How do web developers balance productivity and healthy living?

I’ve been working from home as a web developer, and I also handle some admin tasks. I’ve been doing this for several years now, so most of my day is spent in front of a computer. I try to take regular breaks and do some light exercise to avoid feeling too tired or having eye strain. Recently, some friends suggested that I also try health supplements to support my overall health, especially since we spend so much time looking at screens.

Any web developers here taking health supplements?
What do you take, and do you feel it helps with your energy, focus, or eye health?
