Erratum to: A double-blind, randomized clinical trial of dietary supplementation on cognitive and immune functioning in healthy older adults

Correction

Since publication of this article [1], the authors have noted three inaccuracies in their report which they would like to amend. The details of these, and the appropriate corrections are detailed below:

• 1. The Placebo group bars in Figure two (Figure 1 here) were incorrect. The corrected version of this figure can be seen in Figure 1. This correction does not alter the results or interpretation.

• 2. At the beginning of the discussion, it was stated that the TMT-B time score showed an improvement of 68% after 3 months. This value is incorrect, as the correct value is 18%. While, this change is large it does not change the interpretation or other discussion points.

• 3. In the Methods section Intervention and Randomization on page 3, the amount of daily vitamin D delivered from the Catalyn should be 416 IU/day, not 312 IU/day. This has no consequences on the results, but improves accuracy of study design reporting.
