Cautions
Reishi Relax contains valerian root and passionflower, which can make some people drowsy. Don't drive or operate machinery until you know how it affects you, and don't combine with alcohol, sedatives or sleep medication. If you take prescription medication (especially blood thinners, immunosuppressants, antibiotics, thyroid or osteoporosis medication), check with your doctor or pharmacist first. Ask your doctor before use if you're pregnant or nursing, under 18, or have a kidney, liver or other medical condition. Keep out of reach of children.

The 10 PM problem

Your body clocked out.
Your brain didn't.

The lights are off and you're tired, but your mind is replaying the day and drafting tomorrow's to-do list. Most sleep products only work one side of that. The Sleep Core gives each side its own step.*

The mind side

The replay. The what-ifs. The 10 PM to-do list.

A busy mind is often what stands between a tired body and sleep. Reishi has been part of evening rituals in East Asia for centuries, and we paired it with L-theanine, lemon balm, passionflower and valerian root.

Step 1: Reishi Relax supports a calm, quieter mind as you wind down.*

The body side

Tight shoulders. Restless legs. A day still in your muscles.

Magnesium is a mineral your muscles and nervous system use every day, and nearly half of Americans get less than they need from food.1 Glycinate is a gentle, chelated form that's easy on the stomach.

Step 2: Magnesium Glycinate supports muscle relaxation and restful sleep.*

The ritual

Two steps. One night. No melatonin.

Same steps, same time, every night. That consistency is the point: a clear signal to your body and mind that the day is done.*

Step 1 · Quiet the mind9:30 PM

Chew 1 Reishi Relax gummy as you start winding down. Dim the lights, put the phone away.

Step 2 · Settle the body10:00 PM

Take 3 Magnesium Glycinate capsules with a glass of water, about an hour before bed.

Every nightLights out

Repeat it nightly. Give the routine two to four weeks before you judge it.

The Sleep Core isn't a sleeping pill or a sedative, and it won't knock you out. These are steady, fully disclosed amounts meant for a nightly routine, and we won't claim the science says more than it does.

What's inside

Six ingredients. Every milligram shown.

Step 1 · Reishi RelaxPer gummy
Reishi mushroom extract200 mg

Ganoderma lucidum, the "lingzhi" of traditional East Asian practice.

L-theanine25 mg

An amino acid found naturally in tea leaves.

Lemon balm25 mg

A lemon-scented herb in the mint family, long brewed as an evening tea.

Passionflower25 mg

A flowering vine traditionally taken as a calming tea.

Valerian root25 mg

A root used in European herbal tradition as an evening herb.

Step 2 · Magnesium GlycinatePer 3 capsules
Elemental magnesium275 mg

65% of the Daily Value, from 2,500 mg of magnesium glycinate: magnesium bound to the amino acid glycine.

Why glycinateChelated

A gentle form that's easy on the stomach. Cheaper magnesium oxide is poorly absorbed, around 4% in one study.2

The research4 weeks

In a 2025 trial of 155 adults with poor sleep, 250 mg of magnesium as bisglycinate gave a modest improvement in sleep quality versus placebo.3

48%of Americans get less magnesium from food than they need.1

Questions

Good to know

Still deciding? Email support@fivacore.com and we'll help.

Why two products instead of one?

Because a restless night usually has two sides: a busy mind and a body that hasn't let go of the day. Reishi Relax is the botanical step for your mind and Magnesium Glycinate is the mineral step for your body. Keeping them separate means every dose stays fully disclosed, so you can see exactly what you're taking.*

How do I take the Sleep Core?

Chew 1 Reishi Relax gummy as you start winding down, then take 3 Magnesium Glycinate capsules with water about an hour before bed. Some nights you may want a second gummy, but don't take more than 2 gummies a day.

How long does one Sleep Core last?

About 30 nights: 90 magnesium capsules at 3 a night and 30 gummies at 1 a night. If you take 2 gummies a night, the gummies last 15 nights.

Will it make me groggy?

There's no melatonin in either formula, and neither is a sleeping pill or a sedative. Valerian root and passionflower can make some people drowsy, so take the gummy in the evening and don't drive or operate machinery until you know how it affects you.

Can I take it with medication or alcohol?

Don't combine the Sleep Core with alcohol, sedatives or sleep medication. If you take prescription medication, especially blood thinners, immunosuppressants, antibiotics, thyroid or osteoporosis medication, check with your doctor or pharmacist first. If you're pregnant, nursing, under 18, or have a kidney, liver or other medical condition, ask your doctor before use.

How soon will I notice a difference?

Everyone is different. Routines work through repetition, so give the Sleep Core two to four weeks of nightly use before you decide. In the 2025 magnesium trial, differences were measured over four weeks.

Do both bottles ship together?

Both ship free from our US fulfillment partner and typically arrive in 5–7 business days. They may arrive in separate packages, and you'll get tracking by email as soon as your order ships.

What if it doesn't work for me?

You're covered by our 30-night money-back guarantee. Contact us within 30 days of delivery and we'll refund your Sleep Core, even if both bottles are open. You don't need to send anything back.

Where is it made?

Both formulas are made in the USA with globally sourced ingredients, in cGMP-compliant facilities, and ship from our US fulfillment partner.
