supports relaxed-but-alert focus and the body's calm response. Stack with B2 and Magnesium for broader daily support.†
Magnesium is researched in women's monthly hormonal balance contexts. Estrogen fluctuations can affect mineral levels. Stack with B2 for compounding cellular energy support.†
Run the full stack. Three nutrients hit different mechanisms — compounding effect is strongest when used consistently together as part of a daily routine.†
Clinical research on B2 and magnesium typically measures outcomes at 90 days. L-Theanine can have noticeable calming effects within 30-60 minutes. Consistency matters more than dose.†
Start your daily routine. The loading phase — your body is incorporating these nutrients into its daily processes. L-Theanine may already support calm focus during stressful moments.
Your body is reaching steady nutrient levels. Some people observe shifts in how they feel during this window. Stay consistent — the compounding is happening at the cellular level.†
By 3 months, the daily routine should feel automatic. Clinical research on B2 and magnesium typically measures outcomes around this window.†
Continue daily. As with most nutrient-based routines, the cellular support continues with consistent intake. Make it a habit, not a phase.

Real answers from the team — about doses, timing, interactions, and what to expect.†
Many of our customers do. There are no known interactions between B2, Magnesium, and L-Theanine. Take B2 and Magnesium with food for best absorption; L-Theanine can be taken anytime — even before bed.†
B2 and Magnesium typically require 4-12 weeks of consistent daily use — clinical research typically measures outcomes around 90 days. The body needs time to build up nutrient saturation.†
L-Theanine can have more immediate calming effects (within 30-60 minutes of taking it), so you may notice that one faster — especially during stressful moments.†
Always consult your healthcare provider, especially if you're on prescription medications. While B2, Magnesium, and L-Theanine are generally well-tolerated, your doctor knows your full picture.
Magnesium specifically can interact with certain antibiotics, blood pressure medications, and bisphosphonates — so timing matters. Most providers recommend taking these 2 hours apart from such medications.
400mg is the dose used in the Schoenen 1998 clinical trial published in Neurology — research on B2's role in cellular energy metabolism and neurological function, including in migraine prevention contexts. The 1.7mg in multivitamins is the basic daily requirement to prevent deficiency, not the dose used in clinical research on cellular energy support.†
B2 is water-soluble, so excess is excreted in urine (which may turn bright yellow — completely harmless and a sign the B2 is being absorbed).
Our 2-in-1 Magnesium delivers 1400mg of dual-form magnesium: 400mg Glycinate for gentle, calming bioavailability, plus 1000mg Citrate — one of the most-researched forms of magnesium, including in landmark research on women's hormonal balance and migraine prevention contexts.†
Magnesium oxide (in cheap supplements) has only ~4% absorption — we don't use it. Glycinate is gentle on the gut and doesn't cause the digestive side effects common with cheaper forms.†
Yes. Unlike many calming compounds, L-Theanine doesn't build tolerance, cause dependence, or sedate you. It's the same amino acid you'd get from drinking green tea — just at a higher, more effective dose.†
Many of our customers take it daily, others use it just on high-stress days. Both approaches work.
Magnesium is researched in women's monthly hormonal balance contexts. Estrogen fluctuations during the menstrual cycle can affect mineral levels.†
For best results: take magnesium daily (not just during your cycle), and stack with B2 for the compounding effect. Some find starting L-Theanine 3-5 days before menstruation helps with the daily stress component too.†
Consult your healthcare provider before starting any new supplement during pregnancy or breastfeeding. Magnesium is often used in pregnancy under physician guidance, but every case is different.
B2 at 400mg is generally considered well above pregnancy requirements — your OB can advise whether it's appropriate for you.
Yes — these three are 100% vegan. Pectin-based (not gelatin), no animal-derived ingredients, no artificial colors. Plant-based and clean.
(Note: the only non-vegan product in our range is our Manuka Honey gummies, which are vegetarian.)
The doses on each label are based on what's been studied in clinical research — taking more doesn't add benefit and can cause side effects (especially with Magnesium, where high doses can cause loose stools).
If you feel you need broader support, stack the products (B2 + Magnesium + L-Theanine) rather than doubling up on one. Different mechanisms compound; same mechanism just causes side effects.
