Vitamin D status (absolute) in response to 12-week supplementation intervention. Panels represent: a) total serum 25(OH)D, b) serum 25(OH)D2 and c) serum 25(OH)D3 concentrations taken at baseline, week 6 and week 12, respectively. * = significant difference within group compared to baseline (p ≤ 0.001); # = significant difference within group compared to week 6 (p < 0.05); a = D3 significantly different to D2 and PL at timepoint (p ≤ 0.01); b = D3 significantly different to PL at timepoint (p = 0.006); c = D2 significantly different to PL at timepoint (p = 0.046); d = D2 significantly different to D3 and PL at timepoint (p ≤ 0.001)
