SNPs Explained
A single-nucleotide polymorphism (SNP) is a variation at one position in your DNA. Most are common, most have small effects, and only a handful change a real-world decision. These articles cover the SNPs that do — the ones in your raw 23andMe / AncestryDNA / MyHeritage file that meaningfully inform medication choice, supplement strategy, lifestyle adjustments, or clinical screening conversations.
