THE TRUTH

Most supplements use marketing doses, not research doses.

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.†

Proprietary blends Hide individual doses behind a single total. You never know what you're actually getting.
Marketing-dose vitamins 50mg of B2 when research uses 400mg. 100mg of magnesium when research uses 400-600mg.
Wrong forms Magnesium oxide (poorly absorbed, ~4% bioavailability) instead of glycinate or citrate (well-absorbed, better tolerated).
Cellular energy is the foundation.

Cellular energy is the foundation.

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.†

THE SCIENCE

Three nutrients. Real doses.

Each one backed by clinical research on cellular energy, nervous system function, and women's hormonal balance.†

VITAMIN B2 (RIBOFLAVIN)
400mg
per daily serving
HOW IT WORKS
Riboflavin is a precursor to FAD and FMN — cofactors in the electron transport chain. Powers mitochondrial energy production in cells throughout the body — supporting healthy cellular energy metabolism.†
BEST FOR
Foundation of any cellular energy routine. The clinical-research dose, not the multivitamin dose.
Schoenen et al. (Neurology 1998): Established 400mg/day as a meaningful dose in published research on B2's role in cellular energy metabolism and neurological function.
MAGNESIUM
1400mg
glycinate + citrate (dual-form blend)
HOW IT WORKS
Up to 68% of Americans don't meet daily magnesium intake. Glycinate is the gentle, calming form. Citrate is one of the most-researched forms in clinical research on women's hormonal balance and nervous system support.†
BEST FOR
Daily mineral routine, restful sleep support, cycle support, anyone with low magnesium intake (most Americans).
Magnesium has decades of clinical research across multiple structure/function contexts including restful sleep, muscle function, and nervous system support.
L-THEANINE
200mg
per daily serving (top of research range)
HOW IT WORKS
L-Theanine promotes alpha brain wave activity — the relaxed-but-alert state. Supports calm focus during everyday stress.†
BEST FOR
Daily stress, calm focus, anyone in high-stress periods who wants alertness without sedation.
Multiple clinical trials show 100-200mg L-Theanine supports stress markers and relaxed alertness without sedation.†
Consistency is the routine.

Consistency is the routine.

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.†

WHICH IS RIGHT FOR YOU

Find your starting point.

Different routines call for different starting points. Choose what fits your life.†

Just starting your routine?

Begin with B2. The most clinically studied of the three for cellular energy metabolism — strongest research base and longest track record.†

RECOMMENDED

High-stress periods?

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.†

RECOMMENDED

Building cycle 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.†

RECOMMENDED

Building a comprehensive daily routine?

Run the full stack. Three nutrients hit different mechanisms — compounding effect is strongest when used consistently together as part of a daily routine.†

RECOMMENDED
WHAT TO EXPECT

B2 and Magnesium are a 3-month routine. L-Theanine acts faster.

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.†

WEEK 1-4

Building consistency

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.

WEEK 5-8

Levels stabilize

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.†

WEEK 9-12

Routine becomes habit

By 3 months, the daily routine should feel automatic. Clinical research on B2 and magnesium typically measures outcomes around this window.†

MONTH 4+

Long-term support

Continue daily. As with most nutrient-based routines, the cellular support continues with consistent intake. Make it a habit, not a phase.

QUESTIONS

Nervous System Stack FAQ

Real answers from the team — about doses, timing, interactions, and what to expect.†

Should I take all three together?

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.†

How long before I notice a difference?

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.†

Are these safe with prescription medications?

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.

Why 400mg of B2 — isn't that a lot?

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).

Why this magnesium blend specifically?

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.†

Can I take L-Theanine every day?

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.

Does cycle timing affect my routine?

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.†

What if I'm pregnant or breastfeeding?

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.

Are these vegan?

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.)

Can I take more than the recommended dose?

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.

Individual results may vary. Consult your healthcare provider before starting any new supplement, especially if you are pregnant, breastfeeding, on medication, or have a medical condition.
