St. John's Wort & 5-HTP: What To Check Before You Start

By the Quiet Tone Wellness Desk · · 7 min read

In Short

Two ingredients in Quiet Tone's blend, St. John's Wort and 5-HTP, carry documented medication-interaction considerations the label itself doesn't flag.

Knowing these interactions matters more than most ingredient questions in this formula, especially if you take prescription medication.

St. John's Wort

Documented by NCCIH and other authoritative sources for interacting with a wide range of medications by affecting how the body processes them, including certain antidepressants, birth-control pills, cyclosporine, seizure medications, heart medications, HIV medications, cancer medications, warfarin and certain statins.

5-HTP

5-HTP is involved in serotonin activity. If you take an antidepressant or other serotonin-affecting medication, this specific ingredient is worth raising with your prescriber rather than relying on general information alone.

The other calming botanicals

Valerian, Passion Flower and other sedating botanicals in the blend are generally discussed alongside caution around alcohol, sedatives and other central-nervous-system-depressant medications, since combined sedating effects are the general concern.

None of this is a claim that Quiet Tone specifically causes any interaction — it reflects general pharmacology literature on ingredients present in the blend. If you take any prescription medication, this is a conversation for your pharmacist or doctor before you start, not after.

Applying this to Quiet Tone

St. John's Wort and 5-HTP are two of the 18 ingredients in Quiet Tone's blend. Their individual amounts aren't disclosed, which makes a conversation with your prescriber even more important if these interaction categories apply to you.
