The problem01
Why are nerve supplement reviews hard to trust?
Because symptoms like tingling rise and fall by themselves, a review cannot tell you what caused a change.
Pain and tingling can come and go with sleep, activity, blood sugar and medicines. A person who starts a capsule on a good week may credit the capsule. Another may quit on a bad week. Neither review tells you about the next person.
The FTC says anecdotal consumer experiences cannot substantiate what a product does 1. So a review is a story, no more.
Time adds another bias. People who feel better tend to write early and warmly, while those who feel nothing often write nothing. The result is a pile of reviews that leans positive without proving anything. A thread of ten glowing posts tells you less than one plain label.
