The best way for us to get good doses of vitamin D is by exposing large areas of our body to direct sunlight for short periods of time, but not for long enough to burn.
Even the best diet can only provide a fraction of the vitamin D that we actually need.
Although vitamin D is stored in our fat cells for use in the shorter winter months, most of us can still benefit from vitamin D supplements winter time as well.
Experts in vitamin D recommend that we should get an average of 4000 International Units (IU) each day.
We can get between 5000 and 10000 IU in a single short session of sun exposure in summer time, compared to only 1000 IU from a single serve of oily cold water fish.
Our modern diet only delivers around 300 IU per day which is far cry from experts daily recommendation.
