What is SLP-1?

SLP-1 is a doctor-prescribed mint chewable tablet that helps you fall asleep. It contains ramelteon, the active ingredient in an FDA-approved sleep medication, plus magnesium glycinate and DHHB, chosen to complement it.

Instead of sedating the brain like most prescription sleeping pills, ramelteon targets the melatonin receptors that regulate your sleep-wake cycle. Magnesium glycinate is a well-absorbed form of magnesium, a mineral involved in muscle relaxation and nerve function. DHHB is a natural bioactive compound traditionally used as part of an evening wind-down.

SLP-1 is a compounded medication, and compounded medications aren’t FDA-approved.

Benefits

Falling asleep faster

SLP-1 is made to help you fall asleep faster, even when your mind won’t switch off. Drift off, don’t get knocked out.

Waking up like yourself

Sleep well, then wake up like yourself, with no next-day grogginess.

Better days

Sleep better, look and feel better. That can mean more patience for your day, and for the people in it.

Individual results may vary.

May cause drowsiness. Don’t drive or drink alcohol after taking.

Who should take SLP-1?

SLP-1 may be a good fit for adults with mild to moderate sleep issues, mainly trouble falling asleep. It’s often a good option for people who:

  • feel their mind switch on the moment their head hits the pillow
  • have tried the usual fixes without the results they want
  • want something that isn’t a heavy sleeping pill
  • feel tired but wired at night

‍

SLP-1 is not appropriate for everyone. You should not take it if you take fluvoxamine (Luvox), are pregnant or breastfeeding, have diabetes or liver or kidney disease or have had a serious allergic reaction to ramelteon. If you have sleep apnea, your doctor will review it first, since SLP-1 is not designed to treat this condition.

SLP-1 may be prescribed to eligible adults ages 18 to 75. A Willow doctor will review your health history and determine if treatment is right for you.

‍

Can I use SLP-1 with other treatments?

Possibly, and your doctor will check. During your online assessment, you’ll share your health history and any medications or supplements you take. Your Willow doctor reviews them for possible interactions before prescribing, and you can message them if anything changes after you start.

How do I take SLP-1?

Take 1 chewable tablet about 30 minutes before you plan to sleep, at about the same time each night. Chew it completely before swallowing, no water needed, and skip big or high-fat meals right beforehand since food can slow it down.

Ready for bed, but your brain isn't

You’re exhausted, but the moment your head hits the pillow, your mind switches on and bedtime turns into a battle.

The science behind SLP-1

Falling asleep starts with a signal from your body clock, a small area of the brain called the suprachiasmatic nucleus. Ramelteon, the active ingredient in SLP-1, binds to two melatonin receptors there, MT1 and MT2, and its effects last longer than melatonin’s.

Most prescription sleeping pills act on GABA-A, a receptor that quiets the brain broadly. Ramelteon has no meaningful effect on it. A traditional sleeping pill flips the breaker for the whole house. SLP-1 dims the lights in the one room that needs it, and it does its work at the start of the night.

Ramelteon has a track record. In a six-month study of 451 adults with chronic insomnia, it helped people fall asleep faster than placebo at every check-in. Those results are from studies of ramelteon on its own.

What to expect from SLP-1

Patients may notice:

Bedtime that doesn’t turn into a battle with their own brain

Drifting off instead of running through tomorrow’s to-do list

Less of that tired-but-wired feeling at night

No second thoughts about taking it again tomorrow night

A note from Dr. Green

As Willow’s Chief Medical Officer, I look closely at how treatments hold up in real life, beyond how they perform on paper.

If you want to look and feel your best, there’s no single way to get there. When a plan fits your body and your life, it can help you feel more confident and comfortable in your own skin. 

That’s why we build your treatment plan around you. You shouldn’t have to adjust to your care. Your care should adjust to you.
Individual results may vary.

How should I store SLP-1?

Store SLP-1 at room temperature, away from heat and moisture, and out of reach of children. Use it by the date on the label.

Like any prescription treatment, SLP-1 can cause side effects. The most common are drowsiness, dizziness, tiredness and nausea.
