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.
Rice FlourFiller
Rice-based ingredients carry risk of inorganic arsenic contamination (FDA and Consumer Reports). Rice accumulates arsenic from soil at higher rates than other grains. Used as a cheap filler — adds nothing beneficial.
Magnesium StearateLubricant
A salt of stearic acid used as a lubricant in tablet and capsule production
Silicon DioxideAnti-caking
Fine silica powder used to prevent clumping
Microcrystalline CelluloseBinder
Plant-derived cellulose used as a binder and filler in supplements
Oat FiberFiber
Insoluble dietary fiber from the outer hull or bran of oat grains; primarily cellulose and hemicellulose, low in beta-glucan compared to oat bran soluble fraction
How to Take It

Take with plenty of water. Fiber binds other things in the gut, so give it a 1–2 hour gap either side.

Keep it away from medication and mineral supplements
