I think this is the product T-Matt was referring to:
It contains zinc & hcl as mentioned.
I used Poliquin's hcl for months last summer. It is hydrochloric acid (betaine). Charles believes (through much experience) that almost everyone over the age of 20 is deficient in stomach acid which limits the efficiency of nutrient absorbtion.
He has a protocol to follow to bring back up lower levels. It can take a very long time before this is accomplished.
I ran it for over 2 months and while it definitely helps with digestion and I am sure assists in providing your body with a higher % of the nutrients you eat; I never got the "burning sensation" that is supposed to indicate that you can start reducing the dose. It finally became too expensive for me.
Poliquin's products are pretty much tops. I know Christian Thibaudeau ranks them as one of the few besides Biotest and a Canadian company (XPN) that he would vouche for.
I do not know if this product would significantly help your particular situation.
Another cool procedure Poliquin and his trainees offer is Biosignature, They measure your bodyfat at 8 sites with callipers and they can then tell you which hormones require regulation. For instance (very simplified - they actually use site ratios),
if you have a spare tire - you have excessive cortisol
If you have a belly - you are insulin sensitive
If you carry fat on your chest - estrogen is elevated etc.
They then prescribe training and supplements to restore optimal balance.
You can check out if there is a practitioner in your area on their website.
