How should an adverse reaction to retinyl (2400 iu orally) be interpreted? I experienced numb feet and poor sleep quality with vivid dreams. Up until this I have been supplementing with beta-carotene (25,000 iu) for three of months. I don't have any bad snp's for beta-carotene conversion, hypothyroidism nor orange skin tone. Could my Vitamin A levels be too high or too low?
Hard to say without a test for blood vitamin A levels but poor sleep with vivid dreams suggests GI irritation. I would try topically and see if this changes the effects.
