Prefer to obtain VITAMIN D from Sun and Food
Natural D is best - Since VITAMIN D levels are so critically balanced with other nutrients, prefer to obtain D3 from sun or food sources, rather than taking unnatural quantities of isolated D3 (or synthetically derived D2) as a supplement.
-Fish -stored in their fat, is VITAMIN D made from the VITAMIN D precursor found in algae. Modern farm-raised salmon are probably poor sources of D, since they are unlikely to have eaten many algae;
-Higher mammals - VITAMIN D is made from precursors in lichen and green grass. VITAMIN D is in the butterfat of ruminant animals that feed on green grass. Like humans, pigs that spend time in the sunlightconvert sunlight to VITAMIN D in their skin, and store it in their fat.
-Eggs - contain VITAMIN D if the chickens have obtained it from insects or fishmeal.
-VITAMIN D is not transferred in breast milk -only VITAMIN D-fortified milk contains any significant amount of VITAMIN D; the best source of VITAMIN D for babies is by exposing skin to the sun -the same as for older children and adults.
