iodin

Halogens are fluorine, chlorine, bromine, iodine. All common and cheap.

If sanitizing your underarms was sufficient to get rid of odor and sweat indefinitely, then a big iodine swab would do the job faster and even cheaper.

Other minerals such as Magnesium, iodine and selenium have been shown to have a positive effect on mental health but are not sourced well enough in modern diets. Also indicated for energy and mental function are B Vitamins.

The relevant radioactive isotopes are mainly caesium 137, iodine 131, and strontium 90 [1]. When they decay into other elements, they release beta- and gamma radiation, which can damage nearby cells if ingested into the body.

The article treats the belief in supplements entirely as a case of well-nourished people pursuing quack fixes, ignoring scientifically credible practices such as food fortification using iodine and folic acid, the widely-known connection between vitamin C and scurvy, the use of iron supplements to treat anemia, and the historical experience with real malnutrition. The article makes it sound like a ludicrous idea that snuck into the public consciousness via the senility of Linus Pauling in the late 1960s, but vitamin supplementation makes much more sense as an attempt to continue applying a historically successful formula of improving human health by identifying previously unrecognized dietary deficiencies and correcting them.
