Frequently Asked Questions

What is Relora and how does it differ from magnolia bark extract?

Relora is a patented combination extract of Magnolia officinalis bark and Phellodendron amurense bark, standardized for honokiol, magnolol, and berberine. It was specifically developed for stress management and has been used in the most rigorous clinical trials (Talbott 2013). Pure magnolia bark extract contains only the Magnolia-derived compounds (honokiol and magnolol). Both are effective, but Relora has more clinical validation for cortisol reduction.

Is magnolia bark safe for long-term use?

Clinical studies of up to 6 weeks show good tolerability with no significant adverse effects. Long-term safety data beyond this period is limited. Unlike benzodiazepines, magnolia bark compounds do not appear to cause dependence or tolerance in preclinical studies, and they have been used in traditional Chinese medicine for centuries. However, periodic breaks are prudent given the limited long-term clinical data.

Can I take magnolia bark with other sleep supplements?

Magnolia bark can be combined with non-GABAergic sleep supplements like melatonin, 5-HTP, or tart cherry. Use caution when combining with other GABA-modulating supplements (valerian, kava, passionflower) as effects may be additive. Start with lower doses of each when combining. Avoid combining with prescription sleep medications or benzodiazepines without medical supervision.
