This extract concentrates two active compounds from magnolia bark: honokiol and magnolol. Standardization delivers consistent amounts that many people find promote a calm state. The extract interacts with GABA receptors, a mechanism that scientists link to relaxation.
You can take it in capsules or tablets, usually with food to improve absorption. Some people use it during the day to ease occasional stress. Others take it before bed to support the onset of sleep.
Caution is needed. The extract can cause drowsiness and may intensify sedation from alcohol or sedative drugs. Higher doses increase this risk. Speak with a healthcare provider before using it alongside any prescription medication.
