TalcAnti-caking

IARC classifies cosmetic-grade talc not containing asbestos as Group 2B (possibly carcinogenic to humans); perineal talc use as Group 2A (probably carcinogenic). Johnson & Johnson voluntarily withdrew talc-based baby powder from US/Canada in 2020 and globally in 2022 after extensive litigation tied to ovarian-cancer and mesothelioma cases. The 2018 FDA contamination survey found asbestos in 9 of 52 cosmetic talc products tested. As a supplement excipient talc is a pure manufacturing convenience — no nutritional or functional benefit to the user — so the asbestos-exposure risk has no offsetting upside. Safer alternatives (silicon dioxide, microcrystalline cellulose, rice hulls) are widely available.

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.

Medium Chain Triglyceride OilCarrier

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

PolydextroseFiller

A synthetic soluble fiber/bulking agent made from glucose

Silicon DioxideAnti-caking

Fine silica powder used to prevent clumping

Calcium CarbonateBuffer

Common calcium salt used as a buffering agent, filler, or mineral fortification in supplements

Croscarmellose SodiumDisintegrant

Cross-linked cellulose derivative used as a superdisintegrant

GelatinCapsule

Protein derived from collagen, used in traditional capsule shells
