hpkrazydesi Excess carotene in what way? sorry if thats a stupid question +

davidw this is directly from Goljan "Dietary β-carotenes and retinol esters are sources of retinol. β-carotenes are converted into retinol. (a) Increased β-carotenes in the diet cause the skin to turn yellow (hypercarotenemia). Sclera remains white, whereas in jaundice the sclera is yellow, which can be used to distinguish the two conditions. (c) Vitamin toxicity does not occur with an increase in serum carotene" +4

davidw β-Carotenes are present in dark-green and yellow vegetables. +

I actually think he might have iron-deficiency anemia that can be described as pallor or "yellowing of the skin." He does not have jaundice (anicteric sclera) Patients who are strict vegans can develop iron deficiency. The best way to correct this is to encourage a dietary change

I guess he's taking B12 supplements, otherwise he would have a symptomatic deficiency, right?
