That's a pretty broad question but I'll try to give a few options.
First, on the Emiq and Quercefit, I think both ingredients have potential. We've been looking at using one or the other in a couple of upcoming formulas. I do think they have potential but I do view them as supporting ingredients to a formula and not one to base it around. I hope that makes sense.

X-Gels (Arachidonic Acid):
- Arachidonic Acid has been a favorite of many on here for many years.
- Product link and info:

- Tons of positive posts, logs, and reviews on over the years.
Phosphatidic Acid:
- This one is popular but more debated. Some people love it and say it works great, others say they don't get as much from it. I think that's because of several reasons - 1) I do believe it works different for different people (like many things do) 2) When it first came out it was overpromoted and overhyped and it led to way too many false expectations that nothing natural could live up to 3) This kind of goes back to point #2 in that people expect too much too quickly, but Phosphatidic Acid for best results needs to be used for minimum of 8 weeks and best used longer because it really starts to work best when you take it long enough to hit a saturation point.
PEAK02 (if you're after endurance):
- Great clinical studies at UNC Chapel Hill on this ingredient for endurance, VO2 Max, etc.
- Product link and info:

On a personal note, you mentioned Beta Alanine, which is commonly used for endurance. I have a medical condition that hinders my ability to perform as well as normal in endurance activities. I'm not putting down Beta Alanine at all (we sell it ourselves) but PEAK02 helped me a LOT more than Beta Alanine and has become a staple product in my supplement regimen for endurance and for its immune support properties.
There are also a lot of great basic but staple ingredients. That's the focus of our upcoming daily ergogenic is to combine a lot of those staple ingredients into one product for convenience and cost effectiveness.
