Summer may be just on the horizon but as British weather struggles to guarantee sunshine, you may still need foods rich in vitamin D to complement your diet this year.
But it's not only the unpredictable British weather that can prevent us from getting the vitamin D we need. Those who spend little time outdoors, wear fuller-coverage clothing, use a daily SPF, or struggle to synthesise vitamin D naturally may also be advised to take vitamin D in summer. "Here in the UK, you can only absorb vitamin D from about 10 am to 3 pm," says Farzannah Nasser, a certified nutritionist. "Look at your shadow to know if you can - if it's shorter than you, it's at the right wavelength and you can absorb it. If your shadow is taller than you, you won't be able to."
