Vitamin D3 is highly recommended, especially if you live in a cold climate where you don’t get at least 10-15 minutes of direct sunlight outside every day.  Vitamin D3 is synthesized by your skin when it is in contact with the sun. Vitamin D3 has been linked to cancer prevention and essentially tells your cells when to regenerate.

Vitamin B12 is another vitamin that should be considered.  Vitamin B12 is almost completely missing from our diets.

Vitamin C is important for keeping your immune system strong.  This vitamin is essential and consider taking relatively high doses.
