DHEA

Hi
I am new to this forum so I hope its ok to post this. My dad has had parkinsons diagnosis for ten years. Recently it has got worse. He takes his prescribed meds and also melatonin at night to help with insomnia which has worked wonders.CBD oil didnt work for him.
I have been researching DHEA and its role in age related disease.I have me/cfs & fibro so have started taking it and feel much better.
I have read some articles on how DHEA can help Parkinsons and I am very excited.I’d like to ask if anyone on this forum has tried it? Thankyou.
