Simon is a 35-year-old lawyer who works in a large law firm in New York City. He’s noticed that since he turned 30, his body seems to need more time on average to recuperate from illnesses. To top it off, since he started working at the firm about two years ago, he has seemed vulnerable to catching every infectious illness that his co-workers come down with – from a little cold to a full-blown flu. Simon always seems to be coughing, sniffling, and fighting fatigue. He’s also recently developed a skin condition on his face that looks greasy and flaky, and feels irritable most of the time. Although he considers his diet pretty healthy and his lifestyle relatively active, Simon is now thinking of taking vitamin supplements. Do you think Simon might need supplements?
