That pine bark extract (pycnogenol ) thing is a little troublesome to research.
Almost every notable website (John Hopkins, WebMd, HealthLine, RXList and a few in the busines of selling it) cites studies that may or could or can show some, this or that, possibly, might, have shown, small study ...... of just about everything malady-wise everyone wants to fix, from diabetes, heart health to leg cramps and kidney function.
That was my hour long first impression of trying to find out more about pycnogenol suplements.
That study set will take some time to iron out.
If it does anything positive for hearing health, I'm all in.
I'm more interested in what minerals or beneficial combinations of minerals I might be missing, that it might supplement, tbh.
Ears are bones when you get down to mechanical functionality, susceptible to similar arthritic hinderments and calcification build ups common with age, so my doctor has told me in the past.
Bones need minerals.
I would like to see someone with a few degrees on the subject pop over and set us forward with usable info.
