A NEW LIGHT ON VITAMIN D
Shorter days mean fewer rays, so it’s no wonder that vitamin D deficiency peaks in winter. The ‘sunshine’ vitamin plays a role in bone health and the immune system, and new research shows insufficient D affects muscles, too. A French study revealed that deficiency accelerated muscle loss, while a US review4 found D3 supplements led to strength gains of 1.37-18.7 per cent in athletes. Study dosages ranged from 600-5000iu (15-125mcg), which you are unlikely to achieve through diet. In fact, Public Health England says people should consider a daily supplement in autumn and winter.
