The studies are purposefully deceitful. For example, [This shit](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6226111/#!po=32.9545) >> In urine, 26Al was detected in the first day and continued for at least 44 days. Most of the urinary excretion occurred over the first 2‐week postexposure. Of the applied aluminum, 0.0082% and 0.016% was eliminated in urine from the male and female subjects, respectively. Based on this, following correction for 85% renal excretion,11 Flarend et al.4 estimated that 3.6 μg would be absorbed from the single application of antiperspirant, equivalent to 0.012% of the applied dose. Extrapolating this, we can see that its actually .08% being absorbed, or 24 μg. Applied twice per day as is common, you could be dosing yourself with 48 μg. The study also states that there were no observed differences in Al concentration in urine between those using Al laced deodorant vs control. This seems to indicate an upper bound on Al excretion via urine, so if applied every day it will start to build up more rapidly as your body fails to rid itself of the ever increasing levels of aluminum. Notice also how the study was funded by a cosmetics company. Totally no conflict of interest there. It is also used in: Processed foods Materials and articles such as: Aluminum-containing food packaging Aluminum foils Cooking utensils and baking trays Cosmetic products (including antiperspirants, sun creams, toothpaste) Drugs (antacid agents). >> The tolerable weekly intake (TWI) set by the European Food Safety Authority (EFSA) of 1 mg aluminum/kg body weight (BW) in a 60-kg adult is in some individuals already exhausted or slightly exceeded as a result of estimated daily alimentary aluminum exposure of 1.6–13 mg (0.2–1.5 mg/kg BW/week) (5) (table 1). Relative exposure in children is higher at up to 2.3 mg/kg BW/week. Compounding doses from shampoo, deodorant, toothpaste, and sunscreen one could quickly start to push above the ‘safe’ levels of Al concentration. Add in drinking water, which can have up to .5mg/L and other processed foods and you’re getting to critical levels. I dont have time to continue this so make of it what you will.
