Vitamin D3

Known as the sunshine vitamin, it’s one of the most important and powerful nutrients for supporting the immune system. Food sources are limited but include:  

• Salmon. 
• Mackerel.
• Tuna.
• Sardines.
• Vitamin D fortified like milk, orange juice and cereals. 

In general, it’s best to get most of your vitamins from food, but vitamin D3 may be the exception to that rule. Talk with your doctor to find out if you need a supplement.
