Read an ebook claiming vitamin A is not a nutrient, but a poison! (It is needed but can build up to toxic levels over time if you greatly overdo it.) I'd been taking 50,000 I.u. a night for years. Had a very scurfy scalp. Then avoided vitamin A supplements for most of a year. Scalp issue came back - symptoms of excess and of deficiency much alike! Got to where I could not sleep near enough hours, would awaken very early and not fall asleep again, after only 4 or 5 hours of sleep at most, every night.

One day I read about a study where people with the lowest levels of vitamin A slept the least hours! I started taking vitamin A again and did much much better. These days if my eyes get uncomfortable, sore, red, I take 4 25,000 unit capsules, then no more until my eyes bother me again. I have a high need for vitamin A, had terrible night vision, calluses on feet, bumpy skin on backs of upper arms before I ever took the stuff. Zinc helps night vision too. Individual needs vary.
