Paprika: the red pigment barely reaches your blood

Most human trials of paprika used a concentrated extract in capsules. In a 12-week randomized trial in 33 healthy adults taking 20 or 100 mg of paprika oleoresin a day, beta-cryptoxanthin and zeaxanthin rose in the blood with dose. Capsanthin, the red pigment typical of paprika, was never detected, and a single-dose study in 9 volunteers found capsanthin and capsorubin very poorly absorbed. The same trial saw no adverse events on blood and urine tests, in a sample too small to catch rare ones. On paper the ground spice looks rich, but a serving is small. USDA lists 2463 ug of vitamin A (RAE) per 3.5 oz (100 g) from a single sample record, which comes to about 50 ug in 2 g of the spice. The UK table gives exactly twice that, 4926 ug, because it converts carotene at 6 to 1 where USDA uses 12 to 1. The harms documented in our sources come from lead added to the spice by fraud and from rare allergy, including one case of anaphylaxis.

The bottom line

The skin trials are small and used capsules. In 46 healthy volunteers, 9 mg of paprika xanthophylls a day for 5 weeks raised the UV dose needed to redden the skin at weeks 2 and 4 compared with placebo, and the abstract gives no size for the effect. In a 4-week single-blind trial, facial skin moisture was higher with the capsules than without, 21.0 against 13.4 units, in a report that names neither the number of people nor the dose. Wrinkles and elasticity did not differ significantly, and brown spots increased from 173 to 190. In the US, supplements do not go through FDA approval the way medicines do, so anyone who takes medication, is pregnant or has a chronic illness should talk to a doctor before taking one. In 21 college students, mostly men, one month of 9 mg a day lowered heart rate at the ventilatory threshold and raised exercise efficiency, in a crossover trial without placebo or blinding. Across two lunch experiments with 86 adults, a higher ratio of hot to sweet paprika in chili or tikka masala slowed eating and reduced how much was eaten at that one meal, with no numbers in the abstract. Paprika extract used as a food color in processed foods is a separate question. In 108,723 French adults followed for a median 8 years, higher intake of this color was associated with a 26 percent higher incidence of type 2 diabetes (HR 1.26, 95% CI 1.08 to 1.46). That is observational data about an additive in industrial food, and it cannot separate the color from the processed foods that carry it. The documented harms from ground paprika in our sources come from contamination and allergy. In Hungary, paprika adulterated with red lead poisoned consumers, and 53 of 141 exposed adults had symptoms such as colic or anemia. The lead was added by fraud, but the people who were poisoned ate it as ordinary ground paprika. FDA names paprika, with turmeric and cinnamon, among the spices to which lead can be added on purpose, likely for economic gain, without giving a frequency. A review of 12 outbreak and case studies named paprika spice among the vehicles of Salmonella Javiana infection, without giving a frequency. Allergy is documented in single cases. A kebab-restaurant worker developed work-related rhinoconjunctivitis from handling paprika and cayenne, and a spice seller sensitized to paprika had anaphylaxis after eating it while tolerating other nightshades. We found no data on pregnancy, children, kidney disease or medicines, and our sources do not say who is most at risk from lead in spices, so that gap is not a sign of safety.
