One exciting area of genomics is in understanding how our bodies respond to the foods we eat.
Some have a better ability to absorb vitamins than others. This is because our bodies are able to produce proteins that interact with vitamins to function. Some people have inherited disorders which require them to take supplements – Such is the case for people born with Vitamin D deficiency.
For most, a genomic test can tell you which supplements you should take for optimizing your health/wellness.
