As a Beta Minor I can agree that most of the supplements listed here will have some good effects overall but YMMV and you must also account the prices of supplements vs that of the nutritional foods.
Something I have not seen around here is "Ginkgo biloba". In my late 20's I ran into a young baseball player that was taking Ginkgo biloba gels. Naturally I asked him about it and he said it kept him alert during games. Typically I can bike ride or jog at a slow speed for hours, but to go fast I find myself tiring out more than others. It's always been that way for me and I gave up things as a kid like BMX racing because I couldn't keep up. So one day (20 years ago) I went the GNC at that time and picked up some Ginkgo biloba gels, and I just wanted to be more alert for work. So I took the Ginkgo a few times per-day for a week and felt great. Then my day for work arrived, I loaded up my gear and I got on my bike for a 5 mile ride. I was in for a shock when I flew up the hills like a champion, it was truly something magical to experience pedaling faster and longer and with almost no effort. From that point on I was hooked on this stuff and months later my lab results came back that looked so good my Doctor was asking me if I was taking anything. I had to stop though, maybe I just over did it, but in time I found myself with long periods of insomnia and there was this one time I scratched my leg and it started bleeding for a very long time. All-in-all though, that was many years back and Ginkgo biloba was the one thing that I felt overcame the physical limitations of Thalassemia. *Thinking about getting some Ginkgo biloba, but holding myself back.*
