Magnolia Bark is known for its anti-anxiety and stress-relieving effects, reducing depression, and promoting restful sleep.

Magnolia Bark (Magnolia officinalis, Magnoliae cortex, Houpo, Chua houpu) has been traditionally used in Chinese and Japanese medicine for the treatment of depression, anxiety, neurosis, and related neurological disorders.

Clinical research in the last couple of decades demonstrate how Magnolia Bark as a nootropic supplement can be so effective for taking care of what our ancestors already knew. By reducing anxiety, depression, pain, symptoms of epilepsy, and other neurocognitive disorders including Alzheimer’s.

The polyphenols found in Magnolia Bark include magnolol and honokiol which provide its nootropic benefits.

As a nootropic, Magnolia Bark is used primarily to lower stress and promote a good night’s sleep.

Magnolia Bark helps:

  • The Magnolia Bark compound honokiol appears to be as effective as diazepam for relieving anxiety with fewer side effects.
  • Magnolia Bark interacts with the adenosine A1 receptor, dopamine transporter, dopamine D5 receptor (antagonist), serotonin receptors 5-HT1B and 5-HT6 (antagonist), GABAA receptors, hippocampus acetylcholine release, and modulates serotonin activity.[i] And is an acetylcholinesterase (AChE) inhibitor.[ii]
  • The compounds honokiol and magnolol found in Magnolia Bark have been shown to significantly decrease β-amyloid (Aβ)-induced neuronal death associated with Alzheimer’s Disease.[iii]


Magnolia Bark (Magnolia officinalis) comes from the Magnolia tree originally found in Southeast Asia, Eastern North America, Central America and the Himalayas. Its flowers are fragrant with white petals.[iv]

Magnolia officinalis

Magnolia Bark was first recorded in the “Shennong Herbal Classic” from the Qin and Han Dynasty around 221 B.C. to 220 A.D. It was used to anxiety, asthma, depression, gastrointestinal disorders, headache, and more.[v]

More than 250 different chemical compounds have been identified in the flowers, bark, and leaves of the Magnolia. But most of its therapeutic potential comes from the bark and roots.

The Magnolia bud is almost exclusively used to treat sinus congestion and sinus headache.[vi]

Magnolia Bark is harvested in the spring from April to June. The root and branch bark are boiled in water and set aside until it turns a purplish brown color. This concoction is then steamed, rolled and dried.

Early chemical studies identified two main active ingredients in the Magnolia Bark: magnolol and honokiol. These neolignanes are the main active components providing its nootropic benefit. [vii]

Other bioactive compounds from Magnolia Bark are the alkaloids benzyl-tetrahydroisoquinoline and aporphine which are found in the leaves, branches and bark. These alkaloids may also have antispasmodic and muscle relaxant benefits.[viii]

Magnolia Bark has been traditionally used to treat diabetes, atherosclerosis, Alzheimer’s disease, gastrointestinal disorders, asthma, and microbial infections.

Studies in human cells indicate a growth inhibitor effect of honokiol and magnolol on human melanoma and carcinoma cells. There is increased interest in developing a novel analogue for chemotherapy derived from Magnolia Bark.[ix]

magnolia bark extractHow does Magnolia Bark work in the brain?

Magnolia Bark boosts brain health and function in several ways. But two in particular stand out.

  1. Magnolia Bark is anti-anxiety. Magnolia Bark is known for its anti-anxiety benefits as an alternative to benzodiazepines.[x]

 Honokiol found in Magnolia Bark has been shown to act on the GABAA receptor subunit α-2 which provides some of its anti-anxiety benefits.[xi]

  1. Magnolia Bark as an antidepressant. Main-stream psychiatric medicine often treats depression using SSRI’s. Which affects serotonin reuptake in the brain. 

Traditional Chinese medicine uses Magnolia Bark to treat depression instead. Studies have demonstrated the honokiol and magnolol found in Magnolia Bark help prevent decreases in serotonin in the frontal cortex, hippocampus, striatum, hypothalamus, and nucleus accumbens.

The combination of honokiol and magnolol also normalize hypothalamic-pituitary-adrenal (HPA) hyperactivity. And induce reductions in platelet activity by upregulating the cAMP pathway.

The results of these studies show how Magnolia Bark provides its potent anti-depressant benefits.[xii]

There is also growing evidence that inflammation in the brain contributes to depression. Here again, Magnolia Bark has been shown to significantly reduce levels of pro-inflammatory cytokines; tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), and interferon γ (IFN-γ).

Reducing inflammation in the brain may affect tryptophan metabolism which increases serotonin. Providing another way Magnolia Bark as a naturally effective option for dealing with depression.[xiii]

How things go bad

Chronic stress, anxiety, poor blood flow and free radicals (oxidative stress) can damage your brain. And one of the ways this manifests is memory loss.

It comes as no surprise that people with memory loss experience higher rates of anxiety and depression.

↓ Chronic stress reduces memory capacity

↑ inflammation kills brain cells

↓ Free radicals destroy neurons and synapses

↓ Acetylcholine (ACh) levels decline

Learning and memory decline

Magnolia Bark helps reduce inflammation, restores acetylcholine levels, and supports memory.

Magnolia Bark benefits

magnolia bark sleepMagnolia Bark taken as a nootropic supplement easily crosses the blood-brain barrier helping reduce oxidative stress in the brain and throughout the body.

Magnolia Bark is widely used to elevate mood, decrease pain, and improve immune health.

Magnolia Bark activates cannabinoid receptors in your brain. Cannabinoid receptors include CB1 and CB2.

CB1 receptor activation regulates memory, cognition, and motor control. Relieving pain, vomiting, reducing hyperexcitability in epilepsy, stimulating appetite, and euphoria.

CB2 receptor activation provides pain relief and reduces inflammation.[xiv] 

Magnolia Bark helps reduce stress by suppressing adrenaline and maintaining healthy cortisol levels.

Studies have shown that honokiol works as effectively as the anti-anxiety drug Valium® (diazepam) without the associated side effects.[xv]

And Magnolia Bark extract helps prevent memory loss because of its anti-inflammatory effects in your brain.

How does Magnolia Bark feel?

Neurohackers report that supplementing with Magnolia Bark provides an anti-anxiety effect within minutes of taking it. Some users say it works as well as diazepine.

Most say they feel relaxed and ready to sleep after taking Magnolia Bark. Using it as a sleep supplement helps them fall asleep faster and stay asleep throughout the night.

But dosage is important. And many users say you will not get the benefits of Magnolia Bark if you don’t follow dosage recommendations.

Feelings of anxiety and depression can be reduced significantly with Magnolia Bark daily supplementation.

Most report that Magnolia Bark is a great way to quickly reduce stress.

Magnolia bark dosageMagnolia Bark Clinical Research

Most of the clinical research for Magnolia Bark are animal studies with very few conducted with humans.

Magnolia Bark is anti-anxiety

Magnolia Bark has long been used as an anxiolytic. Most users report a reduction in anxiety when using it as a supplement.

A 2013 review by researchers at Emory University in Atlanta found that the compound honokiol in Magnolia Bark interacts with the GABAA receptor. The same receptor targeted by anti-anxiety drugs like diazepam and without the side effects caused by benzodiazepines.[xvi]

Another study at the University of South Carolina School of Medicine reported that magnolol and honokiol enhanced both pre-synaptic and post-synaptic GABA transmission in hippocampus neurons.

Magnolia Bark modulated all sub-receptors in this group regardless of the α, β, or γ subunit subtype. Suggesting that supplements containing magnolol and/or honokiol would be effective anxiolytics, sedatives and anti-convulsants.

But the researchers also noted side-effects and significant risk of drug interactions could also be expected.[xvii]

Magnolia Bark for sleep

User reviews of Magnolia Bark extract supplements often report using it for sleep.

Studies show Magnolia Bark holds promise for those who have trouble falling and staying asleep.

The compound honokiol significantly shortened the time to fall asleep to non-rapid eye movement (non-REM, NREM) sleep and increased the amount of non-REM sleep in animal studies.

Honokiol increased the number of state transitions from wakefulness to non-REM sleep, and from non-REM sleep to wakefulness.

But honokiol has no effect on either the amount of REM sleep or depth of sleep.

The study concluded that “honokiol promoted NREM sleep by modulating the benzodiazepine site of the GABAA receptor, suggesting potential applications in the treatment of insomnia, especially for patients who experience difficulty in falling and staying asleep.”

Clearly, those who use Magnolia Bark extract for insomnia have the clinical evidence to back up their claims.[xviii]

Magnolia Bark may prevent seizures

A study was conducted in Belgium with the aim of discovering natural compounds that could be further tested for the treatment of epilepsy.

The researchers collected 14 herbs used in Traditional Chinese Medicine used to treat epilepsy. Of six extracts that tested positive in an animal model for epilepsy, only Magnolia Bark extract showed antiseizure activity.[xix]

Honokiol has been shown to inhibit repetitive firing by blocking glutamate, NMDA and K+ evoked cationic influx. Both honokiol and magnolol were found to increase seizure thresholds but honokiol appeared to be more potent in animal studies.[xx]

Magnolia bark benefitsMagnolia Bark recommended dosage

Manufacturers of Magnolia Bark extract generally recommend a nootropic dosage of up to 500 mg per day. Effective dosage depends on the strength of the extract.

We do not have access to clinical data stating the maximum recommended daily dosage for Magnolia Bark.

But do NOT exceed the recommended dosage because studies show in excess, Magnolia Bark can be toxic and cause neuronal cell death.[xxi]

Magnolia Bark is fat-soluble and can easily cross the blood-brain barrier.

Because it is fat-soluble, Magnolia Bark must be taken with a healthy fat like unrefined coconut oil or other healthy oil to ensure absorption.

Magnolia Bark side effects

Magnolia Bark is non-toxic and safe for use as a nootropic supplement based on years of recent food safety studies.[xxii]

Magnolia bark cortisolHowever, although rare, side effects can include tremors, dizziness, excessive sleepiness, and muscle weakness.

Do NOT use Magnolia Bark if you are on blood-thinning meds. And discontinue its use at least two weeks prior to surgery.

Avoid using Magnolia Bark if you are pregnant or breastfeeding. One animal study documented honokiol and magnolol blocked calcium-dependent uterine contractions in rats.[xxiii]

Magnolia Bark should NOT be used if you are taking benzodiazepines because studies show this powerful herb significantly increases the sensitivity of GABAA benzo receptors.[xxiv] Combining the drug with Magnolia Bark may result in a benzodiazepine overdose.

Magnolia Bark extract can cause sleepiness, vertigo, and dizziness if you are using muscle relaxants.

Magnolol in Magnolia Bark will stimulate corticosterone secretion which will likely cause problems if you are using steroid medication.

We have reports spanning the last few decades of women developing kidney failure resulting in dialysis after using a Magnolia Bark supplement as part of a weight loss program.

Further investigation showed different alkaloid profiles from those expected from Magnolia Bark. Which likely means something other than pure Magnolia Bark extract was used.[xxv] The lesson here is make sure you are buying a genuine and pure Magnolia Bark supplement.

Type of Magnolia Bark to buy

Magnolia Bark extract is available in capsules, tablets, bags of powder, loose bark tea, and liquid extract.

Magnolia Bark extract is offered in various strengths. Including a certain percentage of honokiol and magnolol which are the two active compounds found in this herb.

Relora® is a proprietary and patented blend of Magnolia Bark extract and Phellondendron amurense bark extract made by Lonza. And licensed for use by dietary supplement manufacturers.

Relora® is supported by 3 peer-reviewed, randomized, double-blind, placebo-controlled studies demonstrating a 42% improvement in mood states, 18% increase in vigor, 11% overall reduction in stress, and a 20% reduction in depression.[xxvi]

Do your best to choose a Magnolia Bark extract supplement made in a GMP facility with no “other ingredients” other than the capsule. And a testing program in place ensuring quality and purity.

My recommendation for a Magnolia Bark extract supplement is: Thorne Research – Relora Plus.

Nootropics Expert Recommendation

Nootropics Expert Tested and ApprovedMagnolia Bark extract up to 500 mg per day.

I recommend using Magnolia Bark extract as a nootropic supplement.

Your body does not make the compounds honokiol and magnolol found in Magnolia Bark on its own. So, to get its benefits you must take it as a supplement.

Magnolia Bark is especially helpful for those dealing with anxiety and stress. Studies show and users report it as effective for taming anxiety as benzodiazepines. But without the side effects associated with these drugs.

Magnolia Bark is reported to work well for those suffering from insomnia. Taken as a sleep aid, Magnolia Bark extract helps you fall asleep faster, and stay asleep.

Magnolia Bark extract is also helpful for those suffering from Alzheimer’s. It acts as an acetylcholinesterase inhibitor which increases acetylcholine levels often lacking in the Alzheimer’s brain.

This nootropic herb helps relieve symptoms of depression by maintaining healthy serotonin levels. And reducing the pro-inflammatory cytokines often found elevated in those with depression.

Keep in mind that Magnolia Bark is fat-soluble and requires healthy fats from a meal, or a tablespoon of unrefined coconut oil or MCT Oil for absorption.

Look for purity and quality in a supplement. And for Magnolia Bark a good choice if you are new to this nootropic supplement is: Thorne Research – Relora Plus.

Hi I purchased Honopure. My question is can I take honokial with my full spectrum CBD THC tincture?

    David Tomen
    February 1, 2023

    Michele, shouldn’t be a problem. They work on two completely different systems.

Chaim Bochner

Hi. Taking low dos 7.5 Remeron. Is there a problem with Magnolia?

    David Tomen
    January 10, 2023

    Chaim, theoretically there should not be a problem. Nothing has been published that shows any contraindication. But Magnolia Bark is a strong supplement so I suggest using caution. And double check this with your doctor as well.

October 16, 2022

Hi David,

I am interested in Magnolia Bark. Not for sleep as I feel like I sleep well, the CBD isolate and tryptophan plus some sleepy time tea really helps that.

I am interested in it for the anxiety aspect. I also have some higher cortisol in the mornings, which can cause some anxiety in the mornings. Would taking it at night help with morning cortisol levels? I don’t want to take it during the day as I really dislike being drowsy all day.

Also, would it be ok to take it since I am taking Lithium Orotate? Any interaction there?
Would it be ok to still take it with the CBD, and tryptophan as well?

    David Tomen
    October 22, 2022

    Susan, the only one of that may be a problem with Magnolia Bark is L-Tryptophan. But there have been on reported contraindications so you’d just have to try it.

    The best way to control cortisol in the morning is with 100 mg L-Theanine and 100 mg Phosphatidylserine (PS).

September 24, 2022

Hello, David, I apologize in advance for the length but I’ll try to be as brief as possible. I am a 72 year old woman with 41 years of depression. I’ve been on at least 15 medications and had transcranial magnetic stimulation with a little improvement. However, my biggest problem is a lack of motivation that prevents me from doing nothing more than barely taking care of myself. My husband does most everything that gets done. I am on Pristiq for depression, Trazadone for sleep. I take some supplements: lion’s mane, ashwaganda, l-tyrosine, lots of B1, and other things. When I first developed depression I was put on Limbritrol which gave me all kinds of motivation. It was an extreme and I wouldn’t want it any more. But since it was a benzodiazapine and I’ve heard magnolia bark is similar to a benzodiazepine, I was wondering if it might help me. I bought a bottle but wanted to make sure it’s safe before I take it. I also have inattentive type ADD and used to take Adderall for it but doctors don’t want me to take that any more due to my age. Since my mother and her mother had dementia and I have one APOE variant, I fear dementia with the mental decline I do feel. Every year the doctor gives me that annoying test you spoke of, with the clock drawing and 3 word recall and I always pass. I don’t know exactly what to do about memory problems etc. As I mentioned above I do use tyrosine and it helps a little. My problem is having sleep apnea and narcolepsy, I average sleeping 12 hours a day. If I take it 3 times a day how should I divide it? I’m not usually up in the early morning although I try to work toward it. (The bottle says 1/8 tsp. is 350mg.) I’d appreciate any help you can give me. I feel like I’m forgetting something but maybe I’ll think of it later.

    David Tomen
    September 26, 2022

    Linda, manufacturers typically recommend 500 mg Magnolia Bark per day. So, you really should ask the dosage recommended by the manufacturer of the supplement you have. They have far more experience when it comes to dosage and their product.

      September 28, 2022

      Thank you so much. I forgot to mention my meds for hair loss. They are clabetasol for my scalp 3 times a week and fluocinolone acetonide topical oil once a week. As I said before I take pristiq for depression and Trazadone for sleep plus supplements mentioned previously. So it’s safe to take magnolia bark with them? My magnolia bark capsules have 400 mg. Thanks so much. Mainly concerned for safety. I appreciate all you do.

        David Tomen
        September 29, 2022

        Linda, Pristiq is a serotonin-norepinephrine reuptake inhibitor (SNRI). And Trazadone affects serotonin and its receptors. Magnolia Bark is likely highly contraindicated while using those drugs. Not a good idea.

        September 29, 2022

        Hopefully the NALT is ok. Can I add the artichoke extract safely or not?
        Thanks again.

        David Tomen
        October 1, 2022

        NALT could cause problems. But Artichoke Extract should not be a problem.

April 28, 2022

first question, Magnolia Bark does it increase GABA receptor sensitivity or will it like a benzo after a long time cause issues with the Gaba receptors I want to up it to 300mg but worried my body will get used to higher amounts

second question I cannot find any mag bark without other toxic stuff like silicon dix and Mag stearate and its in my melatonin also, how much can my body handle of these stupid binding agents?

Third question, is 1MG melatonin long term safe been on it for a month or should I gave it a break?

    David Tomen
    April 28, 2022

    Andrew, none of the clinical studies show Magnolia Bark causing a problem with receptors like you get by using benzos. It should not desensitize receptors.

    You can find supplements without toxic additives but you really have to search for them. This one for example is pure: (Amazon). You should be able to find a melatonin supplement without “other ingredients” as well.

    1 mg of melatonin should not be a problem long-term either. That dosage is just slightly more than what your brain naturally produces at night.

February 22, 2022

Can Relora be taken with SSRI ?

    David Tomen
    February 22, 2022

    Robert, as far as I can tell SSRIs should not be a problem. But you must stay away from benzodiazepines when using Magnolia Bark.

February 13, 2022

Hi David, Is this brand a good choice for Magnolia Bark?

Bulk Supplements Magnolia Extract Powder

    David Tomen
    February 14, 2022

    Joe, Bulk Supplements is a good company because they test their products and what it says on the label is what is in the bag or capsule. The only problem with this Magnolia Bark extract is you don’t know what percentage of honokiol and magnolol is in this powder. Better to get a Magnolia Bark extract supplement where they tell you exactly what percentage of honokiol and magnolol is in their product.

February 13, 2022

Should I stop using Magnolia Bark if I catch Covid or get a Covid VAX booster or avoid anything else like L-theanine, Sorry for the barrage of questions lately? Just want to make sure its fine taking these if one gets sick


    David Tomen
    February 14, 2022

    Andrew, if you get COVID-19 or want to avoid it getting any worse you need Quercetin:

    You do not need to worry about any other supplements re. COVID.

    The only thing, and I do not have any clinical evidence for this, is stop using Quercetin a couple of weeks before getting the vaccine and for about a month afterword because I think may negate the benefits of the vaccine.
