Prevalence of vitamin D insufficiency/deficiency has been noted in athletic populations, although less is known about recreationally active individuals. Biofortification of natural food sources (e.g. UV radiated mushrooms) may support vitamin D status and is therefore of current scientific and commercial interest. The aim of this study was to assess the impact of a mushroom-derived food ingredient on vitamin D status in recreationally active, healthy volunteers. Twenty-eight participants were randomly assigned to either 25 μg (1000 IU) encapsulated natural mushroom-derived vitamin D ; matched-dose encapsulated vitamin D or placebo (PL) for 12 weeks. Venous blood samples were collected at baseline, week 6 and 12 for analysis of serum 25(OH)D and 25(OH)D using liquid chromatography mass spectrometry. Habitual dietary intake and activity were monitored across the intervention. Vitamin D status (25(OH)D ) was significantly increased with vitamin D supplementation from 46.1 ± 5.3 nmol·L to 88.0 ±of a UV radiated mushroom food ingredient was effective in maintaining 25(OH)DTOTAL in healthy, recreationally active volunteers. This may offer an adjunct strategy in supporting vitamin D intake. However, consistent with the literature, the use of vitamin D3 supplementation likely offers benefits when acute elevation in vitamin D status is warranted. Foot problems are likely to contribute to falls risk in older adults. Foot and ankle exercises may be beneficial, but uptake may be influenced by cultural factors. Few studies have explored the views of older adults from different cultural backgrounds about foot-specific falls risk factors, and foot and ankle falls prevention exercises. To explore the views of Scottish and Portuguese community-dwelling older adults who have experienced a fall, about any foot risk factors for falls, and foot and ankle exercises.
