Gene Regulation & Gene Expression

Gene regulation is the process that turns genes "on" or "off" depending on what each cell needs. Even though all your cells contain the same DNA, they have different jobs, so they use different genes.

When a gene is turned "on," it's expressed — the cell uses it to make hundreds of copies of a protein. Once there's enough of that protein, the cell signals the gene to turn back "off." This constant communication keeps your body in balance.

Fine-Tuning Gene Expression

In reality, genes aren't simply on or off. Most are fine-tuned to produce a specific amount of protein based on what your body needs. Your environment and lifestyle can shift this fine-tuning, which is why what you eat, how much you exercise, and even your stress levels can influence how your genes are expressed.

Epigenetics: How Your Lifestyle Shapes Your Genes

Epigenetics is the study of how your environment and lifestyle change the activity of your genes — and how those changes can even be passed on to future generations. This is a key reason your genes alone don't determine your health.

Genes + Lifestyle = Your Health Profile

For example, people with certain genetic variants may naturally produce less serotonin, which can make them more prone to some psychological conditions. But serotonin levels can rise through factors like exercise, sunlight, and social connection.

This is how SelfDecode works. We analyze your genes to predict which lifestyle, diet, and supplement recommendations will be most effective for your unique biology — because your health is shaped by both your genes and how you live.
