As answered by people managing FormulaSignal and Splitwise.
FormulaSignal's answer
FormulaSignal keeps dated copies of supplement labels published by brands and compares declared amounts line by line, so you can see when a formula quietly changed. It tracks 1,249 products from 152 brands (and growing), and every check is shown, failed ones included.
FormulaSignal's answer
Lab-testing and review sites tell you what a product contained when they tested or reviewed it. FormulaSignal watches the label over time and emails you when a confirmed change hits a product you take, so you know before you reorder. The Locker is free for 3 supplements.
FormulaSignal's answer
People who take supplements regularly, like pre-workout, protein, fish oil and multivitamins, and want to know if the formula they rely on has changed before they buy again.
