Other Ingredients (10)

FructoseSweetener

Added free fructose is metabolized in the liver and at habitual intake is linked to elevated triglycerides, hepatic fat accumulation, and insulin resistance; an avoidable sugar load with no supplement benefit.

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.

SucroseSweetener

Added sugars and high glycemic load; dental caries risk

LactoseFiller

A milk-derived sugar used as a filler and binder in tablets and capsules

Magnesium StearateLubricant

A salt of stearic acid used as a lubricant in tablet and capsule production

'Natural' is a regulatory definition (21 CFR §101.22), not a safety guarantee.
