My skin looks quite yellow (bilirubine was OK). So I was wondering if it might be something else that doesn't get converted caused by a nutritional deficiency?
Niacin or niacinamide can cause this but only if you take massive doses so that's probably not it.
I asked Ray about this some time ago and he suggested consuming liver. I can report that it worked well. Apparently, the high levels of vitamin B12 in liver facilitates the conversion carotene to retinoids.
thx i'll do it more consistenly... yesterday i had some liver, but it was two months ago... i immediately noticed relief from dry skin...
probably carotene that is not converted to vitamin A but stored in the skin. Look at your palms, are there any yellowish spots there? If so, it is a classical sign of hypothyroidism.
TSH was 0.8...
Yes it can definitely be a sign of low thyroid. At the worst point of my hypothyroidism my mom had remarked that my skin colour had changed to be more yellowish... I didn't know it was connected at the time but since I've increased my NDT dose this year, my skin changed to more pink again. More healthy looking, less sallow.
