Thanks for that, Chris. Good to know. I do not take any supplements.
My approach has always been to get my nutrition 100% from food. I am 75 years old and have been a vegetarian since I was 24 years old, so that is 51 years. I get excellent exercise, predominantly from walking 5+ miles a day.
When I saw the word Older in the title, that called out to me.
I am going to my local all-purpose drug store [a bit like your Boots] for the ZMA; I have located a nearby shop that sells the lion's mane.
I just realized I have to questions for you and would appreciate your reply once again, if you have a moment:
1. Are there particular dosages [usually in mg.] that I should be looking for?
2. Does time of day matter, along with empty stomach/full stomach?
Many thanks.
