Results: Tellwut Top Picks! Vitamin D

Putting vitamin D into the flour we buy could help stop tiredness, muscle aches and even heart failure, according to a study. One in five UK adults has a vitamin D deficiency, according to academics at the University of Birmingham. Things like sun cream, air pollution and full-body clothing often stop people's skin from naturally making the vitamin in the sun. Researchers say adding it to wheat flour could stop 10 million deficiency cases in England and Wales over the next 90 years. They say it could be done for 12p per person, per year.
