Your comments are clear and concise.

Hopefully more members will do their own research
before spending their hard earned monies.

It is frontier wild west out there LOL
Any nutrient, any supplement should be rigorously
researched: it is painstaking, bewildering and
takes up time, but absolutely necessary.

There is no comment or advice on this forum which
will be a magic bullet, it is a guidepost to begin
your own question and answer search.

collagen is an example: I spent months researching
the different types: hydrolized, denatured versus
native, which type benefits bone formation better,
marine vs bovine, what brand, what format, amount.
which are certified by good health practices, GMP
or other.
A month ago, as I was getting closer to deciding
what to buy:
I came across a report that collagen will add to breast density,
which vexed me. I have dense breast.
I asked a nutritionist I work with, to verify this
information. She found studies that confirm this.
If you have dense breast, this should be something to
consider before taking collagen.
The other alternative - I now need to investigate is
creatine.
Will it do more or less what collagen does, for bone
formation - with
certain circumstances, for example exercize.
For people with sensitive gut, (I have IBS)
creatine might be a challenge.
Dr. Patrick and Dr Stacy Simms: both
advocate strongly for creatine for women and
Omega 3.

As you say in your comments, Persa, when you
are doing complementary activities or supplements,
how do you know which is helping.

I wrote a few months ago, that I was not taking any
drugs in spite of 'severe osteoporosis' and concentrated
on diet and moderate exercize.
My dexa after a year were:
spine improved 5.6%
hips improved 6.4%

Moderate: no jumping, no heavy weights.
I realize some people have physical limitations, some
are unable to do much exercize.
But small increment, done persistently overtime,
will yield some good results.
