Nutritional Genetic Testing

Nutritional Genetic Testing

The coded messages of your DNA are billions of letters (nucleotides) long. Personalized nutrition companies only care about a few of your DNA letters and can tell you which "variant" you have at each of those locations (known as SNPs) along your DNA strands.

Genetic testing companies can learn what SNP variants you have by supplying them with a vial of spit.
