Your B-12 spray is good… it is the proper METHYL cobalamin type.
Don’t know if you are on statins or not, but CoQ-10 is good heart maintenance for us ‘mature’ folks… always recommended.
I was somewhat tongue-in-cheek saying “get ready to exercise” as I am aware of your condition. But be prepared for the ‘feeling’ like you want to get out and walk or something when you take the cordyceps. The mushroom enhances the body’s ATP energy carriers and oxygen carriers (which for you is a GOOD thing!) without increasing heart rate or blood pressure like caffeine does. It really is a different ‘energy’ boost feeling… quite strong.
In the reviews, users note that this energy rush wears off sooner as you adapt to using the cordyceps over time… the body adapts and works better and you get ‘used’ to it.
