ErythritolSweetener
Witkowski et al. 2023 (Nature Medicine, PMID 36849732) reported elevated plasma erythritol associated with major adverse cardiovascular events (MACE) in two cohorts (n=4,000+), with in-vitro and ex-vivo evidence of enhanced platelet aggregation. Replication is ongoing; FDA and EFSA have not changed their safety positions, but the signal is real and the additive is purely cosmetic. Better-established concern: GI tolerance — single doses above ~50 g cause osmotic diarrhea. Lower threshold for children.
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.
AnnattoColorant
Natural yellow-orange colorant derived from the seeds of the achiote tree (Bixa orellana)
Beta-Carotene (color)Color
Beta-carotene used in small amounts as a colorant/antioxidant.
LycopeneAntioxidant
A red carotenoid pigment/antioxidant, typically sourced from tomato.
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.
Tapioca FiberFiber
Soluble fiber derived from tapioca, used as a bulking agent and prebiotic fiber filler
Citric AcidAcidulant
Natural acid derived from citrus fruits
