Rather than DNA methylation, GlycanAge looks at glycans—molecules that modify proteins and are associated with inflammation. Different glycan measurements, Lauc explains, can correspond to different lifestyle factors, such as diet or exercise. But there’s a limit to what the test alone can show. GlycanAge offers a consultation for people who take its test, and Lauc strongly recommends people take this up. That way, a doctor can learn about your particular lifestyle habits and better interpret what the results may reflect, and which changes you may wish to make. Lauc was able to see the impact of stress on her own results: Her biological age increased around the time her company was engaged in a fundraising round. She took a break, worked remotely, and picked up meditation, and after a while her results improved.
