Other Ingredients (11)

IsomaltSweetener

A poorly-absorbed sugar alcohol that can cause bloating, gas, and laxative effects at higher doses (EFSA notes laxative threshold for polyols). Tolerable for most, but cumulative across products.

MaltitolSweetener

Worst GI tolerance of the common sugar alcohols — laxative effect at doses above ~10–15 g/serving in many adults; threshold is lower in children. Glycemic index (~52) is significantly higher than erythritol (0) or xylitol (~7) — meaningful blood glucose impact at typical serving sizes. The 'sugar-free' marketing claim masks real metabolic effects when consumed in quantity.

Citrus FiberFiber

Dietary fiber derived from citrus peel used as a bulking and texturizing agent.

Medium Chain Triglyceride OilCarrier

Fractionated oils rich in C8/C10 triglycerides used as neutral carrier or anti-sticking agent

Natural FlavorsFlavor

Broad regulatory category of flavor constituents derived from natural sources. Composition is proprietary and not disclosed — 'Natural Flavors' can include several hundred different compounds depending on the target flavor profile, including hexane-extracted constituents and proprietary carrier solvents. 'Natural' is a regulatory definition (21 CFR §101.22), not a safety guarantee.

Beta-Carotene (color)Color

Beta-carotene used in small amounts as a colorant/antioxidant.

Carnauba WaxCoating

Hard plant wax from the carnauba palm used to glaze gummies and tablets

Citric AcidAcidulant

Natural acid derived from citrus fruits
