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.
Titanium DioxideColorant
Banned in the EU (2022) over concerns that its ultra-fine particles may damage DNA in gut cells. Still allowed in the US. Used only for white coloring — provides no health 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.
MannitolSweetener
A FODMAP sugar alcohol that can cause GI distress (bloating, gas, diarrhea) at higher doses. Supplement amounts are typically small, but individuals with IBS or sugar alcohol sensitivity may react even at low doses.
Silicon DioxideAnti-caking
Fine silica powder used to prevent clumping
Soy LecithinEmulsifier
Widely used emulsifier derived from soybeans
BeeswaxCoating
Natural wax produced by honeybees, used as a coating and binding agent in softgels and tablets
Dicalcium PhosphateBinder
Calcium and phosphorus compound used as binder
