The honest answers, before you commit.
Results, and how fast you feel them.
Does it actually work?
Yes. Every active is named, dosed, and traceable to published research.
If it does not work for you, you have 30 days from delivery to get your money back.
See the studies and dosesHow fast will I feel something?
Some of it the first day. The deeper part over weeks.
What is the gut-brain axis, in plain terms?
It is the two-way line between your gut and your brain.
When your gut is under-supported, your head often feels it. The protocol supports that connection from the gut side.
How the gut-brain axis worksHow is this different from what did not work for me?
Most of what you tried was one ingredient, in one bottle, at one time of day.
This is a named strain, L. plantarum DR7, paired with the Bimuno prebiotic that feeds it, and split across a morning and an evening formula so the gut-brain connection is worked at both ends of the day.
Is it safe, and what is in it.
Is it safe?
Yes. It is made for daily use.
Every active is a named, clinically studied ingredient. The Bimuno prebiotic is made from lactose and contains milk. If pregnant, nursing, or on medication, ask your healthcare provider first.
Are there stimulants?
None.
The morning supports calm focus with no caffeine and no crash. The evening winds you down without melatonin, so no morning grogginess.
What is in it?
A clinically studied probiotic and prebiotic in both formulas, plus a timed active in each.
Morning holds L-theanine 200 mg, an active B-complex, the DR7 strain, and Bimuno prebiotic. Evening holds magnesium bisglycinate 200 mg with the same gut-brain base.
See every dose and its studyWhat did you deliberately leave out?
Anything the evidence did not justify at a sensible dose.
No herbal sedatives, no melatonin, no caffeine, no megadoses. Each was a deliberate decision, and we will tell you why.
The honest limits of the evidenceCan I verify the batch I receive?
Yes. Batch lookup goes live when the first lots ship.
Finished-lot third-party testing is required before any lot is released. When your first order ships, the QR code on the carton will match the batch in your hand to its independent lab test.
Ten seconds, morning and night.
How do I take it?
One in the morning, one at night. No pills, no capsules.
Tear each into a glass of cool water and stir. About ten seconds, morning and night.
See the daily ritualHow do they taste?
Peach Mango to start the day. Hibiscus Vanilla to wind down.
Both are light powders made to mix clean into cool water, never syrupy or chalky.
Do I need both, or can I take just one?
Either works on its own, and they are designed to work best together.
Both carry the same gut-brain base, so the full protocol works the connection around the clock.
Can I take it with coffee?
Yes. The morning formula is caffeine-free, so it pairs with your coffee.
It adds calm focus without stacking another stimulant on the one you already had.
The practical questions, before you buy.
When does it ship, and how do I get it?
The first box ships Fall 2026.
Choose a founding subscription plan. You are charged today, your first box ships Fall 2026, and your plan renews at the price and cadence you chose until you cancel. Cancel before it ships for a full refund.
See the protocolHow will I be able to subscribe?
A subscription delivers your protocol on a schedule, so you never run out.
Choose monthly, 3-month, or 6-month, or buy once without a subscription. You see the recurring price, billing cadence, first-charge timing, and cancellation terms before checkout.
What if it does not work for me?
You are covered by a 30-day money-back guarantee.
If it is not right for you, contact us within 30 days of your first delivery for a full refund of that first order's product purchase price. The window starts when your first box arrives, not when you order.
How does shipping work?
Your protocol ships straight to your door.
Shipping is free on every U.S. order over $50, and every Serene Biotics protocol qualifies.
Founding subscriptions ship first from serenebiotics.com in Fall 2026. You can also order on Amazon when we ship.
How do I cancel, pause, or skip a delivery?
You are in control, and it takes one click.
Manage everything from your account: sign in, open Manage subscription, and skip a delivery, pause, switch between the morning and evening formulas, or cancel any time. No retention maze, no phone call. Prefer a hand? Email support@serenebiotics.com.
Go to your accountAny allergens?
One allergen to flag: milk.
Our Bimuno® GOS prebiotic is derived from lactose, so the protocol contains milk. It is gluten free, made with Non-GMO ingredients, caffeine-free in the morning, and melatonin-free at night.
How is it tested before it ships?
Every lot has to clear an outside lab before it ships.
The lab checks identity, potency, and contaminants. A Certificate of Analysis goes live for every lot at launch, and you will be able to look yours up by the code on your carton.
Our testing commitmentWhat if I am pregnant, nursing, or on medication?
Talk to your healthcare provider before you start.
That is the right call with any supplement, and we would rather you ask than guess. If you ever feel unwell, stop use and call us at (888) 594-8985.
What is in the founding welcome kit?
Included with the 3- and 6-month founding plans.
Founding members on a 3- or 6-month plan receive a welcome kit: an insulated water bottle, a vegan-leather travel pouch, and a Serene Biotics cap. The 6-month plan also adds a bonus month at no charge.
