Other Ingredients (5)
MaltodextrinBinder
Spikes blood sugar faster than table sugar (glycemic index 85–105). Research links it to gut bacteria changes that may promote intestinal inflammation (Nickerson et al. 2015). Used as a cheap filler — adds nothing beneficial.
Silicon DioxideAnti-caking
Fine silica powder used to prevent clumping
Capsule ShellCapsule
Generic capsule shell where the label does not specify the material. Common materials are hypromellose (HPMC) for vegetarian capsules and gelatin for traditional capsules — both are GRAS-listed and safe. Fish gelatin and pullulan variants also exist.
Gum AcaciaBinder
Natural plant gum (acacia) used as a binder, stabilizer, and emulsifier in foods and supplements
Sodium Stearyl FumarateLubricant
A standard tablet/capsule lubricant, often used in place of magnesium stearate.
How to Take It
Best taken in the evening
Take 30–60 minutes before bed. It's a circadian signal, not a daytime supplement. Take it between meals, away from food.
On an empty stomach
Keep it away from protein-heavy meals
Space it a couple of hours from SAMe
On the label
Take 2 capsules before bedtime with/without food or as directed by a qualified health care practitioner.
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.
