Not quite. I've been taking Beta-hydroxybutyrate (BHB) salts in powder form, mixed with water. Here is some interesting literature discussing its benefits as a metabolic regulator of proteostasis in aged and Alzheimer-diseased brains:
I personally take it to manage brain fog due to long-Covid.
This is why I come to HN.
Have you tried a ketogenic diet? Ketones from your own fat cells for free.
did it help? also, before covid did you not have brain fog?
are you taking BHB along with being on a ketogenic diet or do you else eat carbs?
I use that as well. I found that it was a great way to slowly ween myself off caffeine while avoiding the caffeine withdrawals. My sleep is improving a little and I remember more dreams, not sure why.
Interested to know if this ends up helping you long term, thanks.
