A question about the chemical complexity of milk

I have heard that milk is the most chemically complex solution in the world, with over 200 different chemicals and compounds suspended in it. Is this true? If not, what is the most chemically complex substance?
Thanks!

Milk isn’t even in the running. Blood would leave it far behind and even that’s kiddies stuff.

The larger your bucket of solvent the more solute you can add and therefore the richer your potential solution. Because of its bipolar nature water is probably the best solvent available, and the biggest bucket of water available is of course the big briny.

Sea water, which has trace amounts of every element terrestrial element soluble in water (which is pretty much all of them) and the collective leavings of millions of species of sea life, would have to be the winner as far as modern science can acertain.
