For those of you who don't know: 23andMe is a genetic testing service that looks at 1,000,000 Single Nucleotide Polymorphisms in you genome. I am using it primarily for maximizing health, though it also serves as an ancestry tool.
I believe that knowing your genetic background is crucial to long-term health. Different supplements will have a different effect depending on genes and gene expression. By knowing what genetic factors you are predisposed to, you can maximize the efficiency of your supplement regimen.
