Ketone Monoesters
These are amazing when you need to be productive on keto. It's my number-1 productivity hack.
These are not exogonous ketones -- they're a different molecule that your brain can directly use for energy.
- NIH Study
- My opinion:
- They give you a rush of energy
- Without knocking you out of ketosis
- No jitters etc...
- No noticeable side-effects (so far)
Products
There are 2 companies that make this stuff, it's about the same price.
Delta G
This is my favorite -- they have a "delta gold" coffee booster that is amazing. Whenever I need to zone in & crush some code, I throw this in a pot of coffee and it gets me where I need to be immediately.
KetoneAid
This one ships faster (from Amazon) and has the same concentration active ingredient, but I don't like it as much. It's less viscous than the delta-g and tastes much stronger (I wouldn't mix it with coffee).
It's great for mixing with salt-water before a workout -- but that's not my primary use-case. Entertainingly, the Amazon product images have a super long embedded video that goes into the licensing drama & family history.
Common Confusion
Another company, HVMN, used to license the IP for this product but no longer has permission to manufacture it.
They have some good exogonous ketone products -- just not the monoesters anymore (at the time of writing, afaict).
Conclusion
I can't say enough good things about Delta-G. It's my top productivity hack.
All of my time sifting through esoteric nonsense is well-spent, if only to have discovered this product.
