Mood support; Relaxation support; Serotonin pathway support
Adults with busy, high-stress days seeking gentle mood and relaxation support throughout the day.
Adults take 1 tablet up to two times daily with a meal; do not exceed the suggested amount. Because this is time-release, swallow whole and avoid crushing or chewing.
Formulated without milk, egg, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, sesame ingredients.
5-HTP is a direct precursor to serotonin, which the body converts to support neurotransmitter balance related to mood and relaxation.
Caution: May cause drowsiness or digestive discomfort; avoid combining with antidepressants or other serotonin-boosting products because excessive serotonin activity may be risky.
Calcium supports normal nerve signaling and muscle function and also acts as a tablet excipient source in this formula.
Caution: Take with food if sensitive to minerals; high total calcium intake from multiple products may contribute to constipation.
5-HTP supplies the immediate building block for serotonin, while the time-release matrix and small amount of calcium help deliver a steady intake over time for consistent neurotransmitter support.
Label Warning: Consult a healthcare professional before use if pregnant, nursing, under 18, have a medical condition, or take medications, including those for depression, migraines, Parkinson’s disease, or psychiatric disorders. Do not use with other supplements containing L-tryptophan or 5-HTP. If adverse reactions occur, stop use.
Who should be cautious: People using antidepressants (SSRIs, SNRIs, MAOIs), migraine medications, or Parkinson’s medications may need extra caution due to serotonin-related effects. Those with psychiatric conditions should consult a healthcare professional. Because this product contains 5-HTP, discuss with a healthcare provider before combining with medications that may interact.
Storage: Store in a cool, dry place.
