Beta-carotene accumulation in serum and skin
Open accessAbstract
The accumulation of beta-carotene in serum and skin was evaluated in human volunteers. A single 51-mg dose of beta-carotene given in the absence of dietary fat resulted in no detectable change in serum beta-carotene. The same dose administered with 200 g fat increased serum beta-carotene 2.5-fold at 40 h. Similarly, administering beta-carotene daily in three divided doses with meals raised the serum beta-carotene concentration three times as high compared with the same total dose administered once a day; both regimens had the same time constant for serum accumulation; 9-10 d. Remittance measurements of skin color demonstrated that the accumulation of beta-carotene in skin was delayed by up to 2 wk compared with serum accumulation. These data indicate that beta-carotene absorption requires dietary fat and is enhanced by administering with meals but there is a long time constant for serum (10 d) and tissue (several weeks) accumulation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
