hey dear. i was told that you should take birds nest once every two/three days and it's best to be taken at night whereby the body will best be able to absorb the nutrients from the birds nests.i was at the chinese medical hall yesterday and the lady say eat bird nest is good for our lungs n the baby's lungs. but if you eat it like once in 2 months, its pointless. you have to take like 1 teaspoon of non-concentrated type each day. baby skin will be very nice then.
during my pregnancy, i just took half a bottled of nestural which is bottled birds nest. half a bottle today and the other half two/three days later.
