curcumin absorption with piperine or Phytosome

1.21: web.cook/curcumin absorption with piperine or Phytosome:
. some believe black pepper is needed
in order to absorb turmeric's curcumin?
. I once said I was leary of black pepper,
but I researched it again,
and found that pepper's piperine extract
is healthier than whole black pepper .
. another way of absorbing curcumin
is by binding it with phosphatidylcholine .
[6.18: curcumin and MAO-B inhibition:
curcumin may inhibit MAO-B .
"Curcumin (10-80 mg/kg, i.p. in mice) dose dependently
increased serotonin (5-hydroxytryptamine, 5-HT)
as well as dopamine levels (at higher doses),
and inhibited MAO-A (and in higher doses, MAO-B)"
[ Psychopharmacology (Berl) 2008 ].

NOW Bio-Curcumin Phytosome 
"is Curcumin with phosphatidylcholine
that clinically demonstrates
increased absorption and bioavailability,
as compared to standard Curcumin extracts.
[just like black pepper's piperine?]
Clinical studies also show that
Bio-Curcumin Phytosome provides
potent antioxidant activity, and
can support a balanced inflammatory response" .
the helpful pepper extract is piperine:
Bioperine, a standardized piperine composition
derived from black pepper extract.
Made by Sabinsa, it is a standardized extract
from the fruit of Piper nigrum (black pepper)
or Piper longum (long pepper).
It contains 95 percent piperine . Sabinsa claims
that Bioperine has been shown in clinical research
to increase the absorption of nutrients
in nutritional supplement formulations.
black pepper has more than piperine:
whole black pepper may be carcinogenic
via some procarcingenic constituents such as
safrole and tannins, and some terpene compounds.
These procarcinogenic effects were noted with
topical application.

Black pepper [piper nigrum]: Evidence of carcinogenicity
so the the piperine in pepper
is not among the possible carcinogens;
are phospholipids are better than piperine?

piperine works like this:
. curcumin cannot be utilized due to
its rapid metabolism in the liver and intestinal wall.
. piperine is a known inhibitor of
hepatic and intestinal glucuronidation
. substances resulting from glucuronidation
are typically much more water-soluble .
. in summary,
piperine works by keeping the curcumin less water-soluble;
similarly, phospholipids may work by
making the curcumin more fat-soluble,
which might have the same effect as less water-soluble ?
