Other Ingredients (6)

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

Ascorbyl PalmitateAntioxidant

Fat-soluble form of vitamin C used as preservative

Gum AcaciaBinder

Natural plant gum (acacia) used as a binder, stabilizer, and emulsifier in foods and supplements

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.
