Benefits of Vitamin D

vitamin d

People in Ireland are most vulnerable to Vitamin D deficiency  

“Ireland’s geographical location and lack of exposure to sunshine Vitamin D leaves people living in Ireland very vulnerable to vitamin D deficiency”, said Professor Michael Holick, world renowned global expert on Vitamin D.  “The importance of vitamin D for bone health and a variety of other serious conditions at all life stages cannot be underestimated. Ireland's northerly latitude, means little or no UV light is available between October and March in particular, this means that people living in Ireland must ensure they are getting all the vitamin D they need through their diet”.
With regard to incorporating Vitamin D in the diet Professor Holick recommends sources such as liver oil, oily fish and sun dried mushrooms or fortified foods such as Avonmore Super Milk.  
Avonmore Whole and Low Fat Super Milk is a rich source of Vitamin D. Just one 250ml glass is fortified with 5 micrograms of Vitamin D - that’s 100% of the EU recommended daily intake of Vitamin D for adults.  Included as part of a healthy balanced diet, Avonmore Super Milk is a great choice for you and your growing family.
Facts about Vitamin D:
•   Vitamin D is a fat-soluble vitamin that helps our bodies use calcium to build and maintain strong bones and teeth. 
•   Vitamin D also helps to regulate cell division, normal muscle function and supports the function of the immune system.
•    Vitamin D is known as the ‘sunshine vitamin’ because our bodies can make it from the sun. When sunlight hits our skin, the ultra-violet (UVB) sunrays are used to make vitamin D.
•    From October to March, in countries at a latitude greater than 42° North, little or no vitamin D can be produced due to the quality and quantity of sunlight – Ireland’s latitude is 51-55° North.
