Other Ingredients (4)
Rice ExtractFiller
Rice-based ingredients carry risk of inorganic arsenic contamination. Vague labeling — 'rice extract' does not specify what is extracted or standardized. Used as a cheap filler with no supplemental benefit.
Rice FlourFiller
Rice-based ingredients carry risk of inorganic arsenic contamination (FDA and Consumer Reports). Rice accumulates arsenic from soil at higher rates than other grains. Used as a cheap filler — adds nothing beneficial.
Gellan GumGelling Agent
Microbial polysaccharide produced by Sphingomonas elodea, used as a gelling and stabilizing agent
HypromelloseCapsule
Plant-derived capsule material from cellulose
How to Take It
Best taken in the evening
Contains 5-HTP, so it belongs in the evening. Vitamin B6 is easier on the stomach taken with food.
With food
5-HTP does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.
Keep it away from protein-heavy meals
Space it a couple of hours from SAMe
On the label
Adults take 1 capsule daily with food or as recommended by your healthcare provider.
Do not combine with St. John's Wort
Each of these raises serotonin activity on top of St. John's Wort, and together they can trigger serotonin syndrome — agitation, rapid heartbeat, raised blood pressure. Not without medical supervision.
General guidance based on the ingredients, not a substitute for the label or your doctor.
