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.

CarmineColorant

Insect-derived (not vegan/vegetarian) and a recognized cause of IgE-mediated allergic reactions, including documented anaphylaxis. The FDA mandated explicit 'carmine'/'cochineal extract' labeling in 2011 specifically because of these reactions. Not toxic to the general population, but a genuine allergen with no health benefit; plant pigments achieve the same color.

Magnesium StearateLubricant

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

Propylene GlycolSolvent

Liquid used to dissolve and preserve supplement ingredients

Silicon DioxideAnti-caking

Fine silica powder used to prevent clumping

Microcrystalline CelluloseBinder

Plant-derived cellulose used as a binder and filler in supplements

Croscarmellose SodiumDisintegrant

Cross-linked cellulose derivative used as a superdisintegrant

Dicalcium PhosphateBinder

Calcium and phosphorus compound used as binder

How to Take It

Take it anytime

Studied as a twice-daily dose — its effect on bacterial adhesion is short-lived, so one big dose isn't equivalent.

With or without food

On the label

For adults, take one (1) coated caplet daily, preferably with a meal.

General guidance based on the ingredients, not a substitute for the label or your doctor.
