Absolutely true. I test as I can, as difficult as that can be with a sample size of 1. But the magnesium/calcium supplement combo reliably stopped and restarted my nail-biting through three rounds of taking/not taking the supplements, which is as good a track record as I require. When I started testing my supplements I was not surprised to learn that several that had initially seemed beneficial didn’t provide any sustained benefit.
