5-HTP is a direct precursor to serotonin, which the body converts via decarboxylation to support serotonin levels involved in mood and sleep-wake regulation.
Caution: May interact with medicines that affect serotonin; avoid combining with antidepressants or other serotonin-supporting supplements because excessive serotonin activity may cause adverse effects.
Calcium acts as a cellular signalling mineral that supports normal nerve transmission and muscle function.
Caution: Take with food if you experience stomach upset, and separate from certain medicines if advised on their labels due to potential absorption interference.
5-HTP supplies the direct building block for serotonin, while calcium supports normal nerve signalling that underlies neurotransmitter activity.
Label Warning: Consult a healthcare professional before use if pregnant, nursing, under 18, have a medical condition, or are taking medication, including for depression, migraines, Parkinson’s disease, or psychiatric disorders. Do not use with other supplements containing L-tryptophan or 5-HTP. Stop use if adverse reactions occur.
Who should be cautious: People taking antidepressants, migraine medicines, Parkinson’s medicines, or psychiatric medicines may need extra caution due to potential serotonin-related effects.

As this product contains 5-HTP, it may interact with SSRIs, SNRIs, or MAOIs; consult a healthcare provider before combining with these or any medications that may interact.
