4 months ago I started having rashes at random moments. I never understood what it was. Now it looks like it's a retinol supplement I was taking sporadically. I know I don't tolerate pumpkin and carrots very well, and I also know I was severely vitamin-D deficient after spending 3 weeks in the dark 1 year ago.
When I upped my vitamin-D dose, the rashes didn't occur as often. I experimented for 2 days now, and I haven't had any problems.
Is it possible that the beta-carotene in pumpkin etc. competes with vitamin-D absorption?

Two different things going on here, from what I can see.
Not tolerating pumpkins and carrots may be FODMAPS intolerance.
Yes, Vitamin D & A can compete for some of the same receptors. Best to get your D level tested and supplement/sun to sufficiency (50 - 60 ng/ml.)
IMO, Vitamin A from all sources doesn't need to be more than 10,000 IUs/day. Most Primal/Paleo folk do not need to supplement A--we get plenty from our diet--especially if you are eating liver.
Look up some of the previous questions on Vitamin A toxicity and D:A ratios.
