St. John's Wort: Interactions To Know

Published September 12, 2026

St. John's Wort is one of the two ingredients in Marycept that genuinely deserves a careful read before you start, so here's the plain version.

What It's Included For

St. John's Wort is a traditional botanical included in Marycept's formula to support everyday mood balance.

Why It Needs Real Caution

St. John's Wort is well documented to interact with a range of medications. It can reduce the effectiveness of hormonal birth control, blood thinners, and certain immunosuppressants. Combined with antidepressants (SSRIs, MAOIs) or migraine medications, it can increase the risk of serotonin syndrome, a serious condition.

What To Do About It

If you take any prescription medication, talk to your doctor or pharmacist before starting Marycept — bring the label with you so they can see exactly what's in it.

Our Take

This isn't a reason to panic, but it is a reason to have one conversation with a professional before your first capsule.
