Serum levels of carotenoids vary between region, ethnicity, and sex in the healthy population. Diabetes, hypothyroidism, and liver and kidney disease may alter carotene levels in the body and lead to physical symptoms. Carotenemia may be observed 4–7 weeks after initiation of a diet rich in carotenoids. Processing and homogenizing causes carotene to become more available for absorption. Elevated serum beta-carotene does not necessarily result in carotenosis, but the latter is likely to show up when intake is more than 20 mg/day.
