Seaweed Jelly, some peope call it Sea Bird's Nest. It's collagen is 10 times higher than bird's nest and it's calsium content is 37 higher than fish liver. A packet of Seaweed Jelly (can't remember the weight) is a few RM in organic shop. Not a big packet but you get quite a lot of seaweed jelly. I haven't checked out at other shop.
