They are made through a special deep-embedded technology using biofilm made from phospholipid,cholesterol and protein  to microencapsulated the nano-size particles of vitamins,nutrients and immune factors,to form the self-assembled nano particle with diameter size from 30 to 100 nano-meters.

Through the direct mucosal path,absorption of nano liquid vitamins is more quick and average peak-time is much short. Supplement of nutrients into the animal body is much faster. This is especially meaningful for animal under stress conditions. In the other hand,the absortion can by pass the influence caused by bio- reaction in stomach and intestinal ( as bile,secretion,eating, fat,etc), the pharmacokinetics is more stable. So individual difference caused by liver illness and fat absorption obstacle is very small.
