Fall Asleep Faster. Stay Asleep Longer. Wake Restored.

When stress, travel, or late nights throw off your sleep, your body needs more than a quick fix — it needs a reset. Thorne’s Sleep Stack combines three targeted formulas to calm the mind, relax the body, and realign your natural sleep rhythm, so you can drift off easily and wake up truly refreshed.*

  • Magnesium Bisglycinate: Highly absorbable magnesium to relax muscles, ease tension, and support deeper, more restorative sleep.*

  • Melaton-3: 3 mg of melatonin to reset circadian rhythm and help you fall asleep faster — ideal for shift workers or travelers.*

  • PharmaGABA-250: A natural form of GABA that promotes calm brain activity, lowers stress biomarkers, and prepares the mind for restful sleep.*

Together, this trio promotes deep, restorative rest without grogginess, helping you recover, recharge, and perform at your best every day.*

The cleanest feeling and most restful sleep I've had.

I don't sleep like a baby with this package - up every two hours. . . I sleep like a teenage boy. I couldn't be happier.

This is legit. Definitely helps with sleep. The magnesium needs to be dissolved in water but I think the taste is pretty good. The other two are pills.

I developed restless arms in my 3rd trimester of pregnancy. 2 years later and I still have them. This regimen is the first of MANY things I've tried to get rid of them and it works. Have not had that horrible nighttime feeling since my first night of taking this bundle. I am forever grateful

This bundle is fantastic. I've used this on and off to help adjust to a new work schedule, and I've been sleeping better even on days I do not use the full group.

I have had great results with these products and as a picky eater was pleasantly pleased with the taste of the powder.

Melaton-3 gave me an extra ~hour of deep sleep. I just got right out of bed almost right away, and it was a strange, new experience.

Frequently Asked Questions

Most single sleep aids address only one part of the problem. The Sleep Stack supports every layer of healthy sleep: magnesium relaxes muscles, melatonin resets circadian rhythm, and PharmaGABA calms brain activity. Together, they deliver deeper, more restorative rest than any one supplement alone.*

  • Magnesium Bisglycinate: Mix one scoop with at least eight ounces of water daily.
  • Melaton-3: Take one capsule at least 30-minutes before bedtime.
  • PharmaGABA-250: Take one capsule one to three times daily.

Yes. The formulas are gentle, non-habit forming, and safe for daily use. Consistency supports healthier sleep patterns over time.*

Many people feel calmer and fall asleep more easily the first night. With regular use, the stack helps improve sleep quality and circadian rhythm balance over days to weeks.*

The Sleep Stack is generally safe alongside most supplements. However, if you take prescription medications (especially sleep aids, sedatives, or antidepressants), consult your healthcare provider before use.

Because quality sleep is the foundation of energy, focus, and recovery. The Sleep Stack combines magnesium to relax muscles, melatonin to reset your circadian rhythm, and PharmaGABA to calm the mind. Together, they help you fall asleep faster, sleep deeper, and wake feeling refreshed — benefits that a single sleep aid often can’t deliver.*

Allergy Warning: Contraindicated in individuals with a history of hypersensitivity to any of the ingredients.

Pregnancy & Nursing: If pregnant, nursing, or trying to conceive, consult your healthcare practitioner before use. Do not use Melaton-3 if pregnant or nursing.

Interactions:

  • Melaton-3 may potentiate the effects of blood-thinning medications and should be used with caution or avoided in individuals on anticoagulant therapy or prior to surgery.
  • Magnesium Bisglycinate and PharmaGABA-250 have no known adverse interactions at the time of publication.

Other Warnings: Magnesium may cause temporary gas, bloating, or diarrhea in some individuals. This typically resolves by reducing the dose.
