MannitolSweetener
A FODMAP sugar alcohol that can cause GI distress (bloating, gas, diarrhea) at higher doses. Supplement amounts are typically small, but individuals with IBS or sugar alcohol sensitivity may react even at low doses.

Magnesium StearateLubricant
A salt of stearic acid used as a lubricant in tablet and capsule production
GelatinCapsule
Protein derived from collagen, used in traditional capsule shells
How to Take It
Best taken in the morning
Many people prefer it earlier in the day; there's no evidence timing changes anything. Absorption is fine with or without food.
With or without food
Label directs 2 servings — keep one for the morning
On the label
For adults, take two (2) capsules two times daily, preferably with meals.
General guidance based on the ingredients, not a substitute for the label or your doctor.
