Has anyone tried the awesome foursome as a treatment and if so, any positive feedback? The awesome foursome comprise: l-carnitine, d-ribose, magnesium and CoQ10. These are essential to the ATP cycle and fundamental to cellular energy metabolism. There is quite a lot of positive promotion of the awesome foursome on the web. I note that Freddd recommends lcarnitine (fumarate) and d-ribose as 'possibly critical co-factors'. Q: Why is fumarate the preferred form of l carnitine as opposed to acetyl l carnitine? Q: Has anyone had any experience with phosphatidylserine? I have heard that this is very beneficial combined with d-ribose. I plan to embark on the awsome foursome and will try the phosphatidylserine as I need to get my cortisol down (it is very very high) and that is one of about five supplements that I will order to attempt to get the cortisol (night time) down. Thanks in advance for your thoughts and opinions.
