Australia and New Zealand adopted the Slip-Slop-Slap campaign about 30 years ago.
They have been “protecting” themselves with sun screen at all times of the day, not just the middle of the day.
As a result, they have gotten very little vitamin D from the sun.
In Dec 2011 Australia reported 73% of population had less than 30 nanograms of vitamin D based on a study made in 2000
In March 2012 New Zealand reported 32% of population had less than 20 nanograms of vitamin D based on a study made in 2009
80% of Australia and New Zealand will have < 30 nanograms of vitamin D
- dark skin
- high latitude (far from the sun)
- 20 additional reasons/groups
Would have been nice to have had a sunscreen which blocked just UVA,
Unfortunately, most suncreens block both UVA and UVB
Some sunscreens block UVB more than UVA - the exact opposite of what is wanted
Sunscreen in some pills may block UVA but not UVB - which would be GREAT!!
These pills might provide more of the wanted spectrum (UVB) instead of the actual sunscreen spectrum (UVA)

Perspective: The Middle East has even less Vitamin D
Many people in the Middle East now have less than 10 nanograms
- Dark skin (natural sunscreen)
- concealing clothes (wearable sunscreen)
- very hot sun
- air conditioning, etc.
