Natural Vitamin D Levels

The Maasai are no longer hunter-gatherers but live, along with their cattle, either a settled or a semi-nomadic lifestyle. They wear sparse clothes, which mainly cover their upper legs and upper body, and attempt to avoid the sun during the hottest part of the day. They eat mainly milk and meat from their cattle, although recently they began to add corn porridge to their diet. Their mean 25(OH) vitamin D level was 48 ng/ml (119 nmol/L) and ranged from 23 to 67 ng/ml.
The Hadzabe are traditional hunter-gatherers. Their diet consists of meat, occasional fish, honey, fruits, and tubers. They have no personal possessions. They wear fewer clothes than the Maasai in that the men often wear nothing above the waist. Like the Maasai, they avoid the sun during the hottest part of the day. Their mean 25(OH)D was 44 ng/ml and ranged from 28 to 68 ng/ml.

Had your vitamin D levels measured?  If no, assume you are deficient.  Most of us are.  If your skin is dark, the risk of deficiency is even greater.  If you don't supplement, start.
