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
Hypoallergenic Plant FiberFiller
Plant-derived cellulose fiber used as a hypoallergenic filler, common in Thorne and Pure Encapsulations products
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.
How to Take It
Best taken in the morning
Live strains survive stomach acid best taken with or just before a meal — after a meal is the worst option. Consistency matters more than the clock.
With food
Glutamine 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 hot food or drink
On the label
As a dietary supplement, take 1 capsule, 1-2 times daily, with meals.
General guidance based on the ingredients, not a substitute for the label or your doctor.
