Vitamin D is the only vitamin that can be made in our skin in with the help of sunshine, more specifically, the ultraviolet B (UVB) rays. During the summer months, we get most of this vitamin through sunshine-skin collab. But from October through to early March, UK sunshine isn’t UVB – rich enough, so we aren’t producing any significant amounts..

A recent report carried out by the Scientific Advisory Committee on Nutrition (SACN), suggests that everyone over the age of 1 needs to consume 10 micrograms (400IU) of vitamin D each day… This advice also applies to pregnant and breastfeeding ladies. You should avoid consuming more than 25µg (1000IU) a day, unless recommended by a doctor or a Dietitian.

NOTE: it’s a fat soluble vitamin, so best if you take your supplement with a meal.
