In the original publication [1], there were two errors, one in Figure 3 and one in Table 1, both concerning the mistakenly placed decimal points.

Error in Figure and Caption

In the original publication [1], there was a mistake in Figure 3, which shows differences between total 25(OH)D concentrations in serum and BMI in healthy women from the Central Slovenian region aged between 44 and 65, who were included in the study carried out between 1 March 2021 and 31 May 2021 (n = 176) as published. During figure editing, the labels for premenopausal and postmenopausal women were accidentally switched. The first group should be postmenopausal and the second group should be premenopausal.
An error in the mean values and SD of free 25(OH)D was also noticed. Due to mistakenly placed decimal points, the values and SD presented in the graph were higher (e.g., instead of 1.37, the value appeared as 13.7).
Additionally, there was a mistake in the caption of Figure 3. The figure presents differences between total, free, and bioavailable 25(OH)D concentrations. However, in the published version, only total 25(OH)D concentrations are mentioned. For better clarity, the caption has been corrected to include the missing information.
The corrected Figure 3 appears below.

Error in Table

In the original publication [1], there was a mistake in Table 1, which shows population characteristics, vitamin D status, supplementation, and food intake of healthy women, aged between 44 and 65, from the Central Slovenian region, who were included in the study carried out between 1 March 2021 and 31 May 2021 (n = 176). Mean values and SD of free 25(OH)D were presented with wrong decimal point. The corrected Table 1 appears below.
The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
