Background: <\/strong>
\nCarotenoids and tocopherols, known to be efficient antioxidants and capable of scavenging reactive oxygen species generated during photooxidative stress, may protect the skin from ultraviolet light-induced erythema, beta-Carotene is widely used as an oral sun protectant but studies on its protective effects are scarce.<\/p>\n

Objective: <\/strong>
\nThe objective of this study was to investigate the protective effects of oral supplementation with carotenoids and a combination of carotenoids and vitamin E against the development of erythema in humans.<\/p>\n

Design: <\/strong>
\nA carotenoid supplement (25 mg total carotenoids\/d) and a combination of the carotenoid supplement and vitamin E [335 mg (500 IU) RRR-alpha-tocopherol\/d] were given for 12 wk to healthy volunteers. Erythema was induced by illumination with a blue-light solar simulator. Serum beta-carotene and alpha-tocopherol concentrations and skin carotenoid levels were assessed by HPLC and reflection photometry.<\/p>\n

Results:<\/strong>
\nSerum beta-carotene and alpha-tocopherol concentrations increased with supplementation. Erythema on dorsal skin (back) was significantly diminished (P < 0.01) after week 8, and erythema suppression was greater with the combination of carotenoids and vitamin E than with carotenoids alone.<\/p>\n

Conclusion: <\/strong>
\nThe antioxidants used in this study provided protection against erythema in humans and may be useful for diminishing sensitivity to ultraviolet light.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-57615","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"STAHL W,UNIV DUSSELDORF,INST PHYSIOL CHEM 1;POB 101007;D-40001 DUSSELDORF, GERMANY.wilhelm.stahl@uni-duesseldorf.de\"","annee":"2000","mois":"3","numero":"71:3","page":"795-798","auteurs":[{"ID":49775,"post_author":"0","post_date":"2018-12-04 05:02:32","post_date_gmt":"2018-12-04 04:02:32","post_content":"","post_title":"Helmut Sies","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"helmut-sies","to_ping":"","pinged":"","post_modified":"2018-12-04 05:02:32","post_modified_gmt":"2018-12-04 04:02:32","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/helmut-sies\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":49317,"post_author":"0","post_date":"2018-12-04 04:54:53","post_date_gmt":"2018-12-04 03:54:53","post_content":"","post_title":"Stahl","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"stahl-2","to_ping":"","pinged":"","post_modified":"2018-12-04 04:54:53","post_modified_gmt":"2018-12-04 03:54:53","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/stahl-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":57612,"post_author":"0","post_date":"2018-12-04 07:41:55","post_date_gmt":"2018-12-04 06:41:55","post_content":"","post_title":"Heinrich","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"heinrich-4","to_ping":"","pinged":"","post_modified":"2018-12-04 07:41:55","post_modified_gmt":"2018-12-04 06:41:55","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/heinrich-4\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":57613,"post_author":"0","post_date":"2018-12-04 07:41:55","post_date_gmt":"2018-12-04 06:41:55","post_content":"","post_title":"Jungmann","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"jungmann","to_ping":"","pinged":"","post_modified":"2018-12-04 07:41:55","post_modified_gmt":"2018-12-04 06:41:55","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/jungmann\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":57614,"post_author":"0","post_date":"2018-12-04 07:41:56","post_date_gmt":"2018-12-04 06:41:56","post_content":"","post_title":"Tronnier","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"tronnier","to_ping":"","pinged":"","post_modified":"2018-12-04 07:41:56","post_modified_gmt":"2018-12-04 06:41:56","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/tronnier\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":44192,"post_author":"0","post_date":"2018-12-04 03:19:18","post_date_gmt":"2018-12-04 02:19:18","post_content":"","post_title":"AMERICAN JOURNAL OF CLINICAL NUTRITION","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"american-journal-of-clinical-nutrition","to_ping":"","pinged":"","post_modified":"2018-12-04 03:19:18","post_modified_gmt":"2018-12-04 02:19:18","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/american-journal-of-clinical-nutrition\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\nCarotenoids and carotenoids plus vitamin E protect against ultraviolet light-induced erythema in humans -
