In October 2023 I began taking one capsule of NOW brand vitamin A 25000 IU every second day, until 23rd May 2025, having consumed approaching 300 capsules, averaging 12500 IU daily. I had no inkling that it may be perilous to my liver and my health in general, until an accidental discovery of Dr Garrett Smith and his work on vitamin A toxicity. I am investigating both sides of the argument, which is always a sensible approach. Disclaimer: this is not medical advice, do your own research, take your own responsibility.
