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.
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.
Magnesium StearateLubricant
A salt of stearic acid used as a lubricant in tablet and capsule production
Polyethylene Glycol (Coating)Coating
A polyether polymer used as a tablet coating and plasticizer
Silicon DioxideAnti-caking
Fine silica powder used to prevent clumping
Croscarmellose SodiumDisintegrant
Cross-linked cellulose derivative used as a superdisintegrant
CrospovidoneDisintegrant
Cross-linked synthetic polymer used as a tablet disintegrant to help tablets break apart quickly in the stomach
Hydroxypropyl CelluloseBinder
An inert modified-cellulose polymer used as a binder, film-former, and disintegrant.
How to Take It
Best taken in the morning
Contains Yohimbe, which is stimulating — keep it to the morning. Take it with a meal containing fat — the vitamin E in it absorbs poorly without one.
With a meal containing fat
Space it a couple of hours from Iron and Calcium
