Caramel ColorColor

Class III and IV caramel colors contain 4-methylimidazole (4-MEI), classified by IARC as Group 2B (possibly carcinogenic to humans) in 2011 (Monograph Vol. 101). California Prop 65 lists 4-MEI as a known carcinogen; products delivering >29 mcg/day require a cancer warning label. NTP TR-535 (2007) found 4-MEI caused lung tumors in mice. Major cola brands (Coca-Cola, Pepsi) voluntarily reformulated 2012-2014 to reduce 4-MEI below California thresholds. Because labels never specify Class I (sugar + heat only, safer) vs Class III/IV (ammonia-process, contains 4-MEI), consumers cannot verify which they're consuming. Combined with the additive's purely cosmetic purpose, the risk:benefit ratio is unfavorable for any supplement.

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.
