Does this pass blood/ brain barrier?/

In 2006 I had a tramatic brain injury (with two skull fractures ) this helps my short term memory. I also carry a note book to write things down. I would say that it does get by the blood brain barrier as well.

If extra strength has the very same ingredient, same mg...how does it differ from regular strenth?

I have noticed more improvement and glad I increased the strength from 10 mg. to 20 mg.

The description states that the protein was originally harvested from a species of jellyfish. How are you obtaining it now?

As stated on the manufacturer's website (see the About page at Quincy Bioscience's) ..."Apoaequorin is a calcium-binding protein originally discovered in jellyfish, now patented by Quincy Bioscience for use in a variety of products to support cognitive function. Apoaequorin is manufactured in a cGMP compliant facility." I thought from the TV ad line "from a jellyfish" they were harvesting it from caught jellyfish, so you were actually eating jellyfish protein, but it appears they are instead manufacturing in a lab the patented protein enzyme that was "discovered in a jellyfish" back in 1962.
